本文以理論分析及實驗方法探討橢圓管式盤管熱交換器與圓管式熱交換器之性能,分析在高濕、標準、以及加熱之不同環境下對橢圓管式盤管熱交換器與圓管式熱交換器的影響與比較。實驗結果顯示橢圓管式熱交換器在空氣側風速情形1~5m/s之下,當空氣通過盤管時,壓降、熱交換量會隨著正向速度而增加,且熱傳係數、雷諾數及紐賽數也會隨正向速度上升而增加,其中橢圓形的鰭管式熱交換器的熱傳係數會比傳統圓管鰭片熱交換器高6%~13%,橢圓形的鰭管式熱交換器的壓損會比傳統圓管鰭片熱交換器低26%~45%,效果優於一般的圓管式熱交換器,進而改善熱交換器之效能。由熱交換器性能測試實驗所量測數據與計算結果都須經不準度計算誤差修正,此時數據分析得出結論更為準確,當潔淨室的外氣空調箱運轉時每年在能源消耗每年可節省28150.9 MWH。
In theoretical analysis and experimental methods Discussion and performance of the oval tube heat exchanger tube coil heat exchanger, analyzed under different humidity environments, standards, as well as heating of the elliptic tube heat exchanger coil round influence and Comparative tube heat exchangers. Experimental results that under the oval-tube heat exchanger on the air side. Velocity from 1 ~ 5m / s, when the air passes through the coil, the pressure drop, the amount of heat exchange with the forward speed increases, and the heat transfer coefficient, Reynolds New race and the number will rise with increasing forward speed, wherein the heat transfer coefficient elliptical fin tube heat exchanger will be higher 6% to 13% larger than traditional fin tube heat exchangers, oval fin tubes pressure drop type heat exchanger will be 26% to 45% lower than conventional fin tube heat exchangers, better than ordinary tube heat exchanger, thus improving the performance of the heat exchanger.Data measured by the performance test results of experiments on the heat exchanger and are subject allowed calculation error correction, then the data analysis concluded that more accurate when the MAU cleanroom operation each year in energy consumption per year save 28150.9 MWH
