摘　　要：为研究室外风速随着建筑物高度的变化,对高层建筑外窗传热系数的影响,参考已有文献导出了外窗传热系数随高度变化的计算公式,可用于各种外窗在任意高度下的传热系数计算,对于常用的木窗和钢窗给出300m以下的传热系数和传热系数高度附加率表,可供高层建筑外窗热负荷计算参考。Studies the effect of extraventricular wind speed at different heights on the thermal transfer coefficients for outer windows of high-rise buildings,establishes a formula for a variety of thermal transfer coefficients for outer windows at different heights.Presents a formula applicable in any kind of windows at a random height ,gives the thermal transfer coefficient table and additional percantage table of thermal transfer coefficient.For usual wooden and steel windows below three hundred meters,which can be used for calculating the outer windows heating load of the high-rise buildings and to make up the deficiency of the design manual.
