<P>PROBLEM TO BE SOLVED: To provide a cogeneration system capable of preventing high temperature tapping, and capable of securing safety. <P>SOLUTION: The cogeneration system 100 is connected to a hot water tap 66b being a hot water using portion 66 and a bathtub 66a of a bathroom, and it is equipped with a hot water storage tank 18, a power generating unit 24, and a mixing unit 44. The mixing unit 44 connects a hot water supply path 48 and a water supply path 4, and it is equipped with a mixing path 40 mixing tap water supplied from a water pipe 2 with hot water supplied from the hot water storage tank 18, and a mixer 14 mixing the hot water and the tap water. If stopping of hot water supply is determined by a hot water supply amount sensor 12, a mixing ratio of the mixer 14 is maintained a predetermined time. After passage of the predetermined time, a tank solenoid valve 36 is closed to cut off a tank hot water supply path 34 in an upstream side of a connection part 42 of the hot water supply path 48 and the mixing path 44. <P>COPYRIGHT: (C)2009,JPO&INPIT |
