Expected Effect The noise of the units will be significantly reduced, and the indoor and outdoor acoustic environment will meet the standards for public places. Obvious roaring and wind noise will be eliminated without affecting the normal use of the Youth Palace. The ventilation and heat dissipation of the system will remain normal, and the equipment will operate safely and stably.

The main noise sources include noise from the rooftop vents, reactors and fans at the reactor room vents. Noise from reactors (transformer-type equipment) mainly originates from core vibration caused by magnetostriction of silicon steel sheets. Cooling fans also generate noise at specific frequencies, and vibration of the unit itself transfers to cooling devices, exacerbating the noise. The control approach is to comprehensively adopt sound insulation, sound absorption and noise elimination measures, and formulate an integrated control scheme based on the principles of noise propagation.

Scheme Features -Adopt comprehensive control mainly including vibration damping, sound insulation, sound absorption and noise elimination. -Targetedly solve the typical low-frequency vibration and noise problems of heat exchange pump houses. -Simple construction, short construction period and little impact on the daily life of residents in the community.
