What is the purpose of a compressor in a refrigeration system?

The purpose of a compressor in a refrigeration system is to compress the refrigerant gas. In this process, the compressor takes in low-pressure refrigerant vapor from the evaporator and provides it with energy, which causes the gas to be compressed into a high-pressure state. This increase in pressure raises the temperature of the refrigerant, preparing it for the next stage in the refrigeration cycle, which is condensation.

By increasing the pressure and temperature, the compressor facilitates the flow of the refrigerant through the system, allowing it to effectively absorb heat from the area to be cooled and then release that heat to the outside environment through the condenser. This is a crucial function, as it enables the refrigeration cycle to continue, maintaining efficient cooling. Understanding the role of the compressor is fundamental in evaluating the overall operation of any refrigeration system.
