A REVIEW OF ADSORBENTS AND ADSORBATES IN SOLID-VAPOR ADSORPTION HEAT-PUMP SYSTEMS

World-wide efforts to use solid-vapour adsorption technology for heat pumps have been intensified since the imposition of international rest rictions on production and use of chlorofluorocarbons. Yet, to this da te solid-vapour refrigeration and heat pump systems are still under la boratory testing stages. Promising recent developments in Japan, Europ e and the U.S.A. include the use of porous metal hydrides and composit e adsorbents. A review of adsorbents and adsorbates used in various in vestigations on solid-vapour adsorption heat pumps are presented in th is paper, with an aim of initiating a novel concept experimental inves tigation.
