, evaporator 4 in this order, the evaporator 4 pumps up the heat held by waste heat 5 such as hot waste water or waste gas, takes it out from the condenser 2, and supplies it to the load 6.
このヒートポンプ装置では熱源となる廃熱量が不足する
場合にはヒートポンプの能力、成績係数が低下するので
負荷６に熱を安定して供給できない。In this heat pump device, if the amount of waste heat that serves as a heat source is insufficient, the capacity and coefficient of performance of the heat pump will decrease, making it impossible to stably supply heat to the load 6.

的な運転ができないという問題があった。Therefore, as shown in FIG. 3, a cascade type heat pump device has been proposed in which a high temperature heat pump 20 using a high boiling point refrigerant such as R114 is combined with a low temperature heat pump 30 using a low boiling point refrigerant such as R12 or R22. In this cascade type heat pump device, high boiling point refrigerant is circulated in the order of compressor 21, condenser 22, expansion device 23, and evaporator 24, while low boiling point refrigerant is circulated through compressor 31, condenser 32 which also serves as evaporator 24, It is circulated through the expansion device 33 and the evaporator 34 in this order. Then, the heat is pumped up from the air in the single generator 34, and the heat is transferred from the low boiling point refrigerant to the high boiling point refrigerant in the condenser 32, which also serves as the evaporator 24, thereby condensing the low boiling point refrigerant and evaporating the high boiling point refrigerant at the same time. , condenser 22
Heat is extracted from the load 35 and supplied to the load 35. Since this cascade type heat pump device uses air as a heat source, it can be operated stably, but it has a problem that the overall performance coefficient is low and that it cannot be operated economically.
