えられる。Conventional technology A hot water supply system using an engine-driven heat pump sends hot water in a hot water storage tank to an engine cooling water heat exchanger to recover engine cooling water heat, and then passes through an exhaust gas heat exchanger to recover exhaust heat. A device that returns hot water to a hot water storage tank and uses this hot water to supply hot water is conceivable.
しかしこの構造であると、ヒートポンプを冷房
を主に使つている負荷条件である場合に、ヒート
ポンプの凝縮熱をクーリングタワーなどで大気に
放出せねばならずエネルギ有効利用の点から好ま
しくない。 However, with this structure, when the load condition is such that the heat pump is mainly used for cooling, the condensed heat of the heat pump must be released to the atmosphere by a cooling tower or the like, which is not preferable from the point of view of effective energy use.
そこで、ヒートポンプの温水管路と前記温水管

題を有する。Problems that the invention aims to solve However, in this case, heat cannot be transferred unless the condensing temperature is raised to raise the temperature of the cooling water in the condenser above the hot water temperature, so the difference between high and low pressures on the heat pump side becomes large and the pressure of the compressor increases. There is a problem in that the driving horsepower must be increased, which reduces the efficiency of the heat pump.

せることがない。 When the hot water tap 16 is opened to supply hot water, the liquid level in the hot water tank 8 drops, the float 15 lowers, and the second valve 14 opens, allowing city water to flow from the tap 13 into the first pipe 1.
0, so it directly flows into the hot water heat exchanger 18. (At this time, the first valve 9 is closed.) On the other hand, the temperature of the cooling water outlet of the condenser 3, that is, the temperature of the water flowing through the hot water pipe 17, is higher than the temperature of the city water (the outlet temperature is about 45 degrees Celsius). , the temperature of city water is about 15
℃), when the city water flows through the hot water heat exchanger 18, the condensation heat is recovered and the temperature is raised, so the hot water temperature can be increased, and there is no need to increase the capacity of the heat pump compressor, so the efficiency of the heat pump is reduced. I have nothing to do.

くなつて凝縮熱を給湯に利用できない。 On the other hand, if city water is directly supplied into the hot water storage tank 8, the temperature of the water mixed with the high temperature water heated by the engine exhaust and flowing into the hot water heat exchanger 18 is about 55°C, which is about 55°C. The temperature of the flowing water becomes higher (approximately 45℃), and the heat of condensation cannot be used to heat hot water.
そして、利用するにはヒートポンプの能力を高
