Abstract

The paper presents selected problems of numerical modelling of an advanced thermalFSI (Fluid solid interaction) approach of evaporator of air heat pump. The example of a fin-tube evaporator has been studied, focusing on obtaining the heat exchanger characteristics applying two-phase flow model for the in-tube refrigerant flow. Special attention is given to heat transfer between separated medium for different air velocity and changed refrigerant mass flow in-tube.
