Title
(EN) ENHANCED METHOD OF LUBRICATION FOR REFRIGERATION COMPRESSORS
(FR) PROCÉDÉ AMÉLIORÉ DE LUBRIFICATION POUR COMPRESSEURS DE RÉFRIGÉRATION
Abstract
(EN)
A refrigeration system includes a compressor for compressing a refrigerant, a condenser for cooling the refrigerant, an evaporator for heating the refrigerant, and a lubrication system for providing a lubricant mist to a movable component of the compressor. The lubrication system includes an ejector arranged in fluid communication with the compressor and the evaporator, wherein the lubricant mist is carried by the refrigerant to the movable component.
(FR)
Système de réfrigération comprenant un compresseur pour comprimer un fluide frigorigène, un condenseur pour refroidir le fluide frigorigène, un évaporateur pour chauffer le fluide frigorigène, et un système de lubrification pour fournir un brouillard de lubrifiant à un composant mobile du compresseur. Le système de lubrification comprend un éjecteur disposé en communication fluidique avec le compresseur et l'évaporateur, le brouillard de lubrifiant étant transporté par le fluide frigorigène vers le composant mobile.
