How to reduce the noise of closed cooling tower

  Some customers feel that the noise is a bit loud when using a closed cooling tower. The sources of noise in a closed cooling tower are: water splashing, fan noise, and water pump vibration. Sometimes the vibration range of its noise may involve the surrounding 30 to 50m, which shows that the power of the closed cooling tower noise is great. So how to reduce the noise of closed cooling towers, trlon will explain to you.Q42Cooling tower noise reduction treatment manufacturer

  The main way of noise transmission is through the air. If the sound interference is increased in the surroundings, the opposite sound will be refracted and reflected multiple times. As the number of reflections and distance increase, the decibel of the sound will gradually decrease. The sound of water splashing, fan noise, and water pump vibration are different, and the frequency of noise is also different. Below we propose solutions one by one.Q42Cooling tower noise reduction treatment manufacturer

  Fan noise: The higher the fan speed, the greater the noise. Increase the air volume and reduce the speed to reduce the noise. If the budget is sufficient, it can replace the large blades with low speed.Q42Cooling tower noise reduction treatment manufacturer

  Pump noise: Install sound-proof cotton outside the pump to reduce noise and not affect heat dissipation.Q42Cooling tower noise reduction treatment manufacturer

  Water sprinkling sound: only one side of the air inlet of the cross-flow cooling tower will reduce the noise transmission; the bottom of the counterflow cooling tower will have an air inlet grille around the bottom, and the sound of water sprinkling and the air inlet will form convection, which will also reduce noise spread.Q42Cooling tower noise reduction treatment manufacturer
