ABSTRACT:
There are disclosed refrigeration working fluid compositions comprising R125 (pentafluoroethane) or R152a (1,1-difluoroethane) refrigerants and certain polyol esters of C.sub.7 to C.sub.10 branched alkanoic acids or mixtures of such branched acids with linear C.sub.7 to C.sub.10 monoalkanoic acids. The polyols are neopentylglycol, technical grade pentaerythritol and trimethylolpropane; the esters exhibit suitable viscosity ranges and miscibility with refrigerants over a broad compositional range. The acids have a defined average effective carbon chain length in order to be miscible with the refrigerants over the range of 5 to 55 wt. % ester lubricant.
