Analysis of room temperature magnetic regenerative refrigeration

Detailed numerical modeling of a linear parallel-plate Active Magnetic Regenerator

“…Dikeos et al, 2006;Li et al, 2006;Engelbrecht et al, 2005;Shir et al, 2005;Allab et al, 2005) with the exception of one, published in Petersen et al (2008), which is a two-dimensional model of a parallel-plate design. In the one-dimensional models the regenerator is discretized with a sufficient number of grid cells in the x-direction (parallel to the flow) and thus a lumped analysis needs to be employed in order to describe the heat transfer between the active MCM and the heat transfer fluid.…”

Tailoring of magnetocaloric response in nanostructured materials: Role of anisotropy

“…1-5͒. Although the magnetocaloric effect ͑MCE͒ is not new ͑it was discovered by Warburg 6 in 1881͒, the combination of the recent discovery of the giant magnetocaloric effect 7 and the perspectives of the application of MCE in room temperature magnetic refrigerators [8][9][10] accelerated the research efforts in this field. This refrigeration method, although not yet available in commercial appliances, offers numerous advantages over the conventional systems based on the compression expansion of gases, ranging from increased energetic efficiency to environmental benefits due to the avoidance of ozone depleting or green house related gases.…”

Experimental investigation of a three-material layered active magnetic regenerator

“…High frequency cycles may increase cooling power for a fixed magnetic field. A good list of much of the relevant work to do with active magnetic refrigeration can be found in the references of Shir et al [3].…”
