REFRIGERATION SYSTEM COMPONENT PARTS

C2 REFRIGERATION SYSTEMCOMPONENT PARTSCOMPRESSORThe compressor is considered the heart of the REFRIGERATION SYSTEM . It is a pump, like the heart in the circulatory SYSTEM of the human body. However, the compressor only pumps vapor. The compressor has cool refrigerant entering the suction valve to fill the cylinders. This cool vapor contains the heatabsorbed in the evaporator where the refrigerant was boiled and absorbed heat. The compressorpumps this heat-laden vapor to the condenser so that it can be rejected from the SYSTEM . The vaporleaving the compressor can be very warm and on a bottled water cooler with a discharge of pressureof 180 psig. The discharge line at the compressor could easily be 200 condenser rejects heat from the REFRIGERATION SYSTEM that the evaporator absorbed and thecompressor pumped. The condenser receives the hot gas after it leaves the compressor through thedischarge line and is forced into the top of the condenser coil by the compressor.

C3 EVAPORATOR COIL The evaporator absorbs heat into the system. When the refrigerant is boiled at a lower temperature than that of the substance to be cooled, it absorbs heat from the substance.
