Scope

This document provides guidance and recommendations for the application of liquid cooling to data centres.

This document addresses the following:

1) Architectural considerations;

2) Mechanical considerations;

3) Electrical considerations;

4) Communication considerations.

Purpose

This guidance aims to support the safe and reliable application of liquid cooling to data centres. This work item is proposed to address the following challenges:

• Heat generation from high-density IT equipment exceeding the capabilities of conventional air-cooling methods

• Increased thermal management requirements arising from the deployment of AI, cloud computing, and high-performance computing

• Diversity of liquid cooling technologies (e.g., direct-to-chip, rear-door heat exchangers, immersion cooling) requiring consistent design and operational practices

• Absence of standardized guidance leading to operational inconsistencies, risks, and safety concerns

• Industrial demands for unified recommendations on architectural, mechanical, electrical, and communication aspects to ensure reliable deployment
