摘要： The structure is arranged in such a manner that nonazeotropic mixed refrigerant is enclosed therein and a fractioning/separating device is disposed in a low pressure circuit in the main circuit of refrigerating cycle so as to conduct separation operation, the fraction/separation can be conducted at a low pressure in a separation mode, the specific volume of refrigerant gas generated in a reservoir due to heat supplied from a heater is enlarged, and the velocity of gas which moves upwards in the fractioning/separating device can be increased, causing a gas-liquid contact to be promoted. As a result, high performance separation can be conducted at reduced quantity of heat, causing the density of high boiling point refrigerant reserved to be significantly raised. Thus, the composition in the main circuit becomes a composition enriched with low boiling point refrigerant exhibiting excellent heating performance so as to satisfactorily cope with an increase in the load.

摘要： Disclosed is a heat pump comprising a main circuit containing a mixture of non-azeotropic refrigerants, the main circuit including a compressor for pressurizing the mixture, a first heat exchanger operating as a heat sink, a second heat exchanger operating as a heat source, and an expansion device connected between the first and second heat exchangers. A portion of the mixture is supplied through a first feed line from a first junction between the expansion valve and the first heat exchanger and vaporized before being fed to a rectifier where it coacts with liquid refrigerant to cause separation of higher pressure refrigerant of the mixture from the lower pressure refrigerant. The separated higher pressure refrigerant is stored in a reservoir in liquid phase and an overflowed portion of the liquid is returned to the rectifier as said coacting liquid. A second feed line couples a second junction between the expansion device and the second heat exchanger to a bottom portion of the rectifier to complete an auxiliary circuit. A bypass line is established from the bottom portion of reservoir to the second junction accordance with input power demand to control the operation of the rectifier.
