《GB/T 41783-2022模块化数据中心通用规范》由TC28（全国信息技术标准化技术委员会）归口，TC28SC39（全国信息技术标准化技术委员会信息技术与可持续发展分会）执行，主管部门为国家标准化管理委员会。
Introduction
Core framework and technical characteristics
The standard establishes a system-level infrastructure specification system, and clearly classifies the design according to the dual-row/single-row/compact architecture, among which the modular integration degree PPUE becomes the core technical indicator.
Technical Requirements Analysis
| Core System | Grade A Data Center | Grade B Data Center | Test Methods |
|---|---|---|---|
| Power Distribution System | Dual-Path 2N Redundancy | N+1 Redundancy | Harmonic Analyzer Detection |
| Refrigeration System | n+x Redundancy Topology | Dual Refrigeration Pipes | Pressure Differential Dynamic Test |
| Security System | Ultra-Early Fire Alarm Linkage | Infrasound Monitoring | Intelligent inspection equipment |
Deployment planning recommendations
- In the planning stage, compromise assessment should be prioritized to eliminate electromagnetic interference and geological risks
- CFD simulation should be introduced into the air flow organization design, and the pressure difference between the cold and hot channels should be controlled at 30Pa±5
- In the packaged line design, the maintenance channel should be pre-controlled, and the maintenance opening should be ≥800mm
Energy efficiency evaluation system
Innovatively construct a multi-climate zone modeling test solution, use the track-to-track mapping method to simulate the 35℃/25℃/15℃ characteristic conditions, and introduce the temperature correlation coefficient to accurately calculate the dynamic zhPUE index throughout the year.
Typical case: A supercomputing center reduced the mpPUE equivalent value to 1.28 by improving the refrigerant valve group and active control.
