What happens to the refrigerant in the condenser?

In the condenser, the refrigerant undergoes a crucial phase change where it releases heat to the surrounding environment. As the refrigerant flows through the condenser coils, it is typically in a gaseous state after absorbing heat in the evaporator. When it enters the condenser, it is subjected to a cooler environment, often aided by the external air or water used for heat exchange.

As the refrigerant releases heat, its temperature decreases, and it transitions from a vapor to a liquid state. This process is vital for the refrigeration cycle, as it ensures that the refrigerant can return to the evaporator in a liquid form, ready to absorb heat again and continue the cycle.

The choices that involve the refrigerant absorbing heat or expanding do not accurately describe the function of the condenser. The correct understanding of this process is fundamental for managing and optimizing refrigeration systems effectively.
