Effects of operating conditions on reciprocating room temperature magnetic refrigeration system.

Summary
In this paper, the effect of the operating frequency on the cooling span of a reciprocating magnetic refrigeration system, with granular gadolinium (Gd) of particle size 0.3-0.5 mm used as magnetocaloric material, was investigated. The hot and cold end temperatures of an active magnetic regenerator (AMR) were measured over time for different operating frequencies (0.07 Hz, 0.12 Hz, 0.16 Hz, 0.19 Hz and 0.22 Hz) under a constant magnetic field of 1.5 T generated by a permanent magnet. The results showed that the temperature difference between the hot and cold ends increased with the operating frequency increase. Besides, the maximum refrigeration temperature of the system was 12.8 °C for an operating frequency of 0.22 Hz.
