Summary

In order to prove the effectiveness of the model developed in the first report, about dynamics of a vapour compression refrigeration cycle with zeotropic refrigerant mixtures, simulation results are compared with the experimental results obtained for R407C. The simulation results are consistent with the experimental results. As a result of the numerical analysis of dynamic characteristics of composition changing, the variation of compositions in the refrigeration cycle is caused by the variation of the existing compositions of accumulator. The time constant of the composition is approximately equal to the time constant of the pressure and the mass distribution.
