The component responsible for transferring heat from the refrigerant to the surrounding air is the condenser. In a refrigeration system, the condenser plays a crucial role in the heat exchange process. After the refrigerant has absorbed heat from the inside of the refrigerated area, it is compressed by the compressor and then sent to the condenser.

In the condenser, the refrigerant transitions from a gas to a liquid state as it releases the heat it absorbed. This process occurs as the refrigerant flows through coils or fins where air is blown over them, removing the heat from the refrigerant and transferring it to the surrounding environment. As the refrigerant cools down due to this heat exchange, it condenses, thereby allowing it to continue in the refrigeration cycle.

Understanding the function of the condenser is essential, as it directly influences the efficiency and effectiveness of the refrigeration system. The evaporator, expansion valve, and compressor each have distinct roles in the refrigeration cycle, but it is specifically the condenser that handles the heat transfer to the air.
