机柜级制冷技术应用于C-RAN站点的节能效果分析

Analysis of Energy-Saving Effect of Cabinet-Level Refrigeration Technology Applied to C-RAN Site

目前5G建设中采用C-RAN建设方案,基带处理单元(Building Baseband Unit,BBU)集中部署导致机房局部热点问题突出,采用传统的增加机房空调的方式会造成高额空调电费。针对上述问题,提出机柜级制冷方案,解决局部热点问题的同时降低机房空调能耗。对衢州市C-RAN机房采用多业务一体化节能柜进行了改造并测试了其节能效果。同时,对在全国不同气候区应用多业务一体化节能柜的效果进行了预测分析。

At present,the C-RAN construction solution is adopted in 5G construction.The centralized deployment of Building Baseband Units(BBUs)has led to prominent local hot spots in the communication room.The traditional method of increasing the air-conditioning in the communication room will cause high air-conditioning electricity bills.In response to the above problems,a cabinet-level refrigeration solution was proposed to solve local hot issues while reducing the energy consumption of air conditioning in the communication room.In this paper,the use of multi-service integrated energy-saving cabinets in the C-RAN computer room in Quzhou was transformed and tested its energysaving effects.At the same time,the effect of applying multi-service integrated energy-saving cabinets in different climate zones across the country was predicted and analyzed.
