实际气候条件下气凝胶玻璃光热特性实验研究
Experimental Study on Optical and Thermal Characteristics of Aerogel Glazing System under Real Climate Condition
摘要
Abstract
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 is 37% less than that through the hollow glass.关键词
