The calculation of the compressibility, thermal expansion coefficient and the determination of the evaporation curve for some important refrigerants.

Author(s) : AVSEC J., MARCIC M.

Summary

The paper presents the mathematical model of computating the compressibility, thermal expansion coefficient, evaporation curve, velocity of sound and other thermophysical properties by means of statistical thermodynamics for some important refrigerants. The mathematical model enables the calculation in both sub- and supercritical region. By means of the mathematical model described, it was possible to compute thermodynamic properties in one and two-phase region and to draw phase diagrams for some technically significant substances. The results of the analysis are compared with data on experiments showing a relatively good agreement.
