Each crankshaft rotation achieves actions: suction, compression, and discharge. Selecting a proper refrigeration compressor or air conditioning compressor requires finding a compressor rated for the desired refrigerant for the application. It circulates with the refrigerant throughout the system. Compressor: The compressor is the pump that enables the flow of the refrigerant. m and V 3/s) respectively, and v is the specific volume (m3 i /kg) of the refrigerant at compressor inlet. These machines have to be started up without any operational issues. Seltec compressors are assembled units which use only a few basic body styles. from the temperature controlled space as the refrigerant absorbs heat when it changes state from a absorbed heat is removed from the refrigeration system in the condenser as the refrigerant changes liquid to a gas in the evaporator. <> Calculate the thermal advantage (Coefficient of Performance) for the heat pump. 4 Pages. They use compression to raise the temperature of a low-pressure gas, and also remove vapor from the evaporator. Compressor model MX21FBa Voltage 220-240V 50Hz ~1 Refrigerant R404A APPLICATION COMPRESSOR MOTOR Application Low Back Pressure Displacement 20,72 cm³ Nominal Power 3/4 hp Refrigerant R404A Diameter 34,93 mm Voltage/Frequency 220-240V 50Hz Evaporating Temp.
