摘　　要：采用WINDOW7软件研究百叶太阳光反射率和百叶角度对三玻两腔的电动内置百叶中空玻璃和磁控内置百叶中空玻璃太阳得热系数(SHGC)的影响。结果表明,百叶角度越大、百叶太阳光反射率越高,电动内置百叶中空玻璃和磁控内置百叶中空玻璃的太阳得热系数越低,电动内置百叶中空玻璃的太阳得热系数最低为0.108,符合GB/T 51350—2019《近零能耗建筑技术标准》中夏季太阳得热系数≤0.15的要求。电动内置百叶中空玻璃应用在近零能耗建筑时,可选用银色涂料百叶或热反射涂料百叶,并结合采用高遮蔽百叶帘实现其太阳得热系数符合近零能耗建筑应用要求。This study employs WINDOW7 software to investigate the impact of louver solar reflectance and louver angle on the solar heat gain coefficient(SHGC)of electrically controlled built-in louver insulating glass and magnetically controlled built-in louver insulating glass with three panes and two cavities.The results indicate that with increasing louver angle and higher louver solar reflectance,the SHGC of both electrically controlled and magnetically controlled built-in louver insulating glass decreases.The minimum SHGC for electrically controlled built-in louver insulating glass is 0.108,meeting the requirements of the GB/T 51350—2019"Technical Standard for Nearly Zero Energy Buildings",which specifies a summer SHGC≤0.15.When the electric built-in louver insulating glass is used in near-zero energy consumption buildings,silver paint louvers or heat reflective paint louvers can be selected,and the solar heat gain coefficient can meet the application requirements of near-zero energy consumption buildings with high shielding blinds.
