摘要
建筑节能是建筑研究领域一直以来的重要课题,为促进建筑外墙保温节能经济性提升,在夏热冬冷地区,对外墙保温工程的节能效果进行了研究,并对其进行了节能经济性分析.通过建立夏热冬冷地区建筑外墙传热模型、对保温层不同厚度下的能耗结果分析,明确夏热冬冷区外墙保温对建筑节能效果.结合得到的分析结果,计算建筑全生命周期成本、外墙保温结构经济厚度和经济回收期,从数学角度实现对外墙保温节能经济性效果的分析,以期为建筑节能相关研究提供借鉴.
Abstract
Building energy conservation has always been an important topic in the field of building research.In order to promote the economic improvement of building exterior wall insulation energy conservation,the energy-saving effect of exterior wall insulation engineering was studied in hot summer and cold winter areas,and its energy-saving economic analysis was conducted.By establishing a heat transfer model for the exterior walls of buildings in hot summer and cold winter areas,and analyzing the energy consumption results under different thicknesses of insulation layers,the energy-saving effect of exterior wall insulation in hot summer and cold winter areas on buildings is clarified.Based on the analysis results obtained,calculate the full life cycle cost of the building,the economic thickness and economic recovery period of the external wall insulation structure,and mathematically analyze the economic effects of external wall insulation energy conservation,in order to provide reference for research related to building energy conservation.
