| Summary: | 碩士 === 國立中央大學 === 機械工程研究所 === 99 === An investigation of adsorption bed using flat-tube in a adsorption cooling system with siliga gel as adsorbent and water as refrigerant is described. The new type adsorption bed is in order to increase the amount of adsorbent and decease the thermal resistance. Otherwise, the performance of the adsorption bed with difference thickness of silica gel coated layer on the flat-tube is discussed.
The results show that the performance of the flat-tube adsorption bed is better than the circular tube. The amount of water adsorbed of flat-tube adsorption is 2.2 times than the circular tube in 10 minutes at adsorption cycle. Otherwise, it is smaller thermal resistance and better performance of mass transfer by thin thickness of silica gel coated layer. It means that the 2.8 mm coated layer has better performance of adsorption and cooling power.
