Group "Thermal Energy Systems"

AG TeS

The working group aims to design, understand, control and optimize cyber-physical complex thermal energy systems in order to integrate them into alternative vehicle concepts as well as into the "city of the future."

Working group leaders:

Tegethoff

Dr.-Ing. Wilhelm Tegethoff
Modeling, simulation, and optimization of cyber-physical complex thermal energy systems.

Lemke

Dr.-Ing. Nicholas Lemke
Experimental and theoretical investigation of energy-efficient thermal systems and components

Fields of Research

The working group researches on battery-electric cars, fuel cell trucks, hydrogen storage and refueling systems, dryers, wastewater treatment plants, heat pumps, refrigeration systems and air conditioning systems. In this context, components such as batteries, fuel cells, compressors, heat exchangers, mass transfer devices, thermo-electric modules and ejectors are analyzed. Novel control techniques are emerging. The natural refrigerant R744 is the focus of much research. Modern system and CFD simulation methods as well as novel measurement techniques are used. The working group cooperates nationally and internationally with numerous research institutions and companies.
