Abstract

A prototype magnetic refrigerator has been developed, which consists of fixed active magnetic regenerator (AMR) beds and Halbach arrayed NdFeB magnets with a peak field of 1.5 Tesla rotating over the beds. Each bed was packed with sphere Gd or Gd-Y/Gd-Dy compounds. The total amount of magnetcaloric materials are 7.2 kg. The number of rotations is up to 40 min-1 and the volumetric flow rates are up to 25 L/min. The system has a maximum cooling capacity of 1.4 kW at the temperature span of zero, and a maximum temperature span of 21 K with Gd and Gd-Dy compounds.
