Abstract: This invention relates to the use of chloro-trifluoropropenes as refrigerants in negative-pressure liquid chillers and methods of replacing an existing refrigerant in a chiller with chloro-trifluoropropenes. The chloro-trifluoropropenes, particularly 1-chloro-3,3,3-trifluoropropene, have high efficiency and unexpectedly high capacity in liquid chiller applications and are useful as more environmentally sustainable refrigerants for such applications, including the replacement of R-123 and R-11.

Abstract: A polyol pre-mix containing at least one halogenated hydroolefin blowing agent and having improved shelf life stability is provided, wherein each polyol combined with the halogenated hydroolefin blowing agent has an apparent pH of between 3 and 11.4. Controlling the apparent pH of the polyol(s) enables the polyol pre-mix to be stored for extended periods of time and then used in combination with organic polyisocyanate to produce foam formulations having gel times and tack free times not significantly different from those exhibited when freshly prepared polyol pre-mix is used.
