New Correlation of the Temperature-Dependent Thermal Conductivity of Binary Saturated Refrigerants Mixtures

In this paper, we utilize the REFPROP database and establish a new correlation between the temperature and the thermal conductivity of binary saturated refrigerants mixtures. Not only have we achieved a uniform set of parameters for each mixtures group at different ratios, but we have also considered the effect of the temperature T on the thermal conductivity \({{\lambda }_{m}}\) of the binary saturated refrigerants mixtures. The calculated results are compared with the data from the REFPROP database. The average absolute deviations (AADs) are computed. The majority of AADs are found to be less than 0.5% for all the cases considered. When compared to previously published correlations, this correlation better predicts the thermal conductivity of binary saturated refrigerants mixtures and will be useful for the future researches related to the heat dissipation engineering and engineering technology.
