With the advent of the 5G big data era, network evolution and the rapid development of the data industry, the scale of large data centers(DC) is getting larger and larger, and the power consumption of data centers is also increasing. According to statistics, the national DC electricity consumption in 2018 was 160.889 billion kW/h, surpassing Shanghai's total electricity consumption in 2018, accounting for 2.35% of China's total electricity consumption. Moreover, It is expected to reach 266.792 billion kW/h in 2023, The average annual growth rate will reach 10.64%, which is approximately equal to the power generation capacity of 2.5 Three Gorges.
More importantly, power consumption has become a bottleneck restricting the development of data center services. The following table shows the proportion of energy consumption of each system configuration in the data center. From the analysis of the data in the table, it can be found that in the non-IT energy consumption, about 63% of the loss is caused by the data center cooling system.
