Summary

The performance of an active magnetic regenerator refrigerator cycle depends strongly on the behaviour of the adiabatic magnetization temperature change as a function of material temperature in the flow direction of the regenerator. The refrigeration capacities and the thermal efficiencies of this family of regenerators were evaluated through a numerical simulation of a complete thermodynamic active magnetic regenerator cycle. The gadolinium-dysprosium alloys have been chosen as constituent materials for the regenerators operating over the temperature range 300 to 200 K.
