Hydrofluoroolefin compositions
The present invention relates to compositions containing hydrofluoroolefins and to the uses thereof as heat transfer fluids, blowing agents, solvents and aerosols. More particularly, the invention relates to compositions having: 10 to 90% by weight, of 2,3,3,3-tetrafluoropropene, 5 to 85% by weight of HFC-134a and 2 to 20% by weight of HFC-152a.
1. A composition comprising from 10 to 90% by weight of 2,3,3,3-tetrafluoropropene, from 5 to 85% by weight, of HFC-134a and from 2 to 20% by weight of HFC-152a.
2. The composition according to claim 1 , characterized in that it comprises from 2 to 15% by weight of HFC-152a, from 15 to 70% by weight of 2,3,3,3-tetrafluoropropene and from 15 to 70% by weight of HFC-134a.
3. The composition according to claim 1 , characterized in that it comprises 10 to 11% by weight of HFC-152a, 82 to 83% by weight of 2,3,3,3-tetrafluoropropene and from 6 to 7% by weight of HFC-134a.
4. The composition according to claim 1 , characterized in that it is (quasi)azeotropic.
5. A heat transfer fluid comprising from 10 to 90% by weight of 2,3,3,3-tetrafluoropropene, from 5 to 85% by weight, of HFC-134a and from 2 to 20% by weight of HFC-152a.
6. A blowing agent comprising from 10 to 90% by weight of 2,3,3,3-tetrafluoropropene, from 5 to 85% by weight, of HFC-134a and from 2 to 20% by weight of HFC-152a.
7. A solvent comprising from 10 to 90% by weight of 2,3,3,3-tetrafluoropropene, from 5 to 85% by weight, of HFC-134a and from 2 to 20% by weight of HFC-152a.
8. An aerosol comprising from 10 to 90% by weight of 2,3,3,3-tetrafluoropropene, from 5 to 85% by weight, of HFC-134a and from 2 to 20% by weight of HFC-152a.
