摘要
对现行暖通规范所给单位门窗缝隙长度冷空气渗透量综合修正系数的理论推导提出了不同看法,认为朝向修正系数修正在风量上较为合理,附加风量是朝向的函数,以此为基础重新推导了综合修正系数,并给出了与原修正系数的比较。
Expresses different opinion on the basis of
derivation of the factor given in the current regulation, based on the points that the orientation
correction made to the air flowrate is more reasonable and that the additional air flowrate is a
function of the orientation, derives a new correction factor and gives its comparison with that by
the current calculation.
