Study on the Development Status and Challenges of Underground Data Center Construction

Data center is an important part of promoting the whole society to be highly digitized and informationized. Its reliability and security are very important to the normal operation of the country or enterprise. Due to the high environmental sensitivity and high energy consumption, the location and energy saving of data center has always been the primary and key problem of the whole industrial chain. With the successful completion of some large tunnel type underground data centers in China, the advantages of underground data centers, such as high concealment, low energy consumption, anti-interference and low pollution, have gradually attracted people’s attention. Compared with ordinary underground engineering, large underground data centers involve more complex majors and disciplines, and the operating environment is more severe. In view of the future development of data center in the direction of high standard, low energy consumption and green, this paper comprehensively summarizes the development and research status of underground data center at domestic and abroad, and analyzes the classification and related specifications, from the perspective site selection area and construction process, energy consumption demand and cooling technology, energy consumption demand and cooling technology, green data center, this paper summarizes and analyzes the development trend of data center and the characteristics of underground construction, and puts forward the problems and challenges faced by the construction of underground data center in four aspects: collaborative demand of energy saving and environmental control, suitability transformation of existing underground caverns, new underground caverns, intelligent early warning and prevention and control. The development and utilization of underground space is not only a simple space expansion, but also a functional demand. This paper aims to provide ideas for the construction of large underground data center in the future, and also hope to provide reference direction for the development and utilization of functional underground space.
