Precautions for installation of fresh air system How to clean and maintain fresh air system?

Fresh air system is a common ventilation system in life. If you want to use the fresh air system, you need to install it and pay attention to cleaning and maintenance. What are the precautions for the installation of fresh air system? How to clean and maintain on weekdays? Today, we will talk about fresh air system with Bian Xiao.

A, the installation of fresh air system matters needing attention

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, for the tuyere exposed outdoors, a rain cap should be added and installed effectively to avoid the direct backflow of rainwater!

Second, how to clean and maintain the fresh air system

First of all, the tuyere and filter screen are cleaned. Because the domestic fresh air system will absorb a lot of dust in the air during operation, it will cause dust to accumulate in the tuyere for a long time, which is not good for the beauty of the fresh air system and human health. Therefore, in order to keep the fresh air system clean, it is best to clean the dust at its tuyere, especially the dust on the filter screen, so as to avoid blocking the outlet of exhaust and air supply and affecting the efficiency of exhaust and air supply.

Secondly, the inspection of the joint between the air duct and the host machine, because the air duct is easy to cause dust accumulation after long-term use, which will block the pipeline and lead to poor fresh air effect, so it is best to have professionals regularly check and clean the air duct of the home fresh air system. In addition, a large amount of dust will accumulate when the wiring board of the household fresh air system is connected to the power cord for a long time, so it is best to let professionals visit the house regularly.

Finally, the air tightness of the control panel and pipeline is also the scope of inspection. Through the inspection of these two parts, some potential safety hazards can be eliminated, the damage of parts can be found in time, and repairs and maintenance can be carried out in time.

It can be seen that the installation of fresh air system needs to pay attention to related matters, such as keeping the position of the main engine of fresh air system horizontal 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.
