ASHRAE releases datacom equipment power trends book

The second edition of ASHRAE's “Datacom Equipment Power Trends and Cooling Applications” is focused on helping planners, designers, and operators develop more affordable solutions.


Datacom technology has short product cycles and frequent equipment updates. In contrast, datacom facilities and their HVAC systems typically have long lifecycles. This mismatch of cycles means that a datacom facility’s design must be flexible enough to respond quickly to the changing needs of datacom equipment.

Based on the latest information from all the leading datacom equipment manufacturers, the newly published second edition of ASHRAE’s “Datacom Equipment Power Trends and Cooling Applications” provides new and expanded datacom equipment power trend charts to allow datacom facility designers to more accurately predict future datacom equipment loads of facilities and provides ways of applying the trend information to datacom facility designs today. Trends for individual components supplement the previous trend information, providing an understanding of the forces driving overall information technology equipment (ITE) power consumption.

“This second edition focuses on helping planners, designers and operators develop solutions that are more affordable today yet include provisions for future generations of IT equipment by providing valuable information on component and equipment trends as well as how to apply them,” said Don Beaty, chair of the Publications Subcommittee of ASHRAE’s technical committee (TC) 9.9, Mission Critical Facilities, Technology Spaces and Electronic Equipment, which wrote the book.

Chapters include an introduction, background, component power trends, load trends and their application, air cooling of equipment, liquid cooling of equipment, practical example of trends to data center design, and a valuable appendix that includes practical application examples.
