Title (EN) REFRIGERATOR OIL COMPOSITION FOR HYDROFLUOROCARBON REFRIGERANT
(FR) HUILE REFRIGERANTE POUR REFRIGERANT A BASE D'HYDROFLUOROCARBONE
Abstract:
(EN) A refrigerator oil composition for a hydrofluorocarbon (hydrogen-containing flon) refrigerant, characterized by comprising a polyoxyalkylene glycol derivative and/or a specified polyester compound and added thereto (a) a partial fatty acid ester of a polyhydric alcohol and (b) a phosphate compound and/or a phosphite compound. It is excellent in the compatibility with a hydrogen-containing flon refrigerant, such as flon (134a), and in the lubricity, and utilizable as a refrigerator oil useful for an improvement in the resistance to abrasion, particularly between an aluminum material and a steel material.
(FR) Huile réfrigérante pour un réfrigérant à base d'hydrofluorocarbone (fluorocarbone hydrogéné), caractérisée par le fait qu'elle comprend un dérivé de polyoxyalkylène glycol et/ou un composé de polyester spécifique, avec l'addition (a) d'un ester d'acide partiellement gras d'un alcool polyhydrique et (b) d'un composé de phosphate et/ou d'un composé de phosphite. Cette huile présente une excellente compatibilité avec un réfrigérant à base de fluorocarbone hydrogéné, tel que le fluorocarbone 134a, ainsi que d'excellentes caractéristiques de lubrification, et peut être utilisée comme huile réfrigérante améliorant la résistance à l'abrasion, notamment entre l'aluminium et l'acier.
