應用加藥處理改善冷卻水水質之研究 – 以A廠為例

Abstract

以空調設備的節能觀點，改善水冷式空調系統的熱交換效率對廠房的投資報酬是可預期的。如果能穩定空調設備的熱交換效率，將可使設備效率損失降至最低，減少不必要的耗水、耗電及維修保養，進而減少不必要的設備投資。 空調冷卻水系統熱交換效率受結垢、腐蝕及微生物的影響甚鉅，如果能有效的管理和控制，將可創造明顯的效益。 本研究係發現在使用自來水為補充水的水源下，即使經由水質軟化處理仍無法有效的解決雜質、菌類等問題，從而使得空調設備的熱交換效率降低。本研究篩選出利用加藥處理進行冷卻水處理的方法並進行實際測試，發現採用生物水處理劑的加藥方法對熱交換效率有極佳的穩定效果，同時解決了腐蝕菌類的問題，而投入的成本相對於節省的能源有極大的效益。

From the perspective of energy-saving in air conditioning systems, the improvement of heat exchange efficiency of water-cooled air conditioning systems on the return of investment is foreseeable. If the heat exchange efficiency of air conditioning systems could be stabilized, the efficiency loss of equipments could be minimized, and unnecessary water consumption, power consumption, maintenance, and services could be reduced. Therefore, unnecessary investment on equipments could be reduced. The heat exchange efficiency of cooling water systems is affected by precipitation, corrosion and microorganisms. If these factors are managed and controlled effectively, significant benefit would be created. This study found that when tap water is used as the source of supplementary water, although the water has been softened, the problems, such as impurities and bacteria, still remain. Thus, the heat exchange efficiency of air conditioning systems is reduced. This research sieve up the way to process the cooling water by dosing chemical & experimentation, we found the biological water treatment is not only effective on stabilizing the heat exchange efficiency but also solving the problem of corrosion & microorganism, and the investment return rate between cost input & energy conservation is greatly.
