The device used the same magnet assembly and valve system as in their second
prototype [

]. Twelve AMR beds were arranged circumferentially. Each AMR bed
was
lled with six layers of different La

H magnetocaloric materials had six different Curie temperatures. These
were at 303.5, 306.2, 309.1, 311.6, 313.7 and 316 K, respectively. The heat-transfer
