進氣系統之數值模擬

Abstract

在空調箱系統設計中，最初設計皆為單純外氣進入空調箱作調整，此方法因外氣條件通常都和室內條件差距很大，往往需耗費很大的能量來達到所需的條件，更改設計成利用循環空氣與外氣混合後再進入空調箱調整，可以節省設備空間且循環空氣的狀態幾乎與室內狀態相同，所以可以運用循環空氣的熱能與新鮮空氣混合，大幅降低加熱器的功率。本研究以混合式空調箱運用調整外氣風量與循環風量的配置，並且在維持良好空氣品質、所需最小換氣量下，分析空調箱的冰水盤管冷卻除濕、加熱器加熱與風機運用的能量消耗，討論如何設計達到最節能的效果。最後目標為監控室外環境溫、濕度與訂定室內環境條件，即可快速計算最佳節能的配置設計，達到實用化的成果。

Originally designed are simple outside air into the air-conditioned units to make adjustments in the system design of the air-conditioned units. This method because of they are usually a large gap between the outside air conditions and indoor conditions, it often takes a lot of energy to achieve the required conditions. Changes designed using the circulating air and the outside air mixed before entering the adjustment of air-conditioned units, you can save equipment space and the state of the circulating air is almost the same as the indoor state, so be able to use the thermal energy of the circulating air with fresh air mixed, significantly reducing the heater power. In this study, the mixed air conditioning units use adjust the amount of fresh air and circulating air configuration, and in maintaining air quality, the required minimum amount of ventilation, the analysis of the ice-water coil cooling and dehumidifying of the air-conditioned units, heated by a heater and fan use energy consumption. The final objective is to monitor the outdoor ambient temperature, humidity and set indoor environmental conditions can quickly calculate the optimal design of energy - saving configuration to achieve practical results.
