NEW MAGNETIC REFRIGERATION PROTOTYPE WITH APPLICATION IN HOUSEHOLD AND PROFESSIONAL REFRIGERATORS

摘要

The number of magnetic refrigeration prototypes with high cooling capacity and large temperature span is limited and there is ample room for new designs and improvements. In this paper a new prototype, designed and built, aiming at 200 W cooling capacity and about 40 K temperature span is presented. Such a unit is suitable for applications in household and professional refrigerators. In the current work, design of the prototype is described, practical issues solved to make the prototype running are explained, and preliminary test results are presented.
