碩士 / 國立臺北科技大學 / 建築與都市設計研究所 / 94 / Taiwan is in subtropical area with hot and humid climate. Due to sun irradiation, solar radiation on the roof of buildings is two to three fold more compared to the others planes. The poorly-designed roof causes humidity and heat of internal space. In order to improve the design, this research is conducted using architectural method which the whole system is constructed by steal decks. Basically, this system does not change the appearance of the building. Furthermore, it can be used for heating water meanwhile reduces solar radiation which will lead to lower temperature inside the building.
The methodology is to demonstrate the heat insulation and energy accumulation performance of solar air collector that integrated with double-layer roof of buildings. The U value (the coefficient of heat transmission) of single-layer roof is 1.48 W/㎡．℃, on the other hand, the U value of double-layer roof is 0.81 W/㎡．℃. According to the experiment’s result, it evidences that the proposed device actually benefits from heat insulation, by reducing 45.27％ of the U value. In addition, while the solar radiation accumulated by the collector plane between 8:00 to 16:00 is 4006.86 kcal/m². The amount of energy accumulated by solar air collector is 3337.20 kcal which used to heat the water.
The system performed optimum economically by using renewable and saving energy. It has great potential and can be applied to present housing, new campus, gymnasium, hotel buildings and industry factory buildings, etc.
