| Abstract Scope |
New magnetocaloric materials are commonly characterized only with respect to their basic magnetic properties. This makes it difficult to predict materials’ performance in a magnetocaloric heat pump because heat transfer models require other parameters that are not routinely measured and may change after processing into an active magnetic regenerator. The key features of CaloriSMART include i) small (approximately 5 ml) volume of regenerator; ii) direct comparison of regenerator performance at two different maximum magnetic field strengths; iii) broad range of operating frequencies, fluid flows, and fluid flow profiles; and iv) rapid, fully automated testing, with most materials and regenerators evaluated in as little as two days. This research is supported by the Office of Energy Efficiency and Renewable Energy of the U.S. Department of Energy (DOE) through the Advanced Manufacturing and Building Technologies Offices. Ames Laboratory is operated for the U.S. DOE by Iowa State University under Contract No. DE-AC02-07CH11358. |
