摘要: At present hydrofluorocarbons (HFCs) such as R32, R-125, R-134a, and R-143a are widely used, it is required to obtain accurate information of thermophysical properties, especially the thermal conductivity HFCs. In this paper new equations for R-32, R134a, R143a proposed, applicable over a wide range temperature pressure including critical region based on existing experimental data, reliability summarized. The problem that calculated from diffusivity in differs depending equation state also discussed.
