Abstract
The performance characteristics were investigated of three high-efficiency gas-engine generators with capacities of 300 to 400 kW and two groups of the "Genelink", i.e. exhaust heat recovery absorption water chiller-heater, as main components of cogeneration systems, CGS. Next, computer simulations were made on the CGS in order to evaluate monthly and annual primary energy consumptions and CO_2 emissions for such building use as office, shop, hospital and hotel with ordinary electric, cooling, heating and hot water supply loads. Then, the optimum conditions for application of CGS were discussed from energy saving and environmental points of view.
