Central air conditioning cooling tower noise control solution
If the normal operation noise of the central air-conditioning cooling tower is too loud, the noise can be appropriately reduced by adjusting the refrigeration system status, fan motor speed, etc., or by adding sound absorption and noise reduction facilities. If it is abnormal noise, it is necessary to find the cause of the abnormal operation noise and eliminate the abnormal situation in a targeted manner. The following Saiweis sound insulation and noise reduction manufacturer will explain the noise treatment plan of the central air-conditioning cooling tower in detail.
Central air-conditioning cooling tower noise control solution
1. Sound insulation cover Add a sound insulation cover to the noise source of the central air-conditioning cooling tower to prevent noise leakage.
2. Muffler controls the noise of the exhaust fan inlet and outlet of the central air-conditioning cooling tower. A special muffler can be installed at the inlet and outlet of the cooling tower. For cooling towers with prominent inlet and outlet noise, this method has a significant noise reduction effect;
3. Sound insulation barrier When sound waves encounter obstacles during propagation, three phenomena will occur: reflection, transmission and diffraction. The sound barrier is a facility inserted between the sound source and the sound receiving point to block and absorb the direct sound waves from the sound source to the sound receiving point, so that some sound waves are blocked and reflected, and some sound waves are absorbed and attenuated and then reach the sound receiving point through additional attenuation forms such as screen body transmission (extremely small) and screen top diffraction, so as to reduce the noise impact of the sound receiving point and achieve the purpose of noise reduction.
4. Falling water noise reduction device Before the falling water of the central air-conditioning cooling tower directly hits the water surface, the falling water first passes through the transition of energy dissipation forms such as silent rubbing, viscous deceleration, flow separation, and evacuation and scattering on the inclined surface to achieve the treatment effect of reducing the falling water impact noise. It is a treatment technology for the source of the sound source in the tower.
5. Shock absorber and rubber flexible connection The damping spring shock absorber is installed between the foot of the central air-conditioning cooling tower and the ground, and the rubber flexible joint is installed in the pipeline, which can effectively isolate the vibration transmission and prevent noise radiation.
