Determination of shelter coefficient of planting vertical 垂直面绿化植物叶片遮阳系数的确定
Simplified test method for determining shading coefficient of shading devices 测定遮阳装置遮阳系数的简化试验方法
The base of ehtv calculation is analyzing the dynamic heat transfer to equivalent temperature difference solar factor of windows , for the shading of windows it used external shading multiplier Ehtv简化计算的基础是将这些动态热作用分解为等效温差、标准窗太阳辐射得热等参数,而且系统地提出外遮阳系数,简化了建筑遮阳对外窗太阳辐射得热的计算方法。
Based on developed experimental testing facility , the shading performances of southing horizontal shading devices , vertical shading devices and integrative shading devices of external windows are measured , the performance parameters including indoor temperature , air - conditioned cooling load and shading coefficient as so on . and the shading coefficient of experimental test results and calculation results based on design standard for building energy efficiency are compared , and the windows5 . 2 simulation results are compared also . the measured results are consistent with the calculation results of horizontal shading devices and vertical shading devices 本文利用研制的建筑遮阳性能检测装置,对南向水平遮阳板、垂直遮阳板和综合遮阳板外窗的遮阳性能(包括室内温度、空调耗冷量和遮阳系数等)进行了实验测试,并对遮阳系数的实验测试结果与节能设计标准的计算值以及windows5 . 2软件的模拟结果进行了比较分析,测试结果表明水平遮阳板和垂直遮阳板外窗的遮阳系数与计算结果比较一致,相对误差分别为2 . 5 %和4 % ,而综合遮阳板外窗的遮阳系数与计算结果的差值比较大,相对误差达到10 %以上。
Building external shading calculation method is put forward based energy consumption simulation results in the standards of hot summer and warm winter zone ( jgj75 - 2003 ) and design standard for energy efficiency of public buildings ( gb 50189 - 2005 ) , but it aims at simple fixed external shading and misfits complicated shading devices , so the validity and rationality of regulation don ’ t gain validation 尽管《夏热冬暖地区居住建筑节能设计标准》 ( jgj75 - 2003 )和《公共建筑节能设计标准》 ( gb50189 - 2005 )提出了建筑外遮阳系数的计算方法,但只是根据建筑能耗模拟软件的模拟结果得出的,且只能针对简单的固定外遮阳,不适合复杂的建筑遮阳形式,因此规定的有效性和合理性并没有得到验证。
