Résumé

An investigation of a room temperature active magnetic refrigerator was carried out in this work. An experimental rig was built, in which two reciprocating regenerative beds packed with 1167.4 g of gadolinium were used, helium gas was used as a heat transfer fluid, and an average 1.5 T magnetic field was supplied by permanent magnets. With this apparatus, the influence of the gas pressure, the operating frequency and the temperature range were studied systematically. The lowest no heat load temperature of -2.79°C at the cold end heat exchanger and a maximum no heat load temperature span of 42.28°C were obtained. A maximum cooling power of 51.3 W was achieved over a temperature span of 18.16°C. The results in this study provide useful data for future design and development of room temperature magnetic refrigerators.
