What is the main function of a condenser coil in a refrigeration system?

The main function of a condenser coil in a refrigeration system is to reject heat from the refrigerant. When refrigerant gas enters the condenser, it is under high pressure and temperature. As the refrigerant flows through the coils of the condenser, it releases heat to the surrounding environment, typically facilitated by airflow or water flow over the coil surface. This heat rejection process causes the refrigerant to cool and condense from a gas into a liquid state, which is essential for the refrigeration cycle to continue effectively.

The condenser's role is crucial in allowing the refrigeration system to maintain its cycle, transitioning the refrigerant to a liquid state so that it can be expanded and evaporated again in the evaporator to absorb heat from the area being refrigerated. This process ultimately helps in maintaining the desired temperature in the conditioned space. Other components or roles in the refrigeration system, such as heat absorption or distribution, do not pertain to the primary function of the condenser coil.
