Fresh air system
The fresh air system is an independent air treatment system consisting of a supply air system and an exhaust air system. It is divided into a ducted fresh air system and a ductless fresh air system. The pipeline fresh air system consists of new fans and pipe fittings. The new air is used to purify the outdoor air and is introduced into the room, and the indoor air is discharged through the pipeline. The non-pipe fresh air system is composed of new fans, and the outdoor air is also purified by the new fan. Relatively speaking, the pipeline fresh air system is more suitable for industrial or large-area office areas due to the large amount of engineering, and the non-pipe fresh air system is more suitable for home use because of its convenient installation. In 1935, after many attempts, Auston 发明 invented and manufactured the world's first heat exchange equipment that can filter air pollution, also known as the fresh air system.
