摘　　要：长江流域住宅夏季空调围护结构负荷受其自身几何和热工参数的影响,但是各参数的影响程度还不明确。本文主要考虑围护结构传热系数、窗墙比和遮阳系数等参数,利用正交试验的原理计算分析夏季空调设计工况下南侧围护结构负荷构成,以确定主要影响参数。对于南侧外围护结构,单位面积负荷与各参数均成正线性相关,其中窗墙比的影响最大。当窗墙比较大时,遮阳系数和外窗传热系数的影响较大,反之外墙传热系数影响较大。利用单位面积负荷及外墙负荷比与参数之间的关系式可以分析确定该地区围护结构节能的潜力,并为确定有效的围护结构节能措施提供依据。The aestival air conditioning load of the residential building envelops is affected by their own geometric and thermal parameters in the Yangtze Valley;however their influence factors are still unclear.This Paper mainly considers the parameters such as heat transfer coefficients of building envelops,area ratio of window to wall and shading coefficient.In virtue of the principle of orthogonal test,it calculates and analyzes the aestival air conditioning load of the southern building envelops in the design situation,so as to determine the main influence parameters.For the southern aspect,the unit area load linearly increases with all the parameters.Among them,the area ratio of window to wall is the most important one,when it is greater,shading coefficient and heat transfer coefficient of the window have more dramatic effect,otherwise heat transfer coefficient of the wall do.By dint of the correlations of the wall-envelop load ratio and unit area load with the parameters,the energy saving potentials can be determined and effective suggestions are provided for the energy saving measures for the building envelops in this area.
