Operating Principles
This section contains an overview of the operation of
CGAX and CXAX air cooled chillers, microprocessor
based unit control modules Tracer™ Symbio800 control
systems.
Note: To ensure proper diagnosis and repair, contact a
qualified service organization if a problem should occur.
General
CGAX and CXAX chillers are scroll compressor, single or
dual circuit air-cooled chillers. These units are equipped
with unit-mounted starter/control panels and operate
with R410A refrigerant.
The basic components on the CGAX/CXAX are:
• Unit-mounted panel containing starter and unit
controller
• Scroll compressors
• Brazed plate evaporator
• Air-cooled condenser with sub-cooler
• Electronic expansion valve
• Related interconnecting piping
Refrigerant Cycle
Refrigerant cycle is similar to other Trane Scroll
compressor chillers. Conquest chillers use brazed plate
evaporator and air-cooled condenser. Compressors
use suction gas cooled motors and an oil management
system to provide almost oil-free refrigerant to the
condenser and evaporator for maximum heat transfer
while lubricating and sealing compressor rotors and
bearings. The lubrication system helps to assure long
compressor life and contributes to quite operation.
Liquid refrigerant coming from the condenser coils,
are metered into the brazed plate evaporator using an
electronic expansion valve to maximize chiller efciency
at full and part load operation.
Chillers are equipped with a unit-mounted starter and
control panel. Microprocessor based unit control module
Tracer™ Symbio800 controller provides accurate chilled
water control monitoring, protection and limit functions.
If problems occurs the unit controller provide diagnostic
messages to help the operator in troubleshooting.
