Study on Optimum Operations of Refrigeration System using Hydrogen-Absorbing Alloys Driven by Solar Heat

To establish technologies for a refrigeration system of a temperature level below -20°C using hydrogen-absorbing alloys driven by solar energy, the simulation technologies capable of modeling the system's performance are developed, and the optimized control method driven by solar heat is studied. The comparison between experimental results and calculated results demonstrates the validity of this model. The effectiveness of a new control method by using switching cycle time is reported with the simulation results.
