30HR,HS
Model E
Reciprocating Liquid Chillers
Nominal Capacities:
70 to 160 Tons (250 to 560 kW)

Rated in accordance with
ARI Standard 590-92.

The Flotronic™ Plus Chiller Combines These Extra-Performance Features for Increased Energy Savings:
• microprocessor-based control
system
• electronic expansion valve
• increased part-load efficiency
• multiple compressors — extra capacity steps

Features/Benefits
30HR,HS units are designed
for easy installation and
maintenance
Starting with installation, these machines keep costs low. Each is
completely factory engineered and
assembled to ensure a perfectly balanced refrigeration system that can be
installed with minimal field labor.
Only external fluid and power connections need to be completed at the
jobsite to make the fluid-cooled (30HR)
units operational. Condenserless (30HS)
units require the addition of a remote
condenser.
The 30HR model is a packaged
unit complete with cooler, condensers,
compressors, controls, refrigerant
and oil charge, and internal piping and
wiring. The 30HS unit is a condenserless version of the basic 30HR,
shipped with a holding charge of refrigerant and specially designed for applications with remote fluid- or
air-cooled, or evaporative type, condensers. All the easy-rigging 30H
series chillers are extremely trim and
compact. They can pass easily
through standard doorways, and require minimal floor space on the job.

Form 30HR,HS-4PD

Additional features ensure smooth,
trouble-free operation. Compressors are mounted on heavy-duty spring
vibration isolators to minimize potentially damaging vibration transmission to the building structure. Sounddeadening mufflers dampen hot gas
pulsations. Servicing is made easy by
bolted, readily-accessible semi-hermetic
compressors that can be removed
with minimal field labor when adjustments or repairs are needed.

Flotronic™ Plus control system regulates the refrigerant cycle for optimum
efficiency
The 30HR,HS Flotronic Plus chillers
feature an electronic expansion valve
(EXV) operated by a microprocessorbased control system. The system
monitors safety functions and controls
unit capacity to maintain leaving
chilled fluid temperature. The microprocessor controls loading and unloading of compressors to match
changing cooling load requirements.
The control system consists of a
control box with a keypad and display
module, an EXV for each refrigeration circuit, and thermistors (temperature sensors) which provide analog
inputs to the microprocessor. The
control also operates a quick test program to check input and output signals to and from the microprocessor.
The 30HR,HS control system is self
contained and can operate on a
stand-alone basis if desired.

Components
The control box — All the
microprocessor-based controls required to optimize chiller operation
and protect it against unsafe conditions are contained in the control
box. This includes the processor module, relay module, EXV driver module, keypad and display module, relays,
and transformers. The box has a
hinged door for ready access.
The EXV driver — The driver positions the EXVs (based on commands
from the microprocessor) and
monitors the status of the oil and
refrigerant pressure switches.
The keypad and display module
— This module consists of a keypad with 11 function keys and 12 numeric keys (0 to 9, . , -) and an
alphanumeric 8-character liquid crystal
display. The module allows the operator to perform the following
functions:
• read and change set point
• configure unit
2

• run quick test unit checkout
• observe diagnostic information
• schedule chiller operation

Control features
Leaving fluid temperature control
with return compensation —
The rate at which the compressors
are turned on will depend on the difference between the actual leaving
fluid temperature and the set point,
the rate of change of leaving fluid
temperature, the return fluid temperature, and the number of compressor
stages on. The control is primarily
from leaving fluid temperature, and
the other factors are used as compensation. Because the control operates
from leaving fluid, the chiller is independent of cooling gpm (L/s). It is a
true droopless control.
Return temperature reset — The
control system is capable of handling leaving fluid temperature reset
based on return cooler temperature.
Because the change in temperature
through the cooler is a measure of the
building load, the return temperature
reset is in effect an average building load reset method. All sensors required to activate return reset are
standard with the unit.
Space and outdoor-air temperature reset — Space temperature
reset and outdoor-air temperature
reset allow for the reset of the leaving
fluid temperature based on an external temperature sensor. (Accessory
thermistor required.)
Energy management system reset
— Many energy management systems have the capability to transmit a
4 to 20 mA signal in proportion to
the desired leaving chilled-fluid set
point. The Flotronic Plus chillers have
the ability to recognize a proportioned signal to establish the reset
condition (field-installed components
are required).

Remote alarm — Upon initialization
of an alarm condition, an internal
contact will close to activate a signal
suitable for remote alarm activation.
Load shed (demand limit) — A
2-step demand limit can be programmed through the Flotronic Plus
controls. The control limits total power
draw of the unit by controlling the
number of steps of capacity operating
during the demand limiting period.
Pulldown control — Pulldown control is used to minimize compressor
usage and reduce the peak kW that
occurs at start-up, when the cooler
fluid temperature is very warm but the
load is small. When activated, this
feature limits the pulldown rate to
1° F (.56° C) per minute.
Unit checkout (quick test) — The
quick test feature allows determination
of the status (on or off) of various
Flotronic Plus control components (i.e.,
solenoid valves, compressors, and
unloaders). When the unit is in standby
mode, these steps will energize these
components and indicate whether
or not the components are operational.
Diagnostics — The Flotronic Plus
control system features extensive selfdiagnostics as standard. The display
will show a 2-digit diagnostic code,
and will scroll an explanation of the
code for failures that cause the unit to
shut down, terminate a reset option,
or use a default value as set point.
Time schedule — The Flotronic Plus
control system has an integral function that allows scheduling of the circulating pump and chiller operation
for up to 8 occupied/unoccupied periods per schedule, with 7 different
schedule days.

Increased part-load performance reduces operating
costs
Multiple compressors — Multiple
compressors on a refrigerant circuit further enhance part-load efficiency. This allows compressor to
operate fully loaded with 100% of
cooler and condenser surface active at

50% unit capacity, optimizing evaporating and condensing temperatures.
Since the chiller normally works at
part load for 97% of its operating
time, a substantial reduction in operating cost can be realized.
Suction cutoff unloading — Unloading on 06E compressors eliminates
unnecessary pumping of refrigerant

gases during unloader operation. This
substantially reduces part-load power
consumption.
Liquid refrigerant subcooling —
Integral subcooler uses coldest
condenser fluid to increase system
capacity without extra horsepower.

especially desirable in commercial applications where even brief equipment shutdowns can be extremely
costly.
Electronic expansion valve (EXV)
— The EXV is controlled to maintain approximately 20 F (11 C) refrigerant superheat entering the
compressor cylinders. (Ordinary thermostatic expansion valves typically
operate at 45 F [25 C] superheat

and outdoor-air temperature reset.
Unit sound enclosure panels — These panels, with fiberglass insulation, completely enclose the compressor and
condenser sections.
Gage panel package — One package is required per unit.
Package includes one suction pressure gage and one discharge pressure gage per circuit mounted on a common
panel. Each gage is equipped with a shutoff valve.
Temperature reset — Leaving fluid temperature reset accessory board may be installed in chiller to provide reset of
LCWT (leaving chilled fluid temperature) in constant fluid
flow systems. Three reset control options are: from returnfluid temperature, space temperature, and outdoor-air
temperature.
Demand limit control — This control provides 2 demand
limit steps: 1) between 50% and 100% of maximum compressor displacement; or 2) between 0% and 49% displacement. The external switching device determines when to
limit unit capacity.
Chilled Fluid Flow Switch — Although low fluid flow detection is provided by the unit internal control devices, this
accessory is available for field installation for redundant
protection.
Oil-pressure safety switch — Standard on condenserless (30HS) models, accessory on fluid-cooled (30HR) models. Switch protects compressors against loss of oil pressure
in the event of a loss of lubricating oil. One switch package
is needed for each lead compressor.

Application data
Leveling unit
To assure proper oil return, be sure that unit is level,
particularly in its major lengthwise dimension, as compressor oil return piping runs in that direction.
Determine prior to installation if any special treatment is required to assure a level installation.

Cooler fluid temperature
1. Maximum leaving chilled fluid temperature (LCWT) is
70 F (21 C). Unit can start and pull down with up to
95 F (35 C) entering fluid temperature due to MOP (maximum operating pressure) feature of the expansion valve.
For sustained operation, it is recommended that entering fluid temperature not exceed 85 F (29 C).
2. Minimum LCWT is 40 F (4 C) for standard units. Special order medium temperature brine units must be
ordered for operation with leaving fluid temperatures
in the range of 39 to 15 F (4 to −9 C). For ratings
below 40 F (4 C) LCWT, contact your local Carrier
representative.

Condenser fluid temperature
1. Maximum leaving condenser fluid temperature is
104 F (40 C) on all 30HR models (except 30HR160,
which has a maximum temperature of 120 F [49 C]).
2. Minimum entering condenser fluid temperature without
condenser flow regulation is 70 F (21 C).

made. For minimum flow rates, see Minimum Cooler and
Condenser Fluid Flow Rates and Minimum Loop Volume
table on this page. High flow rate is limited by pressure drop
that can be tolerated. If another temperature rise is used,
apply LCWT correction as given in Selection Procedure section on page 17.
Minimum cooler flow — This value (maximum cooler temperature rise) for standard units is shown in Minimum Cooler
and Condenser Fluid Flow Rates and Minimum Loop Volume table. When gpm (L/s) required is lower (or rise is
higher), follow recommendations below:
a. Multiple smaller chillers may be applied in series, each
providing a portion of the design temperature rise.
b. Chilled fluid may be recirculated to raise flow rate. However, mixed temperature entering cooler must be maintained at a minimum of at least 5° F (2.8° C) above the
leaving chilled fluid temperature.
c. Special cooler baffling is required to allow minimum flow
rate to be reduced 12%.

Application data (cont)
Minimum fluid-cooled condenser flow — This value
(maximum rise) is shown in Minimum Cooler and Condenser Fluid Flow Rates and Minimum Loop Volume table
on page 13. Condensers may be piped in series. Ensure
leaving fluid temperature does not exceed 104 F (40 C).
Variable cooler flow rates —These rates may be applied
to standard chillers. However, the unit will attempt to maintain a constant leaving chilled fluid temperature. In such cases,
minimum flow must be in excess of minimum flow given in
the Minimum Cooler and Condenser Fluid Flow Rates and
Minimum Loop Volume table, and flow rate must change
in steps of less than 10% per minute. Apply 6 gal per ton
(6.5 L per kW) fluid loop volume minimum if flow rate
changes more rapidly.
Chilled fluid loop volume — The volume in circulation
must equal or exceed 3 gal per nominal ton of cooling
(3.25 L per kW) for temperature stability and accuracy in
normal air conditioning applications. See Minimum Cooler
and Condenser Fluid Flow Rates and Minimum Loop Volume table on page 13. (For example, a 30HR100 would
require 294 gal [1112.8 L] in circulation in system loop —
see Minimum Cooler and Condenser Fluid Flow Rates and
Minimum Loop Volume table on page 13.) For process jobs
where accuracy is vital, or for operation at ambient temperature below 32 F (0° C) with low unit loading conditions,
there should be from 6 to 10 gal. per ton (6.5 to 10.8 L
per kW). To achieve this volume, it is often necessary to
install a tank in the loop. Tank should be baffled to ensure
there is no stratification, and that water (or brine) entering
tank is adequately mixed with liquid in the tank.
NOTE: Tank installation is shown below.

Fouling factor — The fouling factor used to calculate tabulated ratings was 0.00025 ft2 • hr • F/Btu (0.000044 m2 •

PERFORMANCE CORRECTIONS
1. Corrected Cooling Capacity = Rated Cooling Capacity x all correction factors.
2. Corrected Compressor Power Input = Rated Power Input x all correction factors.

Cooler and fluid-cooled condenser freeze
protection
If chiller or fluid lines are in an area where ambient conditions fall below 32 F (0° C), it is recommended that an
antifreeze solution be added to protect the unit and fluid
piping to a temperature 15° F (8.3° C) below the lowest
anticipated temperature. Corrections to performance as indicated in Capacity Correction and Selection Procedure sections on pages 15 and 17 must be applied.
Use only antifreeze solutions approved for heat exchanger
duty. Use of automotive antifreezes is not recommended
because of the fouling that can occur once their relatively
short-lived inhibitor breaks down.
If not protected with an antifreeze solution, draining cooler
and outdoor piping is recommended if system is not to be
used during freezing weather conditions.

30HS condenser requirements
1. Ensure each refrigerant circuit has its own head pressure control.
2. Condenser must provide 15° F (8.3° C) subcooling, a
maximum of 40° F (22.2° C) difference between saturated condensing temperature and outdoor ambient
temperature (to prevent overload at high ambient
temperatures), and a minimum of 20° F (11.1° C) difference (to assure subcooling).
3. Do not manifold independent refrigerant circuits into a
single condenser.
4. Condenser should not be located more than 50 ft
(15 m) below chiller to maintain subcooling.
5. Design discharge and liquid piping according to Carrier
System Design Manual.

14

Oversizing chillers

Capacity correction (antifreeze)

Oversizing chillers by more than 15% at design conditions
must be avoided as the system operating efficiency would
be adversely affected (resulting in greater and/or excessive
electrical demand and cycling of compressors). When future
expansion of equipment is anticipated, install a single chiller
to meet present load requirements, and install a second chiller
to meet the additional load demand.
It is also recommended that the installation of 2 smaller
chillers be considered where operation at minimum load is
critical. The operation of a smaller chiller loaded to a greater
percent of minimum is preferred to operating a single chiller
at or near its minimum recommended value.
Hot gas bypass should not be used as a means to allow
oversizing chillers. Hot gas bypass should be given consideration where substantial operating time is anticipated below the minimum unloading step.

If unit or fluid lines connected to the unit are in an area
where ambient temperature falls below 32 F (0° C), it is
strongly recommended that antifreeze (or other suitable brine)
be used in the chilled fluid circuit. Unit performance data
must be corrected as shown in the following example (using inhibited ethylene glycol solution):

Multiple chillers
Where chiller capacities required are greater than can be
furnished by a 30H chiller, or where standby capability is
desired, chillers may be installed in parallel. Units of equal
size help to ensure balanced fluid flows. Where a large temperature drop (. 25° F [13.9° C]) is desired, chillers may
be installed in series. Fluid temperature sensors need not
be moved for multiple chiller operation.

Part-wind start
Part-wind start is not generally required on 30H chillers due
to use of multiple small compressors allowing smaller electrical load increments, but it is available if required. Maximum instantaneous current flow (see ICF in Electrical Data
table on page 29) should be used in determining need.

Vibration isolation
Compressors are spring isolated. External vibration isolation is not generally required.

Strainers
For 30HR units, a strainer with a minimum of 20 mesh
should be installed in both the cooler and condenser fluid
inlet lines just ahead of the cooler and condenser, and as
close to the cooler and condenser as possible. For 30HS
units, this recommendation applies only to the cooler.

1. All performance data is based on:
a. Cooler water temperature rise of 10° F (5.6° C). When
more accuracy is desired, correct LCWT by amount
determined from LCWT Correction curve below before entering Performance Data tables.
b. Cooler fouling factor of .00025 (.000044) (same for

c. 10° F (5.6° C) subcooling (30HS).
d. Refrigerant 22.
LCWT CORRECTION
ENGLISH

2. When corrected LCWT is used, cooler pressure drop must
also be corrected for the new LCWT:
a. Enter Performance Data table at corrected LCWT.
By interpolation, determine corrected Capacity (tons
or kW), saturated discharge temperature (in Performance Data tables on pages 21 and 25 for 30HS
condenserless units), and kW (compressor motor power
input at rated voltage).
b. Calculate:
corrected capacity (tons) x 24
corrected gpm =
temperature rise (°F)
corrected L/s =

corrected capacity (kW) x .239
temperature rise (°C)

c. Enter Cooler Pressure Drop curve at corrected gpm
(L/s) and find pressure drop.
Where cooler water temperature rise is less than 7° F
(3.9° C), the high flow rate will normally be accomplished by excessive pressure drop. In these cases, contact your local Carrier representative for selection of a
cooler with suitable baffle spacing.
Combining 30HS units with remote condensers which
have greater than (less than) the 10° F (5.6° C)
subcooling in the ratings increases (decreases) system
capacity. To adjust capacity, multiply capacity ratings by
0.96; then adjust this result upward by 0.4% for each
degree F (0.7% for each degree C) of available
subcooling.

Two electrical power circuits are required. A separate
entrance and a terminal block are provided for each circuit. Run 6 wires to unit from disconnect switch, 3 to
each circuit.
For size 110 units, the upper value is circuit A and lower
value is circuit B. For other size units, the value given is
per electrical circuit.
For all unshaded areas: Only 1 power circuit is required,
with a single entrance. Run 3 wires to unit, to a single
terminal block.
Maximum Instantaneous Current Flow during starting (the
point in the compressor starting sequence where the
sum of the LRA for the starting compressor plus the RLA
for all running compressors is maximum). Not for wire
sizing.
Maximum allowable power input (each compressor).
Locked Rotor Amps.
Minimum Circuit Amps (for wire sizing); complies with
NEC, Section 430-24 (U.S.A. Standard).
Maximum Fuse Amps; 225% of largest compressor RLA
plus 100% of remaining compressor RLA. Size down to
the next standard fuse size.
Maximum unit power input.
Must Trip Amps (compressor circuit breaker).
National Electrical Code (U.S.A.).
Recommended dual element fuse amps; 150% of largest compressor RLA plus 100% of remaining compressor RLA. Size up to next standard fuse size.
Rated Load Amps.

*Units are suitable for use on electrical systems where voltage supplied
to the unit terminals is not below or above the listed range limits.
†Circuits and compressors are numbered from left to right when viewed
from the front of the unit.
NOTES:
1. Maximum incoming wire size for 208/230 v is as follows:
Units 070-090 have one terminal block, 3 wires, 500 kcmil.
Units 100-160 have 2 terminal blocks, 3 wires per block, 500 kcmil.
2. Maximum incoming wire size for 460 and 575 v is as follows:
Wire size maximum is 500 kcmil for units 070-160.
Units 070-120 have one terminal block, 3 wires; units 140 and 160
have 2 terminal blocks, 3 wires per block.
3. Across-the-start is standard at all voltages.
4. Control circuit requires a separate-fused (15 amp), 115-v, single-ph,
60 Hz power supply, or accessory control power transformer.
5. Control circuit MCA is 7.2 and control circuit MFA is 15.
6. Compressor motors on all units are thermally protected by overtemperature sensors in the discharge side of the compressor.
7. Maximum allowable phase imbalance is: volts 2%; amps 10%.
8. Use copper, copper-clad aluminum, or aluminum conductors for field
power wiring.

CAPACITY CONTROL STEPS

Control sequence
Standby — During unit off cycle when the RUN/STANDBY
switch is in the STANDBY position, the crankcase heaters
and the control system are energized.
NOTE: The control circuit power must be on at all times
even when the main unit power is off.
Run — When the RUN/STANDBY switch is moved from
STANDBY to RUN position, there will be a 11⁄2 minute delay while the microprocessor monitors data. If in occupied
mode, after 11⁄2 minutes the chilled fluid pump will start. If
there is a call for cooling, the first compressor will start unloaded. The first circuit to start may be circuit A or B due to
the automatic and random lead/lag feature.

Capacity control sequence
On a call for cooling, the control system starts the initial
compressor. The control will randomly select either circuit
A or B. The liquid line solenoid valve remains closed for 10
seconds after the initial compressor on that refrigeration
circuit starts (unless the compressor has run in the 15 minutes prior to the latest call for cooling). This permits a pumpout cycle at start-up to minimize refrigerant floodback to
the compressor. If the compressor has run in the 15 minutes before the call for cooling, the pumpout cycle is
eliminated.
After the pumpout, the liquid line solenoid valve and the
EXV open.
The EXV will open gradually to provide a controlled
start-up to prevent liquid floodback to the compressor. Also
during this period, the oil pressure switch will be bypassed
for one minute.
As additional cooling is required, the control system will
ramp up through the capacity steps available until the load
requirement is satisfied. As capacity steps are added, compressors are added, alternating between the lead and lag
refrigerant circuits. The speed at which capacity is increased
or decreased is controlled by the temperature deviation from
the set point and the rate of change in the chilled fluid
temperature.
When the second or lag refrigeration circuit is started,
that circuit will go through a 10-second pumpout unless the
circuit has been operating in the 15 minutes prior to this
start.
Upon load reduction, the control system will unload the
unit in the reverse order of loading until the capacity nearly
matches the load. Each time the lead compressor in a circuit is cycled off, the liquid solenoid valve and EXV will be
closed for 10 seconds prior to compressor shutdown to clear
the cooler of liquid refrigerant.
To stop unit, move the RUN/STANDBY switch to the
STANDBY position. Any refrigeration circuit that is operating at this time will continue to run for 10 seconds to
complete the pumpout cycle.
