A diesel engine global simulation tool - benefits in coolant loop optimization and additional heating systems use
Résumé
This article focuses on a global simulation software of a car cooling system. The sub-models involved are firstly detailed. A computation of air temperature blown into the car cabin is satisfactory compared to experimental results carried out in wind tunnel. In a second part, an example of an optimized defrosting strategy is described. Finally, the impact of several additional heating systems, burners and electrical systems, is studied in term of comfort and fuel consumption. The evaluation of the different technologies relies on a dimensionless indicator which links car cabin comfort and fuel consumption.
