| 中文摘要 | 本文將固態除濕輪併入一直接蒸發冷卻系統中,為了探討除濕輪空調系 統之性能,吾人建立了除濕輪之熱質傳方程式,且建立整個冷卻系統之數學模式 並加以數值模擬,本研究並於再生過程中應用階段再生之觀念以提昇系統之性能 係數。 雖然空調系統之性能係數在ARI之外界條件下可高達18.8,然而,本系統在台灣 夏季應用時必須加以修正,才能維持舒適之室內空氣條件。本研究亦顯示在室外 絕對濕度為0.03kg/kg時,除濕輪空調系統之性能係數通常會低於0.3。 |
| 英文摘要 | A commercial desiccant wheel is incorporated into the DINC (direct- indirectevaprative cooling) system. In order to examine the performance of this desiccantcooling system, the heat and mass transfers of desiccant wheel and the whole cooling system are mathematically modelled and numerically calculated. In this study,the concept of "staged regeneration" is employed for the regeneration process topromote the system's COP(coefficient of performance). Although th COP of the cooling system can be as high as 1.88 under theARI(American Refrigeration Institution) conditions. Under the condition of midsummer weather in Taiwan, the same cooling system has to be modified such thatthe desired comfortable indoor condition can be maintaned. The study also revealsthat the COP of desiccant cooling system is usually less than 0.3 when the outdoorhumidity ratio is as high as 0.03 kg/kg. |
