가정용 고분자 전해질 연료전지 열병합 발전시스템의 급탕 적용을 위한 온수 저장조의 최적 설계에 관한 실험적 연구

There are many attempts to use a fuel cell system as a residential power generation system. The purpose of this study is to investigate the optimal design of a water tank for a hot water system when the fuel cell co-generation system is combined with a domestic hot water supply system. The demands of hot water supply per month per home are investigated in Busan for a year. It showed somewhat large differences between the actual demand and the designed demand of hot water, but the actual capacity of hourly averaged hot water demands is analyzed as 60 l/h in this study based on the actual demand. The experiments are performed in the various inlet and outlet locations of nozzles, and the hot water consumption rates. The experimental results are showed that the optimal capacity of the water tank is 200 f when the thermal efficiency, the storing capacity of hot water and the space for installation are considered.
