合肥地区典型外保温系统保温层最优厚度研究
|
摘要
对合肥地区某建筑进行模拟建筑能耗分析,得到外墙保温层厚度与相对节能量呈对数关系。通过运用生命周期成本法建立合肥地区典型外保温系统的计算模型,得出合肥地区PU泡沫塑料外保温系统、EPS外保温系统和胶粉聚苯颗粒外保温系统的保温层最优厚度。无机保温砂浆外保温系统不适宜本地区。
This paper conclude a logarithmic relation between external wall thermal insulation layer thickness and relative energy saving after using the PKPM to analyze the building energy consumption of a model from a actual building in Hefei It's an important link of building energy conservation to design insulation layer thickness effectively Through the application of life cycle cost analysis method to establish calculated model of typical external insulation system in Hefei area it's concluded that the optimal layer thickness of PU foam external thermal insulation system is no more than 30 mm;the optimal layer thickness of EPS external thermal insulation system is 40 mm,the optimal layer thickness of powder polystyrene particles is about 40-50 mm,inorganic insulation mortar of external thermal insulation system with optimal thermal insulation layer thickness isn't suitable for this area.
