武漢某數據中心空調系統設計及節能分析
Air conditioning system design and energy saving analysis of a data center in Wuhan
摘要：
分析了武漢地區自然冷卻資源量，介紹了數據中心常規系統流程的運行邏輯，結合完全自然冷卻在時間軸上呈碎片化分布的特性，指出其利用自然冷卻效率較低的原因。為提高數據中心能源利用效率，該項目采用蓄冷罐釋冷混水技術，通過對空調系統進行詳細分析，采用了一種新型混水溫控閥，達到快速混水的目的。IT設備在滿負荷條件下，PUE為1.336，滿足設計要求，節能效果顯著。
Abstract：
This paper analyses the amount of free cooling resources in Wuhan, and presents the operating logic of the conventional system process of the data center. Combined with the fragmented distribution of complete free cooling on the time axis, this paper points out the reasons for its low efficiency in using free cooling. In order to improve the energy efficiency of the data center, this project adopts the water mixing technology with cold storage tank to release cold. The air conditioning system is analysed in detail, and a new type of water mixing temperature control valve is adopted to achieve the purpose of rapid water mixing. Under full load conditions of IT equipment, the data center has a PUE of 1.336, which meets the design requirements and has significant energy-saving effects.
