<p>PROBLEM TO BE SOLVED: To improve energy efficiency of a cogeneration device which outputs electric power and heat by recovering heat generated in a converter for the generated power, and extracting the recovered heat as a part of thermal output. SOLUTION: When a generator 2 is driven by a gas engine 1, heat exchange is carried out between circulation cooling water (c) of the gas engine 1 and hot water (h) returned from a heat consuming device in a first heat exchanger 3, for heating the returned hot water (h). In addition, heat exchange is carried out between exhaust gas (e) of the gas engine 1 and the hot water (h) fed from the first heat exchanger 3 in a second heat exchanger 4, for further heating the hot water (h). In such a case, a power generation conversion part 5 which adjusts power E of the generator 2 in a desirable output form is provided with a third heat exchanger 6 which heats the hot water (h) fed from the second heat exchanger 4 with heat Q3 generated by an inverter, a rectifier, a cyclon converter as constitutional element of the converter 5. The fed hot water (h) can further be heated.</p> |
