Freiburg-based start-up Qurie GmbH, a spin-off from the Fraunhofer Institute for Physical Measurement Techniques IPM, is developing a solid-state heat pump that operates without conventional compressors or refrigerants. Unlike today's vapor-compression systems, which rely on refrigerant cycles and mechanical compressors, Qurie's technology uses the temperature change of electrocaloric materials under an applied electric field to drive a thermal cycle. According to the company, this approach could achieve significantly higher theoretical efficiencies of over 70%, compared to around 50% for conventional ...Den vollständigen Artikel lesen ...
