What is the Definition of High Side and Low Side in Air Condition & Refrigeration Systems?
Definition of Low Side in an Air Conditioning System refers to the components on the low-temperature and low-pressure side of the compressor unit. In an air conditioner, the low side includes the suction or intake side of the compressor unit, suction piping connected to the evaporator coil, the evaporator or cooling coil, and the output-end of the metering device or TEV. Definition of High Side in an Air Conditioning System refers to the components on the high-temperature (above ambient air temperature) and high pressure side of the compressor unit. In an air conditioner in cooling mode these include the output or high pressure side of the compressor unit, the high pressure gas refrigerant line connected to the condensing coil, the condensing coil itself, and the inlet side of the metering device located near the evaporator coil. These parts are named and illustrated at AIR CONDITIONING SYSTEMS and at COMPRESSOR PRESSURE READINGS we discuss air conditioner system high side and low side
