ABSTRACT:
Refrigeration fluid compositions for compression refrigeration which have an upper solution critical temperature equal to or greater than about 35.degree. C. are composed of selected hydrochlorofluorocarbons and hydrofluorocarbons with esterified polyether polyols in which at least 30% of the hydroxyls are esterified. The esterified polyether polyols have a viscosity between 25 and 150 centistokes at 38.degree. C.
