硬膠囊生產線空調系統熱回收節能探討
Heat Recovery and Energy Saving of HVAC in the Hard Gelatin Capsules Production Line.
摘要
硬膠囊生產線常需伴隨恆定的溫溼度及潔淨的空調系統來創造生產作業環境。傳統空調系統為了維持穩定的恆溫恆濕條件，必須耗費大量能源。因此，如何有效降低空調系統中能源的使用，便成為從事空調業者必須重視的課題。本研究即以全自動硬膠囊生產線空調系統為例，就冷卻水廢熱回收、循環迴路(Runaround)盤管熱回收及綜合熱回收節能設計與傳統設計方法作比較，並以動態模擬軟體CVisual DOE4.0分析其耗能結構，做出最佳化之省能設計。結果顯示，以Carrier (E20-II)及CVisual DOE 4.0二套空調負荷模擬軟體，計算尖峰負荷值的相對差異百分比為5.82%；結合冷卻水廢熱回收及循環迴路盤管熱回收的綜合熱回收節能方案為最佳化設計，全年再熱用電耗能，可降低78.6%；全年製冷用電耗能則可降低40.1%；全系統全年耗能可降低25.1%；若不納入製程及照明等非空調耗電，則全年耗能的節能效益更達38%。

In the hard gelatine capsules manufacture environment, always comes along with constant humidity, temperature and pure clean air conditioning. To create such kind of strict operating condition in the product line, the great mass of energy consumed will be the overwhelming issues in the traditional air conditioning system. Therefore, how to reduce the energy consume effectively in the nowadays air conditioning system, become the most important issue in this globalize related industrial application. On this research, an example of automatic hard gelatine product line, it adopts waste heat recycle in the condensing water system, Run-around Coil and Multi-Heat recovery system. Based on these devices to compare with the traditional air conditioning system, by using the CVisual DOE 4.0 software, to dynamic simulate and analyse its energy consumed construct, can find the best optimized way to save the energy. To be accurate this theory, the analysis has been used Carrier E20-II and CVisual DOE 4.0 to dynamic simulating the air conditioning load. There are 5.82% relative differential at the peak load. However, this proves that combines waste heat recycle in the condensing water system and Run-around Coil and Multi-Heat recovery system, will be the best design.As the result shows the system using Multi-Heat recovery devices can reduce heating energy consume 78.6% in a whole year. Meanwhile, the cooling energy consume will reduce to 40.1% as well. In general, the all combined systems energy saving can be cut down to 25.1%. If it doesn’t count in the other generalize power consumption, such as, lighting, process driving motors and other miscellaneous power consumes (non air conditioning energy consumes), the overall effective energy saving ration can be gained to 38% in a whole year.
