摘　　要：选定一个典型的住宅户型,用标准中规定的塑钢窗冷风渗透量的计算方法,计算了几个城市典型户型冷风渗透热负荷占总热负荷的比例,并进行了对比分析。采用示踪气体法对塑钢窗冷风渗透量进行了实验,得出了塑钢窗单位长度渗风量的范围。通过对计算结果和实验结果的比较分析,认为该计算方法符合实际,可供设计参考。Taking a typical residence layout as an example,calculates the ratio of infiltration heat loss to total heat load of typical residence in several cities by the calculation method regulated in the code.Experiments on the air infiltration by tracer gas method and obtains the range of air infiltration rate per unit length of the crack.According to the comparison between calculation and experiment results,considers that the calculation method is practical and can be referred to during project design.

关 键 词：塑钢窗 冷风渗透量 示踪气体法
