%0 Journal Article %T Strategies Used For Developing Micro-CCHP Structures in Residential and Public Buildings %A Nicolae BADEA %A Nelu CAZACU %A Ion VONCILA %A Ion PARASCHIV %J Annals of Dunarea de Jos %D 2008 %I Universitatea Dunarea de Jos %X The current paper deals with the efficient use of the fossil fuels in the context of DER/DG concept through a unitary approach of the necessary electrical power and thermal energy of an urban residential quarter and proposes the use of micro-CCHP (trigeneration of electrical power, heat and cooling) systems. An analysis of theconsumption structures of electrical power and natural gas is provided for the specific conditions of Romanias¡¯ South-Eastern regions. The paper contains a case study which highlights the imbalance between electrical and thermal consumption throughout a year. It also includes a strategy of designing the micro-CCHP systems according to the ratio between generated electrical power and thermal power (P/Pth) by the system and the same ratio for the consumers previously analyzed. The paper presents a proposed structure of micro-CCHP which has, as basic, thermal engines with fuel cells as well as the overall thermal result of the systems¡¯ forecast for the critical seasons - winter/summer. %K cogeneration %K trigeneration %K fuel cell %K renewable energy %K eficiency %U http://www.ann.ugal.ro/eeai/archives/2008/Lucrare-07-Badea.pdf
