摘要：自然通风可改善室内空气品质，提高人体热舒适感觉。以徽州传统民居为研究对象，采用多区域气流分析软件CON-TAM 模拟分析民居夏季白天和夜间自然通风网络，探讨不同驱动力下民居换气次数变化规律。结果表明：民居白天与夜间自然通风网络有所不同，白天在室外风下形成了贯穿厅堂的穿堂风，厢房存在单侧通风，夜间厢房和厅堂都形成了热压通风，且风压通风加强了夜间自然通风；白天厢房、厅堂、天井换气次数值依次为9.89，15.25，50.01h -1，夜间厢房、厅堂、天井换气次数分别为1.74，7.58，8.41h -1；各区域换气次数均满足最小新风量通风要求；厢房白天和夜间均只受热压作用，厅堂和天井白天主要受风压作用，夜间主要受热压作用。

(School of Civil Engineering and Architecture,Anhui University of Technology,Ma ’anshan 243032,China)Abstract:Natural ventilation is an effective measure to enhance indoor quality and to improve the comfort of human thermal.Taking Huizhou traditional dwelling as the investigated building,multi-zone flow analysis software CONTAM was employed to simulate the daytime and nighttime natural ventilation network of the traditional dwelling in summer to obtain the rule of air change rate with different driving force.The results show that daytime natural ventilation network is different from that of nighttime in the dwelling;during daytime,cross ventilation throughout the hall is produced,and the bedroom occurs single-side ventilation;at night the bedroom and hall both generate buoyancy-driven natural ventilation,and natural ventilation at night is strengthened for the existence of wind-driven natural ventilation at the same time;during daytime,the air change rate of the bedroom,hall,patio is 9.89,15.25,50.01h -1,while the air change rate of the bedroom,hall,patio is 1.74,7.58,8.41h -1during nighttime,respectively,and the air change rate of each zone satisfies the minimum fresh air ventilation requirement.Moreover,the bedroom is only affected by thermal pressure regardless whether daytime or nighttime,while the hall and the patio is affected primarily by wind pressure during daytime,and is mainly driven by thermal pressure during nighttime.
