More Information
Summary: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. L'invention se rapporte à des compositions de fluide de réfrigération contenant le réfrigérant 1,1,1-trifluoroéthane et soit un ester de néopentylglycol d'acide 3,5,5-triméthylhexanoïque soit un ester de triméthylolpropane d'un mélange de 65 % en poids d'acide 3,5,5-triméthylhexanoïque, de 22,2 % en poids d'acide n-heptanoïque et de 12,8 % en poids d'acide méthylhexanoïque. Les esters présentent des plages de viscosités appropriées et une miscibilité avec le réfrigérant étendue sur une large gamme de compositions.
