Summary

Magnetic refrigeration technology is a fast-developing cooling technique which is assumed to be capable to replace the traditional vapor-compression technology in terms of efficiency and environmental requirements in the near future. Cooltech has developed a new series of Magnetic Refrigeration Systems (MRS) capable of successfully working into a commercial beverage cooler. For this application, a specific prototype has been implemented in a beverage cooler cabinet. The 500 liters cabinet uses a magnetocaloric system made of NdFeB permanent magnets generating a field of 0.8 T in the air gap and 3 kg of Gd alloys as a magnetocaloric material. /n this paper we present and analyze a set of experimental measurements performed on the en tire system. The air inside the cabinet has been regulated at +4°C, with a dut y rate of the motor inferior at 50%. Actual results demonstrate that magne tic refrigeration is now a technology able to technically respond to the refrigeration market requirements. /n the end, an overview of a high power magne tic refrigeration system will
also be presented.
