Abstract

L'invention concerne une pompe à chaleur air-air à faible bruit. La pompe à chaleur air-air à faible bruit comprend un corps (1), un évaporateur (15), une pale de ventilateur centrifuge (3), un compresseur (4), un échangeur de chaleur (5), etc., la pale de ventilateur centrifuge (3) étant montée dans un support dédié (2), et au moyen d'un conduit d'air latéral (22) sur le support de ventilateur centrifuge (2), l'écoulement d'air de la pale de ventilateur centrifuge (3) sort par une face latérale. Du fait que la pale de ventilateur centrifuge (3) peut toujours satisfaire un flux d'air pendant le fonctionnement de la pompe à chaleur air-air et dans l'hypothèse d'une faible vitesse de rotation, des bruits de fonctionnement tels que des vibrations de composants et une perturbation de flux d'air générées lors d'un processus de fonctionnement de la pale de ventilateur peuvent être réduits, et la propagation et la diffusion du bruit sont également fortement réduites au moyen d'un écoulement d'air latéral. En outre, un manchon de guidage d'air (6) est de plus disposé entre l'évaporateur (15) et le support de ventilateur centrifuge (2), un trou de guidage d'air (61) faisant saillie vers le support de ventilateur centrifuge (2) est ménagé sur le manchon de guidage d'air (6), et le trou de guidage d'air (61) et la pale de ventilateur centrifuge (3) sont situés sur la même ligne d'axe. La structure garantit non seulement les avantages d'utilisation de la pale de ventilateur centrifuge (3), mais résout également le problème du centre de l'évaporateur (15) qui est sujet au gel dû à la centralisation d'aspiration d'air de la pale de ventilateur centrifuge (3).
