高反射率涂层在空调建筑中的应用

Application of Highreflective Coating for Airconditioned Building Wall

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DOE2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.

Abstract:

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 DOE2.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.
