Air-Cooled Series R™

Helical-Rotary Liquid Chiller

Model RTAC 120 to 200

(400 to 760kw - 50 Hz)

Built for the Industrial and

Commercial Markets

RLC-PRC005-E4

The new Trane Model RTAC Air-Cooled

Helical-Rotary Chiller is the result of a

search for higher reliability, higher

energy efficiency, and lower sound

levels for today’s environment.

In an effort to reduce energy consumed

by HVAC equipment and to continually

produce chilled water, Trane has

developed the Model RTAC chiller with

higher efficiencies and a more reliable

design than any other air cooled chiller

available on the market today.

The Model RTAC chiller uses the proven

design of the Trane helical-rotary

compressor, which embraces all of the

design features that have made the

Trane helical-rotary compressor liquid

chillers such a success since 1987.

What Is New

The RTAC offers the same high

reliability coupled with greatly improved

energy efficiency, vastly reduced

physical footprint, and improved

acoustical performance, due to its

advanced design, low-speed, direct-

drive compressor, and proven

Series R™ performance.

The major differences between the

Series R, Model RTAC and Model RTAA

are:

• Smaller physical footprint

• Lower sound levels

• Higher energy efficiency

• Designed specifically for operating

with environmentally-safe HFC-134a.

The Series R Model RTAC helical-rotary

chiller is an industrial-grade design, built

for both the industrial and commercial

markets. It is ideal for schools, hospitals,

retailers, office buildings, and industrial

applications.

Water Chiller Systems Business Unit The Series R™

Helical-Rotary Compressor

• Unequaled reliability. The next

generation Trane helical-rotary

compressor is designed, built, and

tested to the same demanding and

rugged standards as the Trane scroll

compressors, the centrifugal

compressors, and the previous

generation helical-rotary compressors

used in both air- and water-cooled

chillers for more than 13 years.

• Years of research and testing. The

Trane helical-rotary compressor has

amassed thousands of hours of

testing, much of it at severe operating

conditions beyond normal commercial

air-conditioning applications.

• Proven track record. The Trane

Company is the world’s largest

manufacturer of large helical-rotary

compressors used for refrigeration.

Over 90,000 compressors worldwide

have proven that the Trane helical-

rotary compressor has a reliability rate

of greater than 99.5 percent in the first

year of operation—unequalled in the

industry.

• Resistance to liquid slugging. The

robust design of the Series R

compressor can ingest amounts of

liquid refrigerant that normally would

severely damage reciprocating

compressor valves, piston rods, and

cylinders.

• Fewer moving parts. The helical-rotary

compressor has only two rotating

parts: the male rotor and the female

rotor. Unlike reciprocating

compressors, the Trane helical-rotary

compressor has no pistons,

connecting rods, suction and

discharge valves, or mechanical oil

pump. In fact, a typical reciprocating

compressor has 15 times as many

critical parts as the Series R

compressor. Fewer moving parts leads

to increased reliability and longer life.

• Direct-drive, low-speed, semi-hermetic

compressor for high efficiency and

high reliability.

• Field-serviceable compressor for easy

maintenance.

• Suction-gas-cooled motor. The motor

operates at lower temperatures for

longer motor life.

• Five minute start-to-start and two

minute stop-to-start anti-recycle timer

allows for closer water-loop

temperature control.

Improved

Acoustical

Performance

RLC-PRC005-E4

The sound levels of the Series R Model

RTAA have been steadily improved

since its introduction. With the advent of

the Model RTAC, sound levels are

reduced significantly by addressing two

major sources: the compressor and the

refrigerant piping. First, the compressor

has been specifically designed to

minimize sound generation. Second, the

refrigerant components and piping have

been optimized to reduce sound

propagation throughout the system. The

result: sound levels achieved on the

Model RTAC represent the lowest sound

levels ever on Trane air-cooled helical-

rotary compressor water chillers.

Superior Efficiency Levels:

The Bar Has Been Raised

The standard-efficiency Trane Model

RTAC has COP levels up to 2.90 kW/kW

[9.9 EER] (including fans), while the

premium-efficiency, or high-efficiency,

units leap to COP levels of 3.08 kW/kW

[10.51 EER] (including fans).

The modern technology of the RTAC

with the efficient direct-drive

compressor, the flooded evaporator, the

unique design to separate liquid and

vapor, the electronic expansion valve,

and the revolutionary Tracer™Chiller

Controls, has permitted Trane to achieve

these efficiency levels, unmatched in the

industry.

Precise Rotor Tip Clearances

Higher energy efficiency in a helical-

rotary compressor is obtained by

reducing the rotor tip clearances. This

next-generation compressor is no

exception. With today’s advanced

manufacturing technology, clearances

can be controlled to even tighter

tolerances. This reduces the leakage

between high- and low-pressure cavities

during compression, allowing for more

efficient compressor operation.

Capacity Control and Load Matching

The combination patented unloading

system on Trane helical-rotary

compressors uses the variable

unloading valve for the majority of the

unloading function. This allows the

compressor to modulate infinitely, to

exactly match building load and to

maintain chilled-water supply

temperatures within ± 0.3°C [±0.5°F] of

the set point. Reciprocating and helical-

rotary chillers that rely on stepped

capacity control must run at a capacity

equal to or greater than the load, and

typically can only maintain water

temperature to around ± 1°C [±2°F].

Much of this excess capacity is lost

because overcooling goes toward

removing building latent heat, causing

the building to be dried beyond normal

comfort requirements. When the load

becomes very low, the compressor also

uses a step unloader valve, which is a

single unloading step to achieve the

minimum unloading point of the

compressor. The result of this design is

optimized part-load performance far

superior to single reciprocating

compressors and step-only helical-

rotary compressors.

Compact Physical Size

The Trane Model RTAC chiller averages a

20 percent reduction in physical

footprint, while the greatest change is

actually 40 percent smaller when

compared against the previous design.

This improvement makes the RTAC the

smallest air-cooled chiller in the industry

and a prime candidate for installations

that have space constraints. All physical

sizes were changed without sacrificing

the side clearances needed to supply

fresh airflow without coil starvation—the

tightest operational clearances in the

industry.

Close Spacing Installation

The air-cooled Series R™chiller has the

tightest recommended side clearance in

the industry, 1.2 meters, but that is not

all. In situations where equipment must

be installed with less clearance than

recommended, which frequently occurs

in retrofit applications, restricted airflow

is common. Conventional chillers may

not work at all. However, the air-cooled

Series R chiller with the Adaptive

Control™microprocessor will make as

much chilled water as possible given the

actual installed conditions, stay on-line

during any unforeseen abnormal

conditions, and optimize its

performance. Consult your Trane sales

engineer for more details.

Factory Testing Means Trouble-Free

Start-up

All air-cooled Series R chillers are given

a complete functional test at the factory.

This computer-based test program

completely checks the sensors, wiring,

electrical components, microprocessor

function, communication capability,

expansion valve performance, and fans.

In addition, each compressor is run-

tested to verify capacity and efficiency.

Where applicable, each unit is factory

preset to the customer’s design

conditions. An example would be the

leaving-liquid temperature set point. The

result of this test program is that the

chiller arrives at the job site fully tested

and ready for operation.

Factory-Installed and Tested Controls

and Options Speed Installation

All Series R chiller options, including

main power-supply disconnect, low

ambient control, ambient temperature

sensor, low ambient lockout,

communication interface and ice-

making controls are factory installed and

tested. Some manufacturers send

accessories in pieces to be field

installed. With Trane, the customer saves

on installation expense and has

assurance that ALL chiller controls and

options have been tested and will

function as expected.

RLC-PRC005-E4

The End of Nuisance

Trip-Outs and

Unnecessary Service Calls?

The Adaptive Control™microprocessor

system enhances the air-cooled Series R

chiller by providing the very latest chiller

control technology. With the Adaptive

Control microprocessor, unnecessary

service calls and unhappy tenants are

avoided. The unit does not nuisance-trip

or unnecessarily shut down. Only when

the Tracer chiller controls have

exhausted all possible corrective

actions, and the unit is still violating an

operating limit, will the chiller shut

down. Controls on other equipment

typically shut down the chiller, usually

just when it is needed the most.

For Example:

A typical five-year-old chiller with dirty

coils might trip out on high-pressure

cutout on a 38°C [100°F] day in August.

A hot day is just when comfort cooling

is needed the most. In contrast, the air-

cooled Series R chiller with an Adaptive

Control microprocessor will stage fans

on, modulate the electronic expansion

valve, and modulate the slide valve as it

approaches a high-pressure cutout,

thereby keeping the chiller on line when

you need it the most.

System Options: Ice Storage

Trane air-cooled chillers are well-suited

for ice production. The unique ability to

operate at decreased ambient

temperature while producing ice results

in approximately the same amount of

work for the compressor. An air-cooled

machine typically switches to ice

production at night. Two things happen

under this assumption. First, the leaving

brine temperature from the evaporator

4. Freeze ice storage

5. Freeze ice storage when comfort

cooling is required

6. Off

Tracer optimization software controls

operation of the required equipment

and accessories to easily move from

one mode of operation to another. For

example: even with ice-storage systems,

there are numerous hours when ice is

neither produced nor consumed, but

saved. In this mode, the chiller is the

sole source of cooling. For example, to

cool the building after all ice is produced

but before high electrical-demand

charges take effect, Tracer sets the air-

cooled chiller leaving-fluid set point to

its most efficient setting and starts the

chiller, chiller pump, and load pump.

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 the ice and the chiller in

meeting the cooling load.

The capacity of the chiller plant is

extended by operating the chiller and ice

in tandem. Tracer rations the ice,

augmenting chiller capacity while

reducing cooling costs. When ice is

produced, Tracer will lower the air-

cooled chiller leaving-fluid set point and

start the chiller, ice and chiller pumps,

and other accessories. Any incidental

loads that persists while producing ice

can be addressed by starting the load

pump and drawing spent cooling fluid

from the ice storage tanks.

applications, contact your local Trane

sales office.

is lowered to around -5.5 to -5°C [22 to

24°F]. Second, the ambient temperature

has typically dropped about 8.3 to 11°C

[15 to 20°F] from the peak daytime

ambient. This effectively places a lift on

the compressors that is similar to

daytime running conditions. The chiller

can operate in lower ambient at night

and successfully produce ice to

supplement the next day’s cooling

demands.

The Model RTAC produces ice by

supplying ice storage tanks with a

constant supply of glycol solution. Air-

cooled chillers selected for these lower

leaving-fluid temperatures are also

selected for efficient production of

chilled fluid at nominal 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.

When cooling is required, ice-chilled

glycol 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 air-cooled 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 is operated in

six different modes, each optimized for

the utility cost at a particular time of day.

1. Provide comfort cooling with chiller

2. Provide comfort cooling with ice

3. Provide comfort cooling with ice and

chiller

Application Considerations

9

RLC-PRC005-E4

Certain application constraints should

be considered when sizing, selecting,

and installing Trane air-cooled Series R

chillers. Unit and system reliability is

often dependent on properly and

completely complying with these

considerations. When the application

varies from the guidelines presented, it

should be reviewed with your local

Trane sales engineer.

Unit Sizing

Unit capacities are listed in the

performance data section. Intentionally

oversizing a unit to ensure adequate

capacity is not recommended. Erratic

system operation and excessive

compressor cycling are often a direct

result of an oversized chiller. In addition,

an oversized unit is usually more

expensive to purchase, install, and

operate. If oversizing is desired, consider

using two units.

Water Treatment

Dirt, scale, products of corrosion, and

other foreign material will adversely

affect heat transfer between the water

and system components. Foreign matter

in the chilled-water system can also

increase pressure drop and,

consequently, reduce water flow. Proper

water treatment must be determined

locally, depending on the type of system

51°C [125°F], and selecting the low-

ambient option will increase the

operational capability of the water chiller

to ambient temperatures as low as 18°C

[0°F]. For operation outside of these

ranges, contact the local Trane sales

office.

Water Flow Limits

The minimum water flow rates are

given in Tables G-1 and G-2. Evaporator

flow rates below the tabulated values

will result in laminar flow and cause

freeze-up problems, scaling,

stratification, and poor control. The

maximum evaporator water flow rate is

also given in the general data section.

Flow rates exceeding those listed may

result in excessive tube erosion.

Flow Rates Out of Range

Many process cooling jobs require flow

rates that cannot be met with the

minimum and maximum published

values within the Model RTAC

evaporator. A simple piping change can

alleviate this problem. For example: a

plastic injection molding process

requires 5.0 Lps [80 gpm] of 10°C [50°F]

water and returns that water at 15.6°C

[60°F]. The selected chiller can operate at

these temperatures, but has a minimum

flow rate of 7.6 Lps [120 gpm]. The

following system can satisfy the process.

and local water characteristics. Neither

salt nor brackish water is recommended

for use in Trane air-cooled Series R

chillers. Use of either will lead to a

shortened chiller life. The Trane

Company encourages the employment

of a reputable water-treatment specialist,

familiar with local water conditions, to

assist in this determination and in the

establishment of a proper water-

treatment program.

Effect of Altitude on Capacity

Air-cooled Series R chiller capacities

given in the performance data tables are

for use at sea level. At elevations

substantially above sea level, the

decreased air density will reduce

condenser capacity and, therefore, unit

capacity and efficiency. The adjustment

factors in Table F-1 can be applied

directly to the catalog performance data

to determine the unit’s adjusted

performance.

Ambient Limitations

Trane air-cooled Series R chillers are

designed for year-round operation over

a range of ambient temperatures. The

air-cooled Model RTAC chiller will

operate in ambient temperatures of 4 to

46°C [25 to 115°F]. Selecting the high-

ambient option will allow the chiller to

Leaving-Water Temperature Range

Trane air-cooled Series R chillers have

three distinct leaving-water categories:

standard, low temperature, and ice

making. The standard leaving-solution

temperature range is 4.4 to 15.6°C [40 to

60°F]. Low-temperature machines

produce leaving-liquid temperatures

less than 4.4°C [40°F]. Since liquid

supply temperature set points less than

4.4°C [40°F] result in suction

temperatures at or below the freezing

point of water, a glycol solution is

required for all low-temperature

machines. Ice-making machines have a

leaving-liquid temperature range of -6.7

to 15.6°C [20 to 60°F]. Ice-making

controls include dual set point controls

and safeties for ice making and standard

cooling capabilities. Consult your local

Trane sales engineer for applications or

selections involving low temperature or

ice making machines. The maximum

water temperature that can be circulated

through an evaporator when the unit is

not operating is 42°C [108°F].

Leaving-Water Temperature

Out of Range

Similar to the flow rates above, many

process cooling jobs require

temperature ranges that cannot be met

with the minimum and maximum

published values for the Model RTAC

evaporator. A simple piping change can

alleviate this problem. For example: a

laboratory load requires 7.6 Lps [120

gpm] of water entering the process at

29.4°C [85°F] and returning at 35°C

[95°F]. The accuracy required is higher

than the cooling tower can give. The

selected chiller has adequate capacity,

but has a maximum leaving-chilled-

water temperature of 15.6°C [60°F].

In the example shown, both the chiller and

process flow rates are equal. This is not

necessary. For example, if the chiller had a

higher flow rate, there would be more water

bypassing and mixing with warm water.

Supply-Water Temperature Drop

The performance data for the Trane air-

cooled Series R chiller is based on a

chilled-water temperature drop of 6°C

[10.8°F]. Chilled-water temperature

drops from 3.3 to 10°C [6 to 18°F] may

be used as long as minimum and

maximum water temperature, and

minimum and maximum flow rates, are

not violated. Temperature drops outside

this range are beyond the optimum

range for control, and may adversely

affect the microcomputer’s ability to

maintain an acceptable supply-water

temperature range. Further, temperature

drops of less than 3.3°C [6°F] may result

in inadequate refrigerant superheat.

Sufficient superheat is always a primary

concern in any direct-expansion

refrigerant system and is especially

important in a package chiller where the

evaporator is closely coupled to the

compressor. When temperature drops

are less than 3.3°C [6°F], an evaporator

runaround loop may be required.

CV Pump

Application Considerations

11

RLC-PRC005-E4

Variable Flow in the Evaporator

An attractive chilled-water system

option may be a variable primary flow

(VPF) system. VPF systems present

building owners with several cost-

saving benefits that are directly related

to the pumps. The most obvious cost

savings result from eliminating the

secondary distribution pump, which in

turn avoids the expense incurred with

the associated piping connections

(material, labor), electrical service, and

variable-frequency drive. Building

owners often cite pump-related energy

savings as the reason that prompted

them to install a VPF system. With the

help of a software analysis tool such as

System Analyzer™, TRACE™, or DOE-2,

you can determine whether the

anticipated energy savings justify the

use of variable primary flow in a

particular application. It may also be

easier to apply variable primary flow in

an existing chilled-water plant. Unlike

the “decoupled” design, the bypass can

be positioned at various points in the

chilled-water loop and an additional

pump is unnecessary. The evaporator in

the Model RTAC can withstand up to 50

percent water flow reduction as long as

this flow is equal to or above the

minimum flow-rate requirements. The

microprocessor and capacity control

algorithms are designed to take a

minimum of 10 percent change in water

flow rate per minute.

Short Water Loops

The proper location of the temperature

control sensor is in the supply (outlet)

water connection or pipe. This location

allows the building to act as a buffer and

assures a slowly-changing return-water

temperature. If there is not a sufficient

volume of water in the system to

provide an adequate buffer, temperature

control can be lost, resulting in erratic

system operation and excessive

compressor cycling. A short water loop

has the same effect as attempting to

control using the building return water.

Typically, a two-minute water loop is

sufficient to prevent a short water loop.

Therefore, as a guideline, ensure that

the volume of water in the evaporator

loop equals or exceeds two times the

evaporator flow rate. For a rapidly

changing load profile, the amount of

volume should be increased. To prevent

the effect of a short water loop, the

following item should be given careful

consideration: a storage tank or larger

header pipe to increase the volume of

water in the system and, therefore,

reduce the rate of change of the return

water temperature.

Applications Types

• Comfort cooling

• Industrial process cooling

• Ice or thermal storage

• Low-temperature process cooling.

Ice Storage Provides

Reduced Electrical Demand

An ice-storage system uses a standard

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

big 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 period of time, the chiller

can be repaired before building

occupants feel any loss of comfort.

The Trane Model RTAC chiller is uniquely

suited to low-temperature applications

like ice storage because of the ambient

relief experienced at night. This allows

the Model RTAC chiller to produce ice

efficiently, with less stress on the

machine.

Simple and smart control strategies are

another advantage the Model RTAC

chiller offers 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.

Selection Procedure

Simple Interface with Other

Control Systems

Microcomputer controls afford a simple

interface with other control systems,

such as time clocks, building automation

systems, and ice storage systems. This

means you can have the flexibility to

meet job requirements while not having

to learn a complicated control system.

This setup has the same standard

features as a stand-alone water chiller,

with the possibility of having the

following optional features.

Alarm Indication Contacts

The unit provides four single-pole,

double-throw contact closures to

indicate that a failure has occurred, if

any compressors are running, or if the

compressors are running at maximum

capacity. These contact closures may be

used to trigger job-site-provided alarm

lights or alarm bells.

Tracer Summit™ Controls —

Interface with the Trane

Integrated Comfort System (ICS)

Trane Chiller Plant Manager with ICS

The Tracer Chiller Plant Manager

building management system provides

building automation and energy

management functions through stand-

alone control. The Chiller Plant Manager

is capable of monitoring and controlling

your entire chiller plant system.

Application software available:

• Time-of-day scheduling

• Duty cycle

• Demand limiting

• Chiller sequencing

• Process control language

• Boolean processing

• Zone control

• Reports and logs

• Custom messages

• Run time and maintenance

• Trend log

• PID control loops

And of course, the Trane Chiller Plant

Manager panel can be used on a stand-

alone basis or tied into a complete

building automation system.

When the air-cooled Series R™chiller is

used in conjunction with a Trane Tracer™

system, the unit can be monitored and

controlled from a remote location. The

air-cooled Series R chiller can be

controlled to fit into the overall building

automation strategy by using time-of-

day scheduling, timed override, duty

cycling, demand limiting, and chiller

sequencing. A building owner can

completely monitor the air-cooled Series

R chiller from the Tracer system, since all

of the monitoring information indicated

on the microcomputer can be read on

the Tracer system display. In addition, all

the powerful diagnostic information can

be read back at the Tracer system. Best

of all, this powerful capability comes

over a single twisted pair of wires! Air-

cooled Series R chillers can interface

with many different external control

systems, from simple stand-alone units

to ice-making systems. Each unit

requires a single-source, three-phase

power supply and a 115-volt power

supply. The 115-volt supply handles the

freeze protection for the evaporator

heaters.

A single twisted pair of wires tied

directly between the air-cooled Series R™

chiller and a Tracer™system provides

control, monitoring, and diagnostic

capabilities. Control functions include

auto/stop, adjustment of leaving-water-

temperature set point, compressor

operation lockout for kW demand

limiting, and control of ice-making

mode. The Tracer system reads

monitoring information such as

entering- and leaving-evaporator-water

temperatures and outdoor air

temperature. Over 60 individual

diagnostic codes can be read by the

Tracer system. In addition, the Tracer

system can provide sequencing control

for two to six units on the same chilled-

water loop. Pump sequencing control

can be provided from the Tracer system.

Tracer ICS is not available in conjunction

with the remote display or the external

set point capability.

Ice-Making Systems Controls

An ice-making option may be ordered

with the air-cooled Series R™chiller. The

unit will have two operating modes, ice

making and normal daytime cooling. In

the ice-making mode, the air-cooled

Series R chiller will operate at full

compressor capacity until the return

chilled-fluid temperature entering the

evaporator meets the ice-making set

point. This ice-making set point is

manually adjusted on the unit’s

microcomputer. Two input signals are

required to the air-cooled Series R chiller

for the ice-making option. The first is an

auto/stop signal for scheduling, and the

second is required to switch the unit

between the ice-making mode and

normal daytime operation. The signals are

provided by a remote job site building-

automation device such as a time clock or

a manual switch. In addition, the signals

may be provided over the twisted wire

pair from a Tracer™system.

Controls

Safety Controls

A centralized microcomputer offers a

higher level of machine protection.

Because the safety controls are smarter,

they limit compressor operation in order

to avoid compressor or evaporator

failures, thereby minimizing nuisance

shutdowns. Tracer™Chiller Controls

directly senses the control variables that

govern the operation of the chiller:

motor current draw, evaporator

pressure, condenser pressure, and so

forth. When any one of these variables

approaches a limit condition at which

the unit may be damaged or shut down

on a safety, Tracer Chiller Controls takes

corrective action to avoid shutdown and

keep the chiller operating. It does this

through combined actions of

compressor slide-valve modulation,

electronic expansion-valve modulation,

and fan staging. Tracer Chiller Controls

optimizes total chiller power

consumption during normal operating

conditions. During abnormal operating

Tracer™Chiller Control human interfaces

The Trane air-cooled Series R Model

RTAC chiller offers two easy-to-use

operator interface panels, the EasyView,

and the DynaView.

Standard Features

External Auto/Stop

A job-site-provided contact closure will

turn the unit on and off.

Chilled Waterflow Interlock

A job-site-provided contact closure from

a chilled-water pump contactor, or a

flow switch, is required and will allow

unit operation if a load exists. This

feature will allow the unit to run in

conjunction with the pump system.

External Interlock

A job-site-provided contact opening

wired to this input will turn the unit off

and require a manual reset of the unit

microcomputer. This closure is typically

triggered by a job-site-provided system

such as a fire alarm.

Chilled Water Pump Control

Unit controls provide an output to

control the chilled-water pump(s). One

contact closure to the chiller is all that is

required to initiate the chilled-water

system.

Additional Features That May Be Used

(requires some optional factory-installed

hardware)

Alarm Indication Contacts

Chilled-Water Temperature Reset

Note: All wiring outside the unit is

supplied at the job site.

Integrated Comfort™

System Interface

Easy Interface to a Generic Building

Management System

Controlling the air-cooled Series R chiller

with building management systems is

state-of-the-art, yet simple. Chiller inputs

include:

• Chiller enable/disable

• Circuit enable/disable

• Chilled liquid set point

• Current limit set point

• Ice-making enable

Chiller outputs include:

• Compressor running indication

• Alarm indication (ckt 1/ckt 2)

• Maximum capacity

• Ice making

conditions, the microprocessor will

continue to optimize chiller performance

by taking the corrective action necessary

to avoid shutdown. This keeps cooling

capacity available until the problem can

be solved. Whenever possible, the chiller

is allowed to perform its function: make

chilled water. In addition,

microcomputer controls allow for more

types of protection, such as over and

under voltage! Overall, the safety

controls help keep the building or

process running and out of trouble.

Stand-alone controls

Interfacing to stand-alone units is very

simple: only a remote auto/stop for

scheduling is required for unit operation.

Signals from the chilled-water pump

contactor auxiliary, or a flow switch, are

wired to the chilled-water flow interlock.

Signals from a time clock or some other

remote device are wired to the external

auto/stop input.

Mechanical Specifications

General

Units are leak- and pressure-tested at

24.5 bars [350 psi] high side and 14 bars

[200 psi] low side, and then evacuated

and charged. Packaged units ship with a

full operating charge of oil and

refrigerant. Unit panels, structural

elements, and control boxes are

constructed of 1.5 to 3 mm [11 to 16

gauge] galvanized sheet metal and

mounted on a welded structural-steel

base. Unit panels and control boxes are

finished with baked-on powder paint,

and the structural-steel base is finished

with an air-dry paint RAL 1019.

Evaporator

The evaporator is a tube-in-shell heat

exchanger design, with internally-finned

copper tubes roller-expanded into the

tube sheet. The evaporator is designed,

tested, and stamped in accordance with

the appropriate pressure-vessel code

approval. The evaporator is designed for

a waterside working pressure of 14

bars[200 psi]. Water connections are

grooved pipe for Victaulic couplings.

Each shell includes a vent, a drain, and

fittings for temperature control sensors,

and is insulated with 19mm [3/4 inch]

Armaflex II (or equivalent) insulation

(K=0.26). Optional evaporator heaters

with thermostats are provided to protect

the evaporator from freezing at ambient

temperatures down to -25°C [-13°F].

Condenser and Fans

Air-cooled condenser coils have

aluminum fins mechanically bonded to

internally-finned seamless copper

tubing. The condenser coil has an

integral subcooling circuit. Condensers

are factory proof- and leak-tested at 35

bars [500 psi]. Direct-drive vertical-

discharge airfoil

ZephyrWing

condenser

fans are dynamically balanced. Three-

phase condenser fan motors with

permanently-lubricated ball bearings

are provided. Standard units will start

and operate from -4 to 46°C [25 to

115°F] ambient.

Compressor and Lube Oil System

The helical-rotary compressor is semi-

hermetic, direct drive, 3000 rpm, with

capacity-control slide valve, a

load/unload valve, rolling element

bearings, differential refrigerant

pressure oil pump, and oil heater. The

motor is a suction-gas-cooled,

hermetically sealed, two-pole squirrel-

cage induction motor. Oil separator and

filtration devices are provided separate

from the compressor. Check valves in

the compressor discharge and lube oil

system, and a solenoid valve in the

lube system, are provided.

Refrigeration Circuits

Each unit has two refrigerant circuits,

with one helical-rotary compressor per

circuit. Each refrigerant circuit includes

a removable-core filter drier, liquid-line

shutoff valve, liquid-line sight glass with

moisture indicator, charging port, and

an electronic expansion valve. Fully

modulating compressors and electronic

expansion valves provide variable

capacity modulation over the entire

operating range. (Optional compressor

discharge and suction service valve).

Unit Controls

All unit controls are housed in a

weather-tight enclosure, with

removable plates to allow for customer

connection of power wiring and remote

interlocks. All controls, including

sensors, are factory-mounted and -

tested prior to shipment.

Microcomputer controls provide all

control functions including startup and

shutdown, leaving-chilled-water

temperature control, compressor and

electronic expansion-valve modulation,

fan sequencing, anti-recycle logic,

automatic lead/lag compressor starting,

and load limiting. The unit control

module, utilizing the Adaptive Control™

microprocessor, automatically takes

action to avoid unit shutdown due to

abnormal operating conditions

associated with low refrigerant pressure,

high condensing pressure, and motor

current overload. Should the abnormal

operating condition continue until a

protective limit is violated, the unit will

be shut down. Unit protective functions

include loss of chilled-water flow,

evaporator freezing, loss of refrigerant,

low refrigerant pressure, high refrigerant

pressure, reverse rotation, compressor-

starting and -running overcurrent, phase

loss, phase imbalance, phase reversal,

and loss of oil flow. A digital display

indicates chilled-water set point and

leaving-chilled-water temperature as

standard, while current-limit set point,

evaporator and condenser refrigerant

pressures, and electrical information are

an option. Both standard and optional

displays can be viewed on the unit

without opening any control panel

doors. Standard power connections

include main three-phase power to the

compressors, condenser fans, and

control power transformer, and optional

connections are available for the 230

volt single-phase power for freeze

protection on the evaporator heaters.

Starters

Starters are housed in a weather-tight

enclosure with hinged doors to allow for

customer connection of power wiring.

Wye-Delta closed transition starters (33

percent of LRA inrush) are standard. An

optional Wye-Delta closed transition

starter (33 percent of LRA inrush) is

available on 400/3/50 volt units.
