Field study on the effect by introducing a regional energy system at Kitakyushu Science and Research Park

摘要

In Kitakyushu Science and Research Park, a new district energy system has been introduced. In this study, we choose this system as a case study and carried an analysis on efficiency of the power generation and heat release utilization of fuel cell and gas engine in summer by using the recorded data. The results can be summarized as follows; 1) Although the power generation efficiencies of the gas engine and fuel cell are a little bit lower than standard designated value, they are almost running stably. 2) The collected heat energy is lower than the designated value. The heat release utilization, which is used for cooling and hot water, is fairly low. Considering the efficient use of energy, it is a key to have a good use of heat release when we introduce a district energy system. 3) The discard heat energy of the system is very big in this investigation in evaluating the whole systems. It is connected in the future of energy conservation to use primary energy efficiently.
