Researchers at the Fraunhofer Institute for Applied Solid State Physics (IAF) in Germany are making significant progress in the development of electrocaloric heat pumps that offer a promising alternative to compressor technology, with the goal of increasing efficiency and offering a more eco-friendly alternative to refrigerants.
This type of heat pump utilises the unique properties of electrocaloric materials, which have change their polarisation or the alignment of their positive and negative charges when an electric field is applied, leading to a temperature increase.
To maintain a stable temperature, the resulting heat is then dissipated through a heat sink, causing the material to cool down and return to its initial temperature.
