What is the function of a condenser in a refrigeration cycle?

The function of a condenser in a refrigeration cycle is to cool and condense refrigerant vapor. When the refrigerant exits the compressor, it is a high-pressure vapor that needs to lose heat and change its state from gas to liquid. The condenser achieves this by facilitating the transfer of heat from the refrigerant to the surrounding environment, typically through air or water. As the vapor passes through the condenser coils, it releases heat and cools down, eventually condensing into a liquid state. This process is crucial for the refrigeration cycle, as it prepares the refrigerant to be sent back to the expansion valve and evaporator, where it will absorb heat and continue the cooling process within the system.

The other choices do not accurately describe the role of the condenser. Increasing refrigerant pressure is primarily the function of the compressor, while moisture absorption and separation of water from refrigerant are not direct functions of the condenser itself.
