Development of a simulation model for pbkp_redicting dynamic behaviour of heat pump with nonazeotropic refrigerant mixtures

Abstract:

A lumped parameter model has been developed to pbkp_redict the dynamic behaviour of heat pumps with nonazeotropic 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 in heat pump operation. In addition, the proposed model includes the consequent effect of different refrigerant flow regimes and slip between two phases. Numerical results indicate that the present model pbkp_redicts fairly the heat pump dynamic response and that it compares well with experimental data. Copyright © 1992 John Wiley & Sons, Ltd.
