What does the compressor do in a refrigeration system?

The compressor plays a critical role in a refrigeration system by moving refrigerant from the low-pressure side (the evaporator) to the high-pressure side (the condenser). This process involves compression, which increases the pressure and temperature of the refrigerant gas. By doing so, the compressor enables the refrigerant to absorb heat from the environment in the evaporator and release that heat in the condenser, maintaining the necessary temperature differential that is essential for the refrigeration cycle.

Additionally, the compressor helps to control temperatures within the system by regulating the suction pressure. This regulation ensures that the evaporator operates efficiently, allowing it to absorb the maximum amount of heat from the space being cooled. Thus, through its function of transferring refrigerant and managing pressure, the compressor is vital for the effective operation of the refrigeration system.
