碩士 === 國立臺北科技大學 === 能源與冷凍空調工程系碩士班 === 104 === 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
