What is the portion of a refrigeration system where compression and condensation occurs?

The portion of a refrigeration system where compression and condensation occurs is found in the condensing unit. The condensing unit plays a crucial role in the refrigeration cycle. It houses the compressor, which compresses the refrigerant gas, raising its pressure and temperature. Once the refrigerant leaves the compressor, it enters the condenser coil, where it releases heat to the surrounding environment and condenses into a liquid.

This process of condensation is vital because it transforms the refrigerant from a gas back into a liquid after it has absorbed heat from the evaporator unit. The high-pressure liquid refrigerant then moves to the expansion valve before entering the evaporator to absorb heat again, thereby continuing the refrigeration cycle. Understanding the functions of each component helps distinguish the roles they play, solidifying the importance of the condensing unit in achieving effective refrigeration and air conditioning.
