Abstract (en)

[origin: WO9719144A1] A refrigeration working fluid composition which is miscible or partially miscible at temperatures of less than 120 DEG C and which is immiscible at temperatures of at least about 120-180 DEG C, the refrigeration working fluid comprising: (i) about 65 to 95 weight % of a refrigerant, based on the total weight of the working fluid composition, the refrigerant comprising a blend of pentafluoroethane, 1,1,1-trifluoroethane, and 1,1,1,2-tetrafluorothane, wherein the tetrafluoroethane is present in an amount of between about 0.5 to 10 weight %, based on the total weight of the refrigerant, and (ii) about 5 to 35 weight % of a polyol ester lubricant, based on the total weight of the working fluid composition.
