Karlsruhe University of Applied Sciences Achieves Major Milestones in Refrigeration Research

THE SCHAUFLER FOUNDATION (TSF) is celebrating the fifth anniversary of its endowed professorship in compressor technology at the Institute for Refrigeration, Air Conditioning and Environmental Technology at Karlsruhe University of Applied Sciences. Introduced in 2019, the program has significantly advanced both teaching and research in the field.

"Strengthening research and teaching in air conditioning and refrigeration technology has been absolutely successful," said Ingo Smit, CEO of TSF. "The exciting projects and enthusiasm here at the university align perfectly with our goal of promoting refrigeration technology globally."

Prof. Dr. Robin Langebach, who holds the endowed chair, echoed these sentiments: "We've made significant steps in strengthening research and teaching, despite challenges like the lack of young talent, budget cuts, and COVID-19." His contributions include leading over 43 lectures and publications, serving on the DKV board, and representing Germany at the International Institute of Refrigeration (IIR) conference.

Dr. Heinz Jürgensen, Director of Application Technology and Special Projects at BITZER, praised the program's impact: "It is fascinating to see the potential that can still be tapped when optimizing compressor technology, especially in the area of energy efficiency. The enthusiasm among students and staff is a significant achievement."

Over the past decade, the number of first-year students in mechanical engineering and process engineering has nearly halved, according to Destatis. The success of initiatives like Karlsruhe's InspirING program - which introduces schoolchildren to refrigeration and air conditioning through engaging, practical examples - demonstrates the university's commitment to attracting young talent to these critical fields.

The department’s accomplishments include the popular "International Refrigeration and Compressor Course" summer school and the new Green Technology Management bachelor's program. These initiatives offer students in-depth insights into refrigeration and heat pump technology. The number of students pursuing bachelor’s theses and further studies in the department is growing, with five scientific and academic employees already on board.

One such employee, Jonas Schmitt, transitioned from automotive engineering to refrigeration technology after being captivated by the field during his studies. Currently pursuing a doctorate in liquid injection in reciprocating compressors, Schmitt noted that "injecting liquid refrigerant into the compressor allows for temperature control and can lead to energy savings of up to 10 percent with ammonia (R717)."

The TSF’s endowed professorship continues to drive innovation and excellence in refrigeration and air conditioning technologies, establishing a fruitful collaboration between industry and academia.
