Abstract
Official abstract text for this publication.
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
Opening claim text (preview).
We claim: 1 . A method for producing refrigeration comprising compressing a refrigerant composition comprising 1233zd(E), wherein said compressing occurs within a centrifugal chiller system. 2 . The method of claim 1 wherein said compressing is performed in multiple stages. 3 . The method of claim 2 wherein the compressing step comprises from about two to about five stages of compression. 4 . The method of claim 1 wherein the COP is between 4.7 and 4.96. 5 . The method of claim 1 wherein the refrigerant composition comprises at least 50 wt % 1233zd(E) based on total weight of the composition. 6 . The method of claim 1 wherein the refrigerant composition comprises at least 70 wt % 1233zd(E) based on total weight of the composition. 7 . 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). 8 . The method of claim 7 wherein said 1233zd consists of 1233zd(E) and 1233zd(Z) in a ratio of about 2:1 to about 99:1. 9 . The method of claim 8 wherein said ratio is about 4:1 to about 19:1. 10 . 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. 11 . The method of claim 10 wherein said refrigerant consists essentially of 1233zd(E). 12 . A centrifugal chiller system comprising: a. a centrifugal compressor; and b. a refrigerant comprising 1233zd(E), wherein said refrigerant is disposed within said centrifugal compressor. 13 . The centrifugal chiller system of claim 12 wherein said centrifugal compressor comprises multiple compression stages. 14 . The centrifugal chiller system of claim 12 wherein the refrigerant composition comprises at least 50 wt % 1233zd(E) based on total weight of the composition. 15 . The centrifugal chiller system of claim 12 wherein the refrigerant composition comprises at least 70 wt % 1233zd(E) based on total weight of the composition. 16 . The centrifugal chiller system of claim 12 wherein said refrigerant composition comprises a hydrofluoroolefin consisting essentially of 1233zd, wherein a majority of said 1233zd is 1233zd(E). 17 . The centrifugal chiller system of claim 16 wherein said 1233zd consists of 1233zd(E) and 1233zd(Z) in a ratio of about 2:1 to about 99:1. 18 . The centrifugal chiller system of claim 17 wherein said ratio is about 4:1 to about 19:1. 19 . The centrifugal chiller system of claim 12 wherein said refrigerant consists essentially of 1233zd(E).
