Summary

Fuel cells are energy generating devices that allow an optimal use of natural gas (hydrogen in the long term) for the satisfaction of the thermal and electrical demands of various users; the electrochemical conversion of the fuel is almost without polluting emissions and acoustic impact. On the other hand, ejection heat pumps demand low temperature heat and slight mechanical energy, therefore, it can be convenient their employment in small size and recovery heat fed systems. The paper reports on the performances of an integrated fuel cells-ejection heat pump system, varying the operating conditions (generator, condensation and evaporation temperatures) and the type of refrigerant, with particular regard with low or null ODP fluids. Energetic analysis is carried out on the base of a simulation model of the integrated system, both for a residential and for an hotel load (the latter is particularly adapted because of the contemporary demand of heat and cooling energy for this type of users). First results show the possibility to realize high efficiency systems, with local emissions extremely reduced and acoustic impact nearly absent.
