となるものである。 In the heat pump device according to the present invention, the non-azeotropic mixed refrigerant compressed by the compressor 1 circulates as shown by the arrow in the figure, and since the non-azeotropic mixed refrigerant is used, the first condenser 2 and the evaporator 6 are condensed. and in the evaporation process,
Non-isothermal properties can be obtained, and by designing the temperature change of the heated fluid in the first condenser 2 to be as close as possible to the temperature change on the refrigerant side, irreversible loss can be reduced and high efficiency can be achieved. can. Furthermore, although the gas phase and liquid phase separated by the gas-liquid separator 3 have the same pressure and the same temperature, the gas phase component is a non-azeotropic mixed refrigerant containing more low-boiling point refrigerant, and the second
During the condensation process in the condenser 4, the temperature further decreases. Therefore, condensation occurs at a temperature lower than that of the condensation process of the first condenser 2, and since it is arranged so as to be able to exchange heat with the air heat source evaporator 6, the temperature is the minimum necessary to prevent the evaporator 6 from freezing. By maintaining this, it is possible to efficiently prevent freezing.
