Refrigerator Compressor

The refrigerator compressor is one of the four main components that makes the refrigerator work. The compressor’s job is to compress and control the flow of refrigerant. The compressor receives low pressure gas from the evaporator and converts it into high pressure gas. As the gas is compressed and the pressure increases, the temperature increases.
The compressor is the "heart" of a refrigerator. It circulates the refrigerant throughout the system and adds pressure to the warm part of the circuit, and makes the refrigerant hot. It`s similar to when you are pumping air into a bicycle tube - you can sense a heat increase in the pump while you compress the air.
