Outline of Final Research Achievements

In order to enhance the heat transfer rate in an adsorbent heat exchanger of adsorption chillers, we studied on the preparation of a silica-coated aluminum composite adsorbent. Mesoporous silica (MPS) particle was employed as an adsorbent for water vapor adsorption, and the particle layer was formed on an aluminum substrate using silane agent CPTS by dip coating. The experimental results showed that a rigid MPS layer with a thickness more than 100μm could be attached on the aluminum plate under appropriate preparation conditions. The silica-coated aluminum composites obtained represented the adsorption capacity to water vapor in the lower relative pressure range. These results indicated that the silica-coated aluminum composite could be a promising adsorbent for high performance adsorption chillers.
