Résumé

The composition is calculated by considering the composition distribution in the cycle and mass conservation of each component of the mixtures. The composition distribution in the gas-liquid two-phase region is calculated with an assumption of local equilibrium in each phase. The predicted compositions are also compared with experimental results which are obtained for R407C. The theoretical analysis shows that the composition distributions of the more volatile components, R32 circulating fractions of R32 and R125, are slightly larger than the charged fractions when appropriate amount of refrigerant is charged in the cycle. This difference increases with addition of more refrigerants, which results in the presence of liquid in the accumulator. The theoretical analysis shows good agreement with the experimental results.
