The fresh air system is an independent air handling system composed of an intake system and an exhaust system. It is divided into two types: ductless fresh air system and ducted fresh air system. The ductless fresh air system consists of a new fan, and the fresh air is also introduced into the room after purification. The ducted fresh air system is composed of a new fan and duct accessories. The outdoor air is purified by the new fan and introduced into the room, and the indoor air is discharged through the duct. Relatively speaking, the ducted fresh air system is more suitable for industrial or large office areas due to the large amount of engineering, while the ductless fresh air system is more suitable for home use due to its easy installation.
