Evaporator - Receives the liquid refrigerant. Condenser - Facilitates heat transfer. Expansion valve - regulates refrigerant flow into the evaporator. Compressor - A pump that pressurizes refrigerant. The cold side of an air conditioner contains the evaporator and a fan that blows air over the chilled coils and into the room.

REFRIGERATION CYCLE

REFRIGERATION CYCLE

EVAPORATOR The evaporator is a heat exchanger where the expanded cold gas exchanges heat with the area being cooled. (This area may be a refrigerator, your living room, or a meat locker. The fluid generally is just normal air.) CARNOT CYCLE All refrigerators work on a combination of processes, cycles, which achieve
