PURPOSE:To improve cooling capacity and heating capacity of a heat pump type refrigerating cycle using non-azeotropic mixture refrigerant. CONSTITUTION:An outdoor heat exchanger 5 of a heat pump type refrigerating cycle using non-azeotropic mixture refrigerant is vertically divided into a plurality of circuits 5a, 5b, 5c. The refrigerant is introduced to an upper part of the uppermost circuit 5a at the time of cooling, divided into a plurality, partly introduced to the upper circuit 5a as it is, fed at the other to an upper heat exchanging tube 5d to be precooled, introduced to at least one or more lower circuits 5b, 5c, fed down in the circuits and then combined. An indoor heat exchanger 3 is so formed that the refrigerant flows in parallel with an air flow A at the time of cooling and flows in a counterflow to the air flow at the time of heating. |
