Research on Energy-saving Renovation Schemes for Existing Data Center Server Rooms

In order to meet the current requirements for green and high-quality development, it is necessary to carry out energy-saving renovation on the old existing data center computer room. In the China Mobile Information Port No. 1 Data Center Renovation Project, a comprehensive evaluation of the operating status of the computer room was carried out to address issues such as the long distance of the original precision air conditioning supply and the susceptibility to local hotspots. Computational Fluid Dynamics (CFD) simulation software 6SigmaRoom was used to simulate and study energy-saving renovation schemes. By analyzing the air flow organization and energy-saving effects of the air conditioning, the top mounted heat pipe air conditioning+enclosed cold channel scheme was selected to renovate the computer room. By simulating the power consumption within 144 hours after renovation, it was calculated that the PUE factor at the end of the air conditioning system decreased to 0.014, resulting in a power saving rate of approximately ${9 2 \%}$. The research results of this article can provide reference for energy-saving transformation in existing data center computer rooms.
