Getting warmer on solid-state heat pumps

Scientists at Germany’s Fraunhofer Institute for Applied Solid State Physics (IAF) have made a breakthrough in refrigerant-free heating and cooling technology: a circuit topology for voltage converters with an electrical efficiency of 99.74 per cent. According to the AIF, the technology could considerably raise the coefficient of performance for electrocaloric heat pumps and the scientists […]
