In this paper, the refrigerant R11, R12, R13, R22, R23, R32, R13B1, R113, R114, R123, R124, R125, R134a, R141b, R142b, R143a, R152a, R227ea, R236ea, R236fa, R245ca, R245fa, R1234yf, R1234ze and the viscosity data of binary and ternary mixtures, a prediction model that can calculate the viscosity of the refrigerant and its mixture is established based on the free volume theory and the mixing rule. For the pure refrigerant viscosity, the absolute value of the relative deviation between the model predictive value and the experimental value is less than 1.5% and the absolute value of the maximum relative deviation is less than 3.1%. For the viscosity of binary and ternary mixtures of refrigerants, the absolute value of the relative deviation between the model predicted value and the experimental value is less than 3.6% and the absolute value of the maximum relative deviation is less than 7.5%.
