Résumé
A zeolite-water heat-pump system has been developed over a 25-year period. Recently, an instant beer-cooling system using the zeolite heat pump system as a commercial product has been developed. The development since the first proposal. has been long The most serious problem encountered in development has been the development of suitable absorbents. The maximum heat exchange capacity to date exceeds 1 MJ/kg for Mg89-A, which is comparable to the energy storage capacity of modern alkaline-ion batteries in weight-bases. But it needs high temperature heat sources (more than 200°C) for activation. Absorbents useful at lower temperatures are thus desirable for effective use of various kinds of lower temperature heat sources. Various nano-porous materials, as well as zeolites, are now under investigation as candidates of heat-pump-absorbents, such as silica-gels, allophane, imogolite, hydrotalcite, etc.
