IMPACT OF THE INTEGRATION WORK ON THE PERFORMANCE MEASUREMENTS OF THE MAGNETOCALORIC COOLING SYSTEM AND ITS TARGET REFRIGERATED CABINET

摘要

Cooltech Applications has completed the construction and tests of a new Scale-up rotary magnetic coolingrnsystem. This specific prototype has been designed for research purposes. Its modular architecture has beenrnused to generate improvements on the results to be integrated into the more compact commercial devices.rnThis system uses NdFeB permanent magnets providing a peak field of 0.8 T in the air gap and 3.1 kg ofrnparallel plates of Gd alloys. On the technology roadmap focused on the integration inside a targetrnrefrigerated cabinet, external liquid/air heat exchangers and airflow configurations have been identified asrnkey drivers. In this paper the performance of this latest interfaced system is reported for a liquid flow rate ofrn6 liters/min. Actual measurements demonstrate that it was achievable to reach the target specification of thernfirst application from industrial partners: to cool an air volume of 350 liters down to a temperature of +2℃.
