Performance measurements on a large-scale magnetocaloric cooling application at room temperature.

Summary

Cooltech Applications has developed a new range of magnetocaloric cooling applications for industrial chillers. Extensive use of virtual prototyping has led to the definition of the implemented regenerator and to the design of a proof-of-concept machine. To our knowledge, it represents the largest scale magnetocaloric machine ever built by the community. Details on machine features and important improvements are shared.

In this work the numerical model includes thermodynamic irreversibilities. These reality imperfections have been experimentally quantified and the data have been implemented into the simulation model in order to further increase the accuracy of the explored numerical predictions. Finally a campaign of measurements of performance has been carried out on the built machine by an external certified organism. The experimental test procedure, data processing and analysis of obtained results are described and discussed.
