Introduction

Standard Framework and Technology Evolution

For the first time, this standard takes business demand orientation as the core principle of data center design. Compared with the traditional YD/T 2441 standard which focuses on infrastructure, it presents three major innovations in architecture:

Comparison dimension	Traditional standard	This business-oriented standard
Design starting point	Infrastructure compliance	Business scenario matching
Energy efficiency index	Single PUE requirement	PUE+WUE+CUE three-dimensional system
Technical path	General Solution	Modularization + Liquid Cooling Customization

Analysis of Core Design Elements

4.2 Site Selection Specifications

For the first time, the requirement of 300-meter tap water supply radius is clarified, and the minimum distance from the source of danger is stipulated:

• Subway line ≥100m
• Gas station ≥400m
• First-level oil depot ≥500m

5.8 Liquid Cooling System Requirements

Detailed three types of liquid cooling technical specifications:

Immersed liquid cooling must comply with the sealing requirements of YD/T 3979, and the boiling point of the coolant should be higher than 150℃; class=instrument>Cold plate liquid cooling According to the requirements of YD/T 3980, the leakage detection response time is ≤30 seconds; the spray system needs to be equipped with a double filtration device.

Energy-saving indicator system

Establish a four-level energy efficiency evaluation model:

Indicators	First year requirements	Next year requirements	Measurement method
PUE	≤1.4	≤1.3	Total IT equipment power consumption/total energy consumption
WUE	≤1.6L/kWh	≤1.4L/kWh	Water consumption/IT power consumption
Rack utilization	≥70%	≥90%	Actual shelf power/design power

Transformation implementation path

13.1 Key transformation nodes

1. Power supply and distribution system: Prioritize replacement of UPS equipment with efficiency <96%
2. Refrigeration system: Increase the utilization rate of natural cooling source to 3,000 hours/year
3. Space reorganization: Use micro-modular transformation to increase area utilization by more than 15%

13.3 Continuous supervision mechanism

Requires the establishment of a three-dimensional monitoring system:

• Real-time upload of energy consumption data to the municipal platform
• Monthly release of equipment failure rate analysis report
• Annual third-party energy efficiency audit
