Résumé

Cooltech Applications has completed the construction and tests of a new Scale-up rotary magnetic cooling system. This specific prototype has been designed for research purposes. Its modular architecture has been used to generate improvements on the results to be integrated into the more compact commercial devices. This system uses NdFeB permanent magnets providing a peak field of 0.8 T in the air gap and 3.1 kg of parallel plates of Gd alloys. On the technology roadmap focused on the integration inside a target refrigerated cabinet, external liquid/air heat exchangers and airflow configurations have been identified as key drivers. In this paper the performance of this latest interfaced system is reported for a liquid flow rate of 6 liters/min. Actual measurements demonstrate that it was achievable to reach the target specification of the first application from industrial partners: to cool an air volume of 350 liters down to a temperature of +2°C.
