Nowadays, with the ability to purify indoor air efficiently, it can also provide a continuous supply of fresh air to the interior. The fresh air system can be said to have become the strength of the current empty net industry. In particular, when the smog is frequent, the choice of the fresh air system is a method that cannot be done, but the choice of the fresh air system has become the most effective method. For the fresh air system, unlike other air purification equipment, the fresh air system needs to be properly selected and installed before it can be used. Therefore, many people are not very familiar with the fresh air system, so the small surface, Let's build a new wind and come to talk to you about the relationship between wind speed and noise of the fresh air system, so that everyone can understand the selection criteria of the fresh air system air outlet for the fresh air system. The relationship between wind speed and noise in the fresh air system: The working principle of the fresh air system is to supply air to various rooms in the room by purifying the fresh air outside by using special equipment on one side of the room, through a special air supply duct or a micro-positive pressure. At the same time, the air is exhausted to the outside through the special exhaust equipment on the other side, so that the indoor air is in and out, forming a "new wind flow wind field" principle to meet the needs of indoor ventilation and ventilation. In the case of air supply and exhaust, the flow of air is not called wind speed. The speed of the wind is usually related to the diameter of the pipe. If the wind speed is too large, it will directly lead to wind drying. Excessive situation arises, affecting the experience. Standard for wind speed of new fresh air system: Generally speaking, in an air-conditioned room, the noise of the air conditioning system needs to be controlled between 40 and 50 dB (A), that is, the corresponding NR (or NC) number is 35 to 45 dB (A). According to the design specifications, to meet this design specification, the wind speed of the allowable value of the wind is 4 to 7 m / s, and the wind speed of the branch pipe is 2 to 3 m / s. The return air outlet is usually located at the top of the house, and the wind speed is 4~5m/s. When the air return is located at the bottom of the house, the wind speed is 3~4m/s in places where people do not move frequently. Return wind speed is 1.5~2m/s Fresh air system wind speed adjustment: There are many ways to adjust the wind speed of the fresh air system, but the most effective one is the choice of the pipeline. By rationally selecting the pipeline, it is possible to reasonably calculate the use of the pipeline according to the actual situation and carry out the wind speed. The choice of fresh air system piping is very important.
