At the same time, the second pipe 1c and another set of high-power fans 1d are used to discharge the dirty air in the room to the outside. Disadvantages of traditional fresh air exchange systems: 1) Traditional fresh air exchange systems use volute fans to deliver or absorb air at the front end of the pipe.
