B站R2-AZ2定制化数据中心：预制化模块与智能节能技术实践
Bilibili's R2-AZ2 custom data center uses prefabricated modular containers and advanced liquid cooling, AI monitoring, and other green technologies to deliver 35 MW capacity with PUE under 1.2, supporting China's carbon‑peak/neutrality goals while enabling rapid, scalable deployment.
This article presents Bilibili's R2-AZ2 custom data center project, a comprehensive case study on green data center construction and operation. The project addresses China's "30-60" dual carbon goals (carbon peak by 2030, carbon neutrality by 2060) while meeting rapid business growth demands.
Project Overview: The R2-AZ2 data center project plans approximately 35 MW of IT capacity, with Phase I and II each delivering 1,000 high-density cabinets, and Phase III completing 15,000 cabinets by end of 2022.
Prefabricated Modular Delivery: The project innovatively applies modular container solutions including IT containers, power distribution containers, cooling station containers, and diesel generator containers. These modules are factory-prefabricated and pre-tested, enabling rapid deployment. The entire delivery from civil structure completion to business acceptance took only 3 months for Phases I and II.
Energy-Saving Technologies:
Efficient Cooling Systems: Combines chilled water systems with indirect evaporative cooling, high-efficiency refrigerant pump systems, and liquid cooling technology to achieve annual average PUE below 1.2.
Liquid Cooling Technology: Deploys 76 cold-plate liquid cooling cabinets with 25kW per cabinet. The system achieves design PUE as low as 1.1 by eliminating traditional chillers, storage tanks, and末端空调. Cold-plate liquid cooling uses liquid介质 for heat transfer, with CPU and high-power components cooled via liquid cold plates while other components like hard drives use air cooling.
Intelligent Monitoring: Implements comprehensive infrastructure monitoring and AI-powered energy optimization systems, enabling real-time energy consumption monitoring and continuous PUE optimization.
Future Directions: The project explores technologies including high-voltage DC power supply, direct city power supply, AHU (indirect evaporative natural cooling), refrigerant pumps, waste heat recovery, liquid cooling, AI control, and photovoltaic energy storage to achieve agile delivery and responsive system architecture.
