Experimental study of thermal conductivity of the $\mathrm{R}$-$407\mathrm{C}$ refrigerant in the vapor phase

Thermal conductivity of the gaseous $\mathrm{R}$-$407\mathrm{C}$ refrigerant was investigated by the coaxial cylinders method within the temperature range of $303$–$425$ K and the pressure range of $0.7$–$2.1$ MPa. Approximating dependence of thermal conductivity on pressure and temperature was obtained. Thermal conductivity on dew line and in ideal gas state was calculated. The comparison is performed of the data obtained with those available in the literature.
