2. Control the wind speed of air duct and air outlet according to the noise specification to meet the room noise requirements
3. Select low-noise water pump and fan, and make the water pump and fan run near the efficiency point
4. Non combustible soft materials shall be filled at the supports and hangers of the pipeline and through the wall for vibration reduction
Suspended butterfly valve electric butterfly valve shall be used for hoisting equipment with large vibration
5. The inner surface of the air conditioning room is attached with sound absorption data and sound absorption orifice plates, and the machine room door is silenced and closed, so that the wall has sound absorption, etc. 6. In the air conditioning system, the air conditioning unit should use the butterfly valve electric butterfly valve, and choose the butterfly valve electric butterfly valve with different deflections according to the unit power and device location, and the high-power equipment can use the 40MM deflection butterfly valve electric butterfly valve, 25MM conventional butterfly valve electric butterfly valve can be used for small power air conditioning host. Damping valve refers to the method of dissipating the energy of equipment vibration in the damping layer as much as possible when equipment vibrates. Damping refers to a function of blocking the relative movement of objects and converting the movement energy into heat energy or other energy that can be dissipated
