What is a Condensing Unit?
Basically, condensing unit is a high side assembly of a whole refrigeration system. These units are temperature-control devices used in refrigerators, heat pumps, air conditioners and chillers. A condensing unit is an assembly of condenser, compressor, electronic controls, mounting plate, motor, pump and coils. It has the function of a heat exchanger to condensate and cool down the incoming refrigerant vapor into liquid and a fan for blowing outside air through the air exchanger section to cool down the refrigerants. In the working process of a condensing unit, condensers apply pressure to gas until it becomes a liquid out as heat. Then it will circulate the cooled liquid through a closed system, where it absorbs heat as it returns to the compressor. All condensers are heat exchangers. A fan inside a condensing unit force air over the metal coils to cool areas, outbound from the condenser, or it is ventilated on the warm side. In air conditioner condensing units, i...
