<P>PROBLEM TO BE SOLVED: To provide a cogeneration system that stabilizes a temperature in a heat-consumption-side circuit and adjusts a consumption-side temperature close to a target purpose temperature. <P>SOLUTION: The cogeneration system includes a heat source unit 101 and a hot water storage unit 102. The heat source unit 101 is provided with an exhaust-heat-side circulation circuit 107. A temperature sensor 108 for a cooling liquid is provided to monitor the temperature of the cooling liquid to be introduced to a gas engine 105. The hot water storage unit 102 includes a storage tank 120, a circulation pump 121, and an exhaust heat-consumption heat exchanger 112. A bypass flow channel 125 is formed to bypass the storage tank 120. A mixing valve 126 is disposed in the upstream side of the circulation pump 121. The opening of the mixing valve 126 is controlled so that the temperature detected by the temperature sensor 108 for the cooling liquid coincides with the predetermined target temperature of the cooling liquid. When the temperature detected by a temperature sensor 113 for heating water is out of a hot water storage target temperature, the target temperature of the cooling liquid is corrected. <P>COPYRIGHT: (C)2013,JPO&INPIT |
