Features andBenefits

• The rotating part is made by high-

strength cast iron. It forms a closed

compression chamber, prevents the

deformation and the leakage, ensures

the high performance and prevents the

compressor from the hammering.

• 3-D scroll compressor has been

researched and improved for more than

20 years. The measurements and the

performance of more than 400,000 hours

have proved its high performance and

outstanding quality.

Outstanding and Reliable

Performance

• High part load efficiency, reduce power

consumption and save energy.

• Low sound level, applicable to high

standard requirement buildings.

• Chillers are tested before shipment,

ensure the safety and the reliability.

• Able to operating within 43˚C ambient

temperature.

• Specially designed electrical control

panel and colored cables for easier

connection. An attached strainer can be

installed on site by customers to prevent

the evaporator from clogging. Removable

panels make it easy to install, adjust and

maintain.

• The structure is compact and low in

height. It can be installed with clearance

of 1 meter to wall and chiller design

blends in well with most building

environment.

• Water flow protection system is included

as a standard component thus eliminating

installation of water switches on site.

• The dry contacts are provided by the

chiller to control the chilled water pump.

High efficiency 3-D Scroll

Compressor

The compressor of the chiller is 3-D scroll

compressor, which combines the 25

patents of "TRANE" together with

advantages of:

• Compared with the reciprocating

compressor of the same capacity, 3-D

scroll compressor reduced 64%

components, thus decreases frictions

and improves reliability and efficiency.

• The compressor torque variation is 30%

that of the reciprocating compressor with

the same capacity, thus reduces

vibrations and noise.

• The motor is cooled by the suction gas,

thus prolongs the service life, improves

the efficiency.

• Enclosed design, free of maintenance.

Features andBenefits

Powerful Microprocessor

SMM

• Leaving chilled water temperature

control

A water temperature sensor is fixed at

the outlet of evaporator. With this

temperature information, the SMM

module uses proportional integral

differential (PID) algorithm to predict and

control the on/off combinations of

sequencing compressors, thus controlling

the leaving chilled water temperature.

• Condensing pressure control

The SMM module can control the number

of operating condenser fans to achieve

the best of coefficient of performance

(COP), and to avoid the frequent chiller

shut down caused by the high/low

pressure protection.

• Performance optimization

In order to reduce electricity consumption,

the SMM module can automatically adjust

the chilled water setpoint in relation to

the outdoor temperature.

• Operator interface

The SMM module inc ludes a

communication interface with a liquid

crystal display. It helps technician to

access chiller operating conditions and

diagnosis information, thus making

operation and maintenance much easier.

• Remote control

The dry contacts and the analog inputs

are provided by the SMM module to

remote control the start/stop of the chiller

and to adjust the chil led water

temperature setpoint.

• Connection to the Building

Management System (BMS)

By option of TCI-S Communication Card

and serial communication cables, the

SMM module can communicate with the

professional BMS and in turn put the

chiller system under BMS group control,

so as to achieve operation and

maintenance convenience.

Environmentally Responsible

R407C Refrigerant

Both Aquastream cooling-only and

reversible chillers have been optimized

for exclusive use of chlorine-free R407C

refrigerant. Aquastream chillers operate

with a refrigerant that has a future and

complies with current and upcoming

environmental regulations.

Value Added Hydraulic

Module (Optional for models

040 to 080)

Only a main power supply & water

connections are necessary, the rest is

in the "box" such as pump, expansion

tank, valves, relief valve, water make-

up system etc which reduces customer's

installation time. TRANE offers this

hassle-free package that also saves

installation, operational and maintenance

costs.

Additional Functions

• Delay protection prevents the

compressors from frequent start/stop.

• Self-start after power off

• Self-balance the operation time of each

compressor

• Control the chilled water pump operation

• Prevent the evaporator from frosting

• Safety and protection operation

Standard Components

• Vibration proof rubber pad

• Y-type water strainer

• Differential pressure type water flow

switch

• Remote on / off switch

Options

• Condenser protecting grille

• Main power disconnect switch

• Compressor sound attenuator

• Factory installed low ambient

temperature kit.

• Integrated hydraulic module (Only for

040, 050, 060, 080 models)

Factory Testing and Quality

Assurance

• All chillers are subject to the strict

performance tests before shipment

• The Quality Management System

applied by "TRANE" factories in China

has been assessed and approved to ISO

9001 by professional organization.

The cooling capacity table in the chapter

of "general data" represents of typical

leaving water temperature under the

following conditions:

• Fouling factor = 0.086m2 • ˚C/kW

• Evaporator entering and leaving water

temperature difference between 4~8˚C.

Take CXAH as an example, the following

design conditions should be determined:

Cooling:

1) System cooling load(kW)

2) Chilled water leaving temperature(˚C)

3) Ambient temperature(˚C)

Heating

1) hot water leaving temperature(˚C)

2) ambient temperature(˚C), dry bulb(DB)

and wet bulb(WB) temperature.

Calculate the water flow rate with the

following formula:

Flow rate(L/s) = 0.239xload(kW)/entering and

leaving water temperature difference (˚C)

Case study for selection procedure

Cooling Conditiong:

Condition:

1) system load: 120 kW

2) chilled water leaving temperature:+7˚C

3) chilled water entering temperature:+12˚C

4) ambient temperature: 35˚C

1. Select model

According to the cooling capacity chart,

model CXAH050 can provide 125 kW

cooling capacity, and 39.5 kW input

power is required.

2. Water flow rate

Flow rate(L/s)=125x0.239/(12-7)=5.97(L/s)

3. Water pressure drop across evaporator

According to the water pressure drop

chart, when the flow rate is 5.97 L/s, the

pressure drop is 50 kPa for CXAH050.

Heating Condition:

Condition:

1) hot water leaving temperature 45˚C

2) ambient temperature: 7˚C(DB), 6˚C(WB)

1. According to the heating capacity

chart, model CXAH050 can provide 133

kW heating capacity, and 43 kW input

power is required.

2. The entering and leaving water

temperature difference can be calculated

by the following formula:

hot water entering and leaving

temperature difference= heating capacity

(133kW)x0.239/ water flow rate(5.97 L/s)

= 5.32˚C.
