Why does the air conditioning system need to be processed to eliminate noise

In addition to the air-conditioning engineering requirements for temperature, humidity, wind speed, and air cleanliness, the vibration and noise of air-conditioning equipment (fans, chillers, water pumps, cooling towers, etc.) due to mechanical movement, in addition to the surrounding environment The pollution caused by noise will also be transmitted to the air-conditioned room through the air duct, wall, floor and other parts. Increase the noise in the room, and the large mechanical noise and environmental noise will make people irritable and lose concentration. Improve the quality and efficiency of office and rest. Therefore, in addition to noise reduction and vibration reduction for fans or other air-conditioning equipment, noise reduction treatment is also required on the air duct to reduce the noise transmitted through the air duct.

For fans, water pumps, chillers, cooling towers and other equipment, in addition to low-noise fans, vibration damping and isolation measures have also been taken. For the computer room, noise-absorbing walls and doors should also be used as much as possible. Reduce the transmission of noise. A muffler must be installed on the air-conditioning air duct to eliminate the noise generated by the equipment from being transmitted to the air-conditioned room.

According to different structures and different noise reduction principles, there are many types of mufflers used in air conditioning projects. Commonly used are impedance composite mufflers, tube mufflers, micro-perforated plate mufflers, chip mufflers, folded plate mufflers, muffler elbows, Muffler pipe section, etc.
