What form does the refrigerant take as it leaves the condenser of a vapor-cycle cooling system?

As the refrigerant exits the condenser in a vapor-cycle cooling system, it is in the form of a high-pressure liquid.

During the condensation process, the refrigerant, which has absorbed heat from the cabin atmosphere, passes through the condenser where it releases that heat to the outside environment. This process occurs under high pressure. The refrigerant, originally in vapor form, loses energy and transitions to a liquid state as it cools down within the condenser coils. Since the condensation process takes place at high pressure, the resulting refrigerant is characterized as a high-pressure liquid when it exits the condenser, ready to move to the expansion valve or metering device that controls its flow into the evaporator.

Understanding this sequence is crucial as it highlights how the refrigerant cycles through different phases, which is fundamental to the operation of vapor-cycle cooling systems in maintaining an optimal cabin atmosphere.
