TL;DR: In this article, a rotary magnetic refrigerator was designed and built at the Federal University of Santa Catarina (UFSC) in Brazil, where two low-friction rotary valves were developed to synchronize the hydraulic and magnetic cycles.

TL;DR: In this paper, the authors presented a systematic experimental evaluation of three different regenerator geometries: parallel-plate, pin array and packed bed of spheres, and the results of cooling capacity, temperature span between the thermal reservoirs, coefficient of performance and second-law efficiency were generated as a function of utilization for different operating frequencies.

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.

TL;DR: In this paper, the authors describe the design, operation and preliminary results of an active magnetic regenerator test machine, which consists of twenty eight 085mm thick parallel gadolinium (Gd) plates that form 1.1mm-thick parallel channels with an effective length of 126mm.

TL;DR: In this paper, a new active magnetic regenerator (AMR) laboratory apparatus is presented and evaluated, which is composed of a nested Halbach cylinder magnetic circuit assembled in phase with a double effect displacer that provides the cold and hot blows to the regenerator.
