摘　　要：西北地区冬季严寒干燥,室内外热湿环境差异显著,由于乡村建筑体形系数大,冬季墙体结露问题较为突出。结合对乡村建筑冬季最冷月室内热状况的调研与测试,以宁夏地区乡村建筑为例,采用稳态热湿传递分层分析法,解析墙体构造界面的结露特点与影响因素。结果表明:墙体构造方式对构造界面结露情况影响较大,其中无保温和外保温节能构造墙体不易出现结露,而内保温节能构造墙体的构造界面结露风险较大,并且保温层厚度越大,界面结露越严重。It is very cold and dry in winter in northwest areas, and the differences of indoor andoutdoor thermal and humidity are obvious. Due to the large rural building shape coefficient, thewinter condensation of wall exists clearly. Based on survey and testing on indoor thermal conditionsfor the rural buildings in coldest months in winter, taking the rural buildings in Ningxia areasfor examples, the paper employs the steady-state heat and moisture transfer stratified analysismethod, and analyses the characteristics and influential factors of condensation of wall constructioninterface. Results show that the model of wall construction affects the condensation of constructioninterface greatly, of which the wall with non-insulation and external insulation energysaving structure is not easy for the condensation to occur, and that the construction interface ofwall with internal insulation energy saving structure risks large condensation; accordingly, thethicker the thermal insulation layer is, the more serious the interfacial condensation appears.
