摘　　要：将高反射涂层与常用的3种墙体材料组合成15种建筑墙体模型,采用能耗模拟软件DOE 2对该涂层的使用效果进行了分析.结果显示:高反射涂层对夏季非空调建筑的降温效果非常明显,而且热容量越大的建筑,降温效果越明显;在室内温度高于26℃条件下,涂层对通过墙体热流量的降低量非常显著;虽然冬季应用高反射涂层不利于建筑对太阳辐射热量的吸收,但是在计算条件下,这种影响相对较小.The high-reflective coating is used to construct 15 kinds of building wall with 3 other kinds of building materials. An analysis is made of the coating effect with the software DOE-2. Results show that the indoor air temperature decreases dramatically in summer for non-air-conditioned buildings by using the coating;and the larger the building heat capacity is, the lower the temperature is. The coating can reflect the heat effectively while the indoor air temperature is over 26℃. However, the coating＇ s impact on the solar heat absorption is comparatively small.
