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[...]

C. R. H. Bahl, Auteur ; K. Engelbrecht, Auteur ; R. Bjørk, Auteur |Design considerations for a prototype magnetic refrigeration device with a continuously rotating AMR are presented. Building the active magnetic regenerator (AMR) from stacks of elongated plates of the perovskite oxide material La0.67Ca0.33−xSrx[...]

R. Bjørk, Auteur ; A. Smith, Auteur ; C. R. H. Bahl, Auteur |An expression is determined for the mass of the magnet and magnetocaloric material needed for a magnetic refrigerator and these are determined using numerical modeling for both parallel plate and packed sphere bed regenerators as function of tem[...]

C. R. H. Bahl, Auteur ; K. Engelbrecht, Auteur ; D. Eriksen, Auteur |A novel rotary magnetic refrigeration device has been designed and constructed following the concepts recently outlined in Bahl et al. (2011). The magnet and flow system design allow for almost continuous usage of both the magnetic field and the[...]

J. A. Lozano, Auteur ; K. Engelbrecht, Auteur ; C. R. H. Bahl, Auteur |Experimental results for a recently developed prototype magnetic refrigeration device at the Technical University of Denmark (DTU) were obtained and compared with numerical simulation results. A continuously rotating active magnetic regenerator [...]

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[...]

U. L. Olsen, Auteur ; C. R. H. Bahl, Auteur ; K. Engelbrecht, Auteur |A high-performance magnetic refrigeration device is considered as a potential technology for in-vehicle air conditioners in electric vehicles. The high power consumption of a conventional air conditioner in an electric vehicle has considerable i[...]

R. Bjørk, Auteur ; C. R. H. Bahl, Auteur ; A. Smith, Auteur |One of the key issues in magnetic refrigeration is generating the magnetic field that the magnetocaloric material must be subjected to. The magnet constitutes a major part of the expense of a complete magnetic refrigeration system and a large ef[...]

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-[...]
