TAB/ Cx應用於辦公大樓儲冰系統運轉效率改善之研究
TAB/Cx Application in the operating efficiency improvement of ice storage system in office building
摘要
TAB/Cx(Testing Adjusting and Balancing /Commissioning, Cx) 之主要精神在於空調系統整體性能之確認，起自設計、施工、安裝、功能測試、系統操作維護及達成設計目的之整體性能。本文以台北市某辦公大樓之實例說明儲冰系統效率經TAB/Cx具有提高儲冰量、節省電費、有效降低契約容量及舒緩限電危機等優勢。利用DOE-2軟體模擬將結果進行比較分析及探討TAB/Cx之執行要點及改善成效，說明其對業主之利益，設計、監造及營建管理(PCM)單位所需具備之專業及對工程業者品質之提升。希望藉此以客觀模擬及實測數據提供各界重視TAB/Cx的重要性以及盡最大努力將驗收之儲冰系統調校到原設計之目的，其結果顯示，執行TAB/Cx使儲冰空調系統之儲冰量提升924RT-HR，進而達到設計參考值，不僅使設備發揮至最佳效能及使用壽命，並可避免設備不當選用進而增加運轉成本。利用軟體模擬e-Quest將設計值與實測值結果進行耗能及電費分析比較，結果得知當設有儲冰設備之空調系統，總耗能隨儲冰量增加而增加但電費隨之減少。最後再將軟體模擬及執行TAB/Cx驗證前後所節省運轉成本經手算結果相互比對證實其誤差值接近。

The major spirit of TAB/Cx is confirmed that the entirety function and performance of HVAC system since design, construction, install, functional test to system operation and maintenance and achieve the whole function of design intent.This article illustrates the ice storage system with TAB/Cx to raise the advantageous that ice storage volume, saved power bill, reduce contract volume effectively and spread the limited power crisis etc. by the example of office buildings in Taipei. With the DOE-2 software simulation result to discuss the TAB/Cx achievement points, it illustrates the benefit to owner, the necessary professional of design, supervisor and PCM Unit and the improvement quality of Construction businesses. Hope to supply the objective simulation and actual teat value to supply the all walk of life for pay attention to the importance of TAB/Cx and try the best effort to adjust the original design intent with accepted ice storage system for the devices works with optimize and reduce to waste energy to achieve the stuff feel comfortable in the building.The result indicates that the ice storage HVAC system raises 924RT-HR ice storage volume has been implemented TAB/Cx and then to achieve the design reference values. It not only makes the equipments develop the optimum efficiency and useful life, but also avoids improper selection equipment to add performing cost. Compare the consumption and power bill of the design values and real testing result with e-Quest software simulation, the result is that when the HVAC system installed ice storage equipments, the total consumption follows the ice storage volume add, but the power bill reduce. Finally, compare the result and verify the inaccuracy value is closed by the software simulation and the saved service cost that the before and after implement TAB/Cx commission.
