Abstract:	研究目的是製作一個以水-矽膠為吸附配對的小型吸附式空調系統並測試其性能。比較兩種吸附床、兩種冷凝器對及冷卻水溫度對性能的影響。由實驗結果發現，比較扁平管吸附床與扁平鰭管吸附床，扁平管製冷量為1.808 kW，扁平鰭管吸附床製冷量為2.216 kW，增加鰭片面積可提升製冷量22.5%，但鰭片增加了吸附床的金屬熱容，導致COP下降。比較不同冷凝器對性能的影響，四層冷凝器較三層冷凝器的熱傳面積增加了33.3%，製冷量可提高8.2%。冷卻水溫度對性能有顯著的影響，冷卻水30oC時的製冷量為1.283 kW；冷卻水25 oC時製冷量為1.808 kW，降低冷卻水溫度，製冷量可提升40.9%。The main purpose of this research, a silica gel-water compact adsorption system is designed and the system performance is measured. Two different adsorption beds and condensers are tested in the experiment. The experimental shows that performance, the cooling capacity of flat-tube adsorption bed is 1.808 kW, the cooling capacity of flat-fin-tube adsorption bed is 2.216 kW, respectively. The cooling capacity of the flat-fin-tube adsorption bed is about 22.5% higher than that of the flat-tube adsorption bed .And COP of flat-fin-tube adsorption bed doesn’t increase because the fin increase the metal capacity The cooling capacity is boosted by about 8.2% when the heat transfer area of condenser boosted about 33.3%. The test results show that cooling water temperature has significant effect on performance. When the cooling water temperature is 30℃, the cooling capacity is 1.283 kW. When the cooling water temperature is 25℃, the cooling capacity is 1.808 kW. The cooling capacity increased by 40.9%.
