 通风管(guan)道(dao)主(zhu)要(yao)应用在工(gong)(gong)(gong)业及(ji)(ji)建(jian)筑工(gong)(gong)(gong)程中，应用领域主(zhu)要(yao)涉及(ji)(ji):电(dian)子工(gong)(gong)(gong)业无(wu)尘厂房净化系(xi)统(tong)，医(yi)药食(shi)品无(wu)菌车(che)间净化系(xi)统(tong)，酒(jiu)店(dian)宾馆、******医(yi)院、工(gong)(gong)(gong)厂及(ji)(ji)写(xie)字楼的中央空(kong)调系(xi)统(tong)，工(gong)(gong)(gong)业污染控(kong)制用除尘、排烟、吸油等排风管(guan)、工(gong)(gong)(gong)业环(huan)境或岗位舒适(shi)用送(song)风管(guan)、煤矿抽(chou)放瓦斯(si)用抽(chou)放瓦斯(si)系(xi)统(tong)、煤矿矿井环(huan)境控(kong)制用送(song)回风系(xi)统(tong)。

　　通(tong)风管道一般有(you):净(jing)化系(xi)统送回风管、中(zhong)央空(kong)调通(tong)风管、工(gong)业送排(pai)风通(tong)风管、环保(bao)系(xi)统吸排(pai)风管、矿(kuang)用抽(chou)放瓦斯管、矿(kuang)用涂胶布风筒等(deng)。

　　在通风系(xi)(xi)统中的(de)风管是(shi)相(xiang)互(hu)连接的(de)一(yi)个整体，必然(ran)得遵循各支(zhi)路阻力(li)平衡(heng)规(gui)律，当(dang)风管系(xi)(xi)统的(de)结构形(xing)式、管道尺寸一(yi)经确定(ding)(ding)，在一(yi)定(ding)(ding)的(de)风机作用(yong)下，各段的(de)风量是(shi)按阻力(li)平衡(heng)规(gui)律自动(dong)分配(pei)的(de)。在设(she)(she)计计算时未经阻力(li)平衡(heng)计算，会导致系(xi)(xi)统实际风量分配(pei)与设(she)(she)计不符。
