Abstract
(EN)
Disclosed are an oil separation device (1283) and a condenser (130-1130) with an oil separation function, and a refrigeration system (100, 1200) using same. The oil separation device (1283) or the condenser (130-1130) comprises: a shell (201, 1301) comprising an oil separation cavity (315, 1315), a first refrigerant inlet (221, 1221), a second refrigerant inlet (222, 1222), a first flow guide channel (445-2145), and a second flow guide channel (446-2146), wherein refrigerant gas flowing through the two flow guide channels can be mixed. When the refrigeration system (100, 1200) comprises two compressors (108, 1208, 109, 1209) with different displacements, the requirement of filtering and separating a gaseous refrigerant and lubricating oil can be met without the need for designing the size of the oil separation chamber (315, 1315) in accordance with large-displacement compressors (109, 1209), and the size is small.
(FR)
L'invention concerne un dispositif de séparation d'huile (1283) et un condenseur (130-1130) ayant une fonction de séparation d'huile, et un système de réfrigération (100, 1200) les utilisant. Le dispositif de séparation d'huile (1283) ou le condenseur (130-1130) comprend : une enveloppe (201, 1301) comprenant une cavité de séparation d'huile (315, 1315), une première entrée de fluide frigorigène (221, 1221), une seconde entrée de fluide frigorigène (222, 1222), un premier canal de guidage d'écoulement (445-2145), et un second canal de guidage d'écoulement (446-2146), un fluide frigorigène gazeux s'écoulant à travers les deux canaux de guidage d'écoulement pouvant être mélangé. Lorsque le système de réfrigération (100, 1200) comprend deux compresseurs (108, 1208, 109, 1209) ayant différentes cylindrées, l'exigence de filtration et de séparation d'un fluide frigorigène gazeux et d'une huile lubrifiante peut être satisfaite sans la nécessité de concevoir la taille de la chambre de séparation d'huile (315, 1315) selon des compresseurs à grande cylindrée (109, 1209), et la taille est petite.

一种油分离装置(1283)和一种具有油分离功能的冷凝器(130-1130),以及使用其的制冷系统(100,1200),其中油分离装置(1283)或冷凝器(130-1130)包括:壳体(201,1301),包括油分离腔(315,1315);第一制冷剂入口(221,1221)和第二制冷剂入口(222,1222);第一导流通道(445-2145)和第二导流通道(446-2146),流经两个导流通道的制冷剂气体能够混合。当制冷系统(100,1200)包括两个排量不等的压缩机(108,1208,109,1209)时,无需按照大排量压缩机(109,1209)设计油分离腔(315,1315)尺寸,就能满足气态制冷剂和润滑油过滤分离的要求,使尺寸较小。
