창문부착형 열차단 필름의 에너지 성능 분석

This examines thermal and energy performance of heat blocking films in summer. Field measurements and numerical computer simulations were performed for three cases which employed two different types of film on windows. Diverse ratios of window to wall on buildings envelope and building orientations were employed as test variables. Analysis results imply that the heat blocking films were effective to cool down indoor air temperature and reduce the amount of heat removal from indoor space by a cooling system in summer. The effects were more remarkable as the ratio of window to wall increased and the film was applied to the south or east side of building.
