Do you want to install a fresh air system? How to install it is better? How to install fresh air system is better.

1. Do you want to install fresh air system? Must be installed. Because the fresh air system can not only ventilate, but also adjust the temperature and humidity of the air entering the room, which makes us feel more comfortable indoors. It can also adsorb and filter the formaldehyde produced by the renovation of new houses, which has gradually become a necessary choice for modern homes.

2. How to install it is better:

(1) On-site positioning: Before system installation, it is necessary to conduct on-site positioning, confirm the installation scheme, and confirm the positions of equipment, tuyeres and controllers. , and confirm the return air way, pipe layout and direction.

(2) Foundation finishing: Foundation finishing operations include opening, grooving, frame cutting, wall penetration, beam penetration and floor penetration. Before installation, it is necessary to confirm which walls in the house can be perforated, and the installation holes should not be opened on beams, columns and load-bearing walls that are dangerous to the safety of the building structure. If it is a new house, it is best to consult whether the property can be perforated first.

(3) Installation of indoor fresh air main engine: The installation position of the main engine of fresh air system should consider factors such as maintenance, noise influence, air intake quality, etc. The installation position of the main engine should be far away from the kitchen and other areas with heavy oil smoke and high humidity, and the hoisting should be stable, and the hanger used should be ensured to have enough strength to bear the weight of the main engine. After the host is installed, it is best to wrap it with plastic wrap to prevent dust.

(4) Pipeline installation: During pipeline installation, anti-vibration measures should be taken at the joint with the hard connection port of the host computer. The connection with the main engine adopts soft connection, and the diameter is changed to prevent vibration. When two pipelines cross, elbows should be used for bridging, and soft joints are not allowed. Try not to use a 90-degree elbow for the pipeline elbow, but use two 45-degree elbows, and try to use an oblique tee for the tee to minimize wind resistance. Pipeline connection must be properly treated for air leakage, and special glue must be used for pipeline connection. The outdoor tuyere and the hole of the external wall should keep the slope of 1: 100, and be rainproof to avoid rainwater from flowing backwards. When installing the fresh air outlet, the outdoor rain cover should be installed firmly, the hole edge should be sealed with glass glue, and the indoor tuyere should be installed tightly and firmly. The fresh air system can choose the form of top air supply or ground air supply. The top air supply pipeline adopts round pipe, and the ground air supply pipeline adopts flat pipe to minimize the wind pressure loss.

(5) Installation of air outlet: The distance between the air inlet and the air outlet of the fresh air system is too close, which will lead to the outdoor fresh air being exhausted before it completely reaches the room. The distance between the outdoor air inlet and outlet should be greater than 1000mm, so as to avoid the fresh air just entering the room being immediately exhausted.

(6) Controller installation: the wiring is firm, the panel installation position is reasonable, and the technology is beautiful.

(7) Commissioning acceptance: power-on commissioning acceptance, to confirm whether the main engine is running normally, whether the pipeline is fixed with the main engine without vibration, whether the pipeline connection is sealed, whether the air volume and noise are normal, and then deliver it to customers for use. With the rise of hardcover rooms and people's constant concern about air quality, fresh air system has gradually entered thousands of households. Only by purchasing reliable fresh air system equipment and reasonably arranging the installation pipes can we finally ensure the effective air purification effect.
