摘要
为研究遮阳金属百叶帘的隔热性能,本文通过模拟太阳光源的遮阳系数测试平台,对3mm透明玻璃的得热系数、遮阳金属百叶帘的遮阳系数和不同状态下3mm透明玻璃内外表面温度进行了测试与分析。分析结果表明:遮阳金属百叶帘关闭状态时能阻挡约87%的太阳辐射热量、水平状态时能阻挡约43%的太阳辐射热量,分析结果对遮阳金属百叶帘的实际隔热效果评价具有指导意义。
In order to study thermal insulation performance of the metal venetian blind for shading,the solar heat gain coefficient of 3mm clear glass、the shading coefficient of metal venetian blind for shading and inner-outside surface temperature of the 3mm clear glass under different conditions are tested and analyzed by the shading coefficient test platform that is based on solar-simulated light source.The results show that the metal venetian blind for shading holds about 87% of heat from the solar radiation when the metal venetian blind is closed,and the metal venetian blind for shading holds about 43% of heat from the solar radiation when the metal venetian blind is levelled.The analytical results have guiding-significance for thermal insulation evaluation of the metal venetian blind for shading.
