Introduction
World's Most Efficient Lowest Emissions Chiller
Ingersoll Rand EcoWiseTM Portfolio--Trane has always taken a leadership position in environmental stewardship without compromising efficiency, reliability or safety. CenTraVacTM chillers are among the Trane� products within the EcoWiseTM portfolio and can operate with either R-123 or next-generation refrigerants R-514A or R-1233zd, both featuring ultra-low GWPs of less than two.

Environmental Product Declaration--The entire CenTraVacTM chiller portfolio has earned product-specific Type III Environmental Product Declaration (EPD) verification, the first commercial chiller in the world to provide this documentation. This EPD substantiates our environmental claims regarding chiller performance and documents conformance with the stringent third-party certification requirements of the International Standards Organization (ISO) and verified by Underwriters Laboratories in accordance with ISO 14025.
Standard of Excellence--Trane found that the straightest path to achieve the highest efficiency with the best reliability is through simplicity of design. The CenTraVacTM chiller has only one primary moving part--a single rotating shaft supported by two bearings. This direct drive concept minimizes the chance of failure by reducing the number of critical parts--no gear boxes, couplings, extra shafts, or shaft seals.
Economically and Environmentally Sound--The CenTraVacTM chiller has a proven track record as the world's most efficient, lowest emissions chiller. It is selectable at an unmatched efficiency level of 0.45 kW/ton at standard AHRI conditions. The full load efficiency levels of CenTraVacTM chillers are simply the best available, averaging at least 13.5 percent better than the next best centrifugal chiller available today.
Lowest Refrigerant Emissions--The key to the highest energy efficiency and lowest leak rate is use of the low pressure refrigerants. CenTraVacTM chillers are designed to be leak-tight, delivering the industry's lowest documented refrigerant leak rate--less than 0.5 percent annually versus the industry-accepted rate of 2.0 percent. We are so confident in our ability to keep the refrigerant inside our CenTraVacTM chillers, we back each one with a Leak-Tight Warranty--the first offered by any HVAC manufacturer.
EarthWiseTM System Design--This high-performance system design approach reduces first cost, lowers operating costs, and is substantially quieter than traditional applied systems. Central to the design are low flow, low temperature, and high efficiency for both airside and waterside systems, along with optimized control algorithms for sustainable performance. Tracer� AdaptiViewTM controls provide the system intelligence required to manage the performance and document the benefits. Smaller equipment and ductwork means supplying less airflow at colder temperatures and enables quieter operation. This also reduces relative humidity in the building, improving indoor air quality. Compared to conventional designs, an EarthWiseTM chilled water system reduces the total cost of ownership by lowering installation and operating costs.

General Information
Local Support
The performance and reliability of CenTraVacTM chillers is backed by a team of knowledgeable engineers, HVAC systems specialists, and technical professionals. Your local Trane team will see you through the entire chiller bid process, from building analysis to equipment specification and through installation and commissioning.
Custom Built Unit
Each CenTraVacTM chiller is custom built to meet your specific project requirements, optimizing the configuration based on design parameters such as full- and part-load performance and waterside pressure drops.
ISO 9001 Certified
The quality management system used by the Trane CenTraVacTM chiller manufacturing facility is the ISO 9001 Standard. This standard documents office, manufacturing, and testing procedures for maximum consistency in meeting or exceeding customer expectations. ISO 9001 requires extensive documentation on how quality assurance activities are managed, performed, and continuously monitored. Included in the system are verification checkpoints from the time the order is entered until final shipment. In addition, product development is subjected to formal planning, review, and validation.
Certified AHRI Performance
CenTraVacTM chillers are rated within the scope of the Air-Conditioning, Heating & Refrigeration Institute (AHRI) Certification Program and display the AHRI Certified� mark as a visual confirmation of conformance to the certification sections of AHRI Standard 550/590 (I-P) and ANSI/AHRI Standard 551/591 (SI). The purge is rated in accordance with AHRI Standard 580.
The applications in this catalog specifically excluded from the AHRI certification program are:
� Free cooling � Low temperature applications (below 36�F [2.2�C]), including ice storage � 60 Hz chillers larger than 3000 tons (10551 kW) and/or greater than 15000 volts � 50 Hz chillers larger than 3000 tons (10551 kW) and/or greater than 15000 volts � Heat recovery and heat pump ratings � Auxiliary condenser � Glycol and brines
District Cooling
Trane Adaptive ControlTM algorithms and the multi-stage design allow all CenTraVacTM chillers to deliver low leaving chilled water temperatures (e.g., 34�F [1.1�C]) without the use of glycol or other freeze inhibitors. This reduces the cost of delivering cooling capacity over long distances. Pre-engineered CenTraVacTM chiller thermal storage systems extend the chiller's exceptional reliability to the rest of the district cooling plant.
Turbine Inlet Cooling
Trane chillers are frequently used in conjunction with combustion turbines to increase the power capacity, efficiency, and life of the turbine. Turbine inlet cooling can eliminate the need for inlet water spray to reduce NOx emissions. With turbine inlet cooling, plants can delay or even avoid the need for additional turbines because more capacity can be obtained from existing turbines.

General Information
Elevated Chilled-Water Temperature Applications
The Series LTM CenTraVacTM chiller (model CVHL) is a direct result of the Trane commitment to provide the right technology for the right application at the right time.
Because industrial processes and data center applications have unique cooling requirements, the Series L chiller features optimized compressor and drive technology to deliver 60�F�70�F (15.6�C� 21.1�C) chilled water with up to 35 percent better efficiency at full-load and off-design conditions.
Premium Efficiency Chiller for Small Spaces
The Series STM CenTraVacTM chiller (models CVHM and CVHS) is an ideal solution for any lowtonnage application, especially retrofits and replacements. This compact chiller was designed to fit through standard double doors and features a bolt-together design for disassembly when access to the mechanical room is even tighter. While smaller in size, Series STM CenTraVacTM chillers continue to deliver the high efficiency, proven reliability, and ultra-quiet operation that Trane centrifugal chillers have provided for more than 75 years.

Next-Generation Refrigerants
Trane has always taken a balanced approach to selecting refrigerants, considering factors such as safety, sustainability, efficiency, reliability, and overall lifecycle impact. Expanding the CenTraVacTM chiller portfolio to operate with either R-123 or with one of two low pressure nextgeneration refrigerants (R-514A or R-1233zd) enables Trane to continue our commitment as the industry evolves through its next refrigerant transition, from HCFCs and HFCs to next-generation, low-GWP refrigerants.
Low pressure refrigerants have been a key element of the CenTraVacTM chiller design dating back to the very first Trane� centrifugal chiller in 1938. These new models continue the tradition offering a low pressure, leak-tight chiller that delivers best-in-class efficiencies.
CenTraVacTM chillers are available with either R-123, R-514A, or R-1233zd (CDHH and CVHH only). Classified as an "A1" refrigerant per ASHRAE Standard 34, R-1233zd is one of the few nonflammable olefin options available today. Likewise, R-514A is another next-generation refrigerant with a GWP of less than two.

General Information
Benefits of Low Pressure
Trane CenTraVacTM chillers feature a time-tested and proven low-pressure design utilizing environmentally friendly refrigerants, R-123, R-514A, and R-1233zd. They provide the safety of low pressure with continued product enhancements in leak-tight design. Consider the benefits of a low pressure CenTraVacTM chiller versus medium pressure machines:
Table 1. Operating pressure comparison at AHRI conditions
Evaporator
Low Pressure
Medium Pressure
� Always at negative pressure
� Operates at positive pressure
� Air leaks inward
� Refrigerant leaks outward at moderate rate
� Refrigerant lost: (# air leak in) x purge efficiency(a) � Refrigerant loss is difficult to know,
� No refrigerant loss into equipment room
performance is degraded
� Refrigerant loss is into equipment room
Condenser
� Usually at neutral to negative pressure during inactivity (air might leak inward)
� At slightly positive pressure during operation
� In the event of a leak, refrigerant could leak outward, but at a very low rate
� Always at high positive pressure
� In the event of a leak, refrigerant would leak outward at a very high rate
Monitoring of leak rate
� Unit purge is able to continuously monitor in leakage with the run meter, whether the chiller is on or off.
� Refrigerant monitor as required by ASHRAE.
� Purge can be connected to a building automation system for notification of increased purge operation (in-leak). Similarly, the BACnet� module allows the refrigerant monitor to be connected to the building automation system.
� Only ways to monitor leak rate on medium pressure chiller are:
� periodic leak checks
� purchase refrigerant monitor
� Refrigerant monitor as required by ASHRAE.
� Typically, the only time a leak is detected on a medium pressure chiller is during spring startup. This means that a chiller which develops a leak in the summer may leak continuously until the following spring.

The controller includes a unit-mounted control panel, the main processor, and an intuitive animated operator interface.
B. Unit Mounted Starters and Adaptive Frequency Drives--Trane offers a large selection of starters and drives. Trane starters offer standard features for safe, efficient application and ease of installation. Adaptive FrequencyTM drives are the industry's most capable variable speed drives, optimizing compressor speed control to reduce energy use.
C. Flash Economizer--CenTraVacTM chillers leverage a multi-stage design with two or three impellers, making it possible to flash refrigerant gas at intermediate pressure(s) between the evaporator and condenser. This feature increases chiller efficiency up to 4.5 percent for twostage chillers and up to 7 percent for three-stage chillers.
D. Refrigerant Cooled Motor--All Trane CenTraVacTM chiller motors are cooled by liquid refrigerant surrounding the motor winding and rotor. Using liquid refrigerant in uniform low temperatures prolongs motor life, as to open designs. As an additional benefit, motor heat is rejected out to the cooling tower, helping to keep the equipment room at a desirable temperature.
E. Low Pressure Design--Low pressure refrigerants have been a key element of the Trane centrifugal chiller design since 1938. Backed by the Trane 0.0% Leak Tight Warranty, the CenTraVacTM chiller's tight vessel low-pressure operation minimizes the chance for outward refrigerant leaks.
F. Purge System--The high efficiency purge system is designed with automatic regeneration capability. When the filter senses that it is full, the regeneration cycle begins, and reclaimed refrigerant is automatically returned to the chiller, keeping the purge's productivity at its peak without the need to exchange carbon canisters. The CenTraVacTM chiller purge system has capability to run even when the chiller is turned off.
G. Direct Drive Low�Speed Compressor--The exclusive CenTraVacTM compressor has only one moving part supported by just two bearings, providing reliability through simplicity of design. The low-speed, direct-drive design not only gives the CenTraVacTM compressor the most reliable and efficient operation, but also the lowest sound and vibration levels in the industry. This feature also eliminates the need for costly jacketing and energy-wasting liquid-refrigerant sound attenuation.

0.0% Leak-Tight Warranty
Terms and Conditions
The Company warrants for the lesser of 60 months from initial start-up or 66 months from date of shipment that the CenTraVacTM chiller will be leak-tight against refrigerant loss or the Company will furnish replacement refrigerant (the limited "Leak-Tight Warranty"). The limited Leak-Tight Warranty covers CenTraVacTM chillers (models CDHF, CDHH, CVHE, CVHF, CVHH, CVHL, CVHM, and CVHS) installed in the United States and Canada that ship from the factory in La Crosse, Wisconsin, September 1, 2004 or later. The Company's obligations and liabilities under this warranty are limited to furnishing replacement refrigerant; no other parts or labor are covered under this limited warranty. No liability whatever shall attach to the Company until appropriate actions (acceptable to Company) have been taken to eliminate the source of the leak.
If the chiller is placed under a comprehensive Trane service and maintenance agreement (Trane "Select Agreement" or better) prior to the expiration of the standard Leak-Tight Warranty, the protection against refrigerant loss shall continue under the Trane Select Agreement for as long as an active Trane Select Agreement remains in effect without interruption.
If a 10-Year Parts, Labor and Refrigerant Warranty was purchased for the chiller and the chiller is placed under the Trane Select Agreement (or better) prior to the expiration of the 10-Year Parts, Labor and Refrigerant Warranty, the protection against refrigerant loss shall continue under the Trane Select Agreement for as long as an active Trane Select Agreement remains in effect without interruption.
Any further warranty must be in writing, signed by an authorized representative of the Company.
NOTWITHSTANDING ANYTHING TO THE CONTRARY, IN NO EVENT SHALL THE COMPANY BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES EVEN IF A PARTY HAS BEEN ADVISED OF SUCH POSSIBLE DAMAGES OR IF SAME WERE REASONABLY FORESEEABLE AND REGARDLESS OF WHETHER THE CAUSE OF ACTION IS FRAMED IN CONTRACT, NEGLIGENCE, ANY OTHER TORT, WARRANTY, STRICT LIABILITY, OR PRODUCT LIABILITY.
Integrated Rapid Restart
Note: Restart times are based on chillers with a electromechanical speed starter. Restart times with a Trane Adaptive FrequencyTM Drive (AFD) will vary. Contact your local Trane account manager for more information.
A loss of cooling capacity can be costly, which is why CenTraVacTM chillers are designed to integrate seamlessly with uninterruptible power supplies (UPS) and have the shortest restart times in the industry.
In the event of a power interruption, the chiller defaults to its rapid restart mode, optimizing electrical and mechanical variables, including guide vane position. This not only helps the chiller get back online faster, but it also provides the least amount of load on your building's electrical infrastructure, which can make a big difference if your building has a backup generator.
Even under extreme conditions, CenTraVacTM chiller restart times have been verified at as few as 43 seconds, as shown in the following figure. Thanks to fast restart times like these, you can substantially minimize the risks of financially devastating damage to assets caused by overheating due to power outages. Of course, the truest test of a chiller's restart capabilities is the amount of time it takes to resume full-load cooling, and this is where the CenTraVacTM chiller really shines. An 80 percent cooling load can be achieved in less than three minutes after power restoration--your assurance that the cooling capacity your equipment requires is just a few minutes away.

Factory Performance Testing
CenTraVacTM chillers that fall within the scope of the AHRI Standard 550/590 (I-P) and ANSI/AHRI Standard 551/591 (SI) Certification Process bear the AHRI seal. All other CenTraVacTM chillers, and the selection software itself, are rated in accordance with the Standard. Performance testing is a key part of this program. Factory performance tests confirm that your chiller's actual performance matches what was predicted during the selection process, before the chiller is installed.
Standard AHRI tests are a well-recognized industry practice; however, a chiller's operating conditions vary significantly based on the needs of the building and its occupants. Data centers, hospitals, and retail locations all have specific requirements unique to their application and location. The Trane myTestTM program offers a fully customizable portfolio of chiller test packages and proof-of-performance options, in addition to standard AHRI tests. All tests and demonstrations are done in accordance with AHRI Standard 550/590, and the testing equipment is calibrated and validated by the National Institute of Standards Technology (NIST).
AHRI allows for standard tolerances in its certified selections; however, some customers may require tighter tolerances. Selecting and testing to zero tolerance requirements ensures that the full capacity and performance benefit are realized.

Conventional chillers use inlet guide vanes to provide stable operation at part-load conditions. Capacity is reduced by closing the vanes while maintaining a constant motor speed. A variable speed drive can be used to maximize chiller efficiency and reduce power consumption by adapting the compressor motor speed and inlet guide vanes to the chiller operating temperatures.
Wye (Star) Delta Starter
One of the most common starters in the industry is the wye (star)-delta. It is an air-cooled electromechanical starter initially set up in a "wye" or "star" configuration, which then transitions to a "delta" configuration during the starting sequence. In the wye configuration, the voltage applied to the motor windings is reduced, resulting in a reduction in the inrush current. The inrush current is 0.33 times the full voltage locked rotor current rating of the motor. The accelerating torque of the motor is also reduced to 33 percent of the full-voltage torque rating, which is sufficient to fully accelerate the compressor motor. During acceleration, when the line current drops to approximately 0.85 times rated load current, transition is initiated. With the completion of transition, the motor windings are connected in the delta configuration with full line voltage. This starter type can selected as either a unit- or remote-mounted option.
18
CTV-PRC007R-EN
Unit Options
Solid-State Starter
A solid-state starter controls the starting characteristics of a motor by controlling the voltage to the motor. It does so through the use of Silicon Controlled Rectifiers (SCRs) and an integral bypass contactor for power control. This starter type is offered as a unit-mounted or remote option.
Silicon Controlled Rectifiers An SCR will conduct current in one direction only when a control signal (gate signal) is applied. Because the solid-state starter is for use on alternating current (AC), two SCRs per phase are connected in parallel, opposing each other so that current may flow in both directions. For three phase loads, a full six-SCR configuration is used. During starting, control of current or acceleration time is achieved by gating the SCR on at different times within the half-cycle. The gate pulses are originally applied late in the half-cycle and then gradually applied sooner in the half-cycle. If the gate pulse is applied late in the cycle, only a small increment of the wave form is passed through, and the output is low. If the gate pulse is applied sooner in the cycle, a greater increment of the wave form is passed through, and the output is increased. So, by controlling the SCRs output voltage, the motor's acceleration characteristic and current inrush can be controlled.
Integral Bypass Contactors When the SCRs are fully "phased on," the integral bypass contactors are energized. The current flow is transferred from the power pole to the contactors. This reduces the energy loss associated with the power pole, which otherwise is about one watt per amp per phase. When the starter is given the stop command, the bypass contactors are de-energized, which transfers the current flow from the contactors back to the power poles. The SCRs are then turned off, and the current flow stops. Because the SCRs are turned off during normal operation, the design can be air-cooled and harmonic currents are not an issue.
Adaptive Frequency Drive
An Adaptive FrequencyTM Drive (AFD) may be used in lieu of a constant speed starter. Adaptive FrequencyTM is the trademarked term for a Trane� variable frequency drive (VFD) which is made to Trane specifications and uses proprietary control logic. The primary purpose of a VFD is to reduce energy consumption by changing the speed of the motor, but other benefits include improved power factor and soft starts. The combination of speed control and inlet guide vane (IGV) position is optimized mathematically and controlled simultaneously. The Adaptive ControlTM microprocessor controller allows the chiller to operate longer at higher efficiencies and with greater stability. The AFD regulates output voltage in proportion to output frequency to maintain ideal motor flux and constant torque-producing capability. It controls load-side frequency and voltage to adjust the compressor motor speed. The AFD is a voltage-source, pulse-width modulated (PWM) design. It consists of three primary power sections as shown in the following figure: the active rectifier, the DC bus, and the inverter.

Unit Options
Trane offers four low voltage options:
Unit-mounted refrigerant-cooled AFD with full harmonic attenuation--Available for use with 460/480V 60 Hz or 380�415V 50 Hz. This drive features an active rectifier to filter incoming AC power and convert it to a fixed DC voltage and meets the less than 5 percent total demand distortion (TDD) as standard, without the need for additional line-side filters to meet IEEE harmonic requirements.
Unit-mounted refrigerant-cooled AFD for CVHS/M--Operates the high-efficiency Permanent Magnet motor installed in all CVHS and CVHM chillers. The AFD includes an internal DC choke to provide TDD of approximately 30%, with the option to add an external passive harmonic filter to be IEEE-519 compliant. Available for use with 460V/480V 60Hz on CVHS, 460V/480V 60hz or 380� 415V 50/60Hz on CVHM.
Compact unit-mounted air-cooled AFD--This low profile AFD has a DC choke that minimizes harmonic distortion and results in a TDD of approximately 30 percent. Available for CVHE and CVHF models, 120 to 500 tons, 460/480V and 575/600V 60 Hz input power, �10 percent.
Remote (free-standing) air-cooled AFD--The remote AFD comes as a complete, free-standing package that includes the necessary controls, control power and programming needed for operation. Input voltage options include 460, 480, 575, and 600V. The remote AFD has as standard a 5 percent link reactor to help minimize harmonics, however it is a 6-pulse AFD which means the TDD is ~30 percent.

IEEE Standard 519 Harmonic Filter and Transformer Options
It is important to recognize that the IEEE Standard 519 as a guideline relates to the entire system, not specifically to any one load or product. IEEE Standard 519 establishes requirements at the point of common coupling (PCC) where the building connects to the utility system. The Standard contains no specific requirements for the internal electrical loads. Even though a Trane� AFDequipped chiller may attenuate its own harmonics, other non-linear loads on the same system may still create harmonic problems. In buildings where harmonics might be a concern, Trane
20
CTV-PRC007R-EN
Unit Options
recommends conducting a power-distribution system analysis to determine if there is a need to further attenuate harmonics at the system level.
Application of Drives on Chillers
Certain system characteristics favor installation of an AFD because of energy cost savings and shorter payback. These systems include:
� Condenser water temperature relief (colder than design temperatures) � Chilled-water reset � Utilities with high kWh and low kW demand rates
Condenser Water Temperature Relief or Chilled-Water Reset
Compressor lift reduction is required for a VFD chiller application, both to provide stable chiller operation and to achieve greater energy savings. A reduction in lift, also referred to as "relief," assumes colder entering condenser temperatures compared to the design entering temperature. Intelligent control to reduce condenser water temperature, or chilled-water reset strategies, are key to VFD savings in chiller system applications. Many believe that VFDs offer better efficiency at part load because part load values are often reported assuming condenser relief. A VFD can incrementally improve efficiency over a constant speed chiller at any load if you have substantial hours with reduced entering condenser water temperatures.
High Operating Hours with Relief
The following figure is based on an 800-ton (2800-kW) chiller at 42�F/55�F (5.6�C/12.8�C) in the evaporator, and 85�F (29.4�C) entering condenser water temperature, and 2.5 gpm/ton (0.045 L/ s�kW) of flow. Three lines are plotted (ECWT at 85�F [29.4�C], 75�F [23.9�C], and 65�F [18.3�C]); the y-axis is kW/ton and the x-axis is chiller percent load.
First, note the unloading curve with the 85�F (29.4�C) entering condenser water--this would be considered unloading with no relief. Then compare this curve with next two curves showing unloading with relief at 75�F (23.9�C) and 65�F (18.3�C), respectively. Note that efficiency improves significantly independent of the chiller load. This is why AFDs should be applied when there are significant hours of operation during which the condensing temperature is reduced.

High kW Demand Charges
Electric utility bills typically include both peak-based and consumption-based components. The demand or distribution charges are significant portions of the energy bill, even in deregulated markets. These charges are established by usage during utility peak hours, by individual peak usage, or a combination of peak and individual usage. This portion may or may not be influenced by installation of a VFD, because a VFD-equipped chiller draws more power at full load. If the peak chiller load coincides with utility peak hours, then the peak-based portion of the utility bill will increase. The energy or kWh portion will almost certainly be reduced because of the improved efficiency of the chiller plant during part-load and part-lift conditions throughout the year. The greater the kWh charge, and the smaller demand or distribution charges, the shorter the payback.

The AMPGARD� medium-voltage starter family by Eaton Cutler-Hammer�, built to Trane specifications, is available as a factory-installed option for use with CenTraVacTM chillers. Trane mounts, wires, and tests 2300�6600V unit-mounted starters (higher voltages are remote-mount only) at the factory, so you don't have to. This reduces, or eliminates altogether, the time, expense, and any added risk associated with having the starter installed and wired at the job site.
Medium-voltage starters have traditionally been freestanding due to their large size and weight. With advances in contactor technology and component layout, medium-voltage starters have become small enough to make unit-mounting feasible. When this is done, the starter becomes an integral part of the chiller, saving on equipment floor space.
Across-the-Line (Full Voltage)
An across-the-line starter is the smallest medium-voltage starter option. These starters draw the highest inrush current at starting line up (100 percent of locked roter amp or LRA), and have the shortest acceleration time (3-5 seconds).

Starter by Others
If the CenTraVacTM chiller starter will be provided by another manufacturer, the starter must be designed in accordance with the current Trane Starter by Others engineering specification. The system designer and installer are responsible for providing proper starting and control systems.
If another manufacturer's starter will be used with a CE-marked chiller (models CVHH and CDHH only), the system designer/engineer and installer are responsible for ensuring that both the starter and the wiring/connections between the starter and the chiller and the wiring connections into the starter itself meet all applicable CE/IEC standards including CE/IEC EMC standards.
Enhanced Electrical Protection Package Option
The Enhanced Electrical Protection Package is an option for both low and medium voltage CenTraVacTM chillers. Chillers with this option feature modified controls and electrical components to comply with more stringent industrial demands. The chiller construction meets the intent of NEMA 4 with completely enclosed wiring in seal-tight conduits and polycarbonate junction boxes. All warning markings and wire components have phenolic (permanent) labels. This option includes a control panel with screw-type control terminal-block connections. The purge is also upgraded to meet the intent of NEMA 4, including gasketed seal-tight conduits for electrical and control wiring, sealed motor terminal box, and a totally enclosed fan-cooled (TEFC) motor.
Note: The control panel, purge panel, junction boxes, terminal boxes, wiring/conduit and conduit connections do NOT have an environmental NEMA 4 rating on them. The chiller, itself, is still NEMA 1 rated and can only be used indoors. Even with the Enhanced Electrical Protection Package option, these units are not rated to be hosed down with water.
When the Enhanced Electrical Protection Package is selected, there are additional options available, which can be applied to remote-mounted medium-voltage starters, both from Trane and from other starter manufacturers.

Free Cooling Option
The Trane patented free cooling option for CenTraVacTM chillers adapts the basic chiller so it may function as a simple heat exchanger using refrigerant as the working fluid. A free cooling CenTraVacTM chiller can provide cooling without running the compressor, enabling significant energy and cost savings in many situations. For example, it may be possible to cool a building with a high cooling load located in a climate with cold winters exclusively with free cooling during three to six months of the year. In this case, the free cooling payback can easily be less than a year. Additionally, unlike a plate-and-frame heat exchanger solution, this factory-installed option requires no additional floor space or piping beyond the standard CenTraVacTM chiller.
The free cooling cycle is based on the principle that refrigerant migrates to the area of lowest pressure. When the condenser water is at a lower temperature than the chilled water, the refrigerant pressure will also be lower in the condenser than in the evaporator. This pressure difference causes refrigerant to boil in the evaporator and migrate to the condenser. The refrigerant returns to a liquid state in the condenser and flows by gravity back to the evaporator. This completes the refrigerant flow cycle, which can be repeated as long as a temperature/ pressure difference exists. The temperature differential between the evaporator and condenser determines the rate of refrigerant flow, and therefore, the cooling capacity delivered. The greater the temperature difference, the greater the cooling capacity--up to 45 percent of the nominal chiller capacity. When the free cooling cycle can no longer provide sufficient capacity to meet cooling requirements, mechanical cooling is restarted automatically by the unit control panel.

Benefits Application
CTV-PRC007R-EN
When condenser water is available at temperatures lower than the desired chilled water temperature, free cooling can provide up to 45 percent of nominal chiller capacity without operation of the compressor. Besides substantial energy cost savings, this Trane solution provides: � Single-Source Responsibility: Trane-engineered, -manufactured, and -installed. � Ease of Installation: Completely factory-installed and leak-tested, with factory-wired valves
and controls. � Ease of Operation: Changeover to/from free cooling automatically or by single switch control. � Reliability: Two simple valves are the only moving parts.
Modern buildings often require some form of year-round cooling to handle interior zones, solar loads, or computer loads. As the outside air temperature falls below the inside air temperature, it is often possible to use an outside air economizer to satisfy the cooling requirements. There are many situations, however, in which a free cooling CenTraVacTM chiller offers advantages over the use of an outside air economizer. It is possible for the free cooling chiller to satisfy the cooling load for many hours, days, or months during the fall, winter, or spring seasons without operation

of the compressor motor. This method of satisfying the cooling requirement can result in significant total energy savings over other types of systems. The savings available are most easily determined through the use of a computer energy analysis and economic program, such as TRACETM (Trane Air Conditioning Economics).
The suitability of free cooling for any particular installation depends upon a number of factors, including the temperature and quality of the outside air, the availability of cold condenser water, the type of airside system, the temperature and humidity control requirements, and the cost of electricity.
Temperature and quality of the outside air--In general, locations that have a substantial number of days with ambient temperatures below 45�F (7.2�C) wet bulb or more than 4000 degree days per year are well suited to free cooling operation. Additionally, a free cooling CenTraVacTM chiller may be a better solution than an outside air economizer in areas that have fouled air.
Availability of cold condenser water from a cooling tower, river, lake, or pond--A cooling tower must be winterized for offseason operation and the minimum sump temperature is limited by some cooling tower manufacturers. Cooling tower manufacturers should be consulted for recommendations on low temperature operation. With river, lake, or pond supply, condenser water temperatures down to freezing levels are possible.
Type of airside system--Airside systems like dual-duct, multi-zone and reheat systems which heat and cool the air can often effectively use a free cooling chiller. With an outside air economizer, as the outside temperature begins to fall, the cool outside air satisfies the cooling requirements. But, as the outdoor air temperature becomes very low, the outdoor air may need to be heated in order to maintain the design supply air temperature when it is mixed with return air. This "heating penalty" can be eliminated by using free cooling CenTraVacTM chiller. Warmer chilled water provided by the free cooling chiller would allow a warmer air temperature off the chilled-water coils, eliminating the heating energy required by an outside air economizer. With the high cost of electricity in most areas of the country, the heating penalty of an outside air economizer can be very significant.
Temperature and humidity control requirements--Low temperature outside air from an outside air economizer often requires a large amount of energy for humidification, which can often be reduced with a free cooling chiller. However, applications which require extremely precise humidity control typically cannot tolerate the warmer-than-design chilled-water temperatures delivered by a free cooling chiller. Likewise, free cooling is not used in conjunction with heat recovery systems, since mechanical cooling must be used to recover heat that will be used elsewhere in the building for simultaneous heating.
Free cooling operates on the principle that refrigerant flows to the area of lowest pressure in the system. The Chiller Plant Control (CPC) application in the Tracer� SC system controller can be used for automatic free cooling control. When condenser water is available at a temperature lower than the required leaving chilled-water temperature, the CPC starts the free cooling cycle. If the load cannot be satisfied with free cooling, the CPC or a customer-supplied system can automatically switch to the powered cooling mode. If desired, the chiller can be manually switched to the free cooling mode at the unit control panel. Upon changeover to free cooling, the liquid and gas line shutoff valves are opened and a lockout circuit prevents compressor energization. Liquid refrigerant drains from the storage tank (except models CDHH and CVHH) into the evaporator, flooding the tube bundle. Because of the water temperature difference, the refrigerant temperature and pressure are higher in the evaporator than in the condenser, so the refrigerant gas that boils off in the evaporator will flow to the condenser. The refrigerant then condenses and flows by gravity back to the evaporator. This free cooling cycle is sustained as long as a temperature difference exists between the condenser and evaporator water; it is this difference that determines the rate of refrigerant flow between the two shells and hence the free cooling capacity.
If the system load becomes greater than the free cooling capacity, free cooling operation is disabled--either manually by the operator; via a binary input from a customer-supplied system; or automatically by the CPC. The gas and liquid valves close and the compressor starts. Refrigerant gas is drawn out of the evaporator by the compressor, compressed, and introduced into the condenser. Most of the condensed liquid first takes the path of least resistance by
CTV-PRC007R-EN
Unit Options
flowing into the storage tank (except models CDHH and CVHH) which is vented to the high pressure economizer sump by a small bleed line. When the storage tank (except models CDHH and CVHH) is filled, liquid refrigerant must flow through the bleed line restriction. The pressure drop through the bleed line is greater than that associated with the orifice flow control device, hence liquid refrigerant flows normally from the condenser through the orifice system and into the economizer. The free cooling option consists of the following factory-installed or supplied components: � Additional refrigerant charge required for the free cooling cycle � Manual free cooling controls on the unit control panel � Refrigerant gas line with electrically actuated shutoff valve between the evaporator and
condenser � Refrigerant storage vessel adjacent to the economizer � Liquid line with electrically activated shutoff valve between the condenser sump and

Full Heat Recovery
A heat recovery CenTraVacTM chiller can significantly reduce energy costs by using heat which would normally be rejected to the atmosphere. This heat may be used for perimeter zone heating, reheat air conditioning systems, and preheating domestic hot water. Any building with a simultaneous heating and cooling load is a potential candidate.
Most heating applications require water warmer than the 85�F to 95�F (29.4�C to 35�C) typically sent to the cooling tower. Therefore, most heat recovery chillers are required to produce higher leaving condenser water temperatures, and thus will not achieve the energy efficiencies of standard, cooling-only chillers. The following figure illustrates the typical operating cycles of a cooling-only and a heat recovery chiller. The most noticeable differences are:
1. The pressure differential of the compressor is much greater for the heat recovery cycle.
2. The amount of heat rejected from the heat recovery condenser is greater than that which would be rejected in cooling-only operation.
3. There is a decrease in the refrigeration effect (RE). Higher condensing pressures increase the intermediate pressure in the economizer. Therefore, the liquid in the economizer has a higher enthalpy during the heat recovery mode than during standard chiller operation and the RE is slightly decreased. Because of this decreased RE, the compressor must pump more gas per ton of refrigeration.

Enthalpy Note: RE = Refrigeration Effect
The effect of this increased pressure differential and decreased refrigeration effect is a heat recovery machine which consumes more energy during heat recovery operation.
Typical catalog efficiencies for heat recovery machines operating in the heat recovery mode range from 0.64 to 0.84 kW/ton (5.49 to 4.18 COP) and range from 0.54 to 0.57 kW/ton (6.51 to 6.16 COP) for a cooling-only machine. Not only can there be an energy consumption penalty due to the inherent differences in operating cycles for heat recovery machines, but traditional chiller designs can add to that energy handicap. A heat recovery machine's operating efficiency is penalized year-round by having the capability to produce high heating water temperatures. Impellers are selected to produce the maximum refrigerant pressure difference between the evaporator and condenser, which is shown in Figure 9, p. 30. This means the impeller diameters are determined by the heat recovery operating conditions.
The CenTraVacTM chiller compressor and advanced impeller design reduce this costly energy penalty. The higher lift and stability of the multi-stage compressor enables a closer match of impeller size for both the cooling only and heat recovery operating conditions.

Simultaneous Heating and Cooling
The heat recovery CenTraVacTM chiller is an excellent choice for applications requiring simultaneous heating and cooling. These chillers save energy by recovering heat that would normally be rejected to the atmosphere and using it to provide space heating, hot water for the building, or process hot water.

This heat is provided at a fraction of conventional heating systems cost. A heat recovery CenTraVacTM chiller can provide 95�F to 105�F (35�C to 40.6�C) hot water depending upon the operating conditions. Two separate condenser shells are used with the heat recovery option for models CDHF, CVHE, and CVHF. The heating circuit and cooling tower circuit are separate, preventing cross contamination. Refrigerant gas from the compressor flows into both condense shells allowing heat rejection to one or both condenser water circuits.
The heat recovery option for model CVHH uses two separate bundles within the same condenser shell. Refrigerant gas from the compressor then flows into the single condenser shell allowing heat rejection to one or both condenser water circuits.
The reliability of the heat recovery CenTraVacTM chiller has been proven in installations around the world. This option is completely factory packaged.
Partial Heat Recovery
Models CDHF, CDHG, CVHE, CVHF, CVHG, and CVHH: All heat recovery systems require a simultaneous demand for heating and cooling. While a traditional (full) heat recovery system uses higher temperature water to satisfy a building heating load or the full heat input for domestic hot water, partial heat recovery with the auxiliary condenser option can be used for smaller heating demand, such as reheat air conditioning systems, swimming pools or to preheat domestic or boiler makeup water. Schools, hospitals, office buildings, and hotels have all proved to be excellent applications for the auxiliary condenser option.

Heating Water Temperatures and Control
To further reduce the system energy requirements, the following design considerations should be incorporated into any heat recovery system.
It is always desirable to use the lowest heating water temperature the application allows. Experience has shown that a design heating water temperature of 105�F to 110�F (40.6�C to 43.3� C) can satisfy most heating requirements. Lower temperatures increase the chiller operating efficiency in both the heating and cooling modes. In general, the heat recovery power consumption will increase 7 to 14 percent for every 10�F (5.6�C) increase in the design heating water temperature. Equally important is how that temperature is controlled. In most cases, the heating water temperature control should maintain the return heating water temperature. By allowing the supply water temperature to float, the mean water temperature in the system drops as the chiller load decreases and less heat is rejected to the condenser. As the mean heating water temperature drops, so does the refrigerant condensing temperature and pressure difference which the compressor is required to produce at part load. This increases the unloading range of the compressor.
When the supply heating water temperature to the building system is maintained and the return heating water temperature to the condenser is allowed to float, the mean heating water temperature actually rises as the chiller load decreases and less heat is rejected to the condenser. As the following figure illustrates, when the compressor unloads, the pressure difference that it must oppose to prevent surging remains essentially the same, while the compressor's ability to handle the pressure difference decreases. Therefore, the chiller's ability to unload without the use of hot gas bypass is reduced.

Hot gas bypass artificially increases the load on the compressor by diverting refrigerant gas from the condenser back to the compressor. Although hot gas bypass increases the unit's power consumption by forcing the compressor to pump more refrigerant gas, it will increase the heat available to recover for those applications where significant heating loads remain as the cooling load decreases.
Application
All heat recovery systems require a simultaneous demand for heating and cooling. While a traditional (full) heat recovery system uses higher temperature water to satisfy a building heating load or the full heat input for domestic hot water, partial heat recovery with the auxiliary condenser option can be used for smaller heating demand, such as reheat air conditioning systems, swimming pools or to preheat domestic or boiler makeup water. Schools, hospitals, office buildings, and hotels have all proved to be excellent applications for the auxiliary condenser option.
Increased Chiller Efficiency
The auxiliary condenser not only captures energy otherwise lost, it also increases chiller efficiency by increasing condenser heat transfer surface area and lowering the pressure differential the compressor must generate. This is because the auxiliary condenser water is always at a lower temperature than the standard condenser water.
Auxiliary condensers are available in standard and large. Because the auxiliary condenser is a separate condenser, there is no cross contamination between the cooling tower water and the heat recovery water circuits. No temperature controls are required and auxiliary condensers come factory-mounted.
Controls
The auxiliary condenser was designed for simplicity of operation. Machine load, water flow rate, and temperature determine the amount of heat recovered. There are no controls needed for heating water temperature because no attempt is made to maintain a specific hot water temperature in or out of the auxiliary condenser.
Operation
The auxiliary condenser is a factory-mounted, separate, shell and tube heat exchanger available on models CDHF, CDHG, CVHE, CVHF, CVHG, and CVHH CenTraVacTM chillers.
Because refrigerant gas always migrates to the area of lowest temperature, auxiliary condenser operation is simple. As the discharge gas leaves the compressor, it is free to flow to the auxiliary condenser or the standard condenser. Since water entering the auxiliary condenser is normally colder than that entering the standard condenser, the auxiliary condenser will have a lower bundle temperature and will attract the refrigerant gas. The auxiliary condenser will recover as much heat as the machine cooling load, heating water temperature, and flow rate will allow. All remaining heat will automatically be rejected through the standard condenser to the atmosphere
32
CTV-PRC007R-EN
System Options
through the cooling tower. No controls are needed to balance heat rejection in the two condensers.
Good system design will include a heated water bypass to ensure that water does not circulate through the auxiliary condenser when the chiller is de-energized. There are several ways to bypass the auxiliary condenser. When the hot water system is installed as shown, the bypass is automatic if the heating water pump is interlocked with the chiller compressor motor.
Another bypass arrangement is to install a diverting valve. When interlocked with the compressor motor, this valve diverts the heating water flow to the conventional heating system whenever the chiller is not operating. These are only examples of the many ways available to accomplish a bypass.

Thermal/Ice Storage
An ice storage system uses a dual-duty chiller to make ice at night when utilities charge less for electricity. The ice supplements or even replaces mechanical cooling during the day when utility rates are at their highest. This reduced need for cooling results in significant utility cost savings.
Another advantage of ice storage is standby cooling capacity. If the chiller is unable to operate, one or two days of ice may still be available to provide cooling. In that time, the chiller can be repaired before building occupants feel any loss of comfort.
The CenTraVacTM chiller is uniquely suited for low temperature applications, like ice storage, because it uses multiple stages of compression, versus competitive designs with only one stage. This allows the chiller to produce ice efficiently with less stress on the machine. The multi-stage compressor allows the lower suction temperatures required to produce ice and the higher chiller efficiencies attributed to centrifugal chillers. Trane� three-stage and two-stage centrifugal chillers produce ice by supplying ice storage vessels with a constant supply of 20�F to 25�F (-6.7� C to -3.9�C) glycol solution. CenTraVacTM chillers selected for these lower leaving fluid temperatures are also selected for efficient production of chilled fluid at normal comfort cooling conditions. The ability of Trane� chillers to serve "double duty" in ice production and comfort cooling greatly reduces the capital cost of ice storage systems.
A glycol solution is used to transfer heat from the ice storage tanks to the CenTraVacTM chiller and from the cooling coils to either the chiller or the ice storage tanks. The use of a freezeprotected solution eliminates the design time, field construction cost, large refrigerant charges, and leaks associated with ice plants. Ice is produced by circulating 20�F to 25�F (-6.7�C to -3.9�C) glycol solution through modular insulated ice storage tanks. Each tank contains a heat exchanger constructed of polyethylene tubing. Water in each tank is completely frozen with no need for agitation. The problems of ice bridging and air pumps are eliminated.
When cooling is required, ice chilled glycol solution is pumped from the ice storage tanks directly to the cooling coils. No expensive heat exchanger is required. The glycol loop is a sealed system, eliminating expensive annual chemical treatment costs. The centrifugal chiller is also available for comfort cooling duty at nominal cooling conditions and efficiencies. The modular concept of glycol ice storage systems and the proven simplicity of Trane Tracer� controls allow the successful blend of reliability and energy saving performance in any ice storage application.
The ice storage system operates in six different modes, each optimized for the utility cost of the hour:

Simple and smart control strategies are another advantage the CenTraVacTM chiller has for ice storage applications. Trane Tracer� building management systems can actually anticipate how much ice needs to be made at night and operate the system accordingly. The controls are integrated right into the chiller. Two wires and preprogrammed software dramatically reduce field installation cost and complex programming.
Tracer� optimization software controls operation of the required equipment and accessories to easily transition from one mode of operation to another. Even with ice storage systems, there are numerous hours when ice is neither produced or consumed, but saved. In this mode, the chiller is the sole source of cooling. To cool the building after all ice is produced, but before high electrical demand charges take effect, Tracer� controls set the CenTraVacTM chiller leaving fluid setpoint to the system's most efficient setting and start the chiller.
When electrical demand is high, the ice pump is started and the chiller is either demand-limited or shut down completely. Tracer controls have the intelligence to optimally balance the contribution of ice and chiller in meeting the cooling load.
The capacity of the chiller plant is extended by operating the chiller and ice in tandem. Tracer controls ration the ice, augmenting chiller capacity while reducing cooling costs.
When ice is produced, Tracer� controls will lower the CenTraVacTM chiller leaving fluid setpoint and start the chiller, ice pumps, and other accessories. Any incidental loads that persist while producing ice can be addressed by starting the load pump and drawing spent cooling fluid from the ice storage tanks.

Application and Job Site Considerations
Condenser Water Control
CenTraVacTM chillers start and operate over a wide range of load conditions with controlled water temperatures. Reducing the condenser water temperature is an effective way to lower the chiller power input; however, the effect of lowering the condenser water temperature may cause an increase in system power consumption. Although CenTraVacTM chillers can start and operate without control of the condenser water temperature, However, for optimum system power consumption, and for multiple-chiller applications, control of the condenser water circuit is recommended. integrated control of the chillers, pumps, and towers is easily accomplished with the chiller controller and/or Tracer� building controls.
Most chillers are designed for entering tower temperatures around 85�F (29.5�C), but CenTraVacTM chillers can operate at reduced lift down to a 3 psid (20.7 kPaD) pressure differential between the condenser and evaporator at any steady state load without oil loss, oil return, motor cooling, refrigerant hang-up, or purge problems. This can equate to safe minimum entering condenser water temperatures at or below 55�F (12.8�C) dependent on a variety of factors such as load, leaving evaporator temperature, and component combinations. Startup below this differential is possible as long as the 3 psid (20.7 kPaD) minimum pressure differential is achieved within a given amount of time. Refer to CTV-PRB006*-EN (Engineering Bulletin: Condenser Water Temperature Control for CenTraVac Centrifugal Chiller Systems with Tracer AdaptiView Controls) for additional information.
Water Treatment
The use of untreated or improperly treated water in a chiller may result in scaling, erosion, corrosion, algae, or slime. It is recommended that the services of a qualified water treatment specialist be used to determine what treatment, if any, is advisable. Trane assumes no responsibility for the results of untreated, or improperly treated water.
Water Pumps
Avoid specifying or using 60 Hz (3600 rpm) or 50 Hz (3000 rpm) condenser and chilled-water pumps. Such pumps may operate with objectionable noises and vibrations. In addition, a low frequency beat may occur due to the slight difference in operating rpm between water pumps and CenTraVacTM chiller motors. Where noise and vibration-free operation are important, Trane encourages the use of 60 Hz (1750 rpm) or 50 Hz (1500 rpm) pumps.
Water Flow
Today's technology challenges AHRI's traditional design of 3 gpm/ton (0.054 L/s�kW) through the condenser. Reduced condenser flows are a simple and effective way to reduce both first and operating costs for the entire chiller plant. This design strategy will require more effort from the chiller. But pump and tower savings will typically offset any penalty. This is especially true when the plant is partially loaded or condenser relief is available.
In new systems, the benefits can include dramatic savings associated with:
� Size and cost of the water pumps and cooling tower � Pump and cooling tower fan energy (30 to 35 percent reduction) � Size and cost for condenser lines and valves
Replacement chiller plants can reap even greater benefits from low flow condensers. Because the water lines and tower are already in place, reduced flows offer tremendous energy savings. Theoretically, a 2 gpm/ton (0.036 L/s�kW) design applied to a 3 gpm/ton (0.054 L/s�kW) system would offer a 70 percent reduction in pump energy. At the same time, the original tower would require a nozzle change but would then be able to produce about two degrees colder condenser water than before. These two benefits would typically offset any extra effort required by the chiller.

Key features and benefits of the Tracer� AdaptiViewTM chiller control are highlighted here with additional information available in CTV-PRB009*-EN (Engineering Bulletin: Tracer AdaptiView Control for EarthWise CenTraVac Chillers).
Control Panel and Operator Interface
The Tracer� AdaptiViewTM control panel is a 12 inch (30.5 centimeter) touchscreen display that provides an intuitive navigation system. This control panel allows the user to select from 27 different languages to ensure that the operator can easily see and understand how the chiller is operating.

Feed Forward Adaptive Control
Feed Forward Adaptive ControlTM is an open loop, predictive control strategy that uses the evaporator entering water temperature as an indicator of load change, allowing the controller to respond faster and to maintain stable leaving water temperatures. Feed Forward Adaptive ControlTM algorithms are patented control strategies that respond to both normal and extreme operating conditions to maintain effective chiller plant operation.

Variable-Primary Flow (VPF)
Chilled-water systems that vary the water flow through the chiller evaporator have caught the attention of engineers, contractors, building owners, and operators. Varying the water flow reduces the energy consumed by pumps, while having limited effect on the chiller energy consumption. This strategy can be a significant source of energy savings, depending on the application. As standard, the CenTraVacTM chiller can handle up to 30 percent change in flow per minute and stay online. Add the "," for even greater capacity control and the ability to display the evaporator and condenser flow rates on the control panel.
34�F (1.1�C) Leaving Water Temperature
Another benefit of Feed Forward Adaptive ControlTM is the ability to operate the CenTraVacTM chiller at low leaving evaporator water temperatures without the use of glycol. Colder water is generally used in wide delta-T systems, reducing the pumping energy required and making it less expensive to deliver cooling capacity over long distances. For this reason, low leaving water temperatures are frequently used in district cooling applications, but can also be used in comfort cooling applications. Your local Trane account manager can assist in making chiller two- or three-pass selections using 34�F to 36�F (1.1�C to 2.2�C) leaving water temperatures. Special installation procedures may be required.
Chilled-Water Reset
Chilled-water reset reduces chiller energy consumption during periods of the year when heating loads are high and cooling loads are reduced. It is based on return chilled-water temperature. Resetting the chilled-water temperature reduces the amount of work that the compressor must do by increasing the evaporator refrigerant pressure. This increased evaporator pressure reduces the pressure differential the compressor must generate while in the heat recovery mode. Chilledwater reset is also used in combination with the hot-water control. By resetting the chilled-water temperature upward, the compressor can generate a higher condenser pressure, resulting in higher leaving hot-water temperatures.

Hot-Water Control
In the hot-water mode, the chiller produces hot water as its primary objective, rather than chilled water--similar to the heat recovery operation. A leaving condenser water set point is maintained while the leaving evaporator temperature is allowed to modulate with the load. The hot-water mode is performed without a secondary condenser. As an option, the "Optional Extended Operation Package," p. 41 allows an external controller to enable, disable, and modulate this mode.

Controls
Ice-Making Control
For chillers that have been selected for ice-making operation, the standard control package includes the ice-making mode. As an option, the "Optional Extended Operation Package," p. 41 allows an external controller to enable, disable, and modulate this mode.
Optional Enhanced Flow Management Package
With the Enhanced Flow Management Package, the Tracer� AdaptiViewTM chiller controller reliably accommodates variable evaporator water flow and virtually eliminates its effect on the chilled water temperature. This option includes transducers for the differential evaporator and condenser water pressures. Flow switches or some other means to prove flow are still required and must be field connected. One type of sensor handles all pressure ranges up to 300 psig (2068.4 kPaG).
The Tracer� AdaptiViewTM chiller controller uses a patented, variable water-flow compensation algorithm to maintain stable, precise capacity control. If the water-pressure transducer fails and the flow switch continues to prove flow, water-flow compensation will be disabled and the design delta-T will be used. For applications designed to operate with variable-primary water flow, variable-flow compensation allows the chiller to respond quickly to changes in chilledwater flow rate. By automatically adjusting the control gain, large changes in the water-flow rate are accommodated. Figure 17, p. 40 demonstrates water-temperature control without flow compensation. In contrast, Figure 18, p. 40 demonstrates water-temperature control with flow compensation enabled. The chilled-water temperature remains stable, even when the water flow rate drops 50 percent in 30 seconds.
Another benefit is disturbance rejection. Figure 19, p. 41 shows the test results from step changes in water flow with increasing magnitudes. The leaving chilled-water temperature remains largely unaffected. Even the most severe change--dropping water flow 66 percent in 30 seconds--caused only a small, 1.5�F (0.83�C) variation in chilled-water temperature. While it is unlikely that a chiller application would make water flow changes of this magnitude, the results demonstrate that the chiller is more than capable of supporting variable water flow applications.
The following data will be shown on the Tracer� AdaptiViewTM control panel, the Tracer� TU display, and at the Tracer� controls:
� Evaporator capacity (tons, kW) � Evaporator and condenser flow rates (gpm, L/s) � Evaporator and condenser differential water pressures (psid, kPaD)
It will automatically adjust capacity control to:
� Minimize variable-flow disturbance � Maintain control stability at low flow

Optional Extended Operation Package
Select the extended-operation package for chillers that require external ice-building control, hot water control, and/or base-loading capabilities. This option includes the following: refrigerant monitor input, external base-loading binary input, external base-loading control, external icebuilding binary input, external ice-building control and external hot-water control binary input.
Base-Loading Control--This option allows an external controller to directly modulate the capacity of the chiller. It is typically used in applications where virtually infinite sources of evaporator load and condenser capacity are available and it is desirable to control the loading of the chiller. Two examples are industrial process applications and cogeneration plants.
Ice-Making Control--This option allows an external controller to control the chiller in an ice storage system. While the standard controller is fully capable of running the chiller in ice-making mode, installation savings and additional energy savings can be realized by using the Chiller Plant Control module of the Tracer� building automation system. Chiller Plant Control anticipates how much ice needs to be made at night and operates the system accordingly. The controls are integrated with the chiller--two wires and pre-programmed software reduce fieldinstallation cost and complex custom programming.
Hot-Water Control--This option allows an external controller to enable/disable and modulate the hot-water control mode. Occasionally, CenTraVacTM chillers are used to provide heating as a primary operation. In this case the external controller or operator would select a hot-water temperature set point and the chiller capacity would be modulated to maintain the set point. Heating is the primary function and cooling is a waste product or a secondary function. This technique provides application flexibility, especially in multiple-chiller plants in conjunction with undersized heating plants.
Refrigerant Monitor--This option allows for a refrigerant monitor to send a 4�20 mA signal to the Tracer� AdaptiViewTM control display. It can be calibrated to correspond to either 0�100 ppm or 0�1000 ppm concentration levels. The concentration level is displayed on the Tracer� AdaptiViewTM control panel, but the chiller will not take any action based on the input from the refrigerant monitor.
Alternatively, the BACnet� module allows the refrigerant monitor to be connected to Trane Tracer� controls, which have the ability to increase ventilation in the equipment room in response to high refrigerant concentrations.

Communications Interfaces
LonTalk Communications Interface (LCI-C)
The optional LonTalk� Communications Interface for Chillers (LCI-C) is available factory or field installed. It is an integrated communication board that enables the chiller controller to communicate over a LonTalk� network. The LCI-C is capable of controlling and monitoring chiller setpoints, operating modes, alarms, and status. The Trane LCI-C provides additional points beyond the standard LonMark� defined chiller profile to extend interoperability and support a broader range of system applications. These added points are referred to as open extensions. The LCI-C is certified to the LonMark� Chiller Controller Functional Profile 8040 version 1.0, and follows LonTalk� FTT-10A free topology communications.
Native BACnet Communications
Tracer� AdaptiViewTM control can be configured for BACnet� communications at the factory or in the field. This enables the chiller controller to communicate on a BACnet� MS/TP network. Chiller setpoints, operating modes, alarms, and status can be monitored and controlled through BACnet�.
Tracer� AdaptiViewTM controls conform to the BACnet� B-ASC profile as defined by ANSI/ ASHRAE Standard 135-2004.
Modbus Communications
Tracer� AdaptiViewTM controls can be configured for Modbus� communications at the factory or in the field. This enables the chiller controller to communicate as a slave device on a Modbus� network. Chiller setpoints, operating modes, alarms, and status can be monitored and controlled by a Modbus� master device.
Tracer TU Interface
The Tracer� chiller controller adds a level of sophistication better served by a PC application to improve service technician effectiveness and minimize chiller downtime. The Tracer� AdaptiViewTM control's operator interface is intended to serve only typical daily tasks. The portable PC-based service-tool software, Tracer� TU, supports service and maintenance tasks.
Tracer� TU serves as a common interface to all UC800 and BCI-C (BACnet�) based Trane� chillers, and will customize itself based on the properties of the chiller with which it is communicating. Thus, the service technician learns only one service interface.
The panel bus is easy to troubleshoot using LED sensor verification. Only the defective device is replaced. Tracer� TU can communicate with individual devices or groups of devices.
All chiller status, machine configuration settings, customizable limits, and up to 100 active or historic diagnostics are displayed through the service-tool software interface.
LEDs and their respective Tracer� TU indicators visually confirm the availability of each connected sensor, relay, and actuator.
Tracer� TU is designed to run on a customer's laptop, connected to the Tracer� AdaptiViewTM control panel with a USB cable.
Laptop requirements for Tracer� TU:
� 1 GB RAM (minimum) � 1024 x 768 screen resolution � CD-ROM drive � Ethernet 10/100 LAN card � An available USB 2.0 port � Microsoft� Windows� operating system: Windows� 7 Enterprise, Windows� 8 Enterprise,

Building Automation and Chiller Plant Control
System and Chiller Plant Controls
Tracer� SC allows you to streamline facility management without reinventing the entire system. Adding Tracer� SC to your system provides a flexible, cost effective solution for building automation and climate control that can extend to lighting and energy consumption. Accessible from a personal computer, tablet or smart phone, Tracer� SC eliminates the need for a dedicated computer so you can manage system performance whenever and wherever it is convenient. Tracer� SC is a simplified, web-based management tool that reduces scheduling, reporting and system application chores to simple "point and click" tasks. Tracer� SC strikes the perfect balance between tenant comfort and energy efficiency, resulting in operating cost savings and a better bottom line.
Note: Tracer SC can be factory installed as an option in the Agility Control Panel.
Area Application
The Area application coordinates groups of equipment based on tenant or occupant organization within a building, allowing for standard calculations and functions. The Area application can be configured to use multiple algorithms, along with area temperatures and humidity inputs, to make an economizing decision. Users are presented with a simplified, logical user interface with logical areas rather than directly interfacing with equipment. The Area application also supports:
� Optimal start/stop � Humidity pulldown � Night purge � Unoccupied heating/cooling setpoints � Unoccupied humidify/dehumidify � Timed override functions
For more information, refer to BAS-APG007*-EN (Applications Guide: Air Systems [including EarthWise Systems] for the Tracer SC System Controller).
Chiller Plant Control (CPC)
The Chiller Plant Control (CPC) application permits users to configure a chiller plant for optimal efficiency and reliability, while providing a means for monitoring and controlling the daily operation. Depending upon the chiller plant configuration and design, the CPC application can do the following:
� Provide overall chiller plant status information and alarms to local and remote Tracer� SC users
� Enable or disable chiller plants � Start, stop, and monitor the status of system chilled water pumps � Calculate individual chilled water setpoints for chillers in series chiller plants � Request when chillers are added or subtracted according to building load requirements and
user-specified add and subtract logic � Rotate chillers according to user-defined intervals � Remove chillers from the rotation in the event
For more information, refer to BAS-APG012*-EN (Applications Guide: Tracer SC System Controller Chiller Plant Control Application).
Chiller-Tower Optimization
The Tracer� chiller-tower optimization extends Adaptive ControlTM to the rest of the chiller plant. Chiller-tower optimization is a unique control algorithm for managing the chiller and cooling tower subsystem. It considers the chiller load and real-time ambient conditions, then optimizes the tower setpoint temperature to maximize the efficiency of the entire subsystem. This real-time optimization may vary tower temperatures between 50�F�90�F (10�C�32.2�C) depending upon current outdoor conditions, chiller loading, and ancillary efficiencies.

Tracer Building Controls
The Tracer� AdaptiViewTM chiller controller is designed to communicate with a wide range of building automation systems. To leverage all of your CenTraVacTM chiller capabilities, integrate your chiller into a Tracer� SC system controller or a comprehensive Tracer� ES building management system.
The Tracer� SC system controller can manage multiple systems within a building. It provides a flexible solution for managing your building's HVAC system, with an intuitive, web-based user interface and industry-leading 3D graphics and pre-programmed features such as:
� Chiller plant management--Allows you to manage multiple chillers of any size and coordinate with other equipment as part of your chiller plant operation for even greater energy efficiency and reduced operating costs.
� EarthWiseTM Systems--Apply integrated pre-packaged design concepts that are optimized for energy and environmental performance; sustainable systems that deliver measurable, repeatable and superior performance with lower operating costs.
The Tracer� ES building management software provides a web-based, scalable, integration platform for managing all of your facilities as a single enterprise. It allows you to view status and manage alarms and schedules from one system--from anywhere, and its reports enable enterprise-wide decision making for optimized performance. It also offers easy integration with other systems via BACnet� IP.
Standard Protections
The Tracer� AdaptiViewTM controller uses proportional-integral-derivative (PID) control for all limits--there is no dead band. This removes oscillation above and below setpoints and extends the capabilities of the chiller. Some of the standard protection features of the chiller controller are described in this section.
For a complete listing of CenTraVacTM motor protection capabilities, refer to CTV-PRB004*-EN (Engineering Bulletin: Frequency Drives, Starters, and Electrical Components for CenTraVac Chillers). For a complete listing of the Tracer� AdaptiViewTM chiller protection capabilities, refer to CTV-SVD03*-EN (Diagnostics Manual: Diagnostic Descriptions, Troubleshooting Tables, and Control Component Overview for Water-cooled CenTraVac Chillers with Tracer AdaptiView Control). Contact your local Trane sales office with any questions or for more information.
High Condenser-Pressure Protection
The chiller will protect itself from a starter failure that prevents disconnecting the compressor motor from the incoming line power.
The chiller controller's condenser limit keeps the condenser pressure under a specified maximum pressure. The chiller will run up to 100 percent of this setpoint before the Adaptive ControlTM mode reduces capacity.
Starter-Contactor Failure Protection
The chiller will protect itself from a starter failure that prevents the compressor motor from disconnecting from the line to the limits of its capabilities.
The controller starts and stops the chiller through the starter. If the starter malfunctions and does not disconnect the compressor motor from the line when requested, the controller will recognize the fault and attempt to protect the chiller by operating the evaporator and condenser water pumps, oil/refrigerant pumps and attempting to unload the compressor.
Loss of Water-Flow Protection
Tracer� AdaptiViewTM control has an input that will accept a contact closure from a proof-of-flow device such as a flow switch or pressure switch. Customer wiring diagrams also suggest that the flow switch be wired in series with the cooling-water and condenser-water pump starter auxiliary contacts. When this input does not prove flow within a fixed time during the transition from Stop to Auto modes of the chiller, or if the flow is lost while the chiller is in the Auto mode of operation, the chiller will be inhibited from running by a diagnostic.
44
CTV-PRC007R-EN
Controls
Evaporator Limit Protection
Evaporator Limit is a control algorithm that prevents the chiller from tripping on its low refrigerant-temperature cutout. The machine may run down to the limit but not trip. Under these conditions the intended chilled-water setpoint may not be met, but the chiller will do as much as it can. The chiller will deliver as much cold water as possible even under adverse conditions.
Low Evaporator-Water Temperature
Low evaporator-water temperature protection, also known as Freeze Stat protection, avoids water freezing in the evaporator by immediately shutting down the chiller and attempting to operate the chilled-water pump. This protection is somewhat redundant with the Evaporator Limit protection, and prevents freezing in the event of extreme errors in the evaporatorrefrigerant temperature sensor.
The cutout setting should be based on the percentage of antifreeze used in the customer's water loop. The chiller's operation and maintenance documentation provides the necessary information for percent antifreeze and suggests leaving-water temperature-cutout settings for a given chilled-water temperature setpoint.
High Vacuum-Lockout Protection
The controller inhibits a compressor start with a latching diagnostic whenever the evaporator pressure is less than or equal to 3.1 psia (21.4 kPaA). This protects the motor by locking out chiller operation while the unit is in a high vacuum--preventing startup without a refrigerant change during commissioning.
Oil-Temperature Protection
Low oil-temperature trips when the oil pump and/or compressor are running may be an indication of refrigerant diluting the oil (except for model CVHS chillers, which are oil-free). If the oil temperature is at or below the low oil-temperature setpoint, the compressor is shut down on a latching diagnostic and cannot be started. The diagnostic is reported at the user interface. The oil heater is energized in an attempt to raise the oil temperature above the low oil-temperature setpoint.
High oil-temperature protection is used to avoid overheating the oil and the bearings.
Low Differential Oil-Pressure Protection
Oil pressure is indicative of oil flow and active oil-pump operation (except for model CVHS chillers, which are oil-free). A significant drop in oil pressure indicates a failure of the oil pump, oil leakage, or a blockage in the oil circuit.
During compressor prelube the differential pressure should not fall below 12 psid (82.7 kPaD). A shutdown diagnostic will occur within 2 seconds of the differential pressure falling below twothirds (CDHF, CDHG, CVHE, CVHF, CVHG, CVHL, and CVHM) or three-quarters (CDHH and CVHH) of the low differential oil-pressure cutout.
When the compressor is running the shutdown diagnostic will occur when the differential pressure falls below the differential oil-pressure cutout for more than (cutout x 3) seconds. This allows for a relatively high cutout to be violated longer before triggering shutdown, as compared to a low cutout.
Excessive Purge Detection
Pump-out activity indicates the amount of air leaking into the chiller refrigerant system. The operator is informed when the air-leakage rate changes. The operator can specify an expected leakage rate, and can be notified through a diagnostic if the rate is higher than expected.
Occasionally, when a service technician performs a mechanical repair on the chiller, an unusually high pump-out rate is expected for a certain period of time following the procedure. The service excessive pump-out override allows the technician to specify a time period for the purge system to rid the chiller of air in the system. This temporarily suspends excessive purge detection.
CTV-PRC007R-EN

Controls
Phase-Unbalance Protection
Phase-unbalance protection is based on an average of the three-phase current inputs. The ultimate phase-unbalance trip point is 30 percent. In addition, the RLA of the motor is derated by resetting the active current limit setpoint based on the current unbalance. The RLA derate protection can be disabled in the field-startup menu.
The following derates apply when the phase-unbalance limit is enabled.
For CDHF, CDHG, CVHE, CVHF, CVHG, CVHL, CVHM, and CVHS:
10% unbalance = 100% RLA available 15% unbalance = 90% RLA available 20% unbalance = 85% RLA available 25% unbalance = 80% RLA available 30% unbalance = Shutdown
For CDHH and CVHH:
Less than 20% unbalance = 100% RLA available 20% unbalance = 80% RLA available 25% unbalance = 86% RLA available 30% unbalance = Shutdown
Phase-Loss Protection
The controller will shut down the chiller if any of the three-phase currents feeding the motor drop below 10 percent RLA. The shutdown will result in a latching phase-loss diagnostic. The time to trip is 1 second at minimum, 3 seconds maximum.
Phase Reversal/Rotation Protection
The controller detects reverse-phase rotation and provides a latching diagnostic when it is detected. The time to trip is 0.7 seconds.
Momentary Power Loss and Distribution Fault Protection
Three-phase momentary power loss (MPL) detection gives the chiller improved performance through many different power anomalies. MPLs of 2.5 cycles or longer will be detected and cause the unit to shut down. The unit will be disconnected from the line within 6 line cycles of detection. If enabled, MPL protection will be active any time the compressor is running. MPL is not active on reduced-voltage starters during startup to avoid nuisance trips. The MPL diagnostic is an automatic reset diagnostic.
An MPL has occurred when the motor no longer consumes power. An MPL may be caused by any drop or sag in the voltage that results in a change in the direction of power flow. Different operating conditions, motor loads, motor size, inlet guide vane position, etc., may result in different levels at which this may occur. It is difficult to define an exact voltage sag or voltage level at which a particular motor will no longer consume power, but we are able to make some general statements concerning MPL protection:
The chiller will remain running under the following conditions:
� Second-order or lower harmonic content on the line � Control-voltage sags of any magnitude less than 3 line cycles � Control-voltage sags of 40 percent or less for any amount of time � Line-voltage sag of 1.5 line cycles or less for any voltage magnitude sag
The chiller may shut down under the following conditions:
� Line-voltage sags of 1.5 or more line cycles for voltage dips of 30 percent or more � Third-order or higher harmonic content on the line � Control-voltage sags of three or more line cycles for voltage dips of 40 percent or more
Current-Overload Protection
The control panel will monitor the current drawn by each line of the motor and shut the chiller off when the highest of the three line currents exceeds the trip curve. A manual reset diagnostic describing the failure will be displayed. The current overload protection does not prohibit the
46
CTV-PRC007R-EN
Controls
chiller from reaching its full-load amperage. The chiller protects itself from damage due to current overload during starting and running modes, but is allowed to reach full-load amps.
High Motor-Winding Temperature Protection
This function monitors the motor temperature and terminates chiller operation when the temperature is excessive. The controller monitors each of the three winding-temperature sensors any time the controller is powered up, and displays each temperature at the service menu. The controller will generate a latching diagnostic if the winding temperature exceeds 265�F (129.4�C) for 0.5�2 seconds.
Surge Detection Protection
Surge detection is based on current fluctuations in one of three phases. The default detection criterion is two occurrences of root-mean square (RMS) current change of 30 percent within 0.8 seconds in 60 seconds �10 percent. The detection criterion is adjustable with the Tracer� chiller controller.
Overvoltage and Undervoltage Protection
While some components of the chiller are impervious to dramatically different voltages, the compressor-motor is not. The control panel monitors all three line-to-line voltages for the chiller, and bases the over and undervoltage diagnostics on the average of the three voltages. The default protection resets the unit if the line voltage is �10 percent of nominal for 60 seconds.
Power Factor and Kilowatt Measurement
Three-phase measurement of kilowatts (kW) and unadjusted power factor yields higher accuracy during power imbalance conditions.
Short-Cycling Protection
This function mimics heat dissipation from a motor start using two setpoints: Restart Inhibit Free Starts and Restart Inhibit Start-to-Start Timer. This allows the CenTraVacTM chiller to inhibit too many starts in a defined amount of time while still allowing for fast restarts. The default for CenTraVacTM chillers is three Free Starts and a 20 minute Start-to-Start Timer. The control panel generates a warning when the chiller is inhibited from starting by this protection.
Restart Inhibit Free Starts: This setting will allow a maximum number of rapid restarts equal to its value. If the number of free starts is set to 1, this will allow only one start within the time period set by the Start-to-Start Time setting. The next start will be allowed only after the start-tostart timer has expired. If the number of free starts is programmed to 3, the control will allow three starts in rapid succession, but thereafter, it would hold off on a compressor start until the Start-to-Start timer expired.
Restart Inhibit Start-to-Start Time Setting: This setting defines the shortest chiller cycle period possible after the free starts have been used. If the number of free starts is programmed to 1, and the Start-to-Start Time setting is programmed to 10 minutes, the compressor will be allowed one start every 10 minutes. The start-to-start time is the time from when the motor was directed to energize to when the next prestart is issued.
Enhanced Protection Option
This optional package includes sensors and transducers that enable the following protection features:
Enhanced Condenser-Limit Control
Includes factory-installed condenser-pressure transducer and all necessary interconnecting piping and wiring. Enhanced condenser-limit control provides high-pressure cutout avoidance by energizing a relay to initiate head relief.
Note: This option is in addition to the standard high refrigerant-pressure safety contact.

Optional Compressor-Discharge Refrigerant-Temperature Protection
Includes a factory-installed sensor and safety cutout on high compressor discharge temperature. Allows the chiller controller to monitor compressor discharge temperature, which is displayed at Tracer� AdaptiViewTM control and operator interface, Tracer� TU, and Tracer� building controls.
Note: When the chiller is selected with hot gas bypass, this sensor and its associated protections are included as standard.
Sensing of Leaving Oil Set Temperature For Each Bearing
Optional factory-installed sensors allow high-temperature safety cutouts to monitor the leaving bearing-oil temperatures (except for model CVHS chillers, which are oil-free). The chiller controller, Tracer� ES, and Tracer� SC display these temperatures. The compressor thrust bearing on models CDHH and CVHH chillers has three resistance temperature detectors (RTDs) that measure the bearing pad temperature during operation. The high bearing-temperature cutout is fixed at 180�F (82.2�C). If either bearing temperature violates the cutout, a latching diagnostic will be generated.

Chiller Selection
Fully Customizable Chiller Selection
The CenTraVacTM chiller product line provides more than 200,000 individual unit selections over a capacity range of 120 through 4000+ cooling tons (420 through 14000+ kW). Chiller selections and performance data can be obtained through the use of the CenTraVacTM chiller selection program available in local Trane sales offices. This program can provide AHRI-certified chiller selections optimized to match specific project requirements.
Performance
Trane Official Product Selection System (TOPSSTM) software provides performance data for each chiller selection at the full-load design point and part-load operating points as required.
Changing the number of water passes or water flow rates may significantly alter the performance of a particular chiller. To obtain the maximum benefit from the wide range of selections available, designers are encouraged to develop performance specifications and use the computer selection program to optimize their selections. This will allow the selection of the particular compressor-evaporator-condenser combination that most closely meets the job requirements. All selections are made using the TOPSSTM selection program.
The TOPSSTM selection program is certified by AHRI in accordance with AHRI Standards 550/590 (I-P) and 551/591 (SI). To ensure that the specific chiller built for your project will meet the required performance, and to ensure a more trouble-free startup, it is recommended that the chiller be performance tested on an AHRI-approved factory test loop.
The TOPSSTM selection program has the flexibility to select chillers for excessive field fouling allowances.

All heat exchanger tubes are subject to a certain amount of fouling during operation due to contaminants in the water and based on water treatment at the facility. Fouling impedes heat transfer and makes the chiller work harder.
AHRI Standards 550/590 (I-P) and 551/591 (SI) include a definition of the standard fouling factors to be used in water-cooled chiller ratings. The standard fouling adjustment is a 0.0001 increment from 0.0000 ("clean") on the evaporator and 0.00025 increment from 0.0000 ("clean") on the condenser.
Chiller specifications should be developed using the most current standard fouling factors.
Unit Performance with Fluid Media Other Than Water
CenTraVacTM chillers can be selected with a wide variety of media other than water. Typically used media include ethylene glycol or propylene glycol either in the evaporator, condenser, or both. Chillers using media other than water are excluded from the AHRI Certification Program, but are rated in accordance with AHRI Standard 550/590. Trane� factory performance tests are only performed with water as the cooling and heat rejection media. For fluid media other than water, contact your local Trane account manager for chiller selections and information regarding factory performance testing.
Flow Rate Limits
Flow rate limits for multiple pass combinations for evaporators and condensers are tabulated in the data section for the appropriate chiller family. For applications outside of these limits, please contact your local Trane account manager.
Roughing-in Dimensions
Dimensional drawings illustrate overall measurements of the chiller. The recommended space envelope indicates clearances required to easily service the CenTraVacTM chiller. A view of the unit with its support feet is superimposed on this drawing.

Chiller Selection
All catalog dimensional drawings are subject to change. Refer to the current submittal drawings for detailed dimensional information. If the unit must be disassembled in the field, refer to the Installation Guide: Disassembly and Reassembly Units for your specific model chiller (CVHESVN04*-EN for models CDHF, CDHG, CVHE, CVHF, and CVHG; CVHH-SVN001*-EN for models CDHH and CVHH; CVHM-SVN001*-EN for model CVHM; CVHS-SVN04*-EN for model CVHS) for detailed information. Contact your local Trane account manager for submittal and template information.
Evaporator and Condenser Data Tables
Evaporator and condenser data is shown in "Performance Data," p. 52 (Imperial [I-P] Units) and "Performance Data," p. 75 (International System [SI] Units). It includes minimum and maximum water flow limits and water connection sizes for all standard pass configurations and tube types. Pressure drops are calculated by the chiller computer selection program.
Full-Load and Part-Load Performance
The CenTraVacTM chiller possesses excellent performance characteristics over its full range of operation due to multi-stage, direct drive compressor that enables stable and efficient operation over a wide range of conditions, virtually eliminating the need for the energy-wasting hot gas bypass typically found on single-stage chillers. Reference Topps for your specific order selection for unit specific part load performance as selected. Always run selections at any expected off design conditions to verify proper expectations. .
In order to evaluate total energy costs over a period of time, an in-depth examination of projectspecific conditions and energy rate structures should be performed. Trane Air Conditioning Economics, or TRACETM, is a software program that helps HVAC professionals perform this type of analysis and optimize the design of a building's heating, ventilating and air conditioning system based on energy utilization and life-cycle cost. Visit www.traneCDS.com for more information.
Local utilities may offer substantial monetary rebates for centrifugal chillers with specific efficiency ratings. Contact your local utility or your local Trane account manager for further information.
The electrical rate structure is a key component of an economic evaluation. Most power bills include a significant demand charge in addition to the usage charge. The full-load power consumption of the chiller plant is likely to set the kW peak and demand charge for the billing period. This places an increased emphasis on the need to minimize the full-load power consumption of the chiller plant.
There are a number of variables that should be considered when developing a chiller load profile to compare part load performance of one chiller versus another. The use of outdoor air economizers, variations in chiller sequencing, and chiller plant load optimization strategies should be considered. Decoupled, primary/secondary water loops or variable-primary flow designs are more efficient ways to control multiple chiller water plants. These control strategies result in one chiller operating at a more fully loaded condition rather than multiple chillers operating at part load, which would require more pumping energy.
AHRI Standard 550/590 defines the entering condenser water temperatures for loads of 100, 75, 50, and 25 percent. Each point is tested, and then the Integrated Part Load Value (IPLV) can be calculated. Although some manufacturers focus on IPLV only, chiller efficiency is measured at

full load and part load operation. High efficiency at full load determines the capability of the chiller to minimize the electrical infrastructure required, and reduces the impact of demandbased charges and real-time pricing during peak periods. The full load efficiency rating is required for buildings to comply with most local codes. Both full load and IPLV ratings are required for LEED� Energy and Atmosphere (EA) credits.
myPLV Chiller Performance Evaluation Tool
The myPLVTM tool provides a simpler tool than TRACE provides for quick and reliable chiller economic comparisons considering both full and part load ratings.
The manufacturer-agnostic tool leverages industry-standard building model data, calculating four performance points (94, 75, 50 and 25 percent) based on the specific building type, location and plant design, providing accurate weighting points and condenser temperatures. The myPLVTM tool also calculates the ton-hours at each of those points necessary to accurately estimate annualized energy use.
Utilizing the myPLVTM tool from the beginning assures that the selected chiller is appropriate for the particular application. Then, myTestTM certification confirms the chiller performs as expected.

Note: The minimum evaporator water velocity is 1.5 ft/s for IECU tubes and 2.0 ft/s for all other tubes. For a variable evaporator water flow system, the minimum GPME is generally not applicable at full load, and may be limited by other factors such as glycol. Confirm actual minimum and maximum flows for each selection before operating near flow boundaries. Values in this table are based on 0.025-in. wall tubes for M, L, S, and E bundles and 0.028-in. wall tubes for D, M, and X bundles.

Weights (lb)
Important: The weight information provided here should be used for general information only. Trane does not recommend using this weight information for considerations relative to chiller handling, rigging, or placement. The large number of variances between chiller selections drives variances in chiller weights that are not recognized in these tables. For specific weights for your chiller, refer to your submittal package.

Note: The minimum evaporator water velocity is 0.457 m/s for IECU tubes and 0.610 m/s for all other tubes. For a variable evaporator water flow system, the minimum GPME is generally not applicable at full load, and may be limited by other factors such as glycol. Confirm actual minimum and maximum flows for each selection before operating near flow boundaries. Values in this table are based on 0.64-mm wall tubes for M, L, S, and E bundles and 0.71-mm wall tubes for D, M, and X bundles.

Weights (kg)
Important: The weight information provided here should be used for general information only. Trane does not recommend using this weight information for considerations relative to chiller handling, rigging, or placement. The large number of variances between chiller selections drives variances in chiller weights that are not recognized in these tables. For specific weights for your chiller, refer to your submittal package.

Mechanical Specifications
Compressor
Inlet Guide Vanes
Fully modulating variable inlet guide vanes provide capacity control. The guide vanes are controlled by an externally-mounted electric vane operator in response to refrigeration load on the evaporator.
Impellers
Fully shrouded impellers made of high strength aluminum alloy are directly connected to the motor rotor shaft operating at 3600 rpm (60 Hz) or 3000 rpm (50 Hz). The impellers are dynamically balanced and over-speed tested at 4500 rpm (60 Hz) and 3750 (50 Hz). The motorcompressor assembly is balanced to a maximum vibration of 0.15 in./s (3.8 mm/s) at 3600 rpm (60 Hz) or 3000 rpm (50 Hz) as measured on the motor housing.
Compressor Casing
Separate volute casings of refrigerant-tight, close-grained cast iron are used on the centrifugal compressor; each incorporating a parallel wall diffuser surrounded by a collection scroll. The diffuser passages are machined to ensure high efficiency. All casings are proof- and leak-tested.
Motor
Compressor motors are hermetically sealed two-pole, squirrel cage induction-type (except for models CVHM and CVHS chillers, which use a permanent magnet motor--a specially designed, eight-pole motor suitable for unit inputs of low voltage 60 or 50 Hz, three phase current). Compressor motors are built in accordance with Trane specifications and guaranteed by the manufacturer for continuous operation at the nameplate rating. A load-limit system provides protection against operation in excess of this rating. The rotor shaft is heat-treated carbon steel and designed such that the critical speed is well above the operating speed. The control circuit prevents motor energization unless positive oil pressure is established. Impellers are keyed directly to the motor shaft and locked in position. Nonferrous, labyrinth-type seals minimize recirculation and gas leakage between the stages of the compressor.
200�600V, 3-phase 60 Hz and 380�415V, 3-phase 50 Hz motors are supplied with six terminal posts for reduced-voltage wye-delta starting. For low-voltage, solid-state starters and AFDs, connecting links are furnished to convert the motor to a 3-lead motor.
2300�13800V, 3-phase 60 Hz and 3300�11000V, 3-phase 50 Hz motors are supplied with three terminal posts for full-voltage (across-the-line) or reduced-voltage (primary reactor or autotransformer) starting. Motor terminal pads are supplied. A removable sheet metal terminal box encloses the terminal board area.
Motor Cooling
Motor cooling is accomplished by a patented refrigerant pump that supplies liquid refrigerant to the motor. The refrigerant circulates uniformly over the stator windings and between the rotor and stator. All motor windings are specifically insulated for operation within a refrigerant atmosphere.
Lubrication
A direct-drive, positive-displacement oil pump is driven by a 120-volt, single-phase, 3/4-hp motor (except for model CVHS chillers, which are oil-free). The motor and pump assembly are submerged in the oil sump to assure a positive oil supply to the compressor bearings at all times. A low watt-density heater maintains the oil temperature to minimize its affinity for refrigerant.
The oil pump for low voltage model CDHH and CVHH chillers is driven by a 380�600V, 50/60 Hz, 3-phase, 2 hp motor, while the oil pump for medium voltage models is driven by a 200�240V, 50/ 60 Hz, 1-phase, 2 hp motor. The motor and pump assembly are submerged in the oil sump to
CTV-PRC007R-EN

Mechanical Specifications
ensure a positive oil supply to the compressor bearings at all times. Two low watt density heaters maintain the oil temperature to minimize its affinity for refrigerant.
The oil tank is constructed in accordance with ASME Section VIII, Division I. It is designed with an open internal volume to accommodate the separation of refrigerant vapor from oil during operation. An electrically actuated ball valve prevents foaming and oil loss during a chiller start. It utilizes two heater elements and a cooling sub-system that consists of a small brazed plate heat exchanger working in combination with a solenoid valve.
Evaporator
Shell and Waterboxes
For CDHF, CDHG, CVHE, CVHF, CVHL, CVHM, and CVHS chillers, the evaporator shell is constructed of carbon steel plate and incorporates a carbon rupture disc in accordance with the ANSI/ASHRAE 15 Safety Code; for CDHH and CVHH, the evaporator shell is constructed of carbon steel plate and incorporates a steel rupture disc in accordance with the ASME Section VIII, Division I. A refrigerant temperature coupling is provided for a low limit controller or customer use.
Multiple pass arrangements are available at 150 psig (1034.2 kPaG) or 300 psig (2068.4 kPaG) water side working pressures, with grooved connections. Flanged connections and/or marinetype waterboxes are also available.
Tube Sheets
A thick carbon steel tube sheet is welded to each end of the shell and then drilled and reamed to accommodate the tubes. Three annular grooves are machined into each tube hole to provide a positive liquid and vapor seal between the refrigerant and water side of the shell after tube rolling. Intermediate tube support sheets are positioned along the length of the shell to avoid contact and relative motion between adjacent tubes.
Tubes
Individually replaceable, seamless tubing available in a variety of materials, depending on the customer's needs, is used as the evaporator heat transfer surface; tubing is available in either 1 inch (25 mm) or 0.75 inch (19 mm) outside diameter. Tubes are externally and internally enhanced, and mechanically expanded into the tube sheets (and are secured to the intermediate supports with tube clips) to provide a leak-free seal and eliminate tube contact and abrasion due to relative motion.
Eliminators
Multiple layers of metal mesh screen form the eliminators and are installed over the tube bundle along the entire length of the evaporator. The eliminators prevent liquid refrigerant carryover into the compressor.
Refrigerant Distribution
A refrigerant distributor on the base of the evaporator assures uniform wetting of the heat transfer surface over the entire length of the shell and under varying loads. High velocity, refrigerant-spray impingement on the tubes is prevented through this design.
Refrigerant Flow Control
A multiple orifice flow-control system maintains the correct pressure differential between the condenser, economizer, and evaporator over the entire range of loading. This patented system contains no moving parts.
Shell Tests
Models CDHF, CDHG, CVHE, CVHF, CVHG, CVHL, CVHM, and CVHS: The refrigerant side of the evaporator shell, complete with tubes but without waterbox covers, is proof-tested at 45 psig (310.3 kPaG), vacuum leak-tested, and finally pressure leak-tested with a helium mass

Mechanical Specifications
spectrometer. The water side of the evaporator shell, with waterboxes in place, is hydrostatically tested at 1.5 times the design working pressure, but not less than 225 psig (1551.3 kPaG).
Models CDHH and CVHH: The refrigerant side of the evaporator shell, complete with tubes but without waterbox covers, is proof-tested at 65 psig (448.2 kPaG) for ASME and 71.5 psig (493.0 kPaG) for PED (European Code), vacuum leak-tested, and finally pressure leak-tested with a helium mass spectrometer. The water side of the evaporator shell, with waterboxes in place, is hydrostatically tested at 1.3 times the design working pressure, but not less than 195 psig (1344.5 kPaG) for 150 psig (1034.2 kPaG) waterboxes or 390 psig (2689.0 kPaG) for 300 psiG (2068.4 kPaG) waterboxes.
Note: These tests are not to be repeated at installation.
Condenser/Heat Recovery Condenser
Shell and Waterboxes
The condenser shell is constructed of carbon steel plate designed and constructed in accordance with ANSI/ASHRAE 15 Safety Code (for CDHF, CDHG, CVHE, CVHF, CVHG, CVHL, CVHM, and CVHS chillers) or ASME Section VIII, Division I (for CDHH and CVHH chillers).
Multiple pass arrangements are available at 150 psig (1034.2 kPaG) or 300 psig (2068.4 kPaG) water side working pressures, with grooved connections. Flanged connections and/or marinetype waterboxes are also available.
Tube Sheets
A thick carbon steel tube sheet is welded to each end of the shell and is drilled and reamed to accommodate the tubes. Three annular grooves are machined into each tube hole to provide a positive liquid and vapor seal between the refrigerant and water sides of the shell after tube rolling. Intermediate tube support sheets are positioned along the length of the shell to avoid contact and relative motion between adjacent tubes.
Tubes
Individually replaceable, seamless copper tubing available in either 1 in. (25 mm) or 0.75 in. (19 mm) outside diameter is used as the evaporator heat transfer surface. Tubes are externally and internally enhanced, and mechanically expanded into the tube sheets (and are secured to the intermediate supports with tube clips) to provide a leak-free seal and eliminate tube contact and abrasion due to relative motion.
Refrigerant Gas Distribution
A baffle plate between the tube bundle and the condenser shell distributes the hot compressordischarge gas longitudinally throughout the condenser and downward over the tube bundle. The baffle plate prevents direct impingement of high velocity compressor-discharge gas upon the tubes.
Shell Tests
Models CDHF, CDHG, CVHE, CVHF, CVHG, CVHL, CVHM, and CVHS: The refrigerant side of the condenser shell, complete with tubes, but without waterbox covers, is proof-tested at 45 psig (310.3 kPaG), vacuum leak-tested, and finally pressure leak-tested with a helium mass spectrometer. The water side of the condenser shell, with waterboxes in place, is hydrostatically tested at 1.5 times the design working pressure, but not less than 225 psig (1551.3 kPaG).
Models CDHH and CVHH: The refrigerant side of the condenser shell, complete with tubes, but without waterbox covers, is proof-tested at 65 psig (448.2 kPaG), vacuum leak-tested, and finally pressure leak-tested with a helium mass spectrometer. The water side of the condenser shell, with waterboxes in place, is hydrostatically tested at 1.3 times the design working pressure, but not less than 195 psig (1344.5 kPaG).
Note: These tests are not to be repeated at installation.

Economizer
CVHE and CVHG CenTraVacTM chillers utilize two-stage economizer (single-stage economizer on CVHF, CVHM, and CVHS units). CVHH two-stage (60 Hz) chillers utilize a single-stage economizer, and CVHH three-stage (50 Hz) chillers utilize a two-stage economizer.
The economizer is constructed in accordance with ASME Section VIII, Division I and consists of either one or two interstage pressure chambers which utilize a multiple orifice system to maintain the correct pressure differential between the condenser, economizer, and evaporator over the entire range of loading. This patented system contains no moving parts.
CDHF and CDHH DuplexTM models (60 Hz) models use a single-stage economizer per circuit. CDHG and CDHH DuplexTM (50 Hz) models use a two-stage economizer per circuit.
Purge System
Standard Features
� 115 Vac, 50/60 Hz, 1-Phase. � 175 watt carbon tank heater. � 12.3 minimum circuit ampacity. � 335 psig (2309.7 kPaG) design pressure high side. � 175 psig (1206.6 kPaG) design pressure low side. � The purge is 25.75 in. (654 mm) high, 27.5 in. (699 mm) wide, and 21.75 in. (552 mm) deep. � The purge uses an R-404A refrigeration circuit with a 1/4 hp condensing unit/10.3 total unit
amps (fan, compressor, expansion valve), and a compressor suction temperature sensor.
The purge tank has a fusible plug, evaporator coil, normally-closed float switch, and the following connections:
� 1/4 in. (6 mm) liquid return with filter-drier and moisture indicator � 5/8 in. (16 mm) vapor line
The expansion valve automatically controls the purge suction pressure to 34 psia (234.4 kPaA).
The pump-out system consists of a pump-out compressor, pump-out solenoid valve, and an exhaust solenoid valve.
The carbon bed tank incorporates a temperature sensor and a regenerative cycle, a 175-watt resistive heater, 150 psig (1034.2 kPaG) pressure relief valve, and a temperature sensor. The carbon bed tank automatically collects and scrubs refrigerant molecules from the noncondensable gas and drives any collected refrigerant vapor back into the chiller. This design keeps the purge efficiency at peak levels throughout its life without the maintenance required on other purges.
The purge controller interfaces with the following intelligent devices on an IPC3 communications link: liquid-level switch, dual relay output, quad relay output, dual triac output, suction temperature sensor, and carbon temperature sensor. Fifty hertz applications have a separate voltage correction transformer.
The purge controller communicates with the Tracer� AdaptiViewTM controller and display, which is mounted on the front of the chiller control panel. Descriptive text indicates purge operating mode, status, set points, purge operating data reports, diagnostics, and alarms. Operating modes Stop, On, Auto, and Adaptive operate the purge refrigeration circuit and accumulate noncondensables with or without the chiller running.
Chiller Controller
The microcomputer control panel is factory installed and tested on the CenTraVacTM chiller. All controls necessary for the safe and reliable operation of the chiller are provided including oil management (when required), purge operation, and interface to the starter or Adaptive Frequency DriveTM (AFD). The control system is powered by a control power transformer included in the starter panel. The microcomputer control system processes the leaving evaporator fluid temperature sensor signal to satisfy the system requirements across the entire load range.

CTV-PRC007R-EN
Mechanical Specifications
The microprocessor controller is compatible with reduced-voltage or full-voltage electromechanical starters, variable-speed drives, or solid-state starters. Depending on the applicability, the drives may be factory mounted or remote mounted.
The controller will load and unload the chiller via control of the stepper motor/actuator which drives the inlet guide vanes open or closed. The load range can be limited either by a current limiter or by an inlet guide vane limit (whichever controls the lower limit). It will also control the evaporator and condenser pumps to ensure proper chiller operation.
Approximately 200 diagnostic checks are made and displayed when a fault is detected. The display indicates the fault, the type of reset required, the time and date the diagnostic occurred, the mode in which the machine was operating at the time of the diagnostic, and a help message. A diagnostic history displays the last 10 diagnostics with the time and date of their occurrence.
The panel features machine protection shutdown requiring manual reset for:
� Low oil flow (except for model CVHS chillers, which are oil-free) � Low oil temperature (except for model CVHS chillers, which are oil-free) � Actuator drive circuit fault � Low differential oil pressure (except for model CVHS chillers, which are oil-free) � Extended compressor surge � Excessive loss of communication � High condenser refrigerant pressure � Critical sensor or detection circuit faults � Low evaporator refrigerant temperature � Free-cooling valve closure failure (free cooling applications only)
The display also provides reports that are organized into six groupings: Evaporator, Condenser, Compressor, Motor, Purge, and the ASHRAE Chiller Log. Each report contains data that is accessed by scrolling through the menu items. Each grouping will have a heading which describes the type of data in that grouping. This data includes:
� Phase currents � Last 10 diagnostics � Phase voltages � Current limit setpoint � Water flows (optional) � Purge suction temperature � Oil temperature and pressures (except for model CVHS chillers, which are oil-free) � Motor winding temperatures � Current chiller operating mode � Water pressure drops (optional) � Watts and power factor (optional) � Bearing temperatures (optional) � Outdoor air temperature (optional) � Evaporator refrigerant temperature � All water temperatures and setpoints � Condenser liquid refrigerant temperature � Compressor starts and hours running � Saturated refrigerant temperatures and pressures � Refrigerant detection external to chiller in ppm (optional) � Control source (i.e., local panel, external source, remote BAS)
The controller is capable of receiving signals from a variety of control sources (which are not mutually exclusive--i.e., multiple control sources can coexist simultaneously) and of being programmed at the keypad as to which control source has priority. Control sources can be:
� Tracer� building controls (interface optional) � The local operator interface (standard) � A 4�20 mA or 2�10 Vdc signal from an external source (interface optional, control source not
supplied by chiller manufacturer) � Process computer (interface optional, control source not supplied by chiller manufacturer)
101
Mechanical Specifications
� Generic BAS (interface optional, control source not supplied by chiller manufacturer)
The control source with priority will then determine the active setpoints via the signal that is sent to the control panel.
Isolation Pads
Isolation pads are supplied with each CenTraVacTM chiller for placement under all support points. They are constructed of molded neoprene.
Refrigerant and Oil Charge
A full charge of refrigerant and oil is supplied with each unit (except for model CVHS chillers, which are oil-free). The oil ships in the unit's oil sump and the refrigerant ships directly to the job site from refrigerant suppliers.
0.0% Leak-Tight Warranty
The CenTraVacTM chiller features a 5-year limited Leak-Tight Warranty which is valid for the lesser of 60 months from initial start-up or 66 months from date of shipment. The limited LeakTight Warranty covers models CDHF, CDHH, CVHE, CVHF, CVHH, CVHL, CVHM, and CVHS chillers installed in the United States or Canada. The Company's obligations and liabilities under this warranty are limited to furnishing replacement refrigerant due to manufacturing defect (as an example, a rupture disc blowing due to equipment room mishaps not covered). No other parts or labor are covered under this limited warranty. No liability whatever shall attach to the Company until appropriate actions have been taken (acceptable to Company) to eliminate the source of the leak, and then said liability shall be limited to furnishing the replacement refrigerant.
If the chiller is placed under a comprehensive Trane service and maintenance agreement (Trane "Select Agreement" or better) prior to the expiration of the standard Leak-Tight Warranty, the protection against refrigerant loss shall continue under the Trane Select Agreement for as long as an active Trane Select Agreement remains in effect without interruption.
If a 10-Year Parts, Labor and Refrigerant Warranty was purchased for the chiller and the chiller is placed under a Trane Select Agreement (or better) prior to the expiration of the 10-Year Parts, Labor and Refrigerant Warranty, the protection against refrigerant loss shall continue under the Trane Select Agreement for as long as an active Trane Select Agreement remains in effect without interruption.
Thermometer Wells and Sight Glasses
In addition to the thermometer wells provided for use with the standard unit safety controls, a well is provided for measurement of the liquid refrigerant condensing temperature and a coupling for the evaporating temperatures. Sight glasses are provided for monitoring oil charge level and oil flow (except for model CVHS chillers, which are oil free, compressor rotation, and purge condenser drum.
Insulation
Factory applied insulation is available as an option on all units. All low temperature surfaces are covered with 3/4 in. (19 mm) Armaflex� II or equal, with a thermal conductivity = 0.28 Btu/h�ft2 (0.79 W/m2), including the evaporator, waterboxes, and suction elbow and for CDHH and CVHH
chillers, also including the economizer and motor cooling lines. For CDHF, CDHG, CVHE, CVHF,
CVHG, CVHL, CVHM, and CVHS chillers, the economizer and motor cooling lines are insulated
with 3/8 in. (9.5 mm) and 1/2 in. (12.7 mm) insulation respectively.
Refrigerant Pumpout/Reclaim Connections
Connections are factory-provided as standard to facilitate refrigerant reclaim/removal required during maintenance or overhaul in accordance with ANSI/ASHRAE 15.

Appendix E: CenTraVac Chiller Operating Cycles
Compressor Motor
All CenTraVacTM chiller motors are cooled by liquid refrigerant surrounding the motor windings and rotor. Using liquid refrigerant results in uniform low temperatures throughout the motor, which prolongs motor life over open designs. Motor heat is rejected out to the cooling tower, which helps keep the equipment room at a desirable temperature.
Induction--A specially designed squirrel-cage, two-pole motor suitable for 60 or 50 Hz, threephase current.
Model CVHM and CVHS: Permanent Magnet--A specially designed, six-pole motor suitable for unit inputs of low voltage 60 or 50 Hz, three-phase current.
Fixed Orifice Flow Control
For proper refrigerant flow control at all load conditions, the CenTraVacTM chiller design incorporates the Trane� patented fixed orifice system. The orifices are optimized for full- and part-load chiller performance during the selection process. It eliminates float valves, thermal expansion valves, and other moving parts. Since there are no moving parts, reliability is increased.
Low Speed, Direct Drive Compressor
The direct drive, low speed compressor with a motor shaft supported by only two bearings provides quiet, reliable and more efficient operation.
With only one primary rotating component--the rotor/impeller assembly--the CenTraVacTM chiller is inherently quieter than gear-driven compressors. Typical CenTraVacTM chiller sound measurements are among the quietest in the industry. Trane can guarantee sound levels with factory testing and measurements in accordance with AHRI Standard 1280.
Compressors using gears suffer mesh losses and extra bearing losses in the range of three to five percent at full load. Since these losses are fairly constant over the load range, increasingly larger losses (as a percentage) result as the load decreases.
Multiple Stages of Compression
The multi-stage design provides a stable operating envelope to meet dynamic system needs for reliable operation in all real-world conditions. It also enables the use of a flash economizer for better efficiency.
Inlet Guide Vanes
Part-load performance is further improved through the use of moveable inlet guide vanes. Inlet guide vanes improve performance by throttling refrigerant gas flow to exactly meet part-load requirements and by pre-rotating the refrigerant gas. Pre-rotation minimizes turbulence and increases efficiency.
Flash Economizer
CenTraVacTM chillers leverage a multi-stage design with two or three impellers, making it possible to flash refrigerant gas at intermediate pressure(s) between the condenser and evaporator, significantly increasing chiller efficiency.
� Two-stage CenTraVacTM chillers (60 Hz models CDHF, CDHH, CVHF, CVHM, CVHS, and CVHH) utilize a single-stage economizer, providing up to 4.5 percent better efficiency than designs with no economizer.
� Three-stage CenTraVacTM chillers (60/50 Hz model CVHE and 50 Hz models CDHG, CDHH, CVHG, and CVHH) utilize a two-stage economizer, providing up to 7 percent better efficiency than designs with no economizer.
These improvements in efficiency are not possible in single-stage chillers where all compression is done by one impeller.

Appendix E: CenTraVac Chiller Operating Cycles
Refrigerant/Oil Pump Motor
Models CDHF, CDHG, CVHE, CVHF, CVHG, CVHL, and CVHM: The oil pump motor is a 120 volt, 60/50 Hz, 3/4 hp, 1-phase motor with protective fusing and panel mounted contactor.
Models CDHH and CVHH: Low voltage chillers will have a 200�240V 60/50 Hz, 1-phase, 2 hp motor.
Purge System
The purge design features a high-efficiency carbon filter with an automatic regeneration cycle. The filter separates refrigerant from non-condensable gas and collects it. When the filter senses that it is full, the regeneration cycle begins, and reclaimed refrigerant is automatically returned to the chiller. This keeps the purge efficiency at its peak without the need to exchange carbon canisters.
Normal operating efficiency does not exceed 0.02 units of refrigerant lost per unit of dry air removed. The purge system can be operated at any time, independent of chiller operation, per ASHRAE Standard 147.

Note: RE = Refrigeration Effect
The pressure-enthalphy (P-H) diagrams describe refrigerant flow through the major chiller components. The diagrams confirm the superior cycle efficiency of the multi-stage CenTraVacTM compressor with economizer.
Evaporator--A liquid-gas refrigerant mixture enters the evaporator (point 1). Liquid refrigerant is vaporized (point 2) as it absorbs heat from the system cooling load. The vaporized refrigerant then flows into the compressor's first stage.
Compressor First Stage--Refrigerant gas is drawn from the evaporator into the compressor. The first-stage impeller accelerates the gas, increasing its temperature and pressure into the first stage of the compressor (point 3).
Compressor Second Stage--Refrigerant gas leaving the first stage of the compressor is mixed with cooler refrigerant gas from the low pressure side of the economizer. This mixing lowers the
116
CTV-PRC007R-EN
Appendix F: CenTraVac Chiller Pressure-Enthalpy (P-H) Diagrams
enthalpy of the mixture entering the second stage. The second-stage impeller accelerates the gas, further increasing its temperature and pressure (point 4).
Compressor Third Stage--For CenTraVacTM chillers with three-stage compressors, the refrigerant gas leaving the compressor's second stage is mixed with cooler refrigerant gas from the high pressure side of the two-stage economizer. This mixing lowers the enthalpy of the gas mixture entering the third stage of the compressor. The third-stage impeller accelerates the gas, further increasing its temperature and pressure (point 5), then discharges it to the condenser.
Condenser--Refrigerant gas enters the condenser where the system cooling load and heat of compression are rejected to the condenser water circuit. This heat rejection cools and condenses the refrigerant gas to a liquid (point 6).
For three-stage CenTraVacTM chillers with the patented two-stage economizer and refrigerant orifice system, liquid refrigerant leaving the condenser (point 6) flows through the first orifice and enters the high pressure side of the economizer. The purpose of this orifice and economizer is to pre-flash a small amount of refrigerant at an intermediate pressure (P1). Pre-flashing some liquid refrigerant cools the remaining liquid (point 7). Refrigerant leaving the first stage economizer flows through the second orifice and enters the second-stage economizer. Some refrigerant is pre-flashed at an intermediate pressure (P2). Pre-flashing the liquid refrigerant cools the remaining liquid (point 8).
For two-stage CenTraVacTM chillers with economizer and refrigerant orifice system, liquid refrigerant leaving the condenser (point 6) flows through the first orifice system and enters the economizer. The purpose of the orifice and economizer is to pre-flash a small amount of refrigerant at an intermediate pressure (P1) between the evaporator and condenser. Pre-flashing some liquid refrigerant cools the remaining liquid (point 8).
Another benefit of flashing refrigerant is to increase the total evaporator refrigeration effect from RE1 to RE; refer to "Flash Economizer," p. 114.
To complete the operating cycle, liquid refrigerant leaving the economizer (point 8) flows through a second orifice system. Here, refrigerant pressure and temperature are reduced to evaporator conditions (point 1).
The pressure enthalpy (P-H) diagrams show refrigerant flow through the major chiller components. The diagrams confirm the superior cycle efficiency of the multi-stage Agility compressor with economizer.
Evaporator -- A liquid gas refrigerant mixture enters the evaporator (point 9). Liquid refrigerant is vaporized (point 1) as it absorbs heat from the system cooling load. The vaporized refrigerant then flows into the compressor's first stage.
Compressor First Stage -- Refrigerant gas is drawn from the evaporator into the compressor. The first stage impeller accelerates the gas, increasing its temperature and pressure into the first state of the compressor (point 2).
Compressor Second Stage -- Refrigerant gas leaving the first stage of the compressor is mixed with cooler refrigerant gas from the secondary side of the brazed plate heat exchanger economizer (point 7). This mixing lowers the enthalpy of the mixture entering the second stage. The second stage impeller accelerates the gas, further increasing its temperature and pressure (point 3).
Condenser -- Refrigerant gas enters the condenser where the system cooling load and heat of compression are rejected to the condenser water circuit. This heat rejection cools and condenses the refrigerant gas to a liquid (point 4). The liquid refrigerant flows through an internal subcooler, where additional energy in the refrigerant liquid passes into the condenser water circuit (point 5).
Economizer -- The liquid refrigerant is split such that the primary flow is directed through one side of the brazed plate heat exchanger economizer, while a significantly smaller portion of the flow passes through an expansion valve, lowering refrigerant pressure and temperature before entering phase refrigerant (point 6). The heat transfer between the primary and secondary channels in the BPHE results in further subcooling of the primary liquid (point 8) as it rejects heat to, and consequently superheats, the secondary flow. The additional subcooling of the liquid prior to expansion through the main electronically controlled valve (point 9) effectively increases the overall capacity of the evaporator.
