Abstract

A composition including a lubricant based on polyol esters (POEs) or polyvinyl ether (PVE) and a refrigerant F including from 1 to 99% by weight of 2,3,3,3-tetrafluoropropene (HFO-1234yf) and from 1 to 99% by weight of trans-1,3,3,3-tetrafluoropropene (trans-HFO-1234ze). Also, the use of the composition in refrigeration, air conditioning and heat pumps.

Claims

exact text as granted — not AI-modified
1 . Composition comprising at least one lubricant comprising polyol esters or polyvinyl ether and a refrigerant F comprising from 1 to 99% by weight of 2,3,3,3-tetrafluoropropene (HFO-1234yf) and from 1 to 99% by weight of trans-1,3,3,3-tetrafluoropropene (trans-HFO-1234ze). 
     
     
         2 . Composition according to  claim 1 , characterized in that the refrigerant F comprises from 5 to 70% by weight of 2,3,3,3-tetrafluoropropene (HFO-1234yf) and from 30 to 95% by weight of trans-1,3,3,3-tetrafluoropropene (trans-HFO-1234ze). 
     
     
         3 . Composition according to  claim 1 , characterized in that the refrigerant F comprises from 25 to 55% by weight of 2,3,3,3-tetrafluoropropene (HFO-1234yf) and from 45 to 75% by weight of trans-1,3,3,3-tetrafluoropropene (trans-HFO-1234ze). 
     
     
         4 . Composition according to  claim 1 , characterized in that the polyol esters are obtained from polyols having a neopentyl backbone. 
     
     
         5 . Composition according to  claim 4 , characterized in that the polyol having a neopentyl backbone is selected from the group consisting of neopentyl glycol, trimethylolpropane, pentaerythritol and dipentaerythritol. 
     
     
         6 . Composition according to  claim 1 , characterized in that the polyol esters are obtained from a linear or branched carboxylic acid containing from 2 to 15 carbon atoms. 
     
     
         7 . Composition according to  claim 1 , characterized in that the polyol esters comprise between 10 and 50% by weight of the composition.
