Abstract (en)
An object is to provide a supercritical steam compression heat pump whose heating capacity can be increased by enabling the operation thereof without reducing a high pressure. In a supercritical steam compression heat pump 2 in which CO 2 refrigerant is employed as a working medium and a refrigerant circulation circuit 18 is formed in which a compressor 9, a heat sink 11, an internal heat exchanger 14, depressurizing means 15A and 15B, evaporators 17A and 17B, and a low-pressure gas/liquid separator 26 are connected with pipes in this order, the low-pressure gas/liquid separator 26 is disposed in an intake pipe 18A that connects an outlet side of the internal heat exchanger 14 and the compressor 9.
