BLENDED POLYOL ESTER LUBRICANTS FOR REFRIGERANT HEAT TRANSFER FLUIDS

摘要

An ester blend, including an ester having neopentylglycol and a source of 2-ethylhexanoic acid as its reactive components and an esterhaving pentaerythritol and a source of 2-ethylhexanoic acid as its reactivecomponents, is especially effective as a lubricant for chlorine-freefluorocarbon refrigerant heat transfer fluids, particularly Refrigerant 134a(1,1,1,2-tetrafluoroethane).
