隨著科技的進步,人們大量依賴現代化設備,其中辦公室影印機逸散之污染物是造成室內空氣污染的主要來源之一,在無法移除污染源的情形下,如何改善室內空氣環境是目前迫切需要解決的問題。有鑑於此,本研究選定室內密閉影印空間進行現場實驗檢測,將檢測數據以MapInfo軟體進行套疊,提供定量污染以瞭解影印作業現場的污染物濃度值與分佈情形,再藉由負離子發生器與污染物反應,評估靜電移除技術中的空氣負離子對懸浮微粒PM2、PM10及臭氧之去除效率與分佈影響。後續藉由變因控制實驗,分析空氣負離子濃度與分佈,以作為改善污染物濃度之進一步探討。 本研究結論如下: 一、空氣負離子去除懸浮微粒PM2污染值達67 %,去除懸浮微粒PM10污染值達50 %,整體效果十分顯著;並且得知空氣負離子對細小微粒有著更佳的去除效果。 二、實驗對照組顯示臭氧自然衰減量大,實驗中空氣負離子去除臭氧減量效益僅達9 %。推估室內換氣率過低乃是主因,故仍需通風換氣以達改善目標。 三、空氣負離子濃度會隨著與負離子發生器之距離而有著區域性的分佈,溼度的差異會影響空氣負離子濃度隨距離衰減之速率,而溫度的差異對空氣負離子濃度並不具有特別影響。
With the advancement of technology, people rely heavily on modern equipment, office of photocopying machines dispersion of pollutants in indoor air pollution caused a major reason for the pollution can not be removed, how to improve indoor air environment is an urgent need to address the problem. Therefore, this study enclosed photocopies of indoor space measured in MapInfo data presentation software stack, pollution to provide quantitative understanding of the field operation of the photocopying pollutant concentration and distribution, follow-up by NAI and pollutant respond, evaluating the removal efficiency and distribution of suspended particles PM2, PM10 and Ozone by Negative Air Ions (NAI). The conclusions were as follows: 1. The NAI removal of suspended particles PM2 reached 67 %, the removal of suspended particles PM10 reached 50 %. The overall effect is very significant; and the NAI for small particles removal of a better result. 2. Experimental control group showed that the natural attenuation of ozone, The NAI removal efficiency of ozone only 9%. Estimating indoor ventilation is the main reason the rate is too low, the ventilation was necessary to achieve the targets for improvement. 3. The NAI density would along with the negative ion generator of distance and have a regional distribution, the difference of humidity will affect the NAI density with distance decay rate, and the difference of temperature to NAI density don't have special influence.
