MAGNETIC REFRIGERATION: AN OVERVIEW.

Author(s) : LACAZE A. F.

Summary

THE DESIGN OF A MAGNETIC REFRIGERATOR BEGINS WITH THE SELECTION OF A CYCLE AND AN ACTIVE MATERIAL. ACCORDING TO THE OPERATING TEMPERATURE, THE CYCLE SHOULD OR SHOULD NO ENTAIL INTERNAL EXCHANGE (REGENERATION). THE ACTIVE MATERIAL HAS TO BE ADAPTED TO THE APPLICATION: DILUTED PERIODS TO ATTAIN LOW TEMPERATURES, CONCENTRATED IF ONE IS SEEKING A HIGH SPECIFIC CAPACITY, ENTROPY VARIATION AND THE HIGHEST POSSIBLE THERMAL CONDUCTIVITY. GENERALLY, ONLY ONE MATERIAL IS USED. THE REFRIGERATOR CAN BE STATIC, ROTARY OR RECIPROCATING. A PARTICULARLY INTERESTING DEVELOPMENT CONCERNS THE ACTIVE REGENERATOR WHICH ENABLES ONE TO USE VARIOUS MATERIALS IN THE SAME CHILLING STAGE. FUNCTIONING IS THEREFORE NECESSARILY ALTERNATIVE.
