联通哈尔滨云数据中心绿色节能实践
Green energy saving practice in Unicom Harbin Cloud Data Center
摘要：
联通哈尔滨云数据中心基于优越的自然气候条件，结合自然冷却技术，制冷系统利用板式换热器+干冷器运行模式为数据机房提供冷源。运行结果表明，投产初期低负荷运行模式节电29%，达到设计负荷后该运行模式预计年节电量578万kW·h，节电率可达31%。节水效果明显，具有很好的节能效益。

Abstract：
Based on the superior natural climatic condition and the natural cooling technology, Unicom Harbin Cloud Data Center uses the operation mode of plate heat exchanger and dry cooler to provide cold source for the data room. The operation results show that in the initial stage of production, the low-load operation mode saves electricity by 29%. After reaching the design load, the operation mode is expected to save electricity 5.78 million kWh per year, and the power saving rate can reach 31%. The water saving is obvious, and the energy saving benefit is good.
