(EN) SILENCER FOR A HEATING, VENTILATION, AND AIR CONDITIONING SYSTEM
(FR) SILENCIEUX POUR SYSTÈME DE CHAUFFAGE, DE VENTILATION ET DE CLIMATISATION
Abstract
(EN)
The present application discloses a silencer for a heating, ventilation, and air conditioning system comprising a silencing channel having an outlet and an inlet, such that airflow flows in from the inlet and flows out from the outlet, and a check valve disposed in the silencing channel. The check valve has a bivalve butterfly structure, such that airflow in the silencing channel flows unidirectionally to the outlet after flowing through the check valve from the inlet, instead of flowing from the outlet to the inlet after flowing through the check valve. The present application also discloses a compressor, wherein at least a portion of the exhaust channel of the compressor is constructed as the aforementioned silencing channel and in which a check valve having a bivalve butterfly structure is disposed.

La présente invention concerne un silencieux destiné à un système de chauffage, de ventilation et de climatisation, le silencieux comprenant un canal de suppression de bruit comportant une sortie et une entrée, de sorte qu'un écoulement d'air entre à travers l'entrée et sorte à travers la sortie, et un clapet anti-retour disposé dans le canal de suppression de bruit. Le clapet anti-retour comporte une structure à papillon à deux clapets, l'écoulement d'air dans le canal de suppression de bruit coulant ainsi de façon unidirectionnelle vers la sortie après avoir coulé à travers le clapet anti-retour à partir de l'entrée, au lieu de couler de la sortie vers l'entrée après avoir coulé à travers le clapet anti-retour. La présente invention concerne également un compresseur dans lequel au moins une partie du canal d'échappement du compresseur prend la forme du canal de suppression de bruit mentionné ci-dessus et dans lequel un clapet anti-retour, présentant une structure en papillon à deux clapets, est disposé.
