The purpose of this paper is to extract information about intermolecular pair interaction potential energies of mixtures of ozone-friendly refrigerants by the usage of the inversion method and then to predict the dilute gas transport properties of this class of fluids. The components of studied mixtures are nine environmentally acceptable refrigerants consisting of R125, R134a, R152a, R143a, R32, R236ea, R236fa, R227ea, and RC318. Using the inverted pair potential energies, the Chapman-Enskog scheme is employed to calculate transport properties of the aforementioned systems excluding thermal conductivity. The calculation of thermal conductivity using inverted pair potential energies through Schreiber's scheme is discussed. In the temperature range 200 K < T < 1000 K, the accuracies of the calculated viscosities and the thermal conductivities amount to +/- 2% and at most +/- 15%, respectively.
