446 大学の高度熱利用エネルギー供給を目指す熱需要推定方法の検討(省エネルギー(4))

抄録

In order to use thermal energy effectively by applying the Cluster Energy Management System (CEMS) to universities, estimating the energy demand in universities is studied. For combining plural campuses from the CEMS viewpoint, dynamic demands of electricity and thermal energy including heating and cooling are needed. Large capacity cogeneration systems (COS) would be placed at the campus where the largest thermal energy demand is requested. To operate the CGS at nominal condition for appropriate time period, the information on dynamic demand amount of thermal-energy existing in the campus as well as the information on when and what amount electricity to be transferred to other campuses are required. To develop the demand model, the existing capacities of air-conditioning systems and power facilities in campuses and the dynamic change in demand depending on the ambient temperature, time period of use, capacity of the number of students, etc. are needed. For developing the energy demand model in universities, we study on the relation between thermal energy demands, ambient temperatures of five campuses of Keio University.
