ABSTRACT:
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.
