- Abstract
The correlation dependence of thermal conductivity of liquid refrigerants on the saturation line is developed as a simple function of temperature : (where is the criterion unit, , and is the critical temperature). This dependence satisfies the requirements of dynamic scale theory (ST), and in particular, the passage to the limit . The proposed correlation dependence is tested using the example of describing the thermal conductivity of 17 liquid substances in the range of state parameters from the saturation line to the critical pressure and in the temperature range from the triple point temperature Ttr to . The substances reviewed include nine fourth-generation refrigerants of hydrofluorochloro derivatives of olefins, seven hydrochlorofluorocarbons and hydrofluorocarbons, and C3H8. Using the description of of C3H8 as an example, it is shown that the proposed correlation dependence not only qualitatively but also quantitatively accurately conveys the behavior of in the vicinity of the critical point. Based on the statistical analysis, it is shown that the proposed correlation with significantly less uncertainty describes the data on the thermal conductivity of liquid hydrofluorochloro derivatives of olefins both on the saturation line and in the single-phase region. Based on the proposed methodology, the thermal conductivity of the cis-isomer R1225ye(Z) is calculated for the first time in the temperature range .
