The upper supply and bottom exhaust air distribution is formed in painting polluting area with local plenum chamber and slot outlets.
利用局部静压箱和条缝型百叶排风口在污染控制区形成上送风下排风的气流组织形式。
By numerical simulation, the optimal value of the plenum chamber height, the ejector slot height and the wall porosity have been found.
计算结果表明，不同的驻室高度和引射缝高度对实验段马赫数分布有很大影响；
These parameters were the size of the drying chamber, the volume of the air plenum and the air pressure for selecting fans, and the energy consumption.
这些基本参数包括烘干段的长宽尺寸，热风机的风量、风压、烘干谷物所需提供的热量及冷风机的风量和风压。
