Abstract By means of the transient hot-wire method, the thermal conductivity of refrigerant R115 was measured over a wide region around the thermodynamic critical point. The enhancement of thermal conductivity was clearly observed at states close to the critical point. The thermal conductivity obtained for saturated liquid was compared to data by other authors with satisfactory agreement. For the thermal conductivity including the critical enhancement, equations are given according to the suggestion by J. V. Sengers. Comparison with measured data shows systematic deviations, with theoretical values being larger except for temperatures very close to the critical and densities above the critical.
