5. Refrigeration machines and systems

Machine models in the form of prototypes – rotating or reciprocating – are described in various publications, reports or books, with the following references as examples [3][4][5][12] . The interlocking of the various elements (magnetocalorics and permanent magnets or superconductors), circuits (soft magnets, heat transfer fluid) and motorization means that machines and systems can take on significantly different forms depending on the (cooling) power required and the type of application targeted, in particular to be able to operate in AMRR regenerative mode [3]...
