Anonymous users2024-01-23First of all, a low-noise fan should be chosen. A volute-free rear fan box has the characteristics of high reliability and stable pressure, which is more suitable for kitchen fume exhaust; The fan has no volute, and there will be no interference noise between the impeller and the worm tongue, and it has the characteristics of low noise; The fan box has the function of sound insulation and noise reduction, and the noise of the fan box itself is very low. Although the noise of the multi-wing air conditioner fan box is low, it is not suitable for kitchen fume exhaust.
A large number of engineering examples have proved that the performance of the fan is unstable and unreliable in the exhaust of oil smoke, which often leads to the failure of the entire ventilation system.
The use of mufflers to eliminate exhaust noise is a common measure. Fans with large air volume are mostly low-frequency noise, and the amount of noise muffled through the muffler is limited. In the high humidity environment and oil smoke, the muffler has a great impact, and the muffler function will deteriorate over time.
Practice has proved that the effect of the muffler elbow is better than that of ordinary mufflers.
Acoustic screens are an effective way to block noise transmission. In the catering industry, the fume ventilation equipment is often installed on the roof platform of the building. The noise emitted by the device is transmitted to the surrounding area without obstacles.
Acoustic screens are often an effective measure for noise control. For example, install a soundproof screen, because the soundproof screen is easy to build. The key to success is to design and calculate effective vibration and noise reduction measures for kitchen noise.
