From Concept to ModelCore components of the heat pump system to be modeled• Refrigerant compressor mechanically driven with and without displacement orelectrically driven• Brazed plate heat exchanger. One used as an evaporator and one as a condenser• Expansion valve thermostatic and electrically drivenFurther components• Water pumps• Heat exchangers such as Radiator and Heater core• Auxiliary heatersBoundary conditions• Airflow through the heater core heat• Ambient temperature• Driving cycle waste heat from power train© IAV · 10/2012 · oka · VI-E22 7
