<P>PROBLEM TO BE SOLVED: To provide a cogeneration system capable of forcibly operating a power generation unit by collecting exhaust heat of a power generation unit regardless of a hot water storage amount in a hot water storage tank. <P>SOLUTION: This cogeneration system comprises the power generation unit 10 receiving fuel supply from the external and generating power, an exhaust heat collection cooling liquid circulation pipe 22 for collecting the exhaust heat generated when the power generation unit generates power by circulating the cooling liquid, and cooling the power generation unit, the hot water storage tank 21, a hot water circulation pipe 23 circulating the hot water in the hot water storage tank, a heat exchanger 24 exchanging heat between the exhaust heat collection cooling liquid circulation pipe and the hot water circulation pipe, and a control device 32 controlling the operation of the power generation unit and the circulation of the exhaust heat collection cooling liquid circulation pipe and the hot water circulation pipe. The exhaust heat collected by the exhaust heat collection cooling liquid circulation pipe can be supplied to a prescribed thermal load terminal 51, and the control device 32 detects that the hot water storage amount of the hot water storage tank is more than a prescribed amount, and forcibly controls the start of the operation to the prescribed thermal load terminal, in the forcible operation of the power generation unit. <P>COPYRIGHT: (C)2007,JPO&INPIT |
