Influence of thermal conductivity on the dynamic response of magnetocaloric materials
We compare the magnetocaloric effect of samples prepared with different thermal conductivities
to investigate the potential of composite materials. By applying the magnetic
field under operating conditions we test the material’s response and compare this to heat
transfer simulations in order to check the reliability of the adiabatic temperature change
probe used. As a result of this study we highlight how the material’s thermal conductivity
influences Ď„ , the time constant of temperature change. This parameter ultimately limits
the maximum frequency of a refrigerant cycle and offers fundamental information about
the correlation between thermal conductivity and the magnetocaloric effect
