  • How to innovate the planning and design of data center under the trend of "double carbon"?
    May 13, 2022
    With the development of digital economy, the scale of data center industry has further expanded and energy consumption has increased rapidly. In order to deal with the relationship between development and energy saving and ensure the realization of the "double carbon" target, data centers are constantly exploring the potential of energy saving and emission reduction in terms of construction mode, technology, standard and renewable energy utilization. The planning and design, as the beginning of data center construction, is an essential part of promoting energy saving and emission reduction in data centers. The carbon emissions of data centers are mainly due to the consumption of electrical energy, and the total electricity consumption of China's data centers reached 200 billion KWh in 2020, accounting for more than 2.7% already. It is expected that the proportion will double to 4.05% by 2025. In this case, to reduce carbon emissions, it is necessary to further increase the proportion of new energy use. The data center has made various attempts in planning and design, and there are innovative practices, such as the application of "source-net-load storage", which can reasonably plan energy storage through the synergy between the supply side and the use side; for example, the CenturyLink Foshan data center energy storage pilot project is the first time in China to successfully apply new large-scale energy storage technology to a large data center. For example, the CenturyLink Foshan data center energy storage pilot project is the first time in China to successfully apply new large-scale energy storage technology to a large data center. Data center energy storage systems show a good development trend, however, it should also be noted that there are still numerous difficulties in the development of energy storage systems. Therefore, the problem needs to be solved by considering the following points: First, the combination of planning, design and technology promotes the reduction of energy consumption of the cooling system. Data centers generate a lot of heat during operation, and in order to ensure the normal operation of cabinets, cooling and heat dissipation are required, and a significant portion of data center energy consumption is used for this purpose. Through planning and design, choosing a reasonable refrigeration system is an effective means to reduce energy consumption and PUE, and the influencing factors include site selection, building scale and mode, technology maturity, etc. Second, strengthen planning and renovation to promote energy saving in built data centers.In order to achieve energy saving and emission reduction in data centers, the state and many localities have set goals such as energy efficiency development. For example, the "Implementation Plan for the Coordinated Development of Data Centers in Beijing (2021-2023)" issued by the Beijing Municipal Bureau of Economy and Information Technology proposes that, according to the general idea of "four batches", by closing a batch of functionally outdated data centers, integrating a batch of scattered data centers, transforming a batch of high-consumption and inefficient data centers, building a batch of new The goal is to build the world's leading high-end data center development cluster with intensification, greening and intelligence. In order to further realize energy saving and carbon reduction, data centers must take relevant factors into consideration in planning and design, including energy storage and cooling. With the maturity of technology and the improvement of related solutions, data centers will further promote energy saving and emission reduction through planning and design.
