(1)通风系统：送新风和排气，将有害气体排出室外，把室外新鲜空气送至室内。一般而言，通风系统的流量都很大，因此要求使用阻力较小的空气输送管道，以节省造价和运行费用——螺旋风管就最适用。一般情况下使用镀锌铁管，有腐蚀性及特别潮湿的场所使用不锈钢管。

(1) ventilation system: send fresh air and exhaust, remove harmful gas from the outside, and send fresh air outside to the room. Generally speaking, the flow of the ventilation system is very large, so it is necessary to use the air conveying pipe with less resistance to save the cost and run the cost - the spiral wind pipe is most suitable. In general, galvanized iron pipes are used, stainless steel pipes are used in corrosive and especially damp places.
