Summary

Spanish translation of the IIR Informatory Note on Refrigerating Technologies (see the Bulletin of the IIR, reference 2008-0209). Magnetic refrigeration is an adiabatic cooling method which applies the magnetocaloric effect. From the point of view of basic physics, it shows an analogy to the conventional gas compression/expansion method. It has been applied for many years in cryogenics, to reach very low temperatures. In 1976, Brown presented the first room temperature refrigerator applying adiabatic magnetization and demagnetization. This note briefly highlights the state-of-the-art, the advantages and disadvantages of this promising technology.
