REFRIGERATION SYSTEM HA-17 < FUNCTION DIAGNOSIS > C D E F G H J K L M A B HA N O P FUNCTION DIAGNOSIS REFRIGERATION SYSTEM Refrigerant Cycle INFOID:0000000005147642 REFRIGERANT FLOW The refrigerant flows in the standard pattern, that is, through the compressor, the condenser with liquid tank, through the front and rear evaporators, and back to the compressor. The refrigerant evaporation through the evaporator coils are controlled by front and rear externally equalized expansion valves, located inside the front and rear evaporator cases. Refrigerant System Protection INFOID:0000000005147643 REFRIGERANT PRESSURE SENSOR The refrigerant system is protected against excessively high or low pressures by the refrigerant pressure sen- sor, located on the condenser. If the system pressure rises above or falls below the specifications, the refriger- ant pressure sensor detects the pressure inside the refrigerant line and sends a voltage signal to the ECM. The ECM de-energizes the A/C relay to disengage the magnetic compressor clutch when pressure on the high WJIA1342E |
