Abstract |
Energy saving effect of housing polymer electrolyte fuel cell cogeneration system(PEFC-CGS) which is one of the distributed power source systems was clarified by computer simulation. First, model-base...d simulations were conducted using heating/cooling load data for air-conditioning and hot water supply demand data that are predicted in an experiment house as the inputs of the simulations to study an optimum operation method of PEFC-CGS. As the result, it is clarified that the DSS Electric Power Load Tracking Operation (PEFC-CGS starts when electric power load is needed and stops when not needed, and it runs in the partial output according to electric power load) is the most efficient. Second, in order to confirm energy saving effect of PEFC-CGS in existent detached house, the computer simulations were conducted using demand data measured in two detached houses located in Fukuoka prefecture. As the result, on one house the energy consumption reduction effect by PEFC-CGS was confirmed.show more
