An analytical model for convective condensation heat transfer of ternary refrigerant mixtures

The main purpose of this study is to propose a modeling of the condensation heat transfer characteristics of ternary refrigerant mixtures and to compare the modeling results with our experimental data. This condensation heat transfer model accounts for the mass transfer in the vapor and liquid phases. In addition, it takes into account the interaction effect in mass transfer among the individual components. The calculation results showed that vapor-side mass transfer dominates in the high quality region, whereas liquid-side mass transfer dominates in the low quality region. Consequently, the modeling results showed that the condensation heat transfer coefficient is affected by the vapor-side mass transfer resistance at high mass quality, while it is affected by the liquid-side mass transfer resistance at low mass quality. The predicted condensation heat transfer coefficients of R407C show good agreement with experimental data.
