摘要(中) 本研究藉由重量量測法(load cell)量測新型沸石FAMZ05與金屬有機架構MOF(Metal-organic frameworks)在低溫熱源驅動之水汽吸附性能實驗,並以常壓及真空腔體內之兩種不同環境下,與傳統沸石(13X、Y、ZSM-5、SAPO)和矽膠相互做比較來得出在不同工作溫度壓力下之等溫吸附曲線圖,找出各吸附劑在額定製冷條件下之吸附率差,以利將來吸附床在吸附式空調系統內之設計。從實驗結果顯示,在常壓下以Y型沸石有較佳之吸附速率,只需3小時即能達飽和狀態,較適合運用於短循環時間之吸附式空調系統。SAPO型沸石則有最大之吸附量,在8小時之吸附率約0.27 g/g,後面仍持續吸附,適合運用於長循環時間之吸附式系統。真空腔體方面,MOF與FAM Z05相較於其他吸附劑在60 oC即能脫附水氣,表示在低溫熱源驅動下就能進行脫附作用,因此有機會應用於吸附式空調系統中。最後以常見冷凍空調系統之額定製冷條件進行吸脫附比較,發現金屬有機架構MOF有最佳之吸附率差0.27 g/g,因此將來吸附床在吸附式空調系統內之設計以MOF為最佳之吸附劑。
摘要(英) The goal of this study is to measure adsorption performances for water vapor in the case of FAM Z05 and MOF (Metal-organic frameworks) by using gravimetric method (load cell). The study was conducted under two different environments, which are atmospheric pressure and vacuum. In addition, more materials, such as traditional zeolites: 13X, Y type, ZSM-5, SAPO and silica gel, were used to compare adsorption performance for water vapor under the same environments. The adsorption rate differences for each adsorbent under the air conditioning condition were calculated. It could highly improve the design for adsorption bed in adsorption system in the future.

According to the result of the study, Y type zeolite had the best adsorption speed. It only needed three hours to reach saturated state, and so it is more applicable in adsorption systems with short cycles. SAPO zeolite had the best adsorption rate, the adsorption rate for SAPO zeolite is 0.27 g/g in eight hours. It could still adsorb water vapor after eight hours, and it is applicable in adsorption systems with long cycles. In vacuum chamber, comparing MOF and FAM Z05 with others, MOF and FAM Z05 desorb water vapor at 60 oC, which means they could desorb water vapor at much lower temperature. Therefore, it becomes more desirable in terms of adsorption system. Comparing adsorption rate differences under various air conditioning condition, MOF has the best adsorption rate difference. As a result, MOF might be a good design for coating adsorption bed in the future.

Keyword: gravimetric method, adsorption system, zeolite, FAM Z05, MOF.
