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

The primary function of a compressor in refrigeration systems is to compress refrigerant gas to increase its pressure and temperature. In refrigeration cycles, the compressor plays a critical role in transforming low-pressure refrigerant vapor into high-pressure vapor. This process is essential for the refrigerant to flow through the system effectively.

When the compressor compresses the refrigerant, it raises the pressure, which in turn increases the temperature of the gas. This higher-pressure, higher-temperature refrigerant then moves to the condenser, where it releases heat and condenses into a liquid before entering the expansion valve. Thus, the compressor not only facilitates the movement of refrigerant throughout the system but also ensures that the thermodynamic cycle of heat exchange is maintained, making it a vital component for the overall efficiency and functionality of refrigeration systems.
