ことを特徴とする吸収ヒートポンプ。A high temperature regenerator, a low temperature regenerator, a first condenser,
It consists of a second condenser, a first evaporator, a second evaporator, a first absorber, a second absorber, a high-temperature heat exchanger, and a low-temperature heat exchanger. Flows into the low-temperature regenerator through the low-temperature heat exchanger, flows into the high-temperature regenerator through the high-temperature heat exchanger, and evaporates and separates the refrigerant.The concentrated liquid passes through the high-temperature heat exchanger and enters the second absorber. After flowing into the first absorber through the low-temperature heat exchanger, a part of the refrigerant vapor generated by the high-temperature regenerator is provided to the first absorber through the low-temperature heat exchanger. Along with flowing into the evaporator, the remainder of the generated refrigerant vapor is provided so as to be able to flow into the second evaporator after directly flowing into the second condenser, and the intermediate hot water pipe is provided with sewage treatment water.
River water etc. are provided to be drainable to sewage, rivers, etc. through the first absorber, first condenser, second evaporator, take out chilled water from the chilled water pipe leading inside the first evaporator, and absorb the second water An absorption heat pump, wherein high-temperature water is taken out from a high-temperature water pipe provided in the order of a vessel and a second condenser.
