The temperature of the hot water is detected by the liquid temperature sensor 17 in the feedback circuit 6, and the hot water is not sufficiently cooled after being discharged from the engine 1 but is at a predetermined temperature or higher, that is, the minimum temperature required for cooling the engine 1. The controller 15 confirms that the temperature is above. Then, the controller 15 switches the discharge side switching valve 7 to the position “b” to cause the hot water to flow into the radiator 8. Thereby, the hot water is sent to the engine 1 after being cooled in the radiator 8.

Determines that there is air stagnation here, and
The on-off valve 14 is opened for a preset short time to release the staying air to the drain side, and then the on-off valve 14 is closed. Similarly, when the controller 15 confirms that air is accumulated in the radiator 8 according to the detection result of the liquid level sensor 19, the controller 15 outputs a signal to the on-off valve 10 and opens it for a preset short time. Then, the on-off valve 10 is closed after the staying air is released from the drain tank 11.

換率の低下を招来することが回避される。Therefore, even if air bubbles generated in the pipe line are likely to accumulate in the air, i.e., gather at the upper side, if this is detected by the liquid level sensors 18 and 19, the controller 15 determines the on-off valve 10 based on the detection result. , 14 by which the stagnant air does not stay in the pipeline. Thus, it is possible to prevent the air from being mixed into the warm water or the cooling water in the pipeline, causing the pump 2 to run idle or to lower the heat exchange rate.
