Abstract

We report on the first demonstration of the four sequential steps in magnetocaloric regeneration of a magnetocaloric material: magnetization, warm blow, demagnetization, and cold blow. The experimental results display temperature divergence due to regeneration. Periodic temperature change of the solid bed is provided by the magnetocaloric effect in a periodic field change between 0 T and 2 T. The four sequential steps of each cycle are discussed. We present a theory of thermal wave propagation during the transient period of the refrigeration process in the regenerative bed combined with the magnetocaloric effect. A model for the temperature profile in an active magnetic refrigeration system is discussed.
