Design Considerations for Datacom Equipment Centers, 2nd ed. (ASHRAE Datacom Series Book 3)

Overview

This book is Book 3 of the Datacom Series prepared by ASHRAE TC 9.9 (product code 90445). Its second edition dates from 2009 and runs to 222 pages. It covers the basic design of datacom centres and is regarded as one of the early reference sources for cooling design. This page rests on the ASHRAE catalogue and handbook descriptions rather than on the book itself.

The first part deals with design criteria: temperature, rate of temperature change, relative humidity, dew point and filtration. It also covers HVAC load, air and liquid cooling for the computer room, and air distribution. This gives a flow from the assumptions behind cooling design to the distribution solution.

Part II covers ancillary spaces and related topics: battery plants and generator rooms, contamination, acoustic noise, structural and seismic design, fire detection and suppression, commissioning, availability and redundancy. This scope shows that the book is not only a cooling guide but brings the building disciplines together.

As a limitation, the book dates from 2009, and recommended temperature ranges and cooling practices have since been updated through other ASHRAE publications.
