Abstract

In this paper an energetic cabin model in Dymola is created to compare different heating strategies of a luggage tug. The cabin model is validated using a mock up in the climate chamber of the Institute of Vehicle Concepts at the German Aerospace Center. A virtual 20 kW fuel cell luggage tug has been created using Alternative Vehicles Library in Dymola. Heating concepts based on fuel cell thermal waste heat and conventional PTC heating strategies and compared using the virtual luggage tug model. The combination of waste heat and electric heating strategy led to the integration of a 60 liter enthalpy storage in the primary fuel cell cooling system. As a result, electric energy usage for heating is reduced by 60% while cabin temperature could be increased at 5 K up to 20 °C at -10 °C environmental conditions.
