超疏水性在結露狀況下對氣冷式熱交換器性能的影響

為了解決Laboratory data的問題，作者莫尼實 這樣論述：

濕空氣冷凝是熱管理系統中常見的過程，在冷凍空調循環中尤為重要，冷凝現象發生於當熱交換器，特別是蒸發器，在低於空氣露點的溫度下操作時。此現象將會導致鰭片側的冷凝液滴(膜)滯留(retention)與橋接(bridging),進而造成風機壓降與能耗的增加。本研究旨在開發一種超疏水熱交換器，通過其疏水特性，最大限度地減少冷凝水的滯留和橋接。本研究提出一種新型的超疏水性鰭片換熱器設計構想，採用傾斜鰭片排列以達到最小壓降和最大節能效果。本研究從熱傳與壓降性能的觀點切入，將新型超疏水性傾斜鰭片換熱器與其他換熱器作比較分析，分別為：超疏水水平鰭片換熱器、親水性傾斜鰭片換熱器、與親水性水平鰭片換熱器。此外，

本研究藉由改變不同的操作條件，如：進氣溫度、相對濕度和鰭片間距，對這四種換熱器進行性能測試。親水和超疏水換熱器中分別以膜狀冷凝和滴狀冷凝模式為主。由於其表面的高潤濕性，親水換熱器會有較大的液滴脫落直徑。相比之下，超疏水換熱器中發生的 Cassie-Baxter 液滴模式，促使了較小的液滴脫落直徑。本研究建立了一個力平衡模型來分析液滴脫落直徑，模型參數包括了表面張力、慣性力與重力對液滴的影響。本研究基於韋伯數(We)與邦德數(Bo)與液滴脫落直徑，引入了一個新的無因次參數( )，該無因次參數 可預測表面的凝結水脫落能力，在給定的鰭片間距下， 越小代表凝結水脫落能力越好。研究結果表明，滴狀冷凝的

超疏水換熱器在濕空氣下的冷凝熱傳性能相較膜狀冷凝的親水性換熱器並未有顯著的提升，此結果可歸因於非凝結性氣體效應。然而，在壓降方面，超疏水性換熱器與親水性換熱器相比，可帶來高達70%的壓降降低，大幅提升節能效果。壓降的降低歸因於聚結誘發的液滴跳躍現象，使得冷凝水連續脫落。

開孔地板對小型資料中心氣流均勻性的影響與能源消耗之實驗研究

為了解決Laboratory data的問題，作者徐伯豪 這樣論述：

本文透過在小型資料中心中採用高架地板供風的設計，使用不同開孔率的開孔地板來實驗研究半封閉冷通道和全封閉情況下，機櫃進風量的均勻性對機房整體冷卻性能的影響。另外，特別研究了冷空氣的分配與使用性，針對冷空氣的洩漏問題進行實驗及分析。研究結果顯示在半封閉冷通道的情況下，使用阻力較大（開孔率較小）的開孔地板可以使氣流分佈更為均勻，但是會導致通道壓力增加而加劇冷空氣洩漏，使得氣流無法完全使用而造成能源的浪費。若採用散熱表現較佳的封閉式冷通道，使用開孔率較大的多開孔地板，調整開孔率由32 %提升至50 %，反而增加了氣流的均勻性，使得機櫃出口的最高溫由58.6 ℃下降至51.3 ℃，溫度的均勻性則提升了

12 %；同時，高架地板下方通道的壓力也大幅下降，通道壓力由21 Pa下降至7 Pa，這將減緩氣流在冷通道的洩漏問題，使得機櫃入口供風量的使用率由91 %提升至96 %。當機房存在著穩定且均勻的氣流之後，便嘗試改變系統供風量，以探討其能源表現的影響。實驗結果顯示降低30 %的系統供風量，空調系統的總消耗功率將節省約8.9 %，使得PUE（能源使用效率）由1.41下降至1.37。降低系統的供風量會使得冷通道內的壓力梯度有所變化，在半封閉冷通道的設計下容易產生熱回流的現象，使得通道末端的機櫃存在SHI為5～15 %的散熱表現。另外，嘗試調整空調系統的冰水溫度以探討對冰水主機能源消耗的影響。結果顯示

提升冰水溫度2 ℃，由15 ℃提升至17 ℃，可以節省約4.9 %的空調系統總消耗功，PUE（能源使用效率）則由1.41下降至1.38。調整冰水溫度將影響機房的系統供風溫度，這將改變機櫃整體入出口的平均溫度，容易在可預期的區域之中出現局部高溫熱點。
