REFRIGERATION SYSTEM


Refrigerant Cycle







REFRIGERANT FLOW
The refrigerant flows in the standard pattern, that is, through the compressor, the condenser with liquid tank, through the front evaporator, and back to the compressor. The refrigerant evaporation through the evaporator coil is controlled by the front externally equalized expansion valve, located inside the front evaporator case.

FREEZE PROTECTION
The compressor cycles on and off to maintain the evaporator temperature within a specified range. When the evaporator coil temperature falls below a specified point, the intake sensor interrupts the compressor operation. When the evaporator coil temperature rises above the specification, the intake sensor allows compressor operation.
