Abstract: A refrigeration cycle combines a concentrated absorbent liquid and a refrigerant in its vapor phase at low pressure in an absorber which provides, as an output, a liquid-rich refrigerant in solution with the absorbent liquid. The pressure of the absorbent/refrigerant solution is increased and the pressurized solution is supplied to a pervaporation membrane separator which provides as one output stream a vapor-rich refrigerant and as another output stream a concentrated liquid absorbent. The liquid-rich refrigerant output stream is condensed and subsequently expanded to a low pressure into an evaporator where it evaporates extracting heat from the spaced to be cooled. The concentrated liquid absorbent output stream from the separator is reduced in pressure and recombined in the absorber with the low pressure refrigerant vapor exiting the evaporator.
