The purpose of the condenser in a refrigeration cycle is to release heat. In the refrigeration process, the refrigerant absorbs heat from the environment, typically from the area being cooled, while in its gaseous state. This refrigerant then flows to the condenser, where it is compressed and changes from a gas to a liquid. During this phase change, the refrigerant releases the absorbed heat into the surrounding environment, typically through coils that allow air or water to carry away the heat. This heat exchange process is crucial for the cooling cycle, as it allows the refrigerant to return to a low-energy state and continue the cycle.

In contrast, evaporating refrigerant is primarily the function of the evaporator, where it absorbs heat from the surrounding space. Absorbing heat is also a function of the evaporator rather than the condenser. Increasing pressure is a role played by the compressor in the cycle, where it compresses the refrigerant to increase its pressure and temperature, preparing it for the heat-exchange process that occurs in the condenser. Thus, the main role of the condenser is indeed to release heat, making it fundamental to the refrigeration cycle's efficiency and effectiveness.
