摘　　要：为探索建筑参数和居住者行为模式对武汉市梅雨季节农村住宅建筑围护结露的影响,基于试验验证,考虑窗墙比、外墙反射率、窗户开启模式和外墙保温层等因素,采用建筑热环境设计模拟工具包(designer's simulation toolkit,DeST)模拟了武汉市农村住宅室内热湿环境,采用结露率分析了梅雨季节建筑围护结露的情况。研究结果表明:武汉市农村住宅不宜盲目追求自然采光,窗墙比宜取为0.6。当气温急剧升高时保持窗户关闭可以有效缓解结露问题。从防止结露角度考虑,武汉农村住宅不宜增设外墙保温层。In order to explore the influence of building parameters and occupants'behavior patterns on building envelope condensation in Wuhan rural residences during plum rain season,based on experimental verification,considering the factors,such as window-wall ratio,external wall reflectivity,window opening mode and external wall insulation layer,the designer's simulation toolkit(DeST)was adopted to simulate the indoor thermal and humid environment of rural residences in Wuhan.The building envelope condensation in rural residences was analyzed during plum rain season by using condensation rate.The research results show that rural residences in Wuhan should not blindly pursue natural lighting,and the window-wall ratio should be 0.6.Keeping window closed when temperature rises sharply can effectively alleviate the condensation problem.From the view of anti-condensation,it is not suitable to add external wall insulation layer in rural residences in Wuhan.
