Green is the background color of high-quality development. In order to speed up the construction of green data centers, Hunan Mobile promotes the safe and efficient use of clean energy, with the goal of improving energy management and control and guiding the upgrading of energy structure, focusing on the two key links of low-carbon construction and low-carbon operation and maintenance. On the one hand, it strengthens the energy saving and reduction of data centers. To build power consumption capabilities, we have taken multiple measures to reduce power supply losses and improve equipment efficiency. On the other hand, we have accelerated the energy transformation of 5G base stations. After completing the energy transformation, the 5G base stations can save 30% of electricity consumption, contributing to the realization of carbon peak and carbon neutrality goals. strength.
Data center intelligent system application
Build a green and energy-saving big data center with smart management in mind
In the mobile Internet era, data is the most important resource One, and as a new infrastructure for carrying data, the importance of data centers is self-evident. However, with the vigorous development of the Internet industry, the energy consumption and carbon emissions of large data centers are also increasing. Therefore, it is imperative to build a green data center and reduce data center carbon emissions.
Hunan Mobile gave priority to energy conservation and emission reduction when planning the Zhuzhou data center, and vigorously promoted standardized green energy-saving design from aspects such as architectural layout, appearance structure, and body coefficient. It not only carries out environmental protection assessment in terms of architectural design and material selection, but also adheres to the application of green advanced technology in the selection of supporting equipment such as power supply and air conditioning. The power supply equipment adopts Panamanian power supply technology, with 10KV direct input and DC240V output for ICT equipment. Simplifying complexity, simplifying and integrating several sets of original equipment into one set of equipment, improving power conversion efficiency by 3%, saving electricity bills, saving investment and computer room area, and achieving rapid deployment.
Data center equipment is powerful, but it generates a lot of heat. Servers and processors must be kept below a certain temperature to maintain optimal performance. The air conditioning and refrigeration system becomes a "big consumer" of power. In terms of air conditioning equipment, Hunan Mobile adopts water-cooled air conditioners, water pump frequency conversion, heat pipe cooling and other technologies, and uses high-pressure centrifugal chillers + plate heat exchangers + open cooling tower systems to make full use of natural cold sources in winter and reduce the mechanical refrigeration of chillers operation time, and then superimpose the new air conditioning terminal technology to directly cool the equipment nearby, further reducing the energy consumption caused by refrigeration transmission. The combination of the above technologies has nearly doubled the energy efficiency of the air conditioning and refrigeration system.
New technology application of data center air conditioning
In order to promote intelligent data center operation and maintenance management, Hunan Mobile has built a data center energy consumption management platform and an IDC centralized operation and maintenance platform. Through the analysis building Energy consumption data of buildings, computer rooms, and equipment are used to locate high-energy consumption points such as IT equipment, power supply, and air conditioning. Based on real-time monitoring of IDC business operation data, adaptive tuning and maintenance strategies are output, and through air conditioning operation parameter optimization, main equipment Operation optimization enables each device to operate in the optimal mode for overall energy consumption, which also avoids the increase in overall energy consumption due to local heat island problems, realizes smart cooling, and ensures low energy consumption and high-performance operation of the data center.

The power consumption of a 5G base station is How old? Data from Hunan Mobile shows that the power consumption of base stations accounts for 60% of the energy consumption of the entire mobile communication network, and the power consumption of 5G base stations is three times that of 4G base stations. Therefore, improving the energy saving and consumption reduction level of 5G base stations is an important foundation for 5G development and the communications industry to help the whole society achieve the dual carbon goal.

Hunan Mobile takes the 5G networking architecture as the evolution direction and carries out CRAN transformation of the entire network, adopting the "one station, one cabinet" The low-carbon network construction solution integrates the main equipment, air conditioners, power supplies, and batteries into an integrated outdoor energy cabinet, gradually replacing the traditional civil engineering room, and combines it with the "MIMO power + solar" stacked light operation solution to use solar resources to power the base station. and battery charging, saving the direct use of mains power in the base station, and then introducing MIMO power technology to realize the access to multiple energy sources such as solar energy, mains power, and generator sets to ensure the safe and stable operation of the network.
In terms of the application of new technologies in air-conditioning equipment, through the cabinet-level refrigeration method of "gravity heat pipe type dual-cycle air conditioner + closed hot channel", the equipment is directly cooled nearby, which can save a lot of cooling capacity and reduce energy consumption.
In order to promote green operation and maintenance of 5G base stations, reduce costs and increase efficiency, Hunan Mobile has built a base station energy consumption intelligent management platform based on the integrated energy cabinet, integrating "AI + big data + IoT + power electronics + energy storage" "Technology + Sensing Technology" is integrated to achieve accurate measurement of the power of each device without the need for electricity meters, and the power consumption footprint can be accurately visualized. The smart platform links energy and business, enabling remote power on and off control of equipment and precise air conditioning refrigeration.
"In the future, Hunan Mobile will continue to promote the application of 5G low-carbon base stations." The relevant person in charge of Hunan Mobile said that Hunan Mobile will also conduct research on zero-carbon base stations and increase the promotion of 5G+ energy applications to "energy-saving ", Clean Energy, Empowerment" plan as the outline to help the whole society achieve the dual carbon goal.
