Silencer type inventory and introduction:

Type 1: the resistance muffler it is mainly through the sound absorption material to reduce the noise, the sound absorption material is installed in the airflow flow of the pipeline, so that the air conditioning in the work, the noise will be absorbed and reduced. Why does it have this ability? This is because the sound-absorbing material is porous and loose. When sound waves enter the void, they cause a small vibration with the material, which blocks some of the sound energy. It is suitable for high - frequency noise and medium - frequency noise air conditioning, low - frequency noise is not so good effect.

Type 2: resonance muffler

Because low frequency noise is really more difficult to absorb, only by absorbing material is far from enough, a lot of people will also increase several layers of absorbing material, in fact, the effect is not much good, also not practical, that in order to improve the low-frequency noise absorption effect, can choose what kind of air conditioning muffler? The resonant muffler is connected with the resonant cavity through the opening of the pipe, and the air column in the hole and the air in the cavity constitute the elastic resonance system. When the air conditioning starts to work, the air column in the hole will produce strong friction, so as to achieve the purpose of noise reduction.

Type 3: resistant muffler

This is through reflection phenomenon to achieve the role of noise reduction, but also more suitable for low noise. It is mainly connected by a tube and a small chamber. When the air conditioning starts to work, the section of the duct changes suddenly, causing the sound wave to reflect back to the opposite direction of the sound source. This kind of muffler is not suitable for use in small space. But because this kind of air conditioning muffler does not need to use sound-absorbing material, it is not affected by high temperature and corrosive gas, and its service life is relatively high.
