摘要: 为研究间隔材料为高透明低密度有机玻璃的中空玻璃是否具有优越的热工性能,制作了几种尺寸不同、间隔材料不同、材料厚度不同的双中空玻璃进行热工性能、光学性能试验研究并对比了相关参数,探究不同检测环境下光热参数结果是否相近. 结果表明:现场环境下测试结果与实验室测试结果基本相符;含有机玻璃中间层的双中空玻璃有较低的紫外线透过率,有机玻璃越厚,传热系数和遮阳系数越低;在基本不增加中空玻璃重量的基础上,含有机玻璃中间层的双中空玻璃可实现低传热系数和高可见光透过率,相较于一般双中空玻璃保温隔热性能更好,更适合用在冬寒夏热地区的阳光房或建筑采光顶中. 研究结果可为该种新型双中空玻璃的广泛运用提供物理性能方面的评价依据.

Abstract:In order to study whether the insulating glass whose spacer material is high transparent and low density acrylic hassuperior thermal performance, several double insulating glass with different sizes, spacer materials and material thicknesswere made for thermal and optical performance test and comparison of related parameters to explore whether the results ofphotothermal parameters under different detection environments are similar. The results show that the test results in the fieldenvironment are basically consistent with those in the laboratory. The double insulating glass with acrylic intermediate layerhas lower ultraviolet transmittance, and the thicker acrylic is, the lower heat transfer coefficient and shading coefficient is.On the basis of basically not increasing the weight of insulating glass, double insulating glass with acrylic intermediate layercan achieve low heat transfer coefficient and high visible light transmittance. Compared with general double insulatingglass, it has better thermal insulation performance and is more suitable for use in sunlight rooms or building daylightingroofs in cold winter and hot summer areas. The research results can provide a basis for the evaluation of the physicalproperties of the new type of double insulating glass.
