            摘要:

             基于分層抽樣檢測方法和對實測數據進行壞值剔除的格魯布斯檢驗法,對上海地鐵18個不同運行年限代表車站的環控設備與系統進行了研究。分析發現:冷水機組COP在運行初期、中期和遠期分別為3.78、4.64和3.92,呈現中期較高、初期和遠期較低的趨勢;冷卻塔平均熱力性能參數和冷源系統能效比EER呈現中期較大、初期和遠期較小的趨勢;冷卻塔的風機單位風量耗電比在初期和中期差別不大,但在遠期相對初期增大65.4%,差異明顯;冷卻水泵和冷水泵效率在0.85上下波動,均與運行年限無明顯相關性。

            Abstract:

            Based on the stratified sampling test method and the Grubbs test method of removing bad values from the measured data, studies the environmental control equipment and systems of 18 stations with different operation years in Shanghai Metro. The analysis indicates that the COP of the water chiller is 3.78, 4.64 and 3.92 respectively in the initial-term, middle-term and long-term operation of the station, showing a trend of higher in the middle-term and lower in the initial-term and long-term. The average thermal performance parameter of the cooling tower and the EER index of the cold source system show a trend of larger in the middle-term and smaller in the initial-term and long-term. However, the power consumption per unit air volume of the cooling tower has little difference between the initial-term and middle-term, but it increases by 65.4% in the long-term relative to the initial-term. The efficiency of the cooling water pump and the chilled water pump fluctuates around 0.85, which has no obvious correlation with the service life.
