複合型吸附轉輪機械強度與吸濕性能評估

台灣位處亞熱帶地區且屬於海島型潮濕氣候，終年環境偏向高濕的狀態，因此各項除濕乾燥系統已成為工業與住商部門的基礎設備。吸附除濕輪具有處理量大、速率快、低露點以及連續吸附和再生操作等優點，是值得投資發展的吸濕元件之一。本研究針對吸附除濕輪的製備，從蜂巢式空輪到吸附劑的塗覆，並在製作完成後與轉輪指標大廠，日本西部技研（Seibu Giken）的除濕輪D-MAX®進行輪體強度與吸濕性能上的比較。結果顯示，利用矽溶膠搭配金屬有機骨架（metal-organic framework, MOF）作為吸附劑，可有效提升輪體中吸附劑的利用率，並且達到與西部技研除濕輪相當的輪體強度與吸濕性能。

Taiwan is located in a subtropical region and has an island-type humid climate with high humidity throughout the year, so dehumidification and drying technologies have become the basic equipment for industrial and commercial sectors. Desiccant wheels are one of the worthy investment components for dehumidification because of their high throughput, high speed, low dew point and continuous adsorption/regeneration operation. In this study, a comparison was made between the mechanical strength and moisture absorption performance of a dehumidifier wheel, D-MAX® from Seibu Giken, a leading manufacturer of rotating wheels, and the honeycomb type wheels with coating of adsorbents. The results showed that the use of both silica gel and metal-organic framework (MOF) as the adsorbent effectively increased the utilization of the adsorbent in the wheel and achieved a comparable strength and moisture absorption performance to the Seibu Giken wheel.
