In order to provide a refrigeration cycle of a heat pump type, a refrigeration cycle circuit circulates a mixed refrigerant, including of a high boiling point refrigerant and a low boiling refrigerant and filled with a predetermined concentration ratio, at least through a compressor, a condenser and an evaporator. A refrigerant separation system comprises an adsorbing section for separating one of the high and low boiling point refrigerants from the mixed refrigerant circulating by the refrigeration cycle circuit by using a pressure swing adsorption method, a reservoir section for temporarily reserving the separated refrigerant and a returning section for returning that refrigerant which remains without being separated by the adsorbing section and without being reserved in the reserving section to the refrigeration cycle circuit.

A refrigeration cycle apparatus comprising: refrigeration cycle circuit means for permitting a mixed refrigerant including a high boiling point refrigerant and a low boiling point refrigerant adapted to be filled having a predetermined concentration ratio to circulate at least through a compressor, a condenser and an evaporator to thereby provide a refrigeration cycle of a heat pump type; and refrigerant separating means having adsorbing means for separating one of said high boiling point refrigerant and said low boiling point refrigerant from said mixed refrigerant to be circulated by said refrigeration cycle circuit means by a pressure swing adsorption method, reservoir means for temporarily reserving said refrigerant other than said refrigerant separated by said adsorbing means, and means for returning that remaining refrigerant which is separated by said adsorbing mean and is not reserved by said reservoir means, to said refrigeration cycle circuit means.
