Summary

A thermodynamic model for the calculation of the enthalpy of a real working substance in the evaporator is proposed. Data on the phase equilibria of R134a/Castrol Icematic SW 22 and data on the heat capacity of Castrol Icematic SW 22 oil were used as initial information. The enthalpy of the liquid phase of the refrigerant-oil solutions was calculated. Based on the information obtained, logarithm p-h, diagrams for working substances with different oil concentrations, circulating over the contour of the refrigerating system, were developed.
