Air cooling system CALORIVAC®

From hot to cold and vice versa with improved efficiency HANAU – VACUUMSCHMELZE GmbH & Co. KG (VAC) is developing of environmental friendly materials for magnetocaloric cooling. The collaboration with the Fraunhofer IPM Institute and other partners started back in 2017 in the MagMed project with the aim of bringing sustainable and energy-efficient cooling to series production. The Fraunhofer IPM Institute has now achieved a breakthrough in terms of increasing the performance of magnetocaloric cooling systems. Magnetocaloric cooling systems do not require environmentally harmful or explosive refrigerants such as CFCs (chlorofluorocarbons) or butane. They are energy efficient and quiet, making them the first choice when it comes to replacing conventional compressor technology in the future. In laboratory experiments, it has now been possible to demonstrate a power density of 12.5 W per gram of material used. This is a previously unattained value. The supply of the magnetocaloric material in the form of microchannel regenerators (MCR), which VAC is developing towards series production readiness, plays an essential role in this. Contrary to previous manufacturing processes, the MCRs are produced using a foil casting process. This allows cost-effective, reliable production on an industrial scale. The different alloy variants of CALORIVAC® enable application over a wide temperature range.
