Abstract

Adsorption process forms the core of adsorption chiller and desiccant dehumidifier. In the conventional adsorption machines, adsorbent is embedded in between heat exchanger fins by wire meshes. Poor contact between adsorbent material and metal fins, and among adsorbent solids incurred in such method significantly impedes heat transfer efficiency, and hence the performance of the adsorption machines. The presented work is aimed to improve heat transfer of an adsorbent embedded heat exchanger by introducing binder. Several organic or inorganic binders are tested with adsorbent silica gel 3A and aluminium pieces, among which it is found that Hydroxyethyl cellulose (HEC) is the most suitable. Experiment is conducted to study the influence of the binder on the overall heat transfer coefficient of the heat exchanger. The results show that a significant improvement of heat transfer is observed with respect to both value and time.
