Abstract

Disclosed are refrigerants, and heat transfer compositions, heat transfer systems and heat transfer methods containing such refrigerants, wherein the refrigerant comprises at least about 97% by weight of the following three components (a)-(c) and the following fourth component if present:
(a) trans-1-chloro-3,3,3-trifluoropropene (HFCO-1233zd(E)), (b) trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)), (c) trifluoroiodomethane (CF3I), and. (d) 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea).

First claim

The invention claimed is:

1. A refrigerant consisting essentially of at least about 97% by weight of the following four compounds, with each compound being present in the following relative percentages:
from 1% by weight to 2%+/−0.5% by weight trans-1-chloro-3,3,3-trifluoropropene (HFCO-1233zd(E)),
from about 73% by weight to about 87% by weight trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)),
4.4%+/−0.5% by weight 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea), and
from about 6.6% by weight to about 20.6% by weight trifluoroiodomethane (CF 3 I).

2. A heat transfer composition comprising a refrigerant of claim 1 .

3. The heat transfer composition of claim 2 further comprising a lubricant.

4. The heat transfer composition of claim 3 further comprising a stabilizer.

5. The heat transfer composition of claim 2 further comprising a stabilizer.

6. The refrigerant of claim 1 consisting essentially of at least about 97% by weight of the following four compounds, with each compound being present in the following relative percentages:
about 2% by weight trans-1-chloro-3,3,3-trifluoropropene (HFCO-1233zd(E)),
about 84% by weight trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)),
about 4.4% by weight 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea), and
about 9.6% by weight trifluoroiodomethane (CF 3 I).

7. A heat transfer composition comprising the refrigerant of claim 6 and a stabilizer.

8. A heat transfer composition comprising the refrigerant of claim 6 , a stabilizer and a lubricant.

9. A refrigerant consisting essentially of at least about 97% by weight of the following three compounds, with each compound being present in the following relative percentages of:
from 1% by weight to 3% by weight trans-1-chloro-3,3,3-trifluoropropene (HFCO-1233zd(E),
from about 77% by weight to about 83% by weight trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E), and
from about 15% by weight to about 21% by weight trifluoroiodomethane (CF3I).

10. A heat transfer composition comprising a refrigerant of claim 9 .

11. The heat transfer composition of claim 10 further comprising a lubricant.

12. The heat transfer composition of claim 11 further comprising a stabilizer.

13. The heat transfer composition of claim 10 further comprising a stabilizer.

14. A method of cooling in a heat transfer system comprising an evaporator, a condenser and a compressor, the method comprising the steps of
i) condensing a refrigerant consisting essentially of at least about 97% by weight of the following four compounds, with each compound being present in the following relative percentages:
a) from 1% by weight to 2%+/−0.5% by weight trans-1-chloro-3,3,3-trifluoropropene (HFCO-1233zd(E)),
b) from about 73% by weight to about 87% by weight trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)),
c) 4.4%+/−0.5% by weight 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea), and
d) from about 6.6% by weight to about 20.6% by weight trifluoroiodomethane (CF 3 I); and

ii) evaporating said refrigerant in the vicinity of a body, fluid or article to be cooled, wherein the evaporator temperature of the heat transfer system is in the range of from about −40° C. to about 10° C.

15. The method of claim 14 wherein the heat transfer system is an air conditioning system.

16. The method of claim 15 wherein said refrigerant is a replacement for R-134a in said heat transfer system.

17. The method of claim 15 wherein said refrigerant consisting essentially of at least about 97% by weight of the following four compounds, with each compound being present in the following relative percentages:
about 2% by weight trans-1-chloro-3,3,3-trifluoropropene (HFCO-1233zd(E)),
about 84% by weight trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)),
about 4.4% by weight 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea), and
about 9.6% by weight trifluoroiodomethane (CF 3 I), and wherein said refrigerant is non-flammable when tested in accordance with ASTM E681-2009 test procedure as required in ASHRAE Standard 34-2013 and described in Appendix B1 to ASHRAE Standard 34-2013.

18. The method of claim 14 wherein the air conditioning system is selected from a commercial air conditioning system, a mobile air conditioning system, a chiller, a residential air conditioning system, an industrial air conditioning system or a commercial air conditioning system.

19. The method of claim 18 wherein said refrigerant is a replacement for R-134a in said heat transfer system.

20. The method of claim 14 wherein said refrigerant is a replacement for R-134a in said heat transfer system.
