There is a saying in the fresh air industry, "three points to see the machine, seven points to see the installation", if you want the fresh air system to be effective, it is inseparable from the installation method according to local conditions. Xiaobian has seen such a case on the network, a family installed a fresh air system, but as long as the fresh air system is opened, the air quality test of his master bedroom will become worse than not open, which makes him very upset and depressed. So he invited a professional testing team to check their home, and the result was that the master bedroom was directly negative pressure, and the outdoor polluted air was directly poured back... The main reason is the design and construction of the original installation of the pipe distribution problem, did not take into account the reasonable distribution of air supply according to the size of different rooms, and eventually led to dirty air back, coupled with neglect of maintenance after installation, the pipeline has been polluted, fresh air led to secondary pollution at home.

From this case, we can find that choosing the right fresh air system is not enough, and a professional installation team must reasonably install it in order to reasonably play its maximum role.

So what do you need to pay attention to correctly installing the fresh air system?

01, site positioning

Equipment, tuyere, controller and other location and return air mode, pipeline layout, direction confirmation, that is, program design, in the program design to fully consider a variety of factors, such as avoiding the central air conditioning of the pipeline, where can not open holes, if not sure, need to consult the property.

02, pipeline installation

The air pipe layout is reasonable to minimize the loss of wind pressure, the piping principle of the fresh air system is to shorten the pipeline as far as possible, reduce branch pipelines, avoid complex local components, mainly save materials and reduce local wind resistance, and avoid right-angle installation of the pipeline as far as possible. The connecting pipe fittings can use Y-shaped oblique tee, or use two 45-degree elbows to gently and excessively.

03, host and pipeline connection

In order to ensure the air volume, the length of the straight pipe section connected to the host is more than 1m, and it is best not to use the reducer and the tee branch pipe within 1m. The soft connection between the host and the round pipe. The soft connection between the air duct and the joint needs to be reinforced with a pipe hoop to ensure that the air does not fall off and does not leak.

04, tuyere installation

Indoor and outdoor air inlet and outlet installation, installation firm, neat and beautiful. It should be noted that it is necessary to avoid the inlet and outlet distance is too close, which will directly lead to the fresh air does not fully reach the room will be discharged, generally take the diagonal installation method, if there are other factors, then the inlet and outlet distance is at least 1 meter above. Avoid the fresh air that has just entered the room being expelled immediately.

05. Installation of host control panel

Adopt the principle of proximity, the wiring is firm, and the process is beautiful. Of course, if you want to decorate the fresh air system after the decoration, then you can choose a wall-mounted fresh air system or a cabinet fresh air system, but it should be noted that generally these two fresh air systems are only for the fresh air needs of a space area.

The existence of the fresh air system may not make people directly feel the changes in life, but the convenience and effect brought by it require long-term life accumulation to compare the results. Professional things to find professional people to do, professional design and construction, in order to ensure the efficient and normal use of fresh air system. Have a lot of experience and technology to provide a strong guarantee for the design and construction of fresh air system.
