摘要
介绍了现行规范中温差修正系数的选取方法,发现规范对温差修正系数的选取存在一些不足。首先通过理论分析找到影响温差修正系数的主要因素,然后采用数值计算的方法对拉萨、西宁、银川和西安4个地区封闭阳台在建筑朝向、窗墙面积比、窗户类型以及冷风渗透不同组合方案下的自然室温进行了动态计算,最后给出了4个地区在不同组合方案下的温差修正系数推荐值。
Presents the selection methods of temperature difference correction factor in current codes, and points out some deficiencies.First,through theoretical analysis,identifies the main factors affecting temperature difference correction factor.And then,calculates the natural indoor temperature of closed balcony in Lhasa,Xining,Yinchuan and Xi＆#39;an under different combinations of building orientation, window to wall ratios,window types and cold air infiltration by using numerical calculation.Finally,gives recommended values for temperature difference correction factor of the four cities.
