The Ventilation System is based on the use of special equipment to send fresh air to the room on one side of a closed room, and then discharge from the other side to the outside by special equipment, forming a "fresh air flow field" indoors to meet the needs of indoor fresh air ventilation. The implementation plan is to use high wind pressure and large flow fans, relying on mechanical strength to send air from one side to the room, and from the other side to use a specially designed exhaust fan to discharge to the outside, forcing the formation of a fresh air flow field in the system. While supplying air, the air entering the room is filtered, disinfected, sterilized, oxygenated, and preheated (in winter).
