<P>PROBLEM TO BE SOLVED: To provide a cogeneration system capable of enhancing efficiency to use hot water use equipment such as a heater while suppressing heat release from a hot water storage tank. <P>SOLUTION: The cogeneration system includes: cogeneration equipment 11 for generating electric energy and thermal energy along with operation; the hot water storage tank 30 having a hot water storage chamber 31 for storing hot water heated based on heat of the cogeneration equipment 11; a temperature rise element 5 for raising the temperature of hot water stored in the hot water storage chamber 31; the hot water use equipment 32 for using thermal energy of the hot water stored in the hot water storage chamber 31; and a control part 2 for controlling at least the temperature rise element 5. When hot water is used in the hot water use equipment 32, or when use of hot water in the hot water use equipment 32 is predicted, the control part 2 executes temperature rise control for raising the temperature of hot water stored in the hot water storage chamber 31 by the temperature rise element 5 compared to a case where the hot water use equipment 32 is not used. <P>COPYRIGHT: (C)2011,JPO&INPIT |
