Dielectric properties of liquid refrigerants: facts and trends.

Author(s) : RIBEIRO A. P. C., NIETO DE CASTRO C. A.

Summary

In this paper, the authors analyse the situation for the dielectric properties of the refrigerants, both in the liquid and gaseous states, from the experimental and theoretical points of view, based on more than one decade of research of our group. Examples of the predictive power of simple models will illustrate the existing tools for electrical permittivity and dipole moment prediction correlation and correlation. The relation of Báron and Buep between the electrical permittivity and viscosity was analysed and extended to include the effects of pressure. Analogies between the Vedam equation and the rough hard sphere theory of transport properties were encountered and will be the object of future analysis.
