chiller’s piping, the start sequence is
aborted to protect the chiller.The next
chiller in the sequence is immediately
started to maintain cooling.
Energy Efficiency
Trane chiller plant automation intelligently
sequences starting of chillers to optimize
the overall chiller plant energy efficiency.
Individual chillers are designated to

Application
Considerations
Condenser WaterTemperatures
Reduced sensitivity to condenser water
startup temperatures is one major
enhancement in the newest-generation
water-cooled Series R chiller.With the
model RTHD chiller, a condenser water
control method is necessary only if the
unit starts with entering water
temperatures below 55°F (12.8°C), or
between 45°F (7.2°C) and 55°F (12.8°C),
when a temperature increase of 1°F
(0.56°C) per minute to 55°F (12.8°) is not
possible.
power input required, but the ideal
temperature for optimizing total system
power consumption will depend on the
overall system dynamics. From a system
perspective, some improvements in
chiller efficiency may be offset by the
increased tower fan and pumping costs
required to achieve the lower tower
temperatures. Contact your localTrane
systems solution provider for more
information on optimizing system
performance.
Some basic rules should be followed
whenever using these system design and
operational savings methods with the
RTHD.The proper location of the chilled
water temperature control sensor is in
the supply (outlet) water.This location
allows the building to act as a buffer, and
it assures a slowly changing return water
temperature. If there is insufficient water
volume in the system to provide an
adequate buffer, temperature control can
be lost, resulting in erratic system
operation and excessive compressor
cycling.To ensure consistent operation
and tight temperature control, the chilled
water loop should be at least two
minutes. If this recommendation cannot
be followed, and tight leaving water
temperature control is necessary, a
storage tank or larger header pipe should
be installed to increase the volume of
water in the system.
The minimum acceptable refrigerant
pressure differential between condenser
and evaporator is 23 psid.The chiller
control system will attempt to obtain and
maintain this differential at startup, but for
continuous operation a design should
maintain a 25°F (13.9°C) differential from
evaporator leaving water temperature to
condenser leaving water temperature.
When the application requires startup
temperatures below the prescribed
minimums, a variety of options are
available.To control a 2-way or 3-way
valve,Trane offers a Condenser
RegulatingValve Control option for the
CH530 controls.This option enables the
CH530 controls to send a signal for
opening and closing the valve as
necessary to maintain chiller differential
pressure.The 2-way valves are available
as a ship-with option.Tower bypass is
also a valid control method if the chiller
temperature requirements can be
maintained.
Variable Evaporator Flow and Short
EvaporatorWater Loops
For variable primary flow applications,
the rate of chilled water flow change
should not exceed 10 percent of design
per minute to maintain +/-0.5°F (0.28°C)
leaving evaporator temperature control.
For applications in which system energy
savings is most important and tight
temperature control is classified as
+/-2°F (1.1°C), up to 30 percent changes in
flow per minute are possible. Flow rates
should be maintained between the
minimum and maximum allowed for any
particular chiller configuration.
Variable evaporator flow is an energy-
saving design strategy which has quickly
gained acceptance as advances in chiller
and controls technology have made it
possible.With its linear unloading
compressor design and advanced CH530
controls, the RTHD has excellent
capability to maintain leaving water
temperature control within +/-0.5°F
(0.28°C) , even for systems with variable
evaporator flow and small chilled water
volumes.
Trane Series R chillers start and operate
successfully and reliably over a range of
load conditions with controlled entering
condenser water temperature. Reducing
the condenser water temperature is an
effective method of lowering chiller

Application
Considerations
Series Chiller Arrangements
Like series arrangements on the
Water Pumps
Another energy-saving strategy is to
design the system around chillers
arranged in series, on the evaporator,
condenser, or both.The actual savings
possible with such strategies depends on
the application dynamics and should be
researched by consulting yourTrane
Systems Solutions Representative and
applying theTrane System Analyzer
program. It is possible to operate a pair of
chillers more efficiently in a series chiller
arrangement than in a parallel
evaporator, series arrangements on the
condenser may enable savings.This
approach may allow reductions in pump
and tower installation and operating
costs. Maximizing system efficiency
requires that the designer balance
performance considerations for all
system components; the best approach
may or may not involve multiple chillers,
or series arrangement of the evaporators
and/or condensers. This ideal balance of
design integrity with installation and
operating cost considerations can also be
obtained by consulting aTrane
Where noise limitation and vibration-free
operation are important,Trane strongly
encourages the use of 1750-rpm (60 Hz),
1450-rpm (50 Hz) pumps. Specifying or
using 3600-rpm (60 Hz), 3000-rpm (50 Hz)
condenser water and chilled water
pumps must be avoided, because such
pumps may operate with objectionable
levels of noise and vibration. In addition, a
low frequency beat may occur due to the
slight difference in operating rpm
between 3600-rpm (60 Hz), 3000-rpm
(50 Hz) water pumps and Series R chiller
motors. Important Note:The chilled water
pump must not be used to stop the chiller.

higher entering-to-leaving chiller

the opportunity for lower chilled water

Selection
Procedure
Trane Series R chiller performance is
rated in accordance with the ARI
Standard 550/590-2003 Certification
Program. Chiller selection assistance and
performance information can be
obtained by using the Series R chiller
selection program, available through
localTrane sales offices.
Part Load Performance
Actual air-conditioning system loads are
frequently less than full-load design
conditions. Depending on the number of
chillers on the job and the load profile,
chillers may operate at full load a small
percentage of the time.With their
excellent part-load performance
characteristics and highly energy-efficient
operation, Series R chillers can provide
significant operating savings at these
part-load conditions.
Performance
The computerized Series R chiller
selection program provides performance
data for each possible chiller selection at
both full-load and part-load design points,
as required.
System Considerations
Part-load chiller operation is frequently
associated with reduced condenser
water temperatures. However, rather
than focusing only on the chiller, it is
important to balance these temperatures
to achieve the most efficient system
operation possible. At part-load
It should be noted that changing the
number of water passes or the water
flow rates will generally alter the
performance of a particular chiller.To
attain maximum benefit from the wide
range of chiller models and options
available, designers are encouraged to
first develop performance specifications
and then use the chiller selection program
to optimize all selections.This will help
ensure selection of the compressor-
evaporator-condenser combination that
most closely meets the job requirements.
To optimize system performance, all
selections should also be balanced with
other system components.
operation, the heat rejected to the cooling
tower is less than at full-load operation.
Part-load chiller operation is also typically
associated with reduced outside wet bulb
temperatures, resulting in improved
cooling tower performance.The net result
of reduced heat rejection and lower wet
bulb temperatures can be cooler
condenser water entering the chiller,
ultimately improving unit performance.
However, this does not improve pump or
tower efficiency.To achieve the most
efficient system operation possible, it is
best to minimize the total power draw of
the chiller, tower, and pumps, which may
not mean limiting the condenser water
temperature to what the tower can
provide.To determine specific unit and
system part-load performance for chiller
selection purposes, use the Series R
chiller computer selection program or
contact the localTrane sales office.
Fouling Factors
ARI Standard 550 includes a definition of
clean tube fouling.The recommended
standard fouling adjustments are 0.0001
hr-sq ft-deg F/Btu (0.0176 sq m-deg C/kW)
for the evaporator and 0.00025 hr-sq ft
deg F/Btu (0.044 sq m-deg C/kW) for the
condenser, from an increment of 0.0000
“clean.” Chiller specifications should be
developed using the most current
standard fouling factors.

water, including ethylene glycol and
propylene glycol— in the evaporator,
condenser or both. Chillers using media
other than water are excluded from the
ARI 550/590-2003 Certification Program,
but are rated in accordance with ARI
Standard 550/590-2003.Trane factory
performance tests are only performed
with water as the cooling and heat-
rejection media.When considering
selection of media other than water,
contact the localTrane sales office for
chiller selections and factory
Although the terms “LRA” and “expected
inrush” are often used interchangeably,
the distinction applied here is that LRA is
the rated inrush for the motor, but
expected inrush is that allowed by the
starter, based on the specific
configuration.
Selecting starters in theWye-delta or
Solid State configuration lowers
expected inrush vs. the Delta (or “across-
the-line”) configuration. A Solid State
Starter configuration lowers the
expected inrush by approximately 50
percent, whileWye-Delta lowers it by
approximately 66 percent.
performance testing information.
Fluid media other than water lowers the
heat transfer coefficient, and therefore
reduces chiller performance. In general, it
is good practice to hold the percent glycol
added to within the minimum allowed by
theTrane selection program, based on
either (a) unit operating temperatures, or
(b) the operating temperatures the
evaporator or condenser water will
experience under its full range of
conditions. Adding more glycol than
required for the specific application is
equivalent to selecting a less efficient
chiller. Lower-viscosity glycols such as
ethylene will have less adverse impact
on chiller performance than higher-
viscosity glycols such as propylene.
The RLA is based on the motor’s
performance when reaching full rated
horsepower.The kW rating of the motor
will equal or exceed the kW requirement
indicated by the Series R computer
selection program at design conditions. If
motor kW draw at design conditions is
less than the kW rating of the motor, the
RLA at design conditions is determined
by multiplying the motor RLA (at the
desired voltage) by this ratio: design kW/
motor kW rating.This calculation is
performed within the Series R chiller
computer selection program, making
RLA available as part of the design
predictions. Predicted values include
power factor variation from point to point.
Evaporator and Condenser Pressure
Drop
Pressure drop data is determined by the
Series R chiller computer selection
program available through localTrane
sales offices.
A voltage utilization range is tabulated for
each voltage listed. Series R chillers are
designed to operate satisfactorily over a
utilization range of 10 percent of the
standard design voltages: (a) 200V, 230V,
380V, 460V, and 575V for 60 Hertz, 3-
phase, and (b) 380V, 400V,

The display will identify the fault, indicate
date, time, and operating mode at time of
occurrence, and provide type of reset
required and a help message.The
diagnostic history will display the last ten
diagnostics with their times and dates of
occurrence.
Exposed metal surfaces are painted with
air-dry beige, direct-to-metal, single-
component paint. Each unit ships with full
operating charges of refrigerant and oil.
Molded neoprene isolation pads are
supplied for placement under all support
points. Startup and operator instruction
by factory-trained service personnel are
included.
available with grooved connections (150
or 300 psig waterside). All connections
may be either right- or left-handed.
Waterside shall be hydrostatically tested
at 1.5X design working pressure.
Refrigerant Circuit
An electronically controlled expansion
valve is provided to maintain proper
refrigerant flow.
Clear Language Display Panel
Factory-mounted to the control panel
door, the operator interface has an LCD
touch-screen display for operator input
and information output.This interface
provides access to the following
information: evaporator report,
condenser report, compressor report,
ASHRAE Guideline 3 report, operator
settings, service settings, service tests,
and diagnostics. All diagnostics and
messages are displayed in “clear
language.”
Compressor and Motor
Unit Controls (CH530)
The unit is equipped with a semi-
hermetic, direct-drive, 3600-rpm (3000
rpm @ 50 Hz) rotary compressor that
includes a capacity control slide valve, oil
sump heater, and differential pressure
refrigerant oil flow system. Four
pressure-lubricated, rolling-element
bearing groups support the rotating
assembly.
The microprocessor-based control panel
is factory-installed and factory-tested.The
control system is powered by a control
power transformer, and will load and
unload the chiller through adjustment of
the compressor slide valve.
Microprocessor-based chilled water reset
based on return water is standard.
The CH530 microprocessor automatically
acts to prevent unit shutdown due to
abnormal operating conditions
associated with low evaporator
refrigerant temperature, high condensing
temperature, and/or motor current
overload. If an abnormal operating
condition continues and the protective
limit is reached, the machine should shut
down.
The motor is a suction gas-cooled,
hermetically sealed, two-pole, squirrel
cage induction-type.
Data contained in available reports
includes:
•Water and air temperatures
• Refrigerant levels and temperatures
• Oil pressure
• Flow switch status
• EXV position
• Head pressure control command
• Compressor starts and run-time
• Line phase percent RLA, amps, and
volts
Unit-Mounted Starter
The unit is supplied with a NEMA 1 type
enclosure with top power-wiring access
and three-phase, solid state overload
protection.The starter is available in a
Wye-Delta configuration, factory-
mounted and fully pre-wired to the
compressor motor and control panel. A
factory-installed, factory-wired 600VA
control power transformer provides all
unit control power (120VAC secondary)
and CH530 module power (24VAC
secondary). Optional starter features
include circuit breakers, ground fault
circuit breakers, and mechanical, non-
fused disconnects.
The panel includes machine protection
shutdown requiring manual reset for the
following conditions:
• low evaporator refrigerant temperature
and pressure
• high condenser refrigerant pressure
• low oil flow
• critical sensor or detection circuit faults
• motor current overload
• high compressor discharge temperature
• lost communication between modules
• electrical distribution faults: phase loss,
phase imbalance, or phase reversal
• external and local emergency stop
• starter transition failure
All necessary settings and setpoints are
programmed into the microprocessor-
based controller via the operator
interface.The controller is capable of
receiving signals contemporaneously
from a variety of control sources, in any
combination, and priority order of control
sources can be programmed.The control
source with priority determines active
setpoints via the signal it sends to the
control panel. Control sources may be:
• the local operator interface (standard)
• a hard-wired 4-20 mA or 2-10VDC
signal from an external source
(interface optional; control source not
supplied)
Evaporator and Condenser
Shells are carbon steel plate.The
evaporator and condenser are designed,
tested, and stamped in accordance with
ASME Code for refrigerant-side/
working-side pressure of 200 psig.
The panel also includes machine
protection shutdown with automatic
reset for the following correctable
conditions:
• momentary power loss
• under/over voltage
All tube sheets are made of carbon steel;
tubes are mechanically expanded into
tube sheets and mechanically fastened to
tube supports. Evaporator tubes are 1.0-
inch (25.4 mm) diameter and condenser
tubes are 0.75-inch
(19.05 mm) diameter. Both types can be
individually replaced. Standard tubes are
externally finned, internally enhanced
seamless copper with lands at all tube
sheets.
• Generic BAS (optional points; control
source not supplied)
• LonTalk LCI-C (interface optional; control
source not supplied)
• loss of evaporator or condenser water
flow
•TraneTracer Summit™ system (interface
optional)
When a fault is detected, the control
system conducts more than 100
diagnostic checks and displays results.
