Optimal Temperature -Entropy Curves for Magnetic Refrigeration

  • Chapter
Advances in Cryogenic Engineering

Part of the book series: A Cryogenic Engineering Conference Publication ((ACRE,volume 33))

Abstract

Magnetic refrigeration utilizes the temperature dependent entropy change produced in a ferromagnetic or paramagnetic material when subjected to a change in magnetic field. By blending different materials together the temperature-entropy (T-S) behavior of the refrigerant may be tailored to maximize system performance. Optimal T-S diagrams for magnetic refrigerators using Carnot, Ericsson and Brayton cycles were determined and compared to results of thermodynamic numerical models.
