직달일사를 이용한 잠열축열식 바닥난방 시스템이 냉방부하에 미치는 영향에 대한 검토 = Effects of Phase Change Material Floor Heating Systems using Direct Solar Gain on Cooling Load

다국어 초록 (Multilingual Abstract)

In this research, the effect of a heating system, which is powered by direct solar energy accumulated in phase change material (PCM)as heat storage material installed on the floor surface, on the cooling load was studied. Cooling load of a test building designed for this research was measured with fan coil unit and factors affecting it were also estimated. Experiments were performed with and without PCM installed on the building floor to understand the effect of the PCM on the cooling load. Additionally, to confirm the experiments results, the prediction calculation formula by average outside temperature and integrated solar radiation was composed using multivariate regression model. The results suggested that the heating system with PCM on the floor surface has the potential to shift electric power peak by radiating heat, stored during the daytime in it, at night, not increasing the total cooling load much.
