An ester blend, including an ester having neopentylglycol and a source of 2- ethylhexanoic acid as its reactive components and an ester having pentaerythritol and a source of 2-ethylhexanoic acid as its reactive components, is especially effective as a lubricant for chlorine-free fluorocarbon refrigerant heat transfer fluids, particularly Refrigerant 134a (1,1,1,2-tetrafluoroethane).
L'invention concerne un mélange d'esters, comprenant un ester présentant du néopentylglycol, et une source d'acide 2-éthylhexanoïque comme composants réactifs et un ester présentant du pentaérythritol et une source d'acide 2-éthylhexanoïque comme composants réactifs. Ce mélange est particulièrement utile comme lubrifiant pour les fluides de transfert thermique réfrigérants de fluorocarbone sans chlore, en particulier le réfrigérant 134a (1,1,1,2-tétrafluoroéthane).
