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[...]

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[...]

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[...]
