SYSTEM DESCRIPTION
REFRIGERATION SYSTEM
Refrigerant Cycle
INFOID:0000000006163099
REFRIGERANT FLOW
The refrigerant flows in the standard pattern, that is, through the compressor, the condenser with liquid tank,
through the evaporator, and back to the compressor. The refrigerant evaporation through the evaporator coils
are controlled by externally equalized expansion valve, located inside the evaporator case.
Refrigerant System Protection
INFOID:0000000006163100
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

REFRIGERATION SYSTEM
pressure side detected by refrigerant pressure sensor is over about 2,746 kPa (28 kg/cm
2
, 398 psi), or below
about 120 kPa (1.22 kg/cm
2
, 17.4 psi).
PRESSURE RELIEF VALVE
The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compressor.
When the pressure of refrigerant in the system increases to an abnormal level [more than 2,990 kPa (30.5 kg/
cm
2
, 433.6 psi)], the release port on the pressure relief valve automatically opens and releases refrigerant into
the atmosphere.
