There is a possibility that the single magnetic refrigeration unit is connected in a
cascade arrangement with the second magnetic refrigeration unit (Fig. 8.5 ).
This would be similar to a conventional cascade refrigeration system (e.g.,
double, triple or multiple stage). However, if each of the magnetic refrigeration units
provides an AMR cycle, then we will show that the cascading does not make much
sense, unless the geometric or other restrictions demand this. Figure 8.5 shows an
example of the connection of two AMR-based magnetic refrigeration units. This is
