學生宿舍室內二氧化碳濃度檢測之研究-以既有學校宿舍建築為例

現代人一天當中有八成以上的時間都處於封閉室內環境，包括幼兒所、學校宿舍、住家起居室、飯店客房、辦公室、會議室…等各類型封閉式室內空間。近年在「室內空氣品質管理法」強制推行下，民眾逐漸重視長時間處於空氣品質不良的封閉式室內空間時，對人體健康產生危害等相關問題。身體長期處在封閉式室內空間進行相關活動時，若室內空氣品質不良且通氣量不足，這些看不到的空氣污染源，更容易導致封閉式室內空氣品質的惡化。本研究探討某大學學生宿舍室內空氣品質，採宿舍三樓平面圖依區域設置五個採樣點，其編號分別為A3、B4、C5、D4與E4，瞭解宿舍室內二氧化碳濃度分佈情形，分別探討宿舍室內關門且開窗、關門且關窗二種狀態。設置非分散式紅外線監測儀器，以連續性收集室內二氧化碳數據，透過資料剖析瞭解室內現況分佈。研究發現宿舍無人使用期間，室內二氧化碳濃度平均值約400~500ppm，顯示室內二氧化碳濃度符合標準；在學生入住期間，資料顯示E5房間室內二氧化碳平均濃度最高；其採機械換氣手法，在室內窗戶上方裝設風扇，引入室外新鮮空氣作為改善方法，可有效降低室內二氧化碳濃度。

More than 80% of modern people are in a closed indoor environment, including children's homes, school dormitories, living rooms, hotel rooms, offices, conference rooms, etc. In recent years, under the mandatory implementation of the "Indoor Air Quality Management Law", the public has gradually attached importance to issues related to human health when it is in a closed indoor space with poor air quality for a long time. When the body is in a closed indoor space for a long time, if the indoor air quality is poor and the ventilation is insufficient, these invisible air pollution sources are more likely to cause the deterioration of the closed indoor air quality. This study explores the indoor air quality of a university student dormitory. The three floor plan of the dormitory is divided into five sampling points according to the area. The numbers are A3, B4, C5, D4 and E4 respectively. The distribution of carbon dioxide concentration in the dormitory room is discussed. Close the door and open the window, close the door and close the window. A non-dispersive infrared monitoring instrument is set up to continuously collect indoor carbon dioxide data, and to analyze the distribution of indoor conditions through data analysis. The study found that during the unoccupied period of the dormitory, the indoor carbon dioxide concentration averaged about 400~500ppm, indicating that the indoor carbon dioxide concentration met the standard; during the student's stay, the data showed that the average concentration of carbon dioxide in the E5 room was the highest; the mechanical ventilation method was adopted above the indoor window. The installation of a fan and the introduction of outdoor fresh air as an improvement method can effectively reduce the indoor carbon dioxide concentration.
