Abstract
The Purpose of this work is to investigate a long-term thermal performance of active solar hot water heating system for the dormitory of university. For this, monitering system including temperature sensors, flow-meters was installed in this system. Measurement was continued for 13 months between April 1st 2004 and May 31th 2005.As results, hot water demand, daily and monthly hot water load distribution which are necessary for the solar system design were suggested. Also thermal stratification in solar buffer tank was observed in the point of increasement of system efficiency. The yearly solar fraction and system efficiency of this system are about 29.5% and 44.9% respectively.Keywards : 급탕량(Hot Water Usage), 급탕량 분포(Hot Water Profile), 시스템 효율(System Efficiency), 태양열 급탕시스템(Solar Hot Water Heating System), 태양열 의존율(Solar Fraction)
