Experimental studies of near room-temperature magnetic refrigeration.

Author(s) : ROWE A., DIKEOS J., TURA A.

Summary

This work reports on results of experimental studies using an active magnetic regenerative test apparatus in near room-temperature refrigeration cycles. Experiments using regenerator beds composed of three different magnetocaloric materials combined in a layered configuration with applied fields of 2 T have produced no-load temperature spans in excess of 50 K. Regenerator masses range from 45 to 135 grams of rare-earth alloy and aspect ratios are between one and three. An overview of the test apparatus, operating parameters, and performance is described. In addition, the impacts of operation at varying heat rejection temperatures, applied fields of 1.5 T and frequencies between 0.65 and 1.0 Hz are presented.
