Refrigeration principle of finned evaporator

The refrigeration compressor of the refrigerator is mainly used to compress low-pressure steam into high-pressure steam, thereby reducing the volume of the steam and increasing the pressure.
The compressor sucks the low-pressure steam of the working medium of the evaporator - the pressure enters the condenser, the cold high-pressure liquid is condensed in the condenser - the throttle valve throttles, and becomes a low-pressure liquid - enters the evaporator - the heat of the evaporator evaporates and becomes a low-pressure steam - into the inlet of the evaporator. Thus completing the refrigeration cycle.
