Technische Universität München; Lehrstuhl für Thermodynamik

The high efficiency of hybrid and electric drives means that the waste heat generated is not sufficient to heat the interior. In addition, the battery and electronics place demanding requirements on the vehicle's thermal management. The aim of the chair is to research exergy-optimized solutions - i.e. solutions that place as little load as possible on the vehicle's electrical storage system. Similar to the passive house, the thermal power required is to be reduced as far as possible. Approaches such as insulating glazing, heat recovery, air recirculation or alternative heating systems (e.g. seat or floor heating) are being researched. In particular, the use of a heat pump is being researched to cover heating and cooling requirements. This poses new challenges in terms of the optimum connection and operating strategy. In winter operation in particular, solutions to prevent the front-end evaporator from icing up are being researched.
