It flows into the inflow chamber 41 of the separator 40. In addition, in the medium temperature bath 8, the dilute absorption liquid is heated by the heat source, and a stirring flow is generated in the dilute absorption liquid by the ultrasonic vibrator 30, thereby promoting heat transfer in the dilute absorption liquid and causing it to boil. . In the example, the heat transfer of the dilute absorption liquid increased by about 10% in terms of thermal efficiency ratio due to ultrasonic radiation. As a result, the dilute absorption liquid in the medium-temperature tank 8 becomes a gas-liquid two-phase flow and reaches the second pumping path 35.
b and flows into the inflow chamber 41 of the separator 40. And the first. The gas-liquid mixture discharged into the inflow chamber 41 from the openings at the upper ends of the second liquid pumping paths 35a and 35b has its refrigerant vapor flowing into the upper vapor chamber 44, and the intermediate concentration absorbing liquid from which the refrigerant vapor has been separated. The liquid accumulates in the absorption liquid chamber 42, resulting in a gas-liquid separation state. Further, the intermediate concentration absorption liquid in the absorption liquid chamber 42 flows into the high temperature heat exchanger 61 through the liquid sending pipe 85, and the refrigerant vapor in the vapor chamber 44 flows into the low temperature generator 51 through the steam pipe 70. . Further, when the intermediate concentration absorption liquid in the absorption liquid chamber 42 increases, the intermediate concentration absorption liquid overflows through the overflow pipe 45, and the liquid level in the absorption liquid chamber 42 is kept substantially constant. Furthermore, conduit 4
In the passage through 7, the cold/hot switching valve 48 is closed during the cooling cycle, and the cold/hot switching valve 48 is opened during the heating cycle, and the intermediate concentration absorbing liquid is introduced into the evaporative absorption pipe 55.
