Latest Patents

Ward's latest patents include innovative formulations for refrigeration fluid compositions. One of his key inventions is the esterified polyglycol lubricants for refrigeration compressors. This invention focuses on refrigeration fluid compositions that have an upper solution critical temperature equal to or greater than about 35°C. These compositions are made from selected hydrochlorofluorocarbons and hydrofluorocarbons combined with esterified polyether polyols, where at least 30% of the hydroxyls are esterified. The esterified polyether polyols are designed to have a viscosity between 25 and 150 centistokes at 38°C. Another significant patent involves lubricant base compositions for compression refrigeration, which consist of 95 to 5% by weight of polyether polyols with a number average molecular weight ranging from about 400 to about 5000, and 5 to 95% of esters derived from polyhydric alcohols with alkanoic acids or alkanedioic acids with alkanols. This base composition is further enhanced by the addition of selected hydrochlorofluorocarbons and hydrofluorocarbons, ensuring miscibility with refrigerants in a temperature range from -20°C to greater than 65°C.
