The thermostatic expansion valve controls the feed of liquid refrigerant to the evaporator circuit of the cascade condenser and by means of an orifice reduces the pressure of the refrigerant to the evaporating or low side pressure The reduction of pressure on the liquid refrigerant causes it to boil or vaporize absorbing heat which provides a cooling effect The refrigerant vapor travels through the suction line to the compressor suction inlet The compressor takes the low pressure vapor and compresses it increasing both the pressure and the temperature The hot high pressure vapor is forced out of the compressor discharge valve and into the condenser As the high pressure vapor passes through the condenser it is cooled by a fan which blows ambient air across the finned condenser surface The vapor condenses into a liquid and the cycle is repeated The Low Stage uses refrigerant R 508B High pressure liquid refrigerant is fed from the condenser circuit of the cascade condenser through the filter drier and liquid line solenoid valve to the thermostatic expansion valve The thermostatic expansion valve feeds the finned evaporator coil which is located in the air plenum where heat is absorbed to provide a cooling effect within the chamber The refrigerant vapor travels through the suction line to the compressor suction inlet The compressor takes the low pressure vapor and compresses it increasing both the pressure and the temperature The hot high p
