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

The compressor in a refrigeration system plays a crucial role in the circulation and transformation of the refrigerant. Its primary function is to increase both the pressure and temperature of the refrigerant vapor. When the refrigerant enters the compressor, it is in a low-pressure gaseous state. The compressor compresses this gas, significantly raising its pressure and, as a result, its temperature.

This elevated pressure and temperature are necessary for the refrigerant to flow through the condenser, where it can release heat absorbed from the evaporator and transform into a liquid. Therefore, the compressor is essential for maintaining the thermodynamic cycle of refrigeration, ensuring that the system is efficient in removing heat from the designated area.

Understanding this role is key to grasping the overall operation of refrigeration systems, as each component is interconnected, with the compressor acting as the driving force for the entire cycle.
