| Abstract |
The purpose of this study is on the evaluations of the energy saving effects by cogeneration system in the view point of its operating methods and building needs. The followings are the results of this study. ①6??building needs are specified and every each hourly cooling, heating and electricity loads and heat-electricity ratio(HER) also are calculated. In apartment, monthly and hourly HERs are scattered, and in office, monthly HER is converged but hourly is scattered. But in hotel, monthly and hourly HERs are all converged. ②The energy flow diagram is completed. And also energy saving equations are introduced from the diagram. As the result of computational evaluation, ③the most expected energy saving effect is happened at the condition of apartment with fuel-cell type cogeneration operating by heat-loads following method. ④With heat-electricity balance operation, hotel and hospital is expected as highly effect of energy saving. ⑤This study recommends, the most effective operating method for apartment is heat-loads following operating method, for office is electricity-loads following method. And for hotel, it depends on the cogeneration systems. |
