| 1. | 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。 |
