摘要
阐述了稍低于室温的空气经靠墙散流器低速进入后 ,下沉于地面及扩散的概念。介绍了贴地冷气流层速度分布的一般特性 ,分析了风口特性对地面气流速度场及工作区空气温度梯度的影响。
Describes the concept of the supplied air with low velocity and slightly colder temperature from a diffuser close to the wall dropping and spreading on the floor. Presents the general feature of the velocity distribution of the airflow layer close to the floor, and analyses the influences of the characteristics of the diffuser on the airflow velocity field and the temperature gradient in the occupied zone.
