What purpose does a refrigerator’s compressor serve?

A refrigerator compressor is the center of the refrigeration cycle. It works as a pump to control the circulation of the refrigerant, and it adds pressure to the refrigerant, heating it up. The compressor also draws vapor away from the evaporator to maintain a lower pressure and lower temperature before sending it to the condenser.
