<P>PROBLEM TO BE SOLVED: To provide a co-generation system of high total efficiency to allow taking out the power sufficiently and capable of obtaining hot water with high efficiency. <P>SOLUTION: The co-generation system constitutes a simple and effective heat circuit including an external combustion engine of Ericsson type etc. in which the working gas of the engine is expanded with heat to generate power, whereafter thermal regenerative heating of the return gas to an expanding machine is made by a thermal regenerator and heater, being supported by a middle/high temperature heat source, and then the hot water to be supplied is heated in accordance with the temperature level under control of a working fluid circuit, while the gas itself cools to attain finally the minimum attainable temperature with an air-cooled cooler etc. <P>COPYRIGHT: (C)2011,JPO&INPIT |
