PURPOSE:To furnish a cogeneration system which can supply hot water of a stable temperature at all times and which is small in size and has high performance, by storing hot water by a quantity being necessary at the time when a hot water supply capacity is insufficient and by using it, when a surplus hot water supply capacity exists. CONSTITUTION:The title apparatus has a generator 5 driven by an engine 4, and electric utilities 53. Besides, it comprises an engine cooling water circulation circuit 7, a hot-water heat exchanger 71 provided in this circuit, and a hot-water circulation circuit 1 provided between a hot-water storage tank 21 and the hot-water heat exchanger 71. In the hot-water circulation circuit 1, a mixing valve 3 connected to the hot-water heat exchanger 71 and a mixing valve control device 3A such as a thermostat provided for controlling opening and closure of the mixing valve 3. According to this constitution, hot water in the hot-water storage tank 21 is mixed with low-temperature water of a flowing water circuit 10 by the mixing valve 3 and the hot water of a stable temperature can be supplied at all times. |
