Noise reduction of a water cooler equipment (chiller)
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2011, Vol 8, Issue 1
Abstract
The chilling equipments of air conditioning installations – located on the flat roof – represent the sources of noise which can cause acoustical discomfort to the habitants from the neighborhood buildings. The dissertation presents the initials results of noise level measurements due to the water cooler equipment (chiller) mounted on the flat roof in 18 Jules Michelet Str. – Bucharest, technical principle solutions to decrease this noise and the final results. Was proposed a constructive solution on THE PROPAGATION PATH, a certain CHILLER SHIELDING by means of sandwich panels. By mounting this acoustical insulating panels was obtained a noise level reduction with 19 dB near the chiller, so the noise level propagated on the front of the building located in Magheru Bd. entered in the admissible limit of 50 dB(A), as specified in STAS 10009-88.
