Summary

A lumped parameter model presented in the article, to predict the dynamic behaviour, is an extension of binary modelling of heat pumps with non-azeotropic refrigerant mixtures. The mathematical formulation of this model is based on mass, momentum, and energy balances. Several constitutive relationships are adopted in this model to describe the different phenomena encountered during heat pump operation with special emphasis on newly developed correlations to predict heat and mass transfer. In addition, the proposed model includes the consequent effect of different refrigerant flow regimes and slip between the two phases. Extensive simulations showed that the present model predicts fairly the heat pump dynamic response using ternary non-azeotropic refrigerant mixtures, and agrees well with experimental data under various geometries and conditions.
