7.1.6 Danish Prototypes

The rst magnetocaloric testing device from the Technical University of Denmark

(Table 7.7 ) was presented in 2008 by Bahl et al. [ 27 ]. The AMR was constructed of
0.9-mm-thick Gd plates with a spacing of 0.8 mm between two plates. The total
mass of the AMR was 92 g. A magnetic eld of up to 1.4 T was provided by an

electromagnet. In the initial experimental studies, a number of different in

fl uential

parameters were varied and tested, such as fluid displacement, cycle periods,
