There are disclosed refrigeration working fluid compositions comprising tetrafluoroethane refrigerants and certain polyol esters of C7-C10 branched alkanoic acids or mixtures of such branched acids with linear C7-C10 monoalkanoic acids. The polyols are mono-, di- or technical grade pentaerythritol o...
