What state is the refrigerant in when it enters the condenser of a vapor-cycle cooling system?

In a vapor-cycle cooling system, the refrigerant enters the condenser as a high-pressure vapor. This stage is crucial for the refrigeration cycle, as it signifies that the refrigerant has absorbed heat from the environment within the cabin, raising its temperature and pressure.

As the refrigerant circulates through the evaporator, it evaporates and collects heat from the cabin air, resulting in a low-pressure, low-temperature vapor. Upon exiting the evaporator, this vapor is then directed to the compressor, where its pressure and temperature are significantly increased. After being compressed, the refrigerant turns into a high-pressure vapor due to the added energy and pressure.

This high-pressure vapor is then routed to the condenser, where it releases the absorbed heat to the outside environment. The condenser's role is to cool the high-pressure vapor down, allowing it to transition into a liquid state as it loses heat. Therefore, the refrigerant's condition as a high-pressure vapor upon entering the condenser is a critical aspect of the overall vapor-cycle process, enabling the subsequent phase of heat exchange.
