摘要

In this paper a novel Rotary Permanent Magnet Magnetic Refrigerator (RPMMR) is described. The principle ofrnoperation of the presented magnetic refrigerator is based on the AMR thermodynamic cycle. Gadolinium is selected as magnetic refrigerant and demineralized water is employed as heat transfer fluid. A 1.20 kg of gadolinium consisting of 400-500 μm spheres is housed in 8 regenerators. A magnetic system, based on a double U configuration of permanent magnets, provides a magnetic flux density of 1.25 T with an air gap of 43 mm, while a rotary vane pump forces the fluid through the regenerators. The operational principle and initial experimental results are shown.
