摘　　要：本文以南京某住宅建筑为研究对象,进行卧室内睡眠和静坐条件下CO_2浓度与新风量关系实际测试。分析了稀释通风下新风量和人员状态对夜晚卧室CO_2浓度的影响。结果显示,稀释通风下,成年人睡眠时最小新风量应不低于20 m^3/(h·p),即换气次数应达到1.1次/h。静坐时,其最小新风量还应在此基础上增加20%。This paper takes a residential building in Nanjing as a research object,conducting field measurements of indoor CO2 concentration and fresh air volume in the bedroom during night,analyzing the influence of fresh air volume and person status on indoor CO2 concentration under the dilute ventilation in bedroom.The results show that the minimum fresh air volume should not be less than 20 m^3/（h·p） for adults and the ventilation should reach 1.1 h-1 when people are sleeping.In addition,the minimum fresh air volume has an increase of 20% on the basis of 20 m^3/（h·p） when people are sitting still.

关 键 词：被动式住宅建筑 室内CO2浓度 人员状态 最小新风量
