摘　　要：为研究轻质建筑的高反射墙体节能实效,选定重庆某栋二层轻质活动板房进行节能实测,将高反射涂料轻质活动板房房间与普通涂料房间的空调能耗、外墙内外表面温度等进行对比分析。结果表明:高反射涂层对夏季空调活动板房的外墙外表面温度、内表面温度降温效果和节能效果比较明显,降温率分别为7.6%、18.8%,节能率为12.0%;且降温节能效果与室外太阳总辐射强度及空气温度有关。室外太阳总辐射强度越大、空气温度越高,降温节能效果越明显。In order to study the energy-saving effect of highly reflective wall of lightweight building,a two-story lightweight removable house is selected for energy-saving measurement in Chongqing. The room painted with high-reflective coating is compared with the room painted with conventional coating on air conditioning energy consumption and both indoor and outdoor surface temperature of exterior wall. The results indicate the energy-saving and cooling effect that high-reflective coating acts on both outdoor and indoor surface temperature of exterior wall of air-conditioning removable house in summer is obvious. The cooling rates are 7. 6% and 18. 8% respectively,and the energy-saving rate is 12. 0%.What＇s more,the cooling and energy-saving effects are relevant with the outdoor total solar radiation intensity and air temperature. The greater the intensity of outdoor total solar radiation is and the higher the outdoor air temperature is,the more obvious the cooling and energy saving effect is.
