What is the primary function of a compressor in a refrigeration system?

The primary function of a compressor in a refrigeration system is to compress the refrigerant gas. This process is vital because it increases the pressure and temperature of the refrigerant, allowing it to move through the refrigeration cycle. By compressing the gas, the compressor transforms low-pressure refrigerant vapor into high-pressure vapor, which then proceeds to the condenser, where it will release heat and change into a liquid state.

Understanding this function is crucial, as the efficiency of the entire refrigeration cycle heavily relies on the compressor’s ability to maintain the correct pressure levels. Without this compression step, the refrigerant would not be able to absorb heat effectively in the evaporator, nor release it in the condenser, leading to poor system performance.
