Resumo
In this paper we analyse the situation for the dielectric properties of the refrigerants, from the experimental and theoretical point 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 and correlation. The relation of Báron and Buep was analysed and extended to include the effects of pressure variation. Analogies between the Vedam equation and rough hard-sphere theory of transport properties were encountered and discussed.
