Subcooling

Subcooling is typically achieved by passing the refrigerant through a heat exchanger (condenser) where it is cooled by a fluid such as water or air. As the refrigerant is cooled, its temperature drops below its saturation point, causing some of the refrigerant to condense into a liquid. This liquid refrigerant is then metered into the evaporator coil where it evaporates and absorbs heat, continuing the refrigeration cycle.

Subcooling is important because it helps to ensure that the refrigerant entering the evaporator coil is at the proper temperature and pressure, which ensures that the cooling or heating output is consistent and reliable. It also helps to prevent issues such as low refrigerant levels, poor cooling performance, and increased
