【中文摘要】 由于常规算法的局限性,在实际项目中换算外墙平均传热系数与外墙主墙体传热系数需要计算的工作量较大。通过统计大量的实际工程,按照一定的方法进行分类统计和分析,得到外墙热桥部分与主墙体部分所占面积比。通过公式计算将不同基层墙体条件下的外墙平均传热系数转换至外墙主墙体的传热系数。使用者只需通过简单的查表即可完成相应的转换工作,大大简化了原本复杂且耗时的计算工作,提高设计师应用围护结构节能措施的工作效率和质量。
【英文摘要】 Because the limitation of the conventional method,A lot of work were done for the calculation of average overall heat transfer coefficient of building external wall and heat transfer coefficient of building block filling wall needs mass calculation.The area ratio of external wall heat bridge and block filling wall through analyzing a lot of actual projects was obtained.Then average heat transfer coefficient of building external wall and heat transfer coefficient of building block filling wall by calculating were calculated.The corresponding transfer result can be quickly gotten through the simple table.This method simplified the calculation process which is very complex and time consuming,furthermore,this method enhances the designer's working efficiency and the quality of building energy conservation for envelope.
