Réfrigération magnétique : des principes fondamentaux aux applications

The paper introduces the working principle of magnetic cooling, it hinges from a paper oriented towards magnetocaloric materials [k733] and one oriented towards cooling system [BE 9 830]. Based on thermodynamic analysis, it makes a strong link between materials and systems. This paper aims to understand advantages and limitations of magnetic cooling devices studied today. After an introduction of the cooling context as well as its related energy consumption, magnetocaloric effect and magnetocaloric materials are described based on thermodynamic. Then, we explain how cooling is reached through thermodynamic cycle and how devices work.
