4. The liquid refrigerant is changed by the expansion valve into a low temperature, low pressure liquid
and gaseous mixture.
5. This cold and foggy refrigerant flows to the evaporator. Vaporizing the liquid in the evaporator, the
heat from the warm air stream passing through the evaporator core is transferred to the refrigerant. All
the liquid is changed into the gaseous refrigerant in the evaporator and only heat–laden gaseous
refrigerant is drawn into the compressor. Then the process is repeated again.

GENERAL DESCRIPTION

REFRIGERATION CYCLE

1. The compressor discharges high temperature and high
pressure refrigerant containing the heat absorbed from
the evaporator plus the heat created by the compressor
in a discharge stroke.
2. This gaseous refrigerant flows into the condenser. In the
condenser, the gaseous refrigerant condenses into liquid
refrigerant.
3. This liquid refrigerant flows into the receiver which stores
and filters the liquid refrigerant till the evaporator requires
the refrigerant.
