NUMERICAL ANALYSIS OF THE FROSTING PERFORMANCE OF THE AIR-SIDE OF A HEAT PUMP

摘要

This work is dealing the frosting model based on the analytical approximations of the heat and mass transferrnequations, which is validated on the generic reference case of frost creation over a flat horizontal surface.rnThis model has been implemented into a general purpose computational fluid dynamics (CFD) open sourcernplatform. Subsequently, this approach has been deployed in the parametric study of the heat exchanger finrngeometries, aiming at their design with respect to the frosting characteristics. The obtained results arerncompared to the experimental observations for the frosting performance of actual heat exchangers.
