Thermodynamic properties computation of two possible substitute refrigerants: R143a (1,1,1-trifluoroethane) and R125 (pentafluoroethane).

Author(s) : BARRET M., CANDAU Y.

Summary

Through application of four basic relations, the authors can calculate a number of thermodynamic properties for a given fluid. They applied these relations to CFC alternatives R143a and R125. Equation of state was implemented under the form of Martin-Hou equation, the coefficients of which were calculated from critical properties, normal boiling point temperature and molar mass. The state equation thus obtained is in good agreement with existing experimental data for R143a. The authors present thermodynamic tables for saturated vapour and liquid properties and also for superheated vapour. The authors give Mollier's diagrams.
