Abstract

L'invention concerne un compresseur dans lequel une composante de fréquence de pulsation appropriée d'un fluide peut être suffisamment réduite par un silencieux tandis que la performance du compresseur est assurée. Un compresseur (1) est pourvu d'un mécanisme (4) de compression qui comprime un fluide frigorigène, et d'un silencieux (10) qui réduit la pulsation du fluide frigorigène comprimé par le mécanisme (4) de compression. Le silencieux (10) est pourvu : d'un corps (11) de silencieux qui accepte en son sein un fluide frigorigène provenant du mécanisme de compression ; et d'un couvercle (12) qui forme une cavité (120) présentant une périphérie externe (11S) du corps (11) de silencieux, le couvercle (12) évacuant le fluide frigorigène aspiré depuis l'intérieur du corps (11) de silencieux. Plusieurs ouvertures (11H) traversant dans la direction de l'épaisseur de plaque sont formées dans le corps (11) de silencieux, indépendamment d'un orifice (11P) d'évacuation à travers lequel le fluide frigorigène passe dans la cavité (120) depuis l'intérieur du corps (11) de silencieux. En raison de la relation entre la vitesse du son (C), la superficie en coupe (S) de chacune des ouvertures (11H), l'épaisseur de plaque (L), et le volume (V) de la cavité (120), une résonance de Helmholtz se produit dans des masses d'air (15) situées à l'intérieur des ouvertures (11H) débouchant dans la cavité (120), ce par quoi le son est absorbé.
