FIELD OF THE INVENTION The present invention relates to the use of chloro-trifluoropropene as a refrigerant in a negative-pressure liquid chiller and a method for replacing an existing refrigerant in the chiller with chloro-trifluoropropene. Chloro-trifluoropropenes, in particular 1-chloro-3,3,3-trifluoropropene, have high efficiency and unexpected high capacity in liquid chiller applications, and are substitutes for R-123 and R-11. It is useful as a more environmentally sustainable refrigerant for such applications, including. |
