The unidirectional flow system is a diversified ventilation system formed by the combination of central mechanical exhaust and natural air intake based on the three principles of mechanical ventilation system. It is composed of fans, air inlets, air outlets, and various pipes and joints. The fan installed in the ceiling is connected to a series of exhaust ports through pipes. The fan starts, and the turbid air in the room is discharged through the fan through the suction port installed in the room. Several effective negative pressure zones are formed indoors, and the indoor air continues It continuously flows to the negative pressure area and is discharged to the outside. The outdoor fresh air is continuously replenished indoors by the air inlet installed above the window frame (between the window frame and the wall), so as to breathe high-quality fresh air. The air supply system of the fresh air system does not require the connection of air supply ducts, and the exhaust ducts are generally installed in aisles, toilets and other places that usually have ceilings, and basically do not take up additional space.
1) You can enjoy the fresh air of nature without opening the window;
2) Avoid "air conditioning disease";
3) Avoid mildew on indoor furniture and clothing;
4) Eliminate long-term slow-release harmful gases after interior decoration, which is beneficial to human health;
5) Recycling indoor temperature and humidity, saving heating costs;
6) Effectively eliminate various bacteria and viruses indoors;
7) Ultra-quiet;
8) Reduce indoor carbon dioxide concentration;
9) Dustproof;
