## Abstract

The subject of the present application is a composition comprising a lubricant based on polyol esters (POEs) or PVE and a refrigerant F comprising from 1 to 99% by weight of trans-1,3,3,3-tetrafluoropropene (trans-HFO-1234ze) and from 1 to 99% by weight of 1,1,1,3-tetrafluoroethane. The subject of the present application is also the use of said composition in refrigeration, air conditioning and heat pumps.
