一、閉式承壓水蓄能設備

1、蓄冷罐制造須由有壓力容器制造資質的定點廠家完成。

2、設備出廠需由國家權威機構進行的性能檢測。

3、設計制造應遵守國標GB150-2011,罐體焊接需滿足《鋼制壓力容器》(GB 150-2011)等國家標準規范要求。

4、廠家蓄冷裝置應具有獨立知識產權,并已獲得專利證書。

5、廠家需出具蓄冷罐的結構計算書,并提供深化設計圖紙。

6、水蓄能罐的有效容積不低于80%。

7、廠家需出具布水器深化的布水器水力計算書(包含溫度、阻力、流速、等指標參數,并采用專業軟件對蓄冷罐在本項目工況下的蓄冷及釋冷狀態進行演示模擬)。

8、廠家需出具蓄冷罐保溫的計算書,并且要高于以下標準。根據《供冷供熱用蓄能設備技術條件》(JG/T 299—2010)要求,蓄冷設備24h熱損失率應小于5%,蓄熱設備24h熱損失率應小于6%。

9、蓄冷罐需安裝溫度測量系統,用于監測蓄冷罐放冷速率情況,溫度傳感元氣件采用知名品牌通用元氣件。

10、由于數據中心應急冷源系統流量大,放冷時間短,系統保障系數高等要求,這對布水器的設計和施工提出很高要求,蓄冷罐布水器一定要滿足使用要求。

2、廠家蓄冷裝置應具有獨立知識產權,并已獲得專利證書。

3、廠家需出具蓄冷罐的結構計算書,并提供深化設計圖紙。

4、水蓄能罐的有效容積不低于80%。

5、廠家需出具布水器深化的布水器水力計算書(包含溫度、阻力、流速、等指標參數,并采用專業軟件對蓄冷罐在本項目工況下的蓄冷及釋冷狀態進行演示模擬)。

6、廠家需出具蓄冷罐保溫的計算書,并且要高于以下標準。根據《供冷供熱用蓄能設備技術條件》(JG/T 299—2010)要求,蓄冷設備24h熱損失率應小于5%,蓄熱設備24h熱損失率應小于6%。

8、罐體基礎需滿足《鋼制塔式容器》(JB/T4710-2005)標準要求。

9、竣工后施工單位應向建設單位提交下列技術文件:

1)材質合格證明書。

2)基礎復測記錄。

3)隱蔽工程(封閉)記錄

4)儲罐幾何尺寸檢查記錄

5)蓄能罐強度及嚴密性試驗記錄

6)蓄能罐試水沉降觀測記錄

7)儲罐底板真空試驗記錄

8)焊縫滲透探傷檢查記錄
