Summary

This paper presents preliminary results of a magnetic air conditioner prototype tested in a relevant environment compatible with the Technology Readiness Level (TRL) 6. The prototype, which contains all components of a functional cooling system, was experimentally evaluated in an especially developed calibrated calorimeter designed according to international technical standards for testing split-type air-conditioning units. Although the preliminary performance parameters are below values currently exhibited by commercially available air conditioners, the prototype has achieved one of the largest temperature spans and cooling capacities among the magnetic refrigerators presented in the literature. In addition, the study sheds some light on the external irreversibilities associated with the heat exchangers, which can be highly detrimental to the system’s performance and must be taken into account in the design and analysis stages.
