“…The blow fraction was varied using different face seals in a rotary valve system that diverted different amounts of fluid from the regenerator, and fluid flow was provided from a gear pump. The magnetic profile was similar to that of Teyber et al (2017). The cooling capacity was observed to increase with a reduction in the blow fraction (for a fixed utilization).…”

“…However, experience with prototyping reveals that such a system can only provide good control of the pressure inside the hydraulic circuit at low operation frequencies. Bidirectional fluid propulsion, in the hydraulic circuit of magnetic refrigeration or heat pumping, is implemented with the use of check valves or cam valves . A static active magnetic regenerator also enables the use of a unidirectional pump.…”

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.

“…The AMR characterization involves both the magnetocaloric and heat transfer properties of the regenerator, which are generally characterized based by the temperature span, cooling capacity and efficiency of the AMR system [21]. Other AMR studies have focused on flow profiles [22][23][24][25] and working conditions [26,27]. Potential regenerator geometries can be tested with an applied magnetic field as an active regenerator or with no applied magnetic field as a passive regenerator and various test devices of each type have been presented in the literature [28,29].…”
