Study on the Operating Characteristics with Load Condition in Hybrid Solar Heating System during Spring Season

봄철 태양열 하이브리드 시스템의 부하조건 변화에 따른 운전특성 연구

This study describes experimental study on the performance characteristics with load condition in hybrid solar heating system during spring season. The room temperatures, the hot water conditions and the lower part temperatures of heat storage tank were changed to analyze the system performances. As a results, the hot water was significantly affected by the ambient temperature. The indoor setting temperature affected the solar fraction. When the low part temperature of the storage tank increased, the temperature of the hot water rose and the temperature of the hot water in morning was affected by the ambient temperature.
