Liquid Cooling Guidelines for Datacom Equipment Centers, 2nd ed. (ASHRAE Datacom Series Book 4)

Overview

This document is the fourth book of the ASHRAE TC 9.9 Datacom Series; the 2nd edition dates from 2013 and carries product code 90564. It is a paid publication, sold through the ASHRAE Bookstore or via a TC 9.9 Datacom Encyclopedia subscription. The book itself was not read here; only metadata from ASHRAE catalogue and Handbook descriptions was used.

According to the Handbook's description of the Datacom Series, the book covers liquid cooling definitions, the building of liquid loops inside the facility and the interface requirements between the chilled-water system and the technology cooling system. The subject is how chip- and rack-level liquid cooling meets the building-side cooling infrastructure. ASHRAE has also published an official errata PDF for the 2nd edition, and the URL in this record points to it.

The 2024 publications catalogue lists the book at $83 ($62 for ASHRAE members). Because the record does not describe the book's detailed content, technical numbers such as temperature classes or flow values are not included in this summary. Even so, the book's loop separation and naming logic matter because they give a shared vocabulary when building the data model of a liquid-cooled design.

Key points

Using it in design

• In the DLC data model, keep facility water (FWS) and technology cooling system (TCS) loops separate, with a CDU as the interface.
• Use this book as the reference for loop naming.
• In schematics, show clearly which side (building or IT) is responsible for each parameter at the interface points.

Who should read it

Mechanical engineers and system architects designing liquid-cooled data centers.
