Analysis by indicators performance of the conceptual structures mCCHP-SE using renewable energy sources

This paper refers to an integrated mCCHP systems dedicated for isolated residents with energetic independence. The only energy sources are wood pellet and solar energy. The proposed trigeneration system is based on Stirling engine, photovoltaic panels, thermal solar collector and boiler. Nowadays the mCHP systems use conventional fuel least partial. In addition these systems do not offer an adequate correlation between power to heat ratio of the consumer demands and this ratio of the mCHP systems. Moreover, in summer period the energetic efficient is quite low. This paper removes the above disadvantages by using only renewable energy sources including for the prime thermal mover. The proposed mCCHP system utilizes the exceeding amount of heat in the summer for producing the necessary cooling. The global models simulation aiming performances assessment of the mCCHP-SE system shows a total energetic efficiency of 86%, an average ratio power to heat of 0,25, and a fuel saving of 31,61% for medium size home. This project is realized by a consortium of Romanian and Norway partners and supported by EEA Grant no. RO-0054/2009.
