Résumé

At present, a great amount of research work is performed to develop new magnetocaloric materials, which are the refrigerants of magnetic refrigerators. This leads to a continuous development of more performant magnetic refrigerants with higher entropy differences, higher adiabatic temperature differences and lower hysteresis effects. Also, an increased activity to design better thermomagnetic refrigerators is occurring and numerous promising patents on machines with magnetocaloric porous beds have been deposited. In a new IIR Working Party on Magnetic Refrigeration, the different activity groups enter into close relation, leading to welcome interactions between material scientists, physicists working on magnetism and specialists on fluid dynamics and thermodynamic machine design. All these increasing activities lead to a very high potential of magnetic refrigerators for a market penetration, which most probably at first will occur in some niche markets. After that for some main sales domains of refrigeration - e.g. as for usual commercial refrigerators - an entrance to the market also seems feasible. Other markets are in air conditioning, heat pump applications, process techniques, automobile industry, medical domains, etc.
