室内自然通风环境的数值预测与评价

Numerical Prediction and Evaluation of the Natural Ventilation of Indoor Environment

采用Phoenics软件对常州地区一公共建筑室内自然通风环境进行了数值模拟,得到了室内流场、工作面空气龄分布。基于室内流场和空气龄分布对不同方案室内气流组织进行预测和评价。描述了自然通风状态下室内气流组织,预测了室内空气品质,为评价建筑室内自然通风提供了依据。

The natural ventilation of indoor environment for a public building in Changzhou was simulated by the Phoenics software.The distribution of the velocity filed and air age was obtained.Prediction and evaluation of the indoor filed distribution were made based on velocity filed and air age.The indoor air distribution under natural ventilation was deseribed and the indoor air quality was predicted,which provided a basis for the evaluation of natural ventilation in buildings.
