General Description

REFRIGERATION CYCLE

1. The compressor discharges high temperature and high pressure refrigerant that contains 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.

4. By the expansion valve, the liquid refrigerant changes into 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 change into the gaseous refrigerant in the evaporator and only heat-laden gaseous refrigerant is drawn into the compressor. Then, the process is repeated again.
