<p><P>PROBLEM TO BE SOLVED: To provide a cogeneration system capable of promoting use by improving heat utilization efficiency. <P>SOLUTION: The cogeneration system is provided with a feeder system 11 generating electric power and heat, a hot water storage tank 21 storing hot water heated by the heat of the feeder system 11, a heating circuit 41 capable of utilizing the heat of the feeder system 11, an operation allowed state determining part 81 determining whether or not operation of the heating circuit 11 is allowed, and a heat supply control part 84 automatically supplying the heat of the feeder system 11 to the heating circuit 41 in response to a stored heat quantity of the hot water storage tank 21 when it is determined that the operation of the heating circuit 11 is allowed by the operation allowed state determining part 81. In the allowed state of the operation of the heating circuit 11, the heat generated by the feeder system 11 is automatically supplied to the heating circuit 41 in response to the stored heat quantity of the hot water storage tank 21, and even if there is no hot water supply demand, the hot water in the hot water storage tank 21 is effectively used in the heating circuit 41 before it gets cold with passage of time or is wastefully cooled. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
