An introduction to magnetic refrigeration.

Author(s) : EGOLF P. W., KITANOVSKI A., VUARNOZI D., et al.

Summary

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