Journal of Japan Society of Energy and Resources, Vol. 36, No. 1 Study on an Introductory Support Tool of Combined Heat and Power Systems for Cold Regions * ** Kiyotaka Takeda Yasuhiro Hamada (2014 8 19 2014 12 22 ) This study aims to verify the effectiveness of optimum utilization of residential combined heat and power (CHP) systems such Gas Engine (GE), Polymer Electrolyte Fuel Cell (PEFC), and Solid Oxide Fuel Cell (SOFC) for energy conservation for cold regions. First, we carried out a questionnaire survey. Second, we predicted electrical demand, domestic hot water demand, and space heating demand from the questionnaire. The results show the margin of error of predicted electrical demand, domestic hot water demand, and space heating demand to the measured values were 14.3%, 21.1%, and 30.6%, respectively. Finally, we developed the simple simulation in order to calculate the energy conservation of CHP systems. The results shows the margin of error of the amount of reduction in primary energy compared with the conventional type (commercial power + non-condensing boiler) of GE, PEFC, and SOFC to values obtained by an optimum simulation using measured demands were 15.8%, 17.6%, and 18.1%, respectively. 25 2 7) GE Web 1)
