【Abstract】 The thesis is concentrated on the heat transfer mechanisms of fixed bed in the adsorption-cooling system. A thermal conductive composite of polyaniline and adsorbent can increase the thermal conductivity by approximately 4-10 times that of pure adsorbent with the little influence on the adsorption performance. The research introduces a all-rounded method to enhance the heat exchange with little influence on the adsorption performance: restructured shaped adsorbent used to enhance the heat transfer of the fixed bed layers; heat conduct glue to decrease effectively the thermal contact resistance between the adsorbent and the adsorber, and the method makes the adsorption-cooling system industrialization probably.更多还原
