Active magnetic regeneration is one of the most promising alternative technologies for the development of heat pumps and cooling systems for applications near room temperature. Recently, numerous papers have reported on the development of magnetocaloric materials, magnetic circuits, prototypes and cycle optimization. This presentation examines some of the main challenges encountered in the current state of the art technology. It provides an overview of how design choices impact cooling power and work requirements from a system engineering perspective.
