<P>PROBLEM TO BE SOLVED: To provide a co-generation apparatus miniaturized by dispensing with a hot water storage tank. <P>SOLUTION: The co-generation apparatus comprises a first passage 52 supplying a heat load 50 with water from a water supply source 46; an exhaust-heat heat exchanger 54 exchanging heat between water flowing through the first passage 52 and cooling water of an engine 22 to raise temperature; a first solenoid valve 56 controlling the flow of water raised in temperature by the exhaust-heat heat exchanger 54; a second passage 60 connected to the first passage 56 and by-passing the exhaust-heat heat exchanger 54 and the solenoid valve 56; a boiler 62 raising the temperature of water flowing through the second passage 60; and a second solenoid valve 64 controlling the flow of water raised in temperature by the boiler 62. The operation of the first and second solenoid valves 56, 64 is controlled based on the temperature T1 of cooling water of the engine 22 and the temperature T2 of water at a junction 52b of the first and second passages 52, 60. <P>COPYRIGHT: (C)2010,JPO&INPIT |
