Keywords: carbon emission, bio-fuel, trigeneration


A trigeneration system, for the simultaneous production of heating, cooling and electricity, using a heat engine and a vapor compression chiller, running on biofuel, is studied. A system configuration, capable of contemplating the three power demands in a realistic situation, was devised. It consisted of a heat engine driving an electric generator, an electrically driven vapor compression heat pump and a boiler. Part of the heating demand was met by recovering the engine and heat pump condenser waste heats. New criteria, based on energy conservation and carbon emissions principle, were defined to evaluate thermal performance.
