Abstract

The present invention relates to refrigerant compositions containing trans-chloro-3,3,3-trifluoropropene (1233zd(E)) useful for chiller applications and processes using 1233zd(E).

First claim

We claim:

1. A method for producing refrigeration comprising compressing a refrigerant composition comprising trans1-chloro-3,3,3-trifluoropropene (1233zd(E)), wherein said compressing occurs within a multiple stage centrifugal chiller system.

2. The method of claim 1 wherein the compressing step comprises from about two to about five stages of compression.

3. The method of claim 1 wherein the refrigerant composition comprises at least 50 wt % 1233zd(E) based on total weight of the composition.

4. The method of claim 1 wherein the refrigerant composition comprises at least 70 wt % 1233zd(E) based on total weight of the composition.

5. The method of claim 1 wherein said refrigerant composition comprises a hydrofluoroolefin consisting essentially of 1233zd, wherein a majority of said 1233zd is 1233zd(E).

6. The method of claim 5 wherein said 1233zd(E) and 1233zd(Z) are in a ratio of about 2:1 to about 99:1.

7. The method of claim 6 wherein said ratio is about 4:1 to about 19:1.

8. The method of claim 1 wherein said refrigerant consists essentially of 1233zd(E).

9. The method of claim 1 wherein said chiller system comprises a heat transfer composition comprising said refrigerant and at least one lubricant.

10. The method of claim 9 wherein said heat transfer composition comprises form about 30 to about 50 percent by weight of said lubricant.

11. The method of claim 10 wherein said chiller system is included in a commercial air conditioning system.

12. The method of claim 10 wherein said chiller system has from about two to about five stages.

13. The method of claim 10 wherein said chiller system has from about two to about three stages.

14. The method of claim 9 wherein said lubricant is selected from polyol esters (POEs), poly alkylene glycols (PAGs), silicone oil, mineral oil, alkyl benzenes (ABs), poly(alpha-olefin) (PAO) and combinations of these.

15. The method of claim 9 wherein said lubricant comprises mineral oil.

16. The method of claim 9 wherein said refrigerant is a nonflammable.

17. The method of claim 9 wherein said chiller system is included in a commercial air conditioning system.

18. The method of claim 1 wherein said chiller system has from about two to about five stages.

19. The method of claim 1 wherein said chiller system has from about two to about three stages.

20. A centrifugal chiller system comprising:
a. a multistage centrifugal compressor; and
b. a refrigerant comprising trans1-chloro-3,3,3-trifluoropropene (1233zd(E)), wherein said refrigerant is disposed within said centrifugal compressor.

21. The centrifugal chiller system of claim 20 wherein the refrigerant composition comprises at least 50 wt % 1233zd(E) based on total weight of the composition.

22. The centrifugal chiller system of claim 20 wherein the refrigerant composition comprises at least 70 wt % 1233zd(E) based on total weight of the composition.

23. The centrifugal chiller system of claim 20 wherein said refrigerant composition further comprises 1233zd(Z).

24. The centrifugal chiller system of claim 23 wherein said 1233zd(E) and 1233zd(Z) are in a ratio of about 2:1 to about 99:1.

25. The centrifugal chiller system of claim 24 wherein said ratio is about 4:1 to about 19:1.

26. The centrifugal chiller system of claim 20 wherein said refrigerant consists essentially of 1233zd(E).

27. The centrifugal chiller system of claim 20 wherein said chiller system comprises a heat transfer composition comprising said refrigerant and at least one lubricant.

28. The centrifugal chiller system of claim 27 wherein said heat transfer composition comprises form about 30 to about 50 percent by weight of said lubricant.

29. The centrifugal chiller system of claim 27 wherein said lubricant is selected from polyol esters (POEs), poly alkylene gycols (PAGs), silicone oil, mineral oil, alkyl benzenes (ABs), poly(alpha-olefin) (PAO) and combinations of these.

30. The centrifugal chiller system of claim 27 wherein said lubricant comprises mineral oil.

31. A commercial air conditioning system comprising the centrifugal chiller system of claim 30 .

32. The centrifugal chiller system of claim 27 wherein said refrigerant is a nonflammable.

33. The centrifugal chiller system of claim 27 wherein said chiller system has from about two to about five stages.

34. The centrifugal chiller system of claim 27 wherein said chiller system has from about two to about three stages.

35. A commercial air conditioning system comprising the centrifugal chiller system of claim 20 .

36. The centrifugal chiller system of claim 20 wherein said chiller system has from about two to about five stages.

37. The centrifugal chiller system of claim 20 wherein said chiller system has from about two to about three stages.
