近幾年來,由於生產技術的進步與發展,對於產品的高精密度化、小型化之需求更加迫切,因此控制產品所接觸之大氣的潔淨度及溫濕度,使產品能在一個良好之環境空間中生產、製造更是刻不容緩,因此即發展出『潔淨室』,目前世界各國的潔淨室規格各有不同,且隨著時代科技的進步發展而有所修正,然所有潔淨室的目的皆是要將空氣中的懸浮微粒去除,因此瞭解微粒在空氣中之運動及分佈情形對設計潔淨室非常重要。
於第四章控制艙間快速潔淨化各變化參數之交互影響分析中,本研究共進行了:(1)同樣換氣率,不同空間尺寸大小之比對分析;(2)不同換氣率,相同空間尺寸大小之比對分析;(3)換氣率、空間尺寸相同,進排氣擺設位置不同之比對分析;(4)換氣率、空間尺寸、進氣擺設位置相同,排氣擺設位置(Exhaust Port)不同之比對分析;(5)換氣率、空間尺寸、進氣擺設位置相同,排氣方式(Exhaust Slot)不同之比對分析;(6)換氣風率、空間尺寸、進氣擺設位置相同,排氣槽(Exhaust Slot)面積加大之比對分析;(7)空間尺寸、進氣擺設位置相同,進排氣風量不同(QR=1.2QS) 之比對分析;(8)尋求最佳化進排氣風量配比設計,加大不平衡通風(Unbalance Exhaust System)程度,以建立快速潔淨化處理模式,以進一步建立快速潔淨化處理模式。
於第五章射出成形機艙間潔淨度電腦模擬結果分析中以單具FFU風速為0.46m/s並具備單出口之艙間設計最為適當,可作為實際設計採行之重要參考依據。若在不增加成本之考量下,使此FFU具備三段之可調風速,則可同時提供使用者部分節約能源之空間與彈性,一舉兩得。然而,必須充分揭示,在低速運轉下,由於微正壓大量減少,因此不適合在無良好空調控制之室內使用。
In recent years, the demand for higher cleanliness and air quality control of the indoor environment is increasing especially during the manufacturing process. Although different design standards and codes were adapted worldwide, the air flow pattern analysis still dominates the design process.
The parameters affecting the design process were cross-examined, including the air change rate, clean room sizes and layout, air supply and exhaust ports layout, unbalanced supply and exhaust air volume (QR=1.2QS), until system optimization is achieved.
Furthermore, FFU system with 0.46m/s air speed was identified to be appropriate for injection module designs. In order not to increase manufacturing cost, the FFU can be design with three-fiered speed control to provide energy efficiency with space flexibility. However, in low-speed operation, the slightly positive pressure cannot be maintained properly and should be avoided to operate in unconditioned rooms.
