Performance of cogeneration system incorporating gas engine driven heat pump

Abstract

Cogeneration systems have a large potential for energy saving, especially when they simultaneously produce heat, cold and power as useful energy flows. Various cogeneration systems for combined heat, cold and power production are designed mainly incorporating absorption heat pumps. But compression heat pumps always have higher coefficient of performance than that of the absorption heat pumps. Gas engine-driven heat pump is the compression heat pump driven by gas engine. Cogeneration system associated with gas engine-driven heat pump will have higher efficiency. Detail thermodynamic analyses of such cogeneration system are processed. For a specific building, result of the energy consumption shows that the primary energy ratio of such system is 1.49, which is higher than that of the conventional separated production system.
