Fresh air system mainly consists of three parts: fresh air fan, pipes and air outlet or air supply hood.
Structural features
Fresh air fan: The core function of the fresh air fan is to extract air from the outside and transport it to the room through pipes after filtering. Fresh air fans are usually installed outdoors to purify the air through filters, activated carbon and other devices.
Pipeline: The pipeline connects the fresh air fan and the air outlet to ensure smooth air transportation. The design and layout of the pipeline directly affect the efficiency and effect of the fresh air system, and usually requires reasonable planning to cover all areas of the room.
Air outlet or air supply hood: Responsible for delivering fresh air into the room. The air outlet can be installed on the wall, ceiling and other locations to ensure that the air is evenly distributed to each room.
