What component converts vapor refrigerant to a high-pressure liquid?

The condenser is the component in a refrigeration system that converts vapor refrigerant into a high-pressure liquid. During the refrigeration cycle, vapor refrigerant from the evaporator enters the condenser. Here, the vapor releases heat to the surrounding air or water, which causes it to cool and condense into a liquid form. This process occurs at high pressure, hence the resultant liquid refrigerant is also at a higher pressure compared to its state before entering the condenser.

This high-pressure liquid refrigerant then continues its journey through the cooling system, typically passing through an expansion valve where it experiences a drop in pressure before entering the evaporator. Understanding the role of the condenser in the refrigeration cycle is crucial for comprehending how a cooling system operates, making it clear why it is identified as the component responsible for this specific conversion in the context of the question.
