摘　　要： 将夜间通风视为阶段性通风,利用自然通风室内温度计算方法,得到求解夜间通风建筑室内温度的求解模型.对两房间进行夜间通风实验,监测室内温度,比较了换气时间及夜间通风换气次数对夜间通风效果的影响.利用夜间通风室内温度计算模型对实验工况进行计算,将实验测试温度与数学分析数据进行了比较,结果显示两者较为吻合,证明该夜间通风室内温度计算模型具有一定的工程适用性. Abstract. A calculation method for night ventilation was presented by considering the air flow rate as piecewise function and utilizing the calculation method of natural ventilation. A night ventilation experi- ment was done to compare the effect of ventilation time and air flow rate, and the temperature of experi- mented rooms was calculated by the model. The results of experimental and mathematical calculations were compared. It has been shown that they are in good agreement, so the calculation method on night ventilation can be used in engineering.
