Matters needing attention in installing fresh air system

During installation, keep the host position of fresh air system level and firm; Fans and air ducts should be equipped with flexible pipes or rigid pipes according to actual installation conditions; The fresh air outlet and exhaust outlet are generally installed diagonally. Specific precautions are as follows:

1, keep the host position of fresh air system level and firm. If it is a ducted central fresh air system, it is generally installed on the ceiling of the kitchen or bathroom, which should be determined according to the actual situation on site.

2. The fans and air ducts of fresh air system should be flexible or rigid pipes according to the actual installation conditions, which are generally used in combination. It is not allowed to install a single pipe in disorder, and the pipe diameter should be consistent with the import and export dimensions of the fans. If a hose is used, it should be installed with a certain tightness to avoid deformation.

3. In the installation process of the ducted central fresh air system, if you encounter a wall or beam that is not allowed to open holes in the property, you should use the beam. At the same time, when the pipeline needs to change direction, the angle should be greater than 90 as far as possible, and the pipeline laying should be as short as possible. It is forbidden to lay useless pipelines, because the longer the pipeline, the greater the wind loss at the end.

4. The fresh air outlet and the exhaust outlet are generally installed diagonally, so as to ensure the maximum distance between the two outlets and avoid the fresh air that has just entered the room being directly discharged from the exhaust outlet. At the same time, the tuyere exposed to the outside should be equipped with a rain cap and installed effectively to avoid the direct backflow of rainwater.
