The analysis of two-phase condensation heat transfer models based on the comparison of the boundary condition

Abstract

The article aims to present, analyze and select two-phase condensation heat transfer coefficients for the refrigerant-side in the condenser of the heating and cooling system of a heat pump. The heat transfer models are analyzed for condensation in horizontal smooth tubes. The mathematical models published by various authors refer to the range of heterogeneous condensation. The final aim of the analysis is to select the optimal model from the examined two-phase condensation heat transfer models. The selection of the condensing refrigerant two-phase heat transfer model is based on the boundary condition. The applied method of analysis is numerical-graphical.
