CRYOGENICS 8/25/04 REFRIGERATION CYCLEThe REFRIGERATION CYCLE shown here is a typical R-22 system. The compressor andthermal expansion valve are the boundaries for the high and low 's important to understand that a refrigerator is a heat engine that operates inreverse. Energy is transferred from a low level to high level, which is contrary tothe spontaneous processes that occur in nature. To accomplish this transfer, anamount of work must be supplied dependent on the temperatures must be added to this workload to compensate for the inefficienciesinherent in heat transfer, inefficiencies that arise from heat exchange equipmentand the irreversible behavior of compression or expansion of the same principles used in this basic system apply to normal cryog
