<P>PROBLEM TO BE SOLVED: To provide a cogeneration system capable of automatically filling heating water linked with a power generation system and a heating system. <P>SOLUTION: The cogeneration system includes: the power generation system 10; the hot water supply heating system 30; a heating water bypass circuit L3 for bypassing a flow passage of a heating circuit L2 between an outlet of a heating terminal 33 and a heating water pump 32; a heating water bypass pump 42; and a heating heat exchanger 24 for performing heat exchange between the heating water in the heating water bypass circuit L3 and a cooling liquid. A power generation controller 46 of the power generation system 10 determines that the water filling of the heating water bypass circuit L3 is uncompleted at the start of the first operation of the power generation system 10 after the introduction of the system or at the start of the operation of the power generation system 10 when a passage time after the previous stop of the operation of the power generation system 10 is longer than a predetermined time so as to control the operation of the heating water bypass pump 42. <P>COPYRIGHT: (C)2010,JPO&INPIT |
