建筑围护结构传热性能修正及应用研究

On Heat Transfer Corrections and Practice for Building Enclosure

非透明建筑围护结构的实际传热性能和理论设计值往往存在差距,其原因一般与材料、构造、安装、使用中的缺陷或外界环境相关。对围护结构传热性能进行全面的修正时,可首先对围护结构进行分类,考虑外在的环境条件和内在的缺陷影响,然后确定分析要素,建立传热性能修正的方法,考虑各种影响条件之间可能存在的交互作用关系。围护结构传热性能的修正结论可作为绝热材料、围护结构系统的参考,修正方法和各种影响因素的控制方法可作为工程节能设计和施工的指引。

There is often a gap between the heat transfer performance requirements and the actual application effect of building enclosure in the practice project. The cause may be a defect of materials,components,installation,use,or external environment causes. A comprehensive idea of heat transfer performance correction of the enclosure is proposed: the issue starting with the typing of enclosure,considering the influence of external environmental conditions and inherent defects,and then determining the method of analyzing the elements to establish heat transfer performance correction. The analysis and conclusion can be used for the key points of the enclosure material,system,engineering energy-saving design and installation.
