CA 2573233

A system is provided for attenuating tonal acoustic noise associated with a single positive displacement compressor (102), or multiple positive displacement compressors (102, 104) proximately located from each other. A controller (110) selectably controls the rotational speed and the frequency of operation of each of the compressors (102, 104). The controller (110) controls the rotational speed of the compressors (102, 104) about a predetermined rotational speed, in a random manner, within the pre-selected speed band to reduce the magnitude of the central tonal acoustic frequency of the pressure pulsations and disperse the sound power over a wider acoustic bandwidth.

Système servant à atténuer le bruit acoustique associé à un ou plusieurs compresseurs à déplacement positif (102, 104) placés à proximité les uns des autres. Un contrôleur (110) contrôle de façon sélective la vitesse de rotation et la fréquence d'opération de chacun de ces compresseurs (102, 104). Ce contrôleur (110) contrôle la vitesse de rotation des compresseurs (102, 104) à une vitesse de rotation prédéterminée, de manière aléatoire, à l'intérieur de la plage de vitesses présélectionnée, afin de limiter l'intensité de la fréquence acoustique sonore médiane des pulsations de pression et de disperser la puissance du son sur une largeur de bande acoustique plus large.
