Pt. 1 How It Works: Solid State Heat Pumping with Magnets | E4C Seminar Series

Learn how experimental solid-state heat pumps made from magnetocaloric materials work. Dr. Radhika Barua of Virginia Commonwealth University presents breakthrough research in this Engineering for Change Seminar. Global demand for space cooling and water heating is growing, especially in regions already vulnerable to the impacts of climate change. There is an urgent need to move beyond traditional vapor-compression systems, however, because they rely on refrigerants with high global warming potential. One promising alternative is solid-state heat pumping enabled by magnetocaloric materials, which heat up or cool down when exposed to a changing magnetic field. These materials are central to magnetocaloric heat pump technologies, which offer higher energy efficiency and eliminate the need for harmful refrigerants.
