On site analysis of a gas driven microcogenerator incorporating heat pump

This article reports the energetic analysis of a natural gas fuelled micro-cogenerationsystem for applications in residential and small commercial (MCHP) sector combinedwith an electric heat pump (EHP) obtained by experimental tests made in a simulationstation appositely equipped.After reported a brief description of the experimental simulation plant used to valueMCHP/EHP system performances and the components main characteristics, there arefound the advantages of this solution and, finally, is discussed energetic analysis made onthe performances of the system as a whole and on the main components.Particularly there have been simulated two functioning modes in stationaryMCHP/EHP system conditions: the first one is able to simulate a winter functioning withco-production of electric and thermal energy, the second one a summer functioning withco-production of electric, thermal and cooling energy (trigeneration).
