南京建筑围护结构保温层经济厚度计算研究

Calculation of economical thermal insulation thickness of building envelope in Nanjing

计算夏热冬冷地区建筑围护结构保温层经济厚度时,认为既要考虑冬季供热,也要考虑夏季供冷,而不应简单地直接取用推荐值或凭经验来确定。根据南京地区的特点,得出了一个简单的保温层经济厚度的计算式,并使用该方法对南京地区典型节能住宅建筑外墙和屋面的保温层厚度进行了计算分析。

Considers that the calculation of the economical thickness should take both winter heating and summer cooling in hot summer and cold winter zone into account, and not directly apply a recommended or empirical value. In the light of Nanjing local characteristics, obtains a simple formula for calculating economical thickness, and uses it to calculate and analyse the thermal insulation thickness of exterior walls and roof of typical energy efficient residential building in Nanjing area.
