Abstract (en)
[origin: WO9857108A1] A refrigeration cycle utilizing a multi-component refrigerant wherein the compression of low pressure refrigerant vapour is effected in at least two stages of compression (42, 44) with cooling (48, 58), partial condensation and separation (52, 62) from the uncondensed vapour of the condensate formed after each of at least two of the said stages thereby providing two or more condensate streams (64, 70) of different compositions and at different pressures and wherein at least two of said condensate streams are expanded and injected into the returning low pressure refrigerant (40) at different temperatures of said low pressure refrigerant (40).
