Introduction
Trane is a leader in the air-cooled chillers marketplace,
thanks to excellence in design and manufacturing.
This tradition of excellence is present in the Conquest
air-cooled scroll compressor chillers range, a new
generation of chillers and heat pumps, providing
capacities from 42-160 kW.
Trane Quality
Trane is the designer and manufacturer of the core
components applying modern market standards
of quality in the finishing, a rigourous testing and
manufacturing plan, a powerful service portfolio
supporting the life cycle of the equipment.
Useful Efficiency
The cooling only chillers, model CGAX, are rated Class B
(EER at full load at Eurovent conditions) and optimized
for operation at seasonal part load efficiency (ESEER)
to maximize energy savings during real life building
demand, across all seasons.
The heat pump version, model CXAX, has been
optimized in the same way. Full Load COP is class B
as per Eurovent standard as well, while the part load
efficiency ratio SCOP is compliant with Ecodesign
directive.
Acoustic Package
Two acoustical package options are available:
• Standard Noise (SN), with an average sound power of
Lw 86 dB(A)
• Low Noise (LN), for sensitive environments with a
sound reduction of an additional -6 dB(A)
The acoustical package does not bring any degradation
on the performances: cooling capacity, operating map,
or efficiency.
Smart Chillers
• The operating map of the chiller, allows in cooling
mode, operation between -18°C up to 46°C ambient air
temperature.
• In heating mode, CXAX units can deliver 40°C hot
water, down to -15°C ambient air temperature.
• For industrial applications, with evaporator leaving
water temperature down to -12°C is Ecodesign
compliant (SEPR medium temperature > 2,8).
• The low profile of the Conquest units allows easy
integration in buildings, thanks to the 1,5 m of height
on most of the units.
• A plug & play integration is supported by the option of
Hydraulic Module (with or without buffer tank).
• Chillers are provided with a Smart Controller and
a new generation interface, the DeluxeTouch Display.
• Full integrability capability thanks to available
communication protocols: Modbus, BACnet, LonTalk

Microchannel condensing coils on cooling-
only units
Conquest chillers are equipped with microchannel
condensing coils allowing excellent heat transfer and a
dramatic improvement of corrosion resistance versus
conventional tubes in fins coils. Microchannel coils are
100% aluminum, therefore avoiding galvanic corrosion
which can occur on conventional condensers made with
copper tubes and aluminum fins. Microchannel coils are
also well adapted for dirty environment thanks to their
small thickness and fins profile.
Heat pump units coils
The condenser coil is made of aluminum fins
mechanically bonded to seamless copper tubing and
includes integral subcooling circuit.The coils are factory
leak tested at 5 Mpa. If the unit is to be installed in a
corrosive environment, aluminum fins can be pre-coated
with epoxy (optional), with minimum thickness of 8µm,
in order to withstand 1000 hours of salt spray test
according to ISO 9227.
Electronic Expansion Valve
Electronic expansion valve enables tight chilled water
temperature control and low superheat, resulting in
more efficient full-load and part-load operation.
Application versatility

Application Considerations
Certain applications contraints should be considered
when sizing, selecting and installing Conquest air-
cooled Scroll chillers. Unit and system reliability often
depend on proper and complete compliance with those
considerations.
Unit Size
Unit oversizing is often not recommended since erratic
unit operation and excessive compressor cycling are
often a direct result of an oversized chiller. If oversizing
is desired, consider the alternative of multiple units,
splitting the total capacity.
Water Treatment
The use of untreated or improperly treated water in
chillers may result in scaling, erosion, corrosion, and
algae or slime buildup.This will adversely affect heat
transfer between the water and system components.
Proper water treatment must be determined locally
and depends on the type of system and local water
characteristics.
Neither salty nor brackish water is recommend for use
inTrane air-cooled Conquest chiller. Usage of either
will lead to a shortened life.Trane encourages the
employment of a qualified water treatment specialist,
familiar with local water conditions, to assist in the
establishment of a proper water treatment program.
Foreign matter in the chilled water system can also
increase pressure drop and, consequently, reduce water
flow. For this reason it is important to thoroughly flush
all water piping to the unit before making the final piping
connections to the unit.
Effect of the altitude on the cooling capacity
At elevations substantially above sea level, the
decreased air density will decrease condenser capacity
and, therefore, unit capacity and efficiency.
Water flow limits
The minimum water flow rates are given in the General
Data section of this catalog. Evaporator flow rates below
the tabulated values will result in laminar flow causing
freeze-up problems,scaling, stratification and poor
control.The maximum evaporator water flow rate is also
given. Flow rates exceeding those listed may result in
very high pressure drop across the evaporator.
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 Conquest chiller evaporator. A simple
piping change can alleviate this problem. For example:
a plastic injection molding process requires 5.0 l/s of
10°C water and returns that water at 15.6°C. The selected
chiller can operate at these temperatures, but has a
minimum flow rate of 6.6 l/s.The system layout in
Figure 7 can satisfy the process.
L = Load
P = Pump
Flow Proving
Trane provides a factory-installed water flow switch
monitored by chilller controller CH535 which protects the
chiller from operating in loss of flow conditions.
Leaving Water Temperature Limits
Trane air-cooled Conquest chillers have two distinct
leaving water categories:
• standard, with a leaving solution range of 5.5 to 18°C
• low temperature process cooling, with leaving solution
range of -12 to 18°C
Since the leaving solution temperature below 5.5°C
results in suction temperature at or below the freezing
point of water, a glycol solution is required for all low
temperature.
Consult your localTrane sales engineer for applications
or selections involving low temperature.The maximum
water temperature that can be circulated through the
CGAX evaporator when the unit is not operating is
51.7°C. For the model CXAX the water temperature
limit is 60°C. Evaporator damage may result above this
temperature.

Application Considerations
Supply Water Temperature Drop
Full load chilled water temperature drops from 3.3 °C to
10°C 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 at full load
conditions are beyond the optimum range for control
and may adversely affect the microcomputer’s ability to
maintain an acceptable supply water temperature range.
Furthermore, full load temperature drops of less than
3.3°C may result in inadequate refrigerant superheat
which is critical to long term efficient and reliable
operation.
Sufficient superheat is always a primary concern in
any refrigerant system and is especially important in a
packaged chiller where the evaporator is closely coupled
to the compressor.
Parameters which influence the water temperature
stability:
• Ambient temperature and water temperature (modify
cooling capacity)
• Number of capacity steps
• Minimum time between starts of a compressor
• Control dead band
• Water loop volume
• Load fluctuations
• Fluid type or percentage of glycol
Typical Water Piping
All building water piping must be flushed prior to
making final connections to the chiller. To reduce
heat loss and prevent condensation, insulation
should be applied. Expansion tanks are also usually
required so that chilled water volume changes can be
accommodated.
Avoidance of Short Water Loops
Adequate chilled water system water volume is an
important system design parameter because it provides
for stable chilled water temperature control and helps
limit unacceptable short cycling of chiller compressors.
The Conquest Air Cooled chiller’s temperature control
sensor is located in the supply (outlet) water connection
or pipe.This location allows the building to act as a
buffer to slow the rate of change of the system water
temperature. If there is not a sufficient volume of water
in the system to provide an adequate buffer, temperature
control can suffer, resulting in erratic system operation
and excessive compressor cycling.
Typically, a two-minute water loop circulation time is
sufficient to prevent short water loop issues.Therefore,
as a guideline, ensure the volume of water in the chilled
water loop equals or exceeds two times the evaporator
flow rate. For systems with a rapidly changing load
profile the amount of volume should be increased.
If the installed system volume does not meet the above
recommendations, the following items should be given
careful consideration to increase the volume of water in
the system and, therefore, reduce the rate of change of
the return water temperature.
• A volume buffer tank located in the return water piping.
• Larger system supply and return header piping (which
also reduces system pressure drop and pump energy
use).
An optional factory-installed buffer tank is designed
to meet the minimum two minute loop time without
additional job site piping.The buffer tank can also be
used on jobs that already meet or exceed the minimum
loop time to further reduce the potential for compressor
cycling, increasing the compressor life span, and
reducing system temperature fluctuations.

CG-PRC026C-GB 9
Application Considerations
Minimum water volume for a process application
If a chiller is attached to an on/off load such as a
process load, it may be difficult for the controller to
respond quickly enough to the very rapid change in
return solution temperature if the system has only the
minimum water volume recommended. Such systems
may cause chiller low temperature safety trips or in the
extreme case evaporator freezing. In this case, it may
be necessary to add or increase the size of the mixing
tank in the return line or consider the optional factory-
installed buffer tank with the chiller. Some guidance on
calculating the minimum volume necessary for proper
Scroll Compressors Chillers operation are given here,
through a simplified formula, which does not take in
account variations on chiller efficiency, compressor
sequencing, evaporator inlet/outlet temperature.
Minimum recommendable volume on the hydraulic loop
V= Cc * T / (Sh * Db) where:
Cc * T = V * Db * Sh
V= Volume of the loop (l)
Cc = Cooling Capacity of the chiller biggest Stage (kW)
T= CompressorTime (min running time (s))
Db = Dead Band (K)
Sh = Brine Specific heat (kJ.K-1.kg-1)
Multiple Unit Operation
Whenever two or more units are used on one chilled
water loop,Trane recommends that their operation be
coordinated with a higher level system controller for
best system efficiency and reliability.TheTraneTracer
system has advanced chilled plant control capabilities
designed to provide such operation.

Unit Placement
Setting The Unit
A base or foundation is not required if the selected unit
location is level and strong enough to support the unit’s
operating weight (see “Weights” section of this catalog).
For a detailed discussion of base and foundation
construction, refer to the sound engineering bulletin or
the unit IOM. Manuals are available through the local
Trane office.
HVAC equipment must be located to minimize sound
and vibration transmission to the occupied spaces of
the building structure it serves. If the equipment must
be located in close proximity to a building, it should be
placed next to an unoccupied space such as a storage
room, mechanical room, etc. It is not recommended to
locate the equipment near occupied, sound sensitive
areas of the building or near windows. Locating the
equipment away from structures will also prevent sound
reflection, which can increase sound levels at property
lines or other sensitive points.
Isolation and Sound Emission
Structurally transmitted sound can be reduced
by elastomeric vibration eliminators. Elastomeric
isolators are generally effective in reducing vibratory
noise generated by compressors, and therefore, are
recommended for sound sensitive installations. An
acoustical engineer should always be consulted in
critical situations.
Figure 9 - Installation example
For maximum isolation effect, water lines and electrical
conduit should also be isolated. Wall sleeves and rubber
isolated piping hangers can be used to reduce the sound
transmitted through water piping. To reduce the sound
transmitted through electrical conduit, use flexible
electrical conduit.
Local codes on sound emissions should always be
considered. Since the environment in which a sound
source is located affects sound pressure, unit placement
must be carefully evaluated. Sound power levels for
chillers are available on request.
Servicing
Adequate clearance for evaporator and compressor
servicing should be provided. Recommended minimum
space envelopes for servicing are located in the
dimensional data section and can serve as a guideline
for providing adequate clearance.The minimum space
envelopes also allow for control panel door swing
and routine maintenance requirements. Local code
requirements may take precedence.
Unit Location
General
Unobstructed flow of condenser air is essential to
maintain chiller capacity and operating efficiency. When
determining unit placement, careful consideration
must be given to assure a sufficient flow of air across
the condenser heat transfer surface.Two detrimental
conditions are possible and must be avoided: warm air
recirculation and coil starvation. Air recirculation occurs
when discharge air from the condenser fans is recycled
back to the condenser coil inlet. Coil starvation occurs
when free airflow to the condenser is restricted.
Condenser coils and fan discharge must be kept free of
snow or other obstructions to permit adequate airflow
for satisfactory unit operation. Debris, trash, supplies,
etc., should not be allowed to accumulate in the vicinity
of the air-cooled chiller. Supply air movement may draw
debris into the condenser coil, blocking spaces between
coil fins and causing coil starvation.
Both warm air recirculation and coil starvation cause
reductions in unit efficiency and capacity because of
the higher head pressures associated with them.The
air-cooled Conquest chiller offers an advantage over
competitive equipment in these situations. Operation is
minimally affected in many restricted air flow situations
due to its advanced chiller controller.
Microprocessor which has the ability to understand the
operating environment of the chiller and adapt to it by
first optimizing its performance and then staying on
line through abnormal conditions. For example, high
ambient temperatures combined with a restricted air
flow situation will generally not cause the air-cooled
model CGAX chiller to shut down. Other chillers would
typically shut down on a high pressure nuisance cut-out
in these conditions.
Cross winds, those perpendicular to the condenser, tend
to aid efficient operation in warmer ambient conditions.
However, they tend to be detrimental to operation
in lower ambients due to the accompanying loss of
adequate head pressure. Special consideration should
be given to low ambient units. As a result, it is advisable
to protect air-cooled chillers from continuous direct
winds exceeding 4.5 m/s in low ambient conditions.
Chiled water piping
should be supported.

CG-PRC026C-GB 11
Unit Placement
Provide Sufficient Unit-to-Unit Clearance
Units should be separated from each other by sufficient
distance to prevent warm air recirculation or coil
starvation. Doubling the recommended single unit
air-cooled chiller clearances will generally prove to be
adequate.
Walled Enclosure Installations
When the unit is placed in an enclosure or small
depression, the top of the surrounding walls should be
no higher than the top of the fans.The chiller should be
completely open above the fandeck.There should be no
roof or structure covering the top of the chiller. Ducting
individual fans is not recommended.
