TL;DR: In this article, the authors discuss some of the main challenges encountered in the literature and how design choices impact cooling power and work requirements from a system engineering perspective, and propose an extended design/optimization methodology based on entropy generation minimization with performance criteria.
Abstract: Active magnetic regeneration is one of the most promising alternative technologies for the development of heat pumps and cooling systems for applications around room temperature. In the open literature, numerous works can be found in which much effort has been put on the development of magnetocaloric materials, magnetic circuits and prototypes. In this article, the authors discuss some of the main challenges encountered in the literature and how design choices impact cooling power and work requirements from a system engineering perspective. First, based on a generic schematic representation of a magnetocaloric heat pump, or refrigerator, various problems and challenges found in the current state of the art are pointed out and discussed. Second, different design principles for magnetic heat pumps are examined. As a means to improving performance, an extended design/optimization methodology is proposed based on entropy generation minimization with performance criteria. Finally, some initial optimization res...

TL;DR: In this paper, the authors present a historical and up-to-date account of the energy-related applications of magnetocaloric materials and information about their processing and magnetic fields, thermodynamics, heat transfer, and other relevant characteristics.
Abstract: The need for energy-efficient and environmentally friendly refrigeration, heat pumping, air conditioning, and thermal energy harvesting systems is currently more urgent than ever. Magnetocaloric energy conversion is among the best available alternatives for achieving these technological goals and has been the subject of substantial basic and applied research over the last two decades. The subject is strongly interdisciplinary, requiring proper understanding and efficient integration of knowledge in different specialized fields. This review article presents a historical and up-to-date account of the energy-related applications of magnetocaloric materials and information about their processing and magnetic fields, thermodynamics, heat transfer, and other relevant characteristics. The article also discusses the conceptual design of magnetocaloric refrigeration and power generation systems and some guidelines for future research in the field.
