Fraunhofer starts development of refrigerant-free, energy-efficient electrocaloric heat pumps

Heat pumps play a decisive role in the energy transition: Sustainably generated electricity provides heat in winter and a good climate in summer. Nowadays, heat pumps work almost exclusively on the basis of compressor technology. Compressors require harmful refrigerants, the use of which will be restricted even more by law in the future. In the Fraunhofer ElKaWe lighthouse project, six Fraunhofer Institutes are developing highly efficient electrocaloric heat pumps, which do without harmful refrigerants.

Federal Highway Research Institute BASt uses road surface scanner from Fraunhofer IPM for new assessment tool

The Pavement Profile Scanner PPS-Plus from Fraunhofer IPM is part of the latest measuring vehicle MESAS of the Federal Highway Research Institute BASt. The research vehicle records the condition of road surfaces and the substance of the asphalt surface and thus provides the basis for optimum maintenance planning. During test runs, MESAS has already successfully measured more than 11,000 kilometers of the federal trunk road network. Now regular operation starts.

A cooling system without harmful refrigerants

A discovery from 1917 becomes viable for the future. A team of researchers at the Fraunhofer Institute for Physical Measurement Techniques IPM is developing efficient magnetocaloric cooling systems that make do without harmful refrigerants. The esearchers hope to achieve 50 percent of the maximum efficiency level with their process. Comparable existing magnetocaloric systems reach only approximately 30 percent.

Planning infrastructure faster thanks to machine learning

Secure, stable and fast data transmission requires an area-wide network of fiber optic cables. But where is the best place to put the cable ducts? Finding the optimal cable route is enormously complex and time-consuming. A Team led by Prof. Dr. Alexander Reiterer, Dominik Störk and Dr. Katharina Wäschle from the Fraunhofer Institute for Physical Measurement Techniques IPM has developed a novel process chain based on machine learning that solves this issue. For this, the three mentioned scientists are awarded the Joseph von Fraunhofer Prize.
