What is the primary function of a condenser in a refrigeration system?

The primary function of a condenser in a refrigeration system is to cool the refrigerant vapor. In the refrigeration cycle, the compressor compresses the refrigerant, increasing its temperature and pressure. This high-pressure vapor then enters the condenser, where it is exposed to cooler air or water. As the vapor passes through the condenser coils, it releases heat to the surroundings and condenses into a liquid state. This process is crucial as it allows the refrigerant to transition from a gas to a liquid while carrying away the heat absorbed from the cooling space. This cooling effect is vital for the overall efficiency and effectiveness of the refrigeration system, as it prepares the refrigerant to be cycled back into the evaporator, where it can absorb heat again from the space being cooled.
