Improvement of the performance of room temperature magnetic refrigerator system.

Number: pap. P21

Author(s) : OKAMURA T., ITO K., HIRANO N.

Summary

The performance of a room-temperature magnetic refrigerator has been improved. The magnetic refrigeration does not use environmentally hazardous fluids. In order to improve the magnetic refrigerator, mainly the following components have been modified: 1) magnets; 2) AMR (active magnetic regenerator) ducts; 3) a pump; 4) piping. Coefficient of performance (cooling power at 5°C temperature span / power consumption of the system) of 2.5 was achieved after the modifications using gadolinium as a cooling source and 1.1 T permanent magnets.
