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

In a refrigeration cycle, the primary function of a compressor is to pump the refrigerant. The compressor takes in low-pressure refrigerant gas from the evaporator and compresses it to a higher pressure and temperature. This process is critical because it allows the refrigerant to move through the system, facilitating the transfer of heat from inside a space to the outside environment.

By increasing the pressure, the compressor enables the refrigerant to condense into a liquid as it flows through the condenser. The pumping action also creates a continuous flow of refrigerant, which is essential for the operation of the entire refrigeration system.

Understanding this fundamental role highlights the importance of the compressor as the heart of the refrigeration cycle, ensuring that the refrigerant circulates effectively and that the heat exchange processes can occur optimally.
