Description of equilibrium properties of R32 on the basis of scale hypothesis
On the basis of phenomenological theory of thecritical point and Benedek’s hypotheses justified the structure of the unified equation of state satisfying the scale theory of critical phenomena. Under the proposed approach, developed a unified equation of state of the refrigerant R32 in the temperature range from 136 K to 420 K. It is shown that in the framework of the proposed approach describes not only the regular part of the thermodynamic surface and the neighborhood of the critical point and region of metastable states. The results of the calculation of surface heat and isohoric heat capacity of the refrigerant R32.
