There is an absorption heat pump (for example, Japanese Patent Laid-Open No. 58-69372) that takes out water at a temperature higher than the temperature. This kind of absorption heat pump device is useful as a device for recovering low-value waste heat of low utility value to obtain high-value heat of high utility value, and also of the waste heat after heat recovery by this device.

熱回収率の低下が防止される。In this machine, the load is large and the temperature of the hot water inlet (the temperature of the hot water flowing out of the heat exchange unit (24)) is lower than the temperature of the discharged hot water outlet (the temperature of the discharged hot water flowing out of the heater (20)). In this case, the three-way valve (V) is controlled by the signals of the detectors (S 1 ) and (S 2 ) via the controller (C), and the bypass pipe (33)
The side flow path is cut off, and the hot water flows to the heat recovery device (25). As a result, the heat recovery unit (25) further recovers the heat of the exhaust hot water into the hot water, thereby improving the heat recovery rate of this machine. The hot water heated in the heat recovery device (25) is sent to the absorber (4), further heated, and sent again to the heat exchange unit (24). Conversely, if the load is small and the hot water inlet temperature is higher than the exhaust hot water outlet temperature, the flow path of the hot water to the heat recovery device (25) is cut off and the bypass pipe
The flow path of (33) is opened, and the hot water bypasses the heat recovery device (25) and is sent to the absorber (4). As a result, the heat of the hot water is not taken by the discharged hot water in the heat recovery device (25), and the reduction of the heat recovery rate of the machine is prevented.
