FROST DAMAGE OF ROOF TILES IN RELATIVELY WARM AREA IN JAPAN-CONDENSATION ON EXTERNAL SURFACE -
(0) Even in relatively warm area in Japan, frost damage of roof tiles occurs. In this study, the influences of several factors on frost damage are considered from a thermal environmental point of view. Condensation on the external surfaces of roof tiles, which is caused by a temperature drop due to nocturnal radiation, is estimated as one of the most important factors to the frost damage. The frequency of condensation was calculated by a numerical analysis. The influence of the parameters, such as the inclination angle and the orientation of the roof, is investigated. It is clarified that a surface condensation on the roof tiles occurs very frequently even in a warm area of Japan, regardless of the orientation of the roof.
