建筑多孔围护结构的热湿耦合迁移会严重影响建筑室内环境、建筑能耗以及建筑结构,而建筑热桥往往是发生湿迁移和湿积累最严重的部位.与建筑主墙体相比,热桥受多维效应的影响,热湿耦合迁移更加复杂.为探究建筑中不同部位的热湿耦合迁移,从而精准计算建筑热损失,首先分别从一维平壁墙体和多维热桥两个角度阐述了多孔围护结构热湿耦合迁移的研究进展,然后分析了多孔围护结构热湿耦合迁移对建筑的作用.多孔围护结构尤其是其中的热桥等复杂建筑节点处的热湿耦合迁移对建筑室内环境、建筑能耗及建筑结构有着重要影响,热湿耦合迁移模型、热湿耦合迁移实验等相关研究也亟待深入开展.
Research Progress on Coupled Heat and Moisture Transfer of Porous Building Envelope
The coupled heat and moisture transfer(CHMT)of porous building envelope will seriously affect the indoor environment,building energy consumption and building structure,and the building thermal bridge(TB)is often the most serious part of moisture transfer and moisture accumulation.Compared with the main wall of the building,TB is affected by the multi-dimensional effect,and the CHMT becomes more complicated.In or-der to explore the CHMT in different parts of the building,so as to accurately calculate the heat loss of the building,firstly,the research progress of the CHMT of porous envelope structure is expounded from two perspectives of one-dimensional flat wall and multi-dimen-sional TB,and then the effect of the CHMT of the porous envelope structure on the build-ing is analyzed.The CHMT of porous envelope structures,especially at complex building nodes such as TB,has an important impact on the indoor environment,building energy consumption and building structure of buildings.Relevant research such as CHMT models and CHMT experiments also need to be carried out in depth.
