Working principle
The fresh air system is based on sending fresh air indoors with special equipment on one side of a closed room, and then discharging it outdoors with special equipment on the other side, which will form a "fresh air flow field" indoors, thus meeting the needs of fresh air ventilation indoors.
the implementation scheme is: adopting high wind pressure and large flow fan, relying on mechanical strength to blow air from one side to the room, and the other side using specially designed exhaust fan to discharge it to the outside, so as to force the formation of fresh air flow field in the system. At the same time of air supply, the air entering the room is filtered, disinfected, sterilized, oxygenated and preheated (in winter).
classification:
fresh air system is an independent air handling system consisting of air supply system and air exhaust system, which can be divided into ducted fresh air system and ductless fresh air system. The ducted fresh air system consists of a new fan and duct fittings. The outdoor air purified by the new fan is introduced into the room, and the indoor air is discharged through the duct. The ductless fresh air system consists of fresh air fans, which also purify outdoor air and introduce it into the room.
