传统建筑室内湿负荷的计算大多不考虑围护结构内表面的散湿量,而围护结构内表面的散湿量尤其是新建节能建筑对室内湿负荷的影响是很大的.以哈尔滨地区为例,分析了严寒地区典型新建建筑不同设置的多层围护结构在最初四年内热质耦合传递对模拟房间湿负荷的影响,并与文献[5]的模拟结果进行对比.分析结果表明:新建建筑围护结构内表面粘贴墙纸或降低围护结构主体砌块的初始含湿量能够降低模拟房间冬季湿负荷;而保温层内侧隔汽层以及围护结构外表面釉面砖的使用都会增加新建建筑的模拟房间冬季湿负荷,但若延后釉面砖的粘贴时间会有所好转.

The conventional calculation of building indoor moisture load always omits the effect of interior moisture release of envelope. However, its effect, especilly that of new-completed energy-saving building, is very important. Took the new-built building in Harbin as an example, analyzed the effect of heat and mass coupled transfer envelope on modeled room moisture load in extremely cold areas. The heating load modeled results of multilayer envelopes with different setting were contrasted with that of literature [5] in the first four-years. The result showed that, for a new-built building, plastering wallpaper on interior of envelope or reducing initial moisture content of concrete is useful for reducing modeled room moisture load in winter; where as the using of vapor retarder on interior of insulation layer or glazed tile on exterior of envelope would increase the moisture load, which would be reduced if defer the time for plastering glazed tile.
