摘 要
本文主要是利用運轉中之除濕轉輪吸附裝置，試圖改變一些運轉參數以了解對除濕轉輪特性的影響。首先改變轉輪之轉數以觀察其與露點溫度的關係，經由一系列之測試發現露點溫度隨著轉輪之轉數提高而逐漸上升，轉輪之轉數愈高時對露點溫度愈不具影響力。其次是改變再生溫度，經測試後得知再生溫度愈高則脫附速率愈好，反之則愈差，而再生溫度愈高時轉輪在迫擠區（即冷卻區）將無法即時降溫，使該區溫度會漸次升高，導致轉輪轉至吸附區時會有熱量通過該區之介質（如空氣）的現象，因此轉輪若用於空調系統時則須再冷卻而會消耗更多的能源；同時轉輪之轉數改變對脫附效率亦會有所影響。此外，也對通過轉輪之表面風速進行一測試分析，由於通過轉輪之表面風速較低時氣體分子停滯在轉輪之時間比較長，致使水分之吸附效率會較好，反之則較差。
經此測試分析本研究可以提供使用者了解除濕轉輪各種運轉參數之設定，對轉輪之轉數、露點溫度及吸附區溫度變化等之影響，進而提供一套最佳化運轉模式以提高吸附與脫附效率，達成環境保護與能源節約的效果。

Abstract
In this study, we tried to change some operating conditions of desiccating rotor to understand the effect parameters of characteristic of the desiccators. First, we find if we increase the rotational speed of rotor, the dew point temperature will be increased, the higher of rotational speed are, the lower of effect dew point temperature is. Second, the higher of desorbed temperature are, the larger of absorbed efficiency is. On the other hand, the lower of desorbed temperature are, the litter of absorbed efficiency is. Being the temperature of purge zone (or called cooled zone) can’t decrease at time, when we increase the desorbed temperature of desiccating rotor. This phenomenon will increase the temperature of passing medium (i.e. air) when the rotor revolute to next circulation zone. If the desiccating rotor is used in A/C system which will require energy consumption more to cool passing medium (i.e. air). Besides, the variation of rotational speed will have some effects to absorbed efficiency. Finally, we have take a series tests with the passing medium face velocity, the lower of face velocity are, the longer of holding time is. That is to say, the absorbed efficiency will be get better if the passing medium (i.e. air) stay in desiccating rotor has a long time.
From this test and analysis, the results can tell us how to decide the effect parameters of characteristic of the desiccators, sush as rotational speed of rotor, dew point temperature, and desorbed temperature. And then supply an optimum operating model to improve the absorbed and desorbed efficiency to protect environments and energy saving.
