Performance analysis of a single stage four bed metal hydride cooling system, part C: Influence of combined heat and mass recovery

The effects of combined heat and mass recovery on the performance of a single stage multi-bed metal hydride cooling system is studied. A combined recovery cycle which effectively utilizes the advantages of both heat recovery and mass recovery is described. Reduction in sensible heating and cooling requirements along with increased hydrogen desorption results in improvement of coefficient of performance. Operating temperatures exert significant influence on the performance of combined recovery cycle. It is found that combined recovery is more effective at lower heat source temperatures and also at higher intermediate temperatures. © 2003 Éditions scientifiques et médicales Elsevier SAS.
