Summary

This paper describes the design, operation and preliminary results of an active magnetic regenerator test machine. The regenerator consists of 28 parallel Gd plates (126 mm long, 0.85 mm thick) which form 0.1 mm-thick parallel channels. The working fluid is water and the magnetic field source is a Halbach array with a maximum flux density of 1.65 T. A maximum temperature gradient of 4.45 K and a maximum cooling capacity of 3.9 W were measured in tests without and with a thermal load, respectively. The results show trends of the maximum temperature gradient as a function of the utilization factor and of the temperature of the hot source which are in line with those presented in the literature.
