摘　　要：针对中庭玻璃屋面内遮阳对室内环境以及能耗的影响,在有无内遮阳工况下分别进行了自然采光照度测试、中庭玻璃屋面内表面温度测试、室内温度测试以及中央空调冷量监测。结果表明,在遮阳工况下,区域1的照度全天有3.5h满足采光标准,超过了300 lux,区域3在17∶00前均满足标准;遮阳卷帘内表面温度降低了0.6~7.7℃,钢结构表面温度降低了4.3~12.5℃;区域2温度在同一时刻最高降低了5.9℃,区域1温度在2种工况下基本维持在27℃左右,同时有遮阳时的空调能耗比未设置内遮阳时下降了6.67%,说明内遮阳可以改善室内热环境,并对降低室内空调冷负荷具有一定的作用。To study the impact of internal shading on indoor environment and energy consumption,the author carried out a series of tests among buildings with and without sunshade respectively, includingnatural light illumination test, surface temperature test of atrium glass curtain wall, indoor temperature testand the central air conditioning cooling capacity monitoring. The result shows that when the sunshade isopen, 3.5 hours of illumination is at area 1 throughout the day, more than 300 lux, meeting the standard,while the illumination at area 3 before 17 oclock can meet the standard; the sunshade surface temperaturedecreases by 0.6？7.7℃, the steel surface temperature decreases by 4.3-12.5℃; compared with the roofwithout shading, the temperature at area 2 with sunshade can drop as much as 5.9 °Cat the same period,however, whether in sunshade or not, the temperature at area 3 fluctuates around 27 ℃, while the air conditioningenergy consumption in sunshade saves 6.67% compared with that roof without sunshade. All ofthese indicate that the sunshade can improve the indoor thermal environment and reduce the indoor airconditioning cold load.
