ABSTRACT:
A refrigeration system which utilizes a portion of the energy of the condensate liquid to elevate the pressure of the gas in the suction line above the evaporator pressure is disclosed. A jet enthalpy compressor is used as a means for elevating the suction line pressure. The refrigeration system contains a reservoir which stores liquid and gas refrigerants. The liquid refrigerant from the reservoir passes to an evaporator wherein it evaporates to a low pressure gas, which is discharged into the suction line. A jet enthalpy compressor is disposed between the reservoir and the suction line. The jet enthalpy compressor contains ejectors, each ejector having a nozzle end placed in the suction line. Gas refrigerant from the reservoir is controllably discharged into the suction line through the nozzle ends of the ejectors to elevate the pressure in the suction line. The gas through the ejectors may be pulsed to further improve the efficiency of the refrigeration system.
