K. Engelbrecht, Auteur ; K.K. Nielsen, Auteur ; N. Pryds, Auteur |Active magnetic regenerative (AMR) systems are being investigated because they represent a potentially attractive alternative to vapor compression technology. The performance of these systems is dependent on the heat transfer and pressure drop p[...]

K.K. Nielsen, Auteur ; C. R. H. Bahl, Auteur ; A. Smith, Auteur |A two-dimensional numerical heat transfer model is used to investigate an active magnetic regenerator (AMR) based on parallel plates of magnetocaloric material. A large range of parameter variations are performed to study the optimal AMR. The pa[...]

L. von Moos, Auteur ; K.K. Nielsen, Auteur ; K. Engelbrecht, Auteur |The magnetocaloric first order material MnFe(P,As) is a candidate for room temperature magnetic refrigeration. However, these materials have intrinsic hysteresis and the impact on the refrigeration performance has not yet been thoroughly investi[...]

K. Engelbrecht, Auteur ; C. R. H. Bahl, Auteur ; K.K. Nielsen, Auteur |Magnetic refrigeration is a potentially environmentally-friendly alternative to vapor compression technology because it has a potentially higher coefficient of performance and does not use a gaseous refrigerant. The active magnetic regenerator r[...]

K.K. Nielsen, Auteur ; Jaka Tušek, Auteur ; K. Engelbrecht, Auteur |The active magnetic regenerator (AMR) is an alternative refrigeration cycle with a potential gain of energy efficiency compared to conventional refrigeration techniques. The AMR poses a complex problem of heat transfer, fluid dynamics and magnet[...]

K.K. Nielsen, Auteur ; C. R. H. Bahl, Auteur ; A. Smith, Auteur |The performance of Active Magnetic Regenerators (AMR) does not depend solely on the magnetocaloric effect of their constituents. Rather, it depends on several additional parameters, including, magnetic field, geometry (hydraulic diameter, cross-[...]
