Abstract

This report explains recent magnetic refrigeration technology in low temperatures. As the case study, continuous ADR (Adiabatic Demagnetization Refrigerator) and hydrogen magnetic refrigeration are shown here. Continuous ADR system has been developed to provide the temperatures lower than 0.1K continuously. This system operates the cascade Carnot cycle with very high efficiency of 90% Carnot. The hydrogen magnetic refrigeration consists of Carnot stage for liquefaction and AMR stages for pre-cooling the hydrogen gas. A model study covers from room temperature to liquid hydrogen temperature (20K) is described.
