| 中文摘要 | 本論文旨在探討汽車使用不同的通風與空調模式組合下,對於車內空氣品質的影響性;除測量車內的溫度、相對濕度、二氧化碳、一氧化碳、甲醛及揮發性有機化合物等濃度的變化外。另採用可表達一般人對於熱度感受的熱指數,透過田口方法來尋求最佳的通風與空調模式組合。經由分析結果顯示,在冷氣溫度設定與外界溫度相同的情況下,依照田口方法的設計方式,車外換氣與有冷氣的組合,明顯的可將熱指數從41以上的高度中暑指數,在3分鐘後降低至32以下的中度中暑指數。採用車內循環與車外換氣的通風模式,對於二氧化碳(CO_2)濃度會形成極大的差異,僅30分鐘的差異就會高達43.4%;在只有駕駛一人的情況下,在35分鐘後CO_2的濃度就會超過1000 ppm的建議值。 |
| 英文摘要 | This study investigated the impact of different combinations of ventilation and air conditioning patterns on in-car air quality. In addition to measuring the changes in temperature, relative humidity, carbon dioxide, carbon monoxide, formaldehyde, and volatile organic compound concentrations in cars, this study also adopted the heat index, a measure of the perceived heat, and used the Taguchi method to find the best combination of ventilation and air conditioning. Analysis results showed that when the air conditioning temperature was set at the ambient temperature, the combination of external ventilation and air conditioning decreased a heat index of over 41 to less than 32 in three minutes. The internal circulation and external ventilation pattern greatly influenced carbon dioxide concentrations; a 43.4% increase was seen in only 30 minutes. With only a driver in the vehicle, carbon dioxide concentrations surpassed the recommended 1,000 ppm after 35 minutes. |
