方位・角度別のブラック・ホワイトパネル温度の測定 : 屋外での熱劣化環境の定量化(その3)

抄録

Lifetime of building materials are different by the exposured conditions. Author observed various panel temperature for three years at outdoor exposure site in Tsukuba, Ibaraki Pref. Japan to investigate the deterioration environments. The specifications and exposure conditions of panels were : orientation : south, east, north and west, angle : 0° (horizontal), 30°and 90° (vertical), color : black, dark gray, gray, light gray, white, clear and metalic luster, backside : insulated or not insulated. The thermal deterioration rate and diurnal temperature range related to the movements of sealed joints were quantified and the effects of these various factors were discussed. Besides the analysis of deterioration environments, an estimation method of the horizontal black-panel temperature based on meteorological data and another simple system to predict of the panel temperature from the black-panel temperature were proposed.
