Central air conditioning room noise control measures
1, walls and ceiling to sound absorption treatment;
2, room doors and Windows with soundproof Windows and doors;
3, air-conditioning host and pump, leg mounting damper spring shock absorber;
4, the engine room the pipeline for vacant, install damping spring hanger shock absorber;
5, inlet and outlet installed single ball-ball rubber soft joints;
6. pipe flow and friction noise such as larger, with sound insulation, sound insulation blanket material and sound insulation of pipes.
Air compressor by a pair of parallel arrangement, mutual engagement of the rotor. Work, a rotor clockwise rotation, a rotor counter-clockwise rotation, in mutual engagement process, the air is compressed to the required pressure, this time will result in 70-100db (a) of the noise. In noise control, you can take the following measures:
1. do a noise enclosures or soundproof rooms will air compressor and isolation. Soundproof room wall and ceiling around with sound-absorbing material, laying out the set to fire into the next part of the glottis, observation of sound observation Windows.
2, air intake section can be equipped with silencers intake manifold.
3, room cooling air intake and coercive force exhaust, intake and exhaust silencers and muffler installed at the Venetian.
4. air compressor motor Office equipped with shock absorber to control vibration noise transmission.
