「機場捷運地下車站隧道風機系統保證」分為可靠度及可維護度。可靠度是指隧道在發生不同事故情況下(如隧道塞車、火警等),經行控中心監控系統下達指令至各車站建築物管理系統,啟動各類風機運轉之功能性驗證;可維護度是指當維生性設備(如消防泵浦、排煙風機等)故障時,針對可維修能力進行驗證,其主要目的與可靠度相同,均為保障乘客生命財產安全。
機場捷運地下車站隧道風機系統保證辦理情形概述如下:
一、截至104年3月底前,已完成地下車站A7、TSS11A牽引動力變電站~A12~A14a及A21地下車站之隧道風機系統保證作業。
二、執行系統保證作業前,需經施工廠商依不同系統與關連廠商(如中央監控系統、建築物管理系統)及桃園捷運公司進行作業前之協調,取得共識後,土建廠商依契約規定提送系統保證驗證執行計畫,送交監造單位審查核可隨即進入系統保證實地驗證作業。
三、系統保證驗證作業前,需與行控中心確認作業內容,取得核可後,依約定測試內容及時間進入驗證作業階段,同時確認各車站建築物管理系統與中央監控系統保持連線正常,隨即在行控中心及捷運地下車站核對各類風機運轉情形,以確保運轉模式符合功能需求。
四、系統保證作業過程除須與行控中心保持聯繫外,土建廠商須派員至現場查對各類風機及環控電氣電子設備室紀錄運轉情形。
五、機場隧道段風機系統保證之可靠度及可維護驗證標準如圖一。

The "System Assurance of Tunnel Ventilation System in TIAA MRT Underground Stations" factors include reliability and maintainability. The reliability factor refers to the functional verification during accident signals (eg. traffic jam, fire alarm) traveling to the OCC which generates instructions to the building management system (BMS) in respective stations to turn on ventilating machines. On the other hand, maintainability focuses on the functional verification of life-sustaining equipment malfunctions such as fire pumps and smoke ventilators. Both factors are necessary in the system to achieve the goal of protecting the lives and properties of passengers.
Implementation of the System Assurance process of the ventilation system is briefed as follows:
1.Up until March 2015, System Assurance of underground tunnel ventilation systems has been completed for A7 Station, traction power substations A12 to A14a and A21 Station.
2.Prior to executing the System Assurance process, first, the constructor needs to coordinate with Taoyuan Metro Corporation and respective system contractors such as central monitoring system and building management contractors. Next, the civil engineering contractor will submit the system verification execution plan to the supervising unit and then the on-site process will take place.
3.During the on-site process, the OCC has to first acquire approval to start the execution according to the originally proposed time and testing contents. Then, after confirming that the OCC and BMS connections are normal, ventilation machines are tested to ensure their functionality during normal operation.
4.During the System Assurance process, civil engineering contractors need to send representatives on-site to record operational data of the ventilation machines and environmental control electronic devices.
5.The verification standards of reliability and maintainability of this System Assurance process are elaborated as follows pic 1.
