| Abstract: | An investigation of an active magnetic refrigerator has been carried out for room temperature refrigeration with an average 1.5 T magnetic field supplied by permanent magnets. Helium gas was used as a heat transfer fluid. Using this prototype, a preliminary maximal temperature span of 10.7 K was achieved by adjusting the pressure of helium and the operation frequency. The results provide useful data for future magnetic refrigerator design, and provide a helpful reference for future development of room temperature active magnetic refrigerator. |
