西北乡村建筑冬季墙体构造界面结露研究
Interfacial condensation of rural building external walls in Northwest Areas in winter
摘要
Abstract
It is very cold and dry in winter in northwest areas,and the differences of indoor and outdoor thermal and humidity are obvious.Due to the large rural building shape coefficient,the winter condensation of wall exists clearly.Based on survey and testing on indoor thermal condi-tions for the rural buildings in coldest months in winter,taking the rural buildings in Ningxia ar-eas for examples,the paper employs the steady-state heat and moisture transfer stratified analysis method,and analyses the characteristics and influential factors of condensation of wall construc-tion interface.Results show that the model of wall construction affects the condensation of con-struction interface greatly,of which the wall with non-insulation and external insulation energy saving structure is not easy for the condensation to occur,and that the construction interface of wall with internal insulation energy saving structure risks large condensation;accordingly,the thicker the thermal insulation layer is,the more serious the interfacial condensation appears.关键词
