Performance analysis of a single stage four bed metal hydride cooling system, part A: Influence of mass recovery

The concept of mass recovery in metal hydride systems is studied with a single stage multi-bed cooling system as example. Mass recovery results in variation of bed temperatures due to removal or addition of heat of desorption or absorption respectively. Coefficient of performance and cold output increase while required heat input decreases for the mass recovery cycle. Thus mass recovery between hydride reactors is found to improve system performance compared to that of a basic system. © 2002 Éditions scientifiques et médicales Elsevier SAS. All rights reserved.
