Summary

A model for modelling the thermodynamic properties of ternary mixtures of R32, R125 and R134a was developed. It was shown that the refrigeration capacity of a ternary mixture of R32, R125 and R134a does not differ much from the initial value after several leakages followed by a consecutive filling up, and that the refrigeration capacity before the filling up decreased minimally to 90% of the initial value. After the filling up of the plant, the refrigeration capacity reaches minimally 95% of the initial capacity, and after five cycles leakage/filling up either the composition of the refrigerant and the refrigeration capacity remain constant.
