慶應義塾大学湘南藤沢キャンパスにおけるコージェネレーションシステムの省エネルギー性および環境性評価

抄録

The cogeneration system (CGS) was positively introduced in terms of economy during the bubble economy period in Japan. Considering the issues of fossil fuel resource depletion and global warming, the next logical step would be reviewing the introduction of the CGS in terms of energy conservation. To examine the energy conservation effect of the CGS on the actual situation, we researched the operation situation of the gas engine CGS on Keio University Shonan Fujisawa Campus from November 2004 to October 2005. As a result, the energy conservation effect of the CGS does not reach its maximum, due to insufficient use of the exhaust heat in air conditioning systems. To enhance the effectiveness of the CGS, we examined the air conditioning systems, where the exhaust heat can be mutually reutilized among the air conditioning systems, and indicated the possibility of reducing the primary energy consumption and carbon dioxide emission through the use of the CGS.
