Title
(EN) LUBRICATING OIL FOR COMPRESSION REFRIGERATORS, WORKING FLUID FOR REFRIGERATORS, AND METHOD FOR LUBRICATING REFRIGERATION SYSTEM
(FR) HUILE LUBRIFIANTE POUR REFRIGERATEURS A COMPRESSION, FLUIDE THERMODYNAMIQUE POUR REFRIGERATEURS ET PROCEDE DE LUBRIFICATION DE SYSTEME DE REFRIGERATION
Abstract
(EN)
A lubricating oil for compression refrigerators which comprises as the base oil (a) a polyether wherein a plurality of hydrocarbon groups are bonded to the oxygen atoms of a residue of a tetrahydric or higher alcohol to form ether linkages, the carbon atoms of the hydrocarbon groups directly bonded to the oxygen atoms being each further substituted with two C1-C8 alkyl groups, and (b) an aromatic compound having a C8-C20 branched alkyl group, or which comprises the above polyether (a) as the base oil and 0.5 to 4.5 wt.% of a polyoxyalkylene; a working fluid for refrigerators comprising the lubricating oil and a hydrofluorocarbon refrigerant; and a method for lubricating a refrigeration system by compressing the refrigerant with the lubricating oil. The lubricating oil can inhibit the deposition in a refrigeration system, and is excellent in lubricating properties, moisture absorption, electrical characteristics and so on.

L'invention concerne une huile lubrifiante destinée à des réfrigérateurs à compression comprenant en tant qu'huile de base (a) un polyéther dans lequel une pluralité de groupes d'hydrocarbure sont liés aux atomes d'oxygène d'un reste d'alcool tétrahydrique ou supérieur pour former des liaisons éther, les atomes de carbone des groupes d'hydrocarbure directement liés aux atomes d'oxygène étant chacun à nouveau substitués par deux groupes alkyle C1-C8, et (b) un composé aromatique présentant un groupe alkyle ramifié C8-C20, ou comprenant le polyéther précité (a) en tant qu'huile de base et 0,5 à 4,5 % en poids d'un polyoxyalkylène; un fluide thermodynamique pour réfrigérateurs comprenant l'huile lubrifiante ainsi qu'un fluide frigorigène hydrofluorocarboné; et un procédé de lubrification d'un système de réfrigération par compression du fluide frigorigène avec l'huile lubrifiante. L'huile lubrifiante peut empêcher le dépôt dans un système de réfrigération et elle présente des propriétés lubrifiantes, des caractéristiques d'absorption d'humidité et électriques excellentes etc..
