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

The purpose of a condenser in a refrigeration system is to reject heat absorbed by the refrigerant. After the refrigerant has absorbed heat from the refrigerated space and changed from a low-pressure gas to a high-pressure gas in the evaporator, it carries this heat to the condenser. In the condenser, this high-pressure gas releases the heat to the surrounding environment, allowing the refrigerant to condense back into a liquid state.

This heat rejection is essential for the continuous cycle of refrigeration, as it ensures that the refrigerant can again become a low-pressure gas and absorb more heat in the evaporator, thereby maintaining the cooling process. The efficiency of heat rejection is critical for the overall performance of the refrigeration system. Without effective heat rejection in the condenser, the system would not be able to cycle properly, leading to insufficient cooling.
