兰州某核心枢纽机房节能改造
Energy saving transformation of a core hub computer room in Lanzhou
摘要：
对兰州某核心枢纽机房进行节能改造，改造方案为：对现有空调末端进行改造，在现有空调室外机上增加冷水氟泵模块，通过增加智能集成制冷站提供冷源。过渡季和冬季充分利用自然冷源，集成制冷站压缩机关闭，大幅降低运行能耗；夏季靠集成制冷站提供的冷源与冷水氟泵模块进行制冷循环，空调室外冷凝器关闭，避免风冷空调室外机的热岛效应。改造后机房的电能使用效率降低，装机能力提升，可为其他老旧机房的数据中心化改造提供技术参考。
Abstract：
The energy saving transformation is adopted in a core hub computer room in Lanzhou. The transformation scheme is as follows: the existing air conditioning terminal is transformed, the cold water fluorine pump module is added to the existing air conditioning outdoor unit, and the intelligent integrated refrigeration station is added to provide cold source. In transition seasons and winter,the natural cold source is fully utilized, the compressor of the integrated refrigeration station is closed, and the operating energy consumption is greatly reduced.In summer, the refrigeration cycle is carried out by the cold source provided by the integrated refrigeration station and the cold water fluorine pump module, and the outdoor condenser of the air conditioner is closed,avoiding the heat island effect on the air-cooled air conditioner. After the transformation, the power usage effectiveness (PUE) of the computer room is reduced and the installation capacity is improved, which can provide technical references for the data center transformation of other old computer rooms.
