What is the primary purpose of a refrigeration compressor?

The primary purpose of a refrigeration compressor is to compress and circulate refrigerant throughout the refrigeration system. The compressor takes in low-pressure refrigerant gas from the evaporator, where it has absorbed heat from the environment or from the substance being cooled. This gas is then compressed, which raises its pressure and temperature, making it suitable for releasing heat in the condenser.

When the refrigerant is compressed, it transitions from a low-energy state to a high-energy state. This process is crucial because it enables the refrigeration cycle to effectively move heat from one area to another—from the cooled space to the outside environment through the condenser. The compressor ensures a continuous flow of refrigerant, facilitating the ongoing absorption of heat in the evaporator and its subsequent release in the condenser, which is essential for maintaining desired temperatures in refrigeration systems.
