Refrigeration cycle apparatus having refrigerant separating system with pressure swing adsorption

Image Number 3 for United States Patent #4972676.

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.
