COMBINATION OF A VACUUM SOLAR COLLECTOR SYSTEM AND AN INTERNAL-COMBUSTION ENGINE IN A LOCAL HEAT NETWORK

Different measures to reduce the space heating consumption can contrib ute to a more rational use of energy. Such measures are for example th e use of solar collectors and the application of the principle of coge neration by block-type thermal power stations (BTP) with internal comb ustion engines. This contribution presents some part of the results of an investigation in which the dimensioning of an internal combustion engine under the special conditions of the combination with a solar-he ating system was analyzed. Concerning the course of the yearly duratio n curve which is an important criterion in dimensioning a BTP it can b e found out that the shape of the course looks like a step. This is su itable for the block-type thermal power station if the thermal power o f the combustion engine modules is chosen in a way that they fit in th ese steps.
