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

The function of the compressor in a refrigeration system is to pressurize the refrigerant and circulate it through the system. This process is crucial for the refrigeration cycle, as the compressor takes low-pressure refrigerant vapor from the evaporator and compresses it into a high-pressure vapor. By increasing the pressure, the compressor raises the refrigerant’s temperature, enabling it to release heat once it reaches the condenser.

In summary, the compressor's role as a pressurizer is fundamental to moving the refrigerant through the coils and facilitating the heat exchange process that ultimately provides cooling. Without the compressor, the refrigeration cycle would not function, as there would be no means to circulate the refrigerant and maintain the necessary pressure differentials across the system components.
