A multi-hydride thermal wave device for simultaneous heating and cooling ha
s been built and investigated. Seven different metal hydrides have been imp
lemented on the high temperature side and two on the low temperature side.
First experimental results with a hydrogen load of about 60% of the maximum
hydrogen inventory showed the feasibility of the concept. The performance
values are in the range of the predicted data, i.e. during the cooling peri
od, a coefficient of performance (COP) of 0.60 has been obtained at cooling
temperatures between 0 degrees C and 10 degrees C, while the average cooli
ng power was about 360 W. With nominal hydrogen load, higher values can be
expected. (C) 1999 Elsevier Science S.A. All rights reserved.
