Title (EN) SCREW COMPRESSOR, AIR CONDITIONING DEVICE AND REFRIGERATING DEVICE
(FR) COMPRESSEUR À VIS, DISPOSITIF DE CLIMATISATION ET DISPOSITIF DE RÉFRIGÉRATION
(ZH) 螺杆压缩机、空调装置及制冷装置
Abstract:
(EN) Disclosed are a screw compressor, and an air conditioning device and a refrigerating device comprising the screw compressor, wherein the screw compressor comprises a compressor body (10); a supplementary air channel is arranged on the compressor body (10); and the supplementary air channel is provided with at least two supplementary air holes (201) in communication with a compression cavity. In the screw compressor, at least two supplementary air holes (201) are provided, and under the condition where there is limited space for arranging the supplementary air holes (201) on the compressor body, the diameter of each supplementary air hole (201) is relatively small. Providing a relatively large number of supplementary air holes (201) and providing same with relatively small diameters are beneficial for reducing airflow pulsations, so as to reduce noise during an air supplementation process.
(FR) L'invention concerne un compresseur à vis, et un dispositif de climatisation et un dispositif de réfrigération comprenant le compresseur à vis, le compresseur à vis comprenant un corps de compresseur (10); un canal d'air supplémentaire est disposé sur le corps de compresseur (10); et le canal d'air supplémentaire est pourvu d'au moins deux trous d'air supplémentaires (201) en communication avec une cavité de compression. Dans le compresseur à vis, au moins deux trous d'air supplémentaires (201) sont ménagés, et dans la situation où il y a un espace limité pour agencer les trous d'air supplémentaires (201) sur le corps de compresseur, le diamètre de chaque trou d'air supplémentaire (201) est relativement petit. La fourniture d'un nombre relativement important de trous d'air supplémentaires (201) et leur fourniture avec des diamètres relativement petits sont bénéfiques pour réduire les pulsations d'écoulement d'air, de façon à réduire le bruit pendant un processus de supplémentation en air.
(ZH) 一种螺杆压缩机、包括该螺杆压缩机的空调装置及制冷装置,螺杆压缩机包括机体(10),机体(10)上设置补气通道,补气通道具有至少两个与压缩腔连通的补气孔(201)。该螺杆压缩机的补气孔(201)的数量为至少两个,在机体上能够用于设置补气孔(201)的空间有限的情况下,每个补气孔(201)的孔径较小;数量较多且孔径较小的补气孔(201)利于减小气流脉动,从而减小补气过程中的噪音。
