基于正交实验法的建筑冷负荷影响因素分析

Analysis on affecting factors of building cooling load by orthogonal experiment method

利用DeST软件对模型建筑的逐时冷负荷进行了模拟,列出了影响冷负荷的7个因素:窗墙比、玻璃类型、墙体传热系数、屋顶传热系数、人员密度、灯光设备负荷、外遮阳,通过正交实验法研究各因素对冷负荷的影响,找到了冷负荷最小时7个因素的最佳搭配,并计算了每个因素对冷负荷影响的显著性水平。

Simulates the cooling load of a model building by the DeST software. Presents seven affecting factors of building cooling load, namely, ratio of window/wall areas, glass characteristics, heat transfer coefficient of wall and roof, occupant density, light and equipment load, shading coefficient. Obtains the optimal combination scheme of the factors under the minimum building cooling load by studying their effects on cooling load using orthogonal experimental method, and calculates the notability of each factor.
