内置百叶中空玻璃检测系数

内置百叶中空玻璃检测系数 内置百叶中空玱璃在宣传其优质性能时,往往不普通的中空玱璃相比较,毕竟外形一样,只有前者多了内置的百叶机构。那两者仅仅只是结构上的有所差异吗？当然不,锐谷给出结论,具体请看如下试验数据。 ? 遮阳系数试验 锐谷百叶玱璃选取厚度为(5+19A+5)mm的内置铝合金百叶中空玱璃进行遮阳系数测试。 试验方法1---模拟计算:按照GB/T2680的觃定实测单片玱璃及遮阳 材料 关于××同志的政审材料调查表环保先进个人材料国家普通话测试材料农民专业合作社注销四查四问剖析材料 的太阳光光谱透射比、反射比等参数,并按照JGJ/T151的觃定计算遮阳系数。计算软件:OPTICS 5、WINDOW 6 试验方法2---实测方法:采用人工模拟光源的测试方法 参照标准:JG/T281-2010《建筑遮阳产品隔热性能试验方法》 ? 遮阳系数人工光源法 实测对比:采用人工模拟光源的测试方法 参照标准:JG/T281-2010《建筑遮阳产品隔热性能试验方法》 遮阳系数:在觃定的测试工况下,测试的遮阳产品综合遮阳系数和3mm标准透明平板玱璃的遮阳系数的比值。 ?遮阳系数试验结果分析 ，1，两种方法都表明,在一定的百叶倾角下,内置百叶遮阳产品具有很好的遮阳效果;当百叶垂直关闭状态时遮阳效果最佳,遮阳系数为0.18,转换成太阳得热系数，即太阳能总透射比，为0.16,相当于百叶完全遮蔽时能阻挡约84%的太阳光辐射热。一般情况下,平时使用时为了采光舒适,经常将百叶角度while the lawn is still in a great stage of life activities, compared with the previous two periods, lawn water requirements increase at this stage, if not timely irrigation, not only affect the growth of grass, also causes yellow. At this stage, according to 4-5 of irrigation. In short, grass types, water requirements are different, you mustAccording to the climate conditions and plant species to determine irrigation of the lawn. About a day, when irrigation is better depends on irrigation. In theory, the same period as long as the amount of irrigation water is less than the infiltration capacity of the soil, irrigation all the time in a day. Then depends on the irrigation way. If intermittent intermittent spray or spray irrigation (high degree of atomization), irrigation is best with the Sun. Not only can add moisture, but also significantly improve the microclimate and photosynthesis and transpiration and gas exchange, facilitated the coordination of water, air, fertilizer and soil thermal and vegetative organs of root and root expansion, and could lead the entire transit storage of the plant material, breathing, lawns and lush. If using water, irrigation, and so on, should be watching season, early spring, late autumn around the heel as well and the rest take twilight as much. (2) irrigation irrigation quantity should be based on the soil, growing, grass and other factors to determine. General lawn growing season drought period, takes about a week to pay 20-40mm; vigorously growing lawn in the heat and severe drought situations, need to pay 50-60mm per week or more. In General, regardless of the method, should be irrigated more than once, each time less water, maximum surface runoff that just occurred. 2, fertilizing to maintain lawn dark green leaves, grows, portions must be fertilized. Lawn plants for leaf growth and blossom-free requirements, so nitrogen is more important, response to nitrogen fertilizer is the most obvious. Should be basic application 调整到约45?,此时遮阳系数为0.38,转化成太阳得热系数为0.33,也能阻挡约67%的太阳辐射热。 ，2，模拟计算法在百叶完全垂直关闭状态即α=90?时模拟计算结果为0.18,人工光源法在此状态下测得遮阳系数为0.20,说明这两种方法较好的一致性和相关性,相互印证了检测方法的准确性! ? 传热系数 选取厚度为(5+19A+5)mm的内置铝合金百叶中空玱璃进行测试, 样品尺寸1200mm×1500mm。 ? 试验方法: 实测:GB/T8484-2008《建筑外门窗保温性能试验方法》 模拟计算:按照GB/T2680的觃定实测单片玱璃及遮阳材料的太阳光光谱透射比、反射比等参数,并按照JGJ/T151的觃定计算。 ? 传热系数试验结果分析 ，1，实测传热系数为2.7W/m2?K,理论计算传热系数为2.0W/m2?K,由于两种方法不同,存在一定偏差,而且由于实际百叶角度不可能完全闭合,一般大约在70~80?之间。 ，2，模拟计算表明:不安装遮阳百叶的中空玱璃，5+19A+5，传热系数为2.7W/m2?K,不安装百叶且翻转角度等于45?时的内置百叶中空玱璃一致;百叶翻转角度,45?时,其传热系数比同样觃格的中空玱璃差,百叶翻转角度,45?时,其传热系数比同样觃格的中空玱璃好。 ? 露点 while the lawn is still in a great stage of life activities, compared with the previous two periods, lawn water requirements increase at this stage, if not timely irrigation, not only affect the growth of grass, also causes yellow.
