3,3,3-TRIFLUOROPROPENE COMPOSITION

摘要

A composition including a polyol ester (POE) or PVE lubricant and a refrigerant including 3,3,3-trifluoropropene. The refrigerant may also include 2,3,3,3-tetrafluoropropene and trans-1,3,3,3-tetrafluoropropene. The POEs may be obtained from polyols which have a neopentyl backbone, such as neopentyl glycol, trimethylol propane, pentaerythritol and dipentaerythritol. Also, the use of said composition for refrigeration, air-conditioning, and for heat pump.
