REFRIGERATION WORKING FLUID COMPOSITIONS
There are disclosed refrigeration working fluid compositions comprising tetraflu oroethane refrigerants and certain polyol esters of C7-C10 branched alkanoic acids or mixtures of such branched acids with linear C7-C10 moroalkanoic acids. The polyols are mono-, di- or technical grade pentaerythritol...

Summary: | There are disclosed refrigeration working fluid compositions comprising tetraflu oroethane refrigerants and certain polyol esters of C7-C10 branched alkanoic acids or mixtures of such branched acids with linear C7-C10 moroalkanoic acids. The polyols are mono-, di- or technical grade pentaerythritol or trimethylolpropane; the esters exhibit suitable viscosity ranges and miscibility with refrigerants over a broad compositional range. The acids ha ve a defined average effective carbon chain length and a certain degree of methyl branching for polyols other than trimethyl olpropane. |
