  • Performance improvement of magnetocaloric cascades through optimized material arrangement
    Patent number: 9915447
    Abstract: A magnetocaloric cascade containing at least three different magnetocaloric materials with different Curie temperatures, which are arranged in succession by descending Curie temperature, wherein none of the different magnetocaloric materials with different Curie temperatures has a higher layer performance Lp than the magnetocaloric material with the highest Curie temperature and wherein at least one of the different magnetocaloric materials with different Curie temperatures has as lower layer performance Lp than the magnetocaloric material with the highest Curie temperature wherein Lp of a particular magnetocaloric material being calculated according to formula (I): Lp=m*dTad,max with dTad,max: maximum adiabatic temperature change which the particular magnetocaloric material undergoes when it is magnetized from a low magnetic field to high magnetic field during magnetocaloric cycling, m: mass of the particular magnetocaloric material contained in the magnetocaloric cascade.
