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).

Claims (13)

1. A method for producing refrigeration comprising compressing a refrigerant composition comprising 1233zd, wherein said compressing occurs within a centrifugal chiller system.

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

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

4. The method of claim 1 wherein said 1233zd comprises 1233zd(E).

5. A method for producing refrigeration comprising compressing a refrigerant comprising at least 50 wt % of 1233zd(E) in a chiller and thereafter evaporating the refrigerant in the vicinity of a body to be cooled.

6. The method of claim 5 wherein said refrigerant consists essentially of 1233zd(E).

7. A centrifugal chiller system comprising:

a. a centrifugal compressor; and

b. a refrigerant comprising 1233zd, wherein said refrigerant is disposed within said centrifugal compressor.

8. The centrifugal chiller system of claim 7 wherein the refrigerant composition comprises at least 50 wt % 1233zd(E) based on total weight of the composition.

9. The centrifugal chiller system of claim 7 wherein the refrigerant composition comprises at least 70 wt % 1233zd(E) based on total weight of the composition.

10. The centrifugal chiller system of claim 7 wherein said 1233zd comprises 1233zd(E).

11. The centrifugal chiller system of claim 7 wherein said refrigerant consists essentially of 1233zd(E).
