Abstract
Equations describing viscosity and thermal conductivity experimental data of refrigerants mixture R32/R134a are compiled. Equations represent the dependence of viscosity and thermal conductivity of this mixture from temperature, density and composition. They permit to calculate viscosity at temperature intervals 298…423 К at pressure up to 7,6 MPa at subcritical and 246…330 К up to 2,6 MPa at supercritical densities. Thermal conductivity is described at intervals 298…423 К up to 6,3 MPa at subcritical and 193…323 К up to 30 MPa at supercritical densities. Standard and maximum deviations of the experimental values from calculated are not exceed 3,0 and 5,0 % for viscosity and 2,5 and 4,9 % for thermal conductivity.
