Résumé

The influence of heat recovery on the performance of a single-stage multi-bed metal hydride cooling system was studied with Zr(0.9)Ti(0.1)CrFe and Zr(0.7)Ti(0.3)CrFe as high and low temperature alloys respectively. The heat recovery cycle effectively utilizes the sensible heat contained in the beds at the end of desorption and resorption processes thereby reducing the heat input and increasing the refrigerating effect. Compared with the basic cycle, the COP of heat recovery cycle improves by about 15 to over 75%, depending on the operating temperatures.
