摘　　要：排风柜性能受到很多因素影响。本文采用实验方法分析了排风柜拉门高度500mm和拉门全开,不同面风速时,柜内障碍物对排风柜性能的影响。实验结果表明:排风柜面风速分布均匀性与面风速大小和柜内障碍物阻挡率呈线性函数关系;面风速越小,障碍物阻挡率越大,排风柜性能和面风速分布均匀性更差。The performance of fume hood is related to many factors.Experimental method is used to research on the performance of obstacle located inside fume hood when the height of sash is at 500mm and maximum opening under different face velocity.The results show that the performance of fume hood is linearly related to face velocity and the area ratio of open of fume hood blocked by obstacles;the uniformity of face velocity of fume hood becomes worsen when face velocity is lower and the area ratio of open of fume hood blocked by obstacles is greater.
