Heat pumps without compressors: Fraunhofer advances electrocalorics

Highly efficient solid-state heat pumps without compressors – that is the vision of Fraunhofer researchers. With the recent completion of the ElKaWe research project, they took a big step towards realizing this vision. The team made great progress in terms of material and system design, and set up the first electrocaloric demonstrators to show the vast potential of this technology.
