摘要：

Influence of heat recovery on the performance of a single stage multi-bed metal hydride cooling system is studied with Zr0.9Ti0.1CrFe and Zr0.7Ti0.3CrFe 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 effects Compared to the basic cycle, the coefficient of performance of heat recovery cycle improves by about 15% to over 75% depending on the operating temperatures.
