Abstract

The systematic numerical simulation program is developed to calculate the total energy efficiency of housing polymer electrolyte fuel cell co-generation system (PEFC-CGS) which is combined with hot water floor heating (HWFH). This simulation program can also predict actual building physics of heat transfer such as mutual radiant heat among interior surfaces and thermal strage relating with piping pitch of hot water and so on. The indoor temperature can be controlled by PMV (Predicted Mean Vote) to take account of thermal sensing affected radiant heat. As the results, it is clarified that the primary energy consumption is reduced up to 12% in winter because of the utilization of exhaust heat from PEFC-CGS and decreasing of indoor temperature for space heating by floor heating utility.
