围护结构热工参数与中庭类建筑冷负荷相关性分析

摘要

Taking a large building with atrium in Guangzhou as model,studies the correlation between average envelope window-wall ratio,atrium skylight ratio,average index of thermal inertia,average coefficient of heat transfer and cooling load of building and atrium using orthogonal analysis method.The results show that the average coefficient of heat transfer is moderately correlated to building cooling load,but less correlated to atrium cooling load.Atrium skylight ratio is the main factor which affects the energy consumption of atrium.%以广州某一设有中庭的大型建筑为对象建立模型,采用正交分析方法,研究了建筑外围护结构平均窗墙面积比、中庭屋顶天窗面积比、建筑外围护结构平均热惰性指标、建筑外围护结构平均传热系数与建筑冷负荷、中庭冷负荷的相关性.结果表明,建筑外围护结构平均传热系数与建筑能耗中度相关,与中庭能耗低度相关.影响中庭能耗的主要因素是中庭屋顶天窗面积比.
