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。
When calculating the economic thickness of the thermal insulation layer of the building envelope structure in the hot summer and cold winter area, it is considered that not only the winter heating but also the summer cooling should be considered, instead of simply adopting the recommended value directly or determining with experience. According to the characteristics of the Nanjing area, a simple calculation formula for the economic thickness of the thermal insulation layer was obtained. Using this method, the thickness of the thermal insulation layer of the external walls and roofs of typical energy-saving residential buildings in Nanjing was calculated and analyzed.
