Abstract

The invention relates to a composition including a polyol ester (POE) or PVE lubricant and a refrigerant F including 3,3,3-trifluoropropene. The invention also relates to the use of said composition for refrigeration, air-conditioning, and for heat pump.

First claim

The invention claimed is:

1. A composition consisting of:
at least one lubricant based on
at least one polyol ester obtained from a polylol having a neopentyl backbone, or
at least one polyvinyl ether;

a refrigerant consisting of 3,3,3-trifluoropropene, 2,3,3,3-tetrafluoropropene, and trans-1,3,3,3-tetrafluoropropene; and
optionally at least one of a compatibilizer, a surfactant, and a solubilizing agent.

2. The composition as claimed in claim 1 , wherein the lubricant is based on the at least one polyol ester obtained from a polyol having a neopentyl backbone.

3. The composition as claimed in claim 1 , wherein the lubricant is based on the at least one polyol ester, and wherein the at least one polyol ester is obtained from linear or branched carboxylic acid having from 2 to 15 carbon atoms.

4. The composition as claimed in claim 1 , wherein the lubricant is based on the at least one polyol ester, and wherein the at least one polyol ester represents between 10% and 50% by weight of the composition.

5. The composition as claimed in claim 1 , wherein the polyol having the neopentyl backbone is selected from the group neopentyl glycol, trimethylol propane, and dipentaerythritol.

6. The composition as claimed in claim 1 , wherein the lubricant is based on the at least one polyol ester, and wherein the at least one polyol ester is a pentaerythritol ester.

7. The composition as claimed in claim 1 , wherein the lubricant is based on the at least one polyol ester, and wherein the at least one polyol ester comprise between 0 and 5 relative mol % of CH 2 —OH units relative to the —CH 2 —O—(C═O)-units.

8. The composition as claimed in claim 1 , wherein the lubricant has a viscosity of from 1 to 1000 centiStokes at 40° C.

9. The composition as claimed in claim 1 , wherein the lubricant has a viscosity of from 30 to 80 centiStokes at 40° C.

10. The composition as claimed in claim 1 , wherein the lubricant is based on the at least one polyvinyl ether, and wherein the at least one polyvinyl ether is a copolymer of the following 2 units:

11. The composition as claimed in claim 1 , wherein the lubricant is based on the at least one polyvinyl ether.

12. A composition consisting of at least one lubricant comprising at least one polyvinyl ether and a refrigerant consisting of 3,3,3-trifluoropropene, wherein the at least one polyvinyl ether is a copolymer of the following 2 units:

13. The composition as claimed in claim 12 , wherein the at least one polyvinyl ether represents between 10% and 50% by weight of the composition.

14. The composition as claimed in claim 12 , wherein the at least one polyvinyl ether has 50% to 95% by weight of unit 1.
