摘要
随着通信行业的迅速发展,通信机房的用电消耗持续快速增长。机房空调能耗约占机房总能耗的40%,因此空调能效水平是通信枢纽楼节能的关键。本文以某通信枢纽楼节能改造项目为例,利用“磁悬浮蒸发冷式多联机组+冷媒直膨末端空调+AI智能控制”技术路线,降低空调能耗和整体大楼PUE,实现绿色节能目标。通过改造,PUE可降低至1.42,年节省超过3.5×10^(6)kW·h。
With the rapid development of the communication industry,the power consumption of communication equipment rooms is growing at an alarming rate.In fact,the energy consumed by air conditioning in these rooms constitutes approximately 40%of the total energy consumption.Therefore,improving the energy efficiency of air conditioning systems is crucial for achieving green energy-saving in communication hub buildings.This article presents a case study of an energy-saving renovation project in a hub building.The proposed solution incorporates a"magnetic levitation evaporative cooling multi-connected unit+refrigerant direct expansion terminal air conditioning+AI intelligent control"system.This system aims to reduce air conditioning energy consumption,lower the overall building's PUE,and achieve energy-saving objectives.The transformation project is expected to decrease the building's PUE to 1.42,resulting in an annual electricity savings of over 3.5 million kW-h.These remarkable results demonstrate the effectiveness of the energy-saving measures implemented.
