摘　　要：根据表面隔热机理,通过对普通外墙的理论计算分析,设计了新型的相变墙体。相变材料应用于外墙体外表面,夏季能有效的改善建筑物的外表面热环境,降低传入室内的热量,缓解室内空调冷负荷。同时,提出隔热相变材料的相变温度、掺量在不同气候环境下的选择方法。In this paper, an innovative pcm-wall of which phase change material （pcm） is used as the outmost layer has been designed, through theoretical calculation analysis of common exterior wall based on mechanism of exterior heat insulation. The exterior thermal environment of building with this pcm-wall can be improved effectively in summer, and the quantity of heat transfer through the wall to indoor and the cooling load of indoor air conditioning will be declined. The phase change temperature and proportion of PCM in different climate is put forward.
