摘　　要：在实际气候条件下搭建气凝胶玻璃-中空玻璃对比实验平台,对比测试两者在相同气候条件下辐射、照度、温度等参数,分析气凝胶玻璃在实际气候条件下的采光效果和节能潜力.辐射分析表明,太阳辐射透过气凝胶玻璃进入室内后几乎全为散射辐射,且相比中空玻璃全天减少约45%的太阳辐射得热.照度分析表明,天气越晴朗,气凝胶玻璃的采光效果越好.温度分析表明,相比于中空玻璃,由于气凝胶对太阳辐射的吸收作用,气凝胶玻璃系统各层壁面温度较高,且室外太阳辐射越强,各层壁面温度越高.能耗分析表明,夏季晴天透过气凝胶玻璃的总得热量比中空玻璃减少37%.A comparative experimental platform for aerogel and hollow glass under real climate condition was set up,and by comparing the parameters such as radiation,illuminance and temperature under the same climate conditions,the daylighting effect and energy saving potential of aerogel glass under the actual climatic conditions are analyzed.Radiation analysis shows that the solar radiation becomes almost scattered after entering the room through aerogel glass,and the total solar radiation is reduced by about 45% when compared with the hollow glass.Illumination analysis shows that the weather is clearer,the better the lighting effect of the aerogel glass is.The temperature analysis shows that,compared with the hollow glass,the surface temperature of all layers in aerogel glass is higher because of the absorption of aerogel to radiation,and the greater the outdoor solar radiation,the higher the temperature is.Energy consumption analysis shows that total heat gain through the aerogel glass is37%less than that through the hollow glass.
