Presented is a model for the simulation of the interaction between the airflow and the AC-system. Demonstrated is 1) a successful coupling of flow solver (PowerFLOW 4.1) with the Modelica-based Dymola system tool and the AirConditioning Library; making use of the previously validated underhood-environment; and 2) the importance of a careful
design of the underhood flow for the AC-system performance. The validity of the developed simulation capability is tested by successful comparison with the available experimental data for the condenser at the given operating conditions. Shown is the potential for the analysis of the flow details and structures affecting the condenser performance like airflow recirculation.
