摘要
二氧化硅气凝胶具有良好的透光保温性能,二氧化硅气凝胶-石蜡玻璃窗作为高性能建筑玻璃能有效降低建筑能耗。通过设计不同气凝胶厚度和导热系数,研究对气凝胶-石蜡玻璃窗保温隔热性能的影响。结果表明:随着二氧化硅气凝胶填充厚度的增加,玻璃窗内表面温度升高,热流密度降低。气凝胶厚度由10 mm增加到30 mm和50 mm,内表面温度分别增加33.33%和39.67%;热流密度分别降低26.93%和34.53%。当二氧化硅气凝层厚度为30 mm时,随着气凝胶导热系数增加,玻璃窗内表面温度降低,热流密度升高。
The silica aerogel has good properties of light transmission and heat prevention.The silica aerogel-paraffin glass window can effectively reduce building energy consumption as high-performance architectural glass.The effect of aerogel-paraffin glass window insulation performance is studied by designing different aerogel thicknesses and thermal conductivity.The results show that with the increase of silica aerogel filling thickness,the inner surface temperature of the glass window increases and the heat flux density decreases.The aerogel thickness increases from 10 mm to 30 mm and 50 mm,the inner surface temperature increases by 33.33%and 39.67%,respectively;the heat flux density decreases by 26.93%and 34.53%,respectively.When the thickness of the silica aeration layer is 30 mm,following the increases of thermal conductivity of the aerogel,the inner surface temperature of the glazing decreases and the heat flux density increases.
