摘要
There are disclosed refrigeration working fluid compositions comprising 1,1,1-trifluoroethane refrigerant and either a neopentylglycol ester of 3,5,5-trimethylhexanoic acid or a trimethylolpropane ester of a mixture of 65 wt. % 3,5,5-trimethylhexanoic acid, 22.2 wt. % n-heptanoic acid and 12.8 wt. % methylhexanoic acid. The esters exhibit suitable viscosity ranges and miscibility with the refrigerant over a broad compositional range.
