Simultaneous Transport of Heat and Adsorbate in Closed Type Adsorption Cooling System Utilizing Solar Heat

Abstract

Quantitative analyses are tried for the simultaneous transport of heat and adsorbate in the operation of a closed-type solar-powered adsorption cooling system. Experimental results obtained with a small-scale unit are successfully interpreted by the model proposed here, which takes into account adsorption properties of a combination of adsorbate and adsorbent employed in the system, structures of the equipment, and its operating conditions. Also, the coefficient of performances of the system of various conditions are estimated by numerical simulations on the basis of the model. Structures of the container of adsorbents are optimized to provide larger COP.
