Dennis Pfeil, a former student, is returning to his alma mater: Since the beginning of the year, he has assumed the professorship for sustainable energy systems at the Department Mechanical and Energy Engineering in Giessen . His focus is on refrigeration and heat pump technology as a central component of the energy transition.

The heat pump is considered a key technology for climate -friendly heating. In Germany, it is the heating system of choice in the new building and for residential building renovations with 65 percent. With the professorship for sustainable energy systems, the THM reacts to the growing importance of cold and heat pump technology and expands its skills in this technology area.

Dennis Pfeil has deep roots in this field: His professional career began with an apprenticeship as a refrigeration engineer at Weiss Umwelttechnik in Reiskirchen. He then studied energy systems engineering at the former Giessen -Friedberg University of Applied Sciences (FH Giessen-Friedberg) – now the THM – and graduated with a degree in engineering in 2010. In addition to his training, Pfeil gained professional experience in the heating technology industry, including at Bosch Thermotechnik and later at Viessmann Climate Solutions, where he contributed to the development of modern heat pump systems.

His doctorate in the area of ​​cold and compressor technology gained arrow in 2021 with an examination of the long-term behavior of heat pumps and the hermetic refrigerant compressors used therein. He developed a procedure with which internal wear processes can be analyzed on the basis of externally measurable diagnostic parameters - an innovative approach to examining the lifespan of such systems.

Prof. Pfeil is a member of the Robert Paul Kling-Prize 2022 of the VDI district association Mittelhessen. This was awarded to him for his outstanding dissertation. With his knowledge from craftsmanship, industrial development experience and scientific depth, Prof. Dr.-Ing. Dennis Pfeil further develop training and research in the area of ​​sustainable energy systems at the THM .
