Description
A Condensing Unit Refrigeration Compressor is a vital component in commercial and industrial
cooling systems, responsible for compressing and circulating refrigerant to remove heat from
a space. It consists of a compressor, condenser coil, fan, and other components housed in a single
unit. The compressor pressurizes the refrigerant, converting it from a low-pressure gas to a high-
pressure, high-temperature gas. The condenser coil and fan then dissipate heat, allowing the
refrigerant to cool and liquefy before circulating back into the system. Available in air-cooled and
water-cooled designs, condensing units ensure efficient cooling in refrigeration, HVAC, and food
storage applications.
