The present invention provides compositions that are useful for compatibilizing a conventional, non-polar, compression refrigeration lubricant and a hydrofluorocarbon and/or hydrochlorofluorocarbon refrigerant in a compression refrigeration apparatus. Additionally, these compositions promote efficient return of lubricant from the non-compressor zones to the compressor zones of the aforesaid refrigeration apparatus.

L'invention concerne des compositions utilisées pour assurer la compatibilité d'un lubrifiant de réfrigération à compression non polaire classique et d'un fluide frigorigène hydrofluorocarbone et/ou hydrochlorofluorocarbone dans un dispositif de réfrigération à compression. En outre, ces compositions favorise un retour efficace du lubrifiant depuis des zones de non-compression vers des zones de compression du dispositif de réfrigération susmentionné.
