ASHRAE TC 9.9 Datacom Encyclopedia From the TC 9.9 Chair: I’m excited to release to you today the ASHRAE TC 9.9 Datacom Encyclopedia . The ASHRAE TC 9.9 Datacom Encyclopedia evolved in 2024 from the longstanding ASHRAE Datacom Series, a series of printed books that provides information on data center related subjects. The Datacom Encyclopedia offers updated, previously unpublished content formerly covered by the Datacom Series books Thermal Guidelines for Data Processing Environments , Design Considerations for Datacom Equipment Centers , and Liquid Cooling Guidelines for Datacom Equipment Centers , as well as PDFs of every edition of the 14 books in the ASHRAE Datacom Series for historical reference. Over time, the pertinent information from all the books will transition to be housed in this online encyclopedia. Subscribe today to access the ASHRAE TC 9.9 Datacom Encyclopedia. Access is granted via payment of an annual fee ($33 list price per year / $24 Member price per year). To enable and disable access to the encyclopedia, visit https://datacom.ashrae.org and click Manage Subscription in the top blue bar.

Updates Available on the TC 9.9 Datacom Encyclopedia Design Considerations for Datacom Equipment Centers The content previously covered in Design Considerations for Datacom Equipment Centers has been almost entirely rewritten to reflect the current trends in the data center industry. Every chapter has had major revisions. The content included on this site provides expanded and new information covering the following topics: Design criteria, HVAC loads, HVAC equipment, facility fluid distribution systems, air distribution, liquid cooling, ancillary spaces, contamination, acoustics, structural and seismic design, fire suppression, commissioning, availability and reliability, energy efficiency, and economizers. Liquid Cooling Guidelines for Datacom Equipment Centers The content previously covered in Liquid Cooling Guidelines for Datacom Equipment Centers has been almost entirely rewritten to include the most current industry thinking and consensus on the need for further guidance on liquid cooling. The content included on this site provides expanded and new information, including the following: 1. A discussion on the IT component power trends that are driving the need for liquid cooling to support the next generation of IT workloads. 2. Introduction of a new set of environmental classes (S Classes) for the supply temperature of the Technology Cooling System (TCS) coolant. 3. Expanded treatment of the differences in fluid quality requirements for the TCS and FWS loops. 4. Details on the design characteristics of conductive cold-plate and immersion cooling systems. 5. Design guidance is added for air-cooled facilities that are beingYou can find this bulletin here along with other TC 9.9 publications. Data Center and IT Equipment Design Guidance from ASHRAE TC 9.9 for Engineers, IT Professionals, and Facility Staff ASHRAE Technical Committee 9.9 will present design guidance for Engineers, IT Professionals and Facility Staff at a one day educational course in Lisbon on November 20, 2019. It is the first time ASHRAE’s full day design course has been presented in Europe. The new ASHRAE course explains how IT services that are lower cost, more energy efficient, provide more storage, and offer more computing capabilities impact operating conditions with a focus on ASHRAE’s evolving thermal guidelines for data processing environments. The course targets facility managers and IT professionals responsible for data center operation, executives and engineers who offer data center services to clients, suppliers and sales engineers whose equipment is used to cool data center spaces, and engineers who work on projects requiring ASHRAE TC 9.9 design specifications. More information and registration is available at: www.ashrae.org/ datacentertraining ASHRAE TC 9.9 Hard Disk Drive Performance Degradation Susceptibility to Acoustics White Paper This white paper serves to educate the data center community on the risks to hard disk drive (HDD) throughput performance from acoustics created by AMDs running at high speeds to adequately cool components within the racks. The methods used to optimize data center total cost of ownership (TCO) need to include these performance risks that can impact customer applications. ASHRAE TC 9.9 Water-Cooled Servers White Paper TC 9.9 has released a new white paper entitled " Water-Cooled Servers: Common Designs, Components, and Processes ." With more water-cooled IT products arriving in the marketplace, TC 9.9 felt the need to outline some of the common processes, parts, and materials for focus in use for future water-cooled designs. This white paper also corrects misunderstandings in the latest edition of Liquid Cooling Guidelines for Datacom Equipment Centers , and provides guidance for avoiding common mistakes based upon the book’s content. Much of the content in this white paper will be incorporated into a future third edition. ASHRAE TC 9.9 Liquid Cooling White Paper TC 9.9 has released a new white paper entitled " The Advancement of Liquid Cooling Solutions: The Perfect Storm Brewing " which addresses the growing trend of liquid cooling solutions in the data center. This brief is a window into a more comprehensive TC 9.9 white paper to be released later this year. ASHRAE TC 9.9 Overview Presentation As committed at the Orlando meeting, the overview presentation for TC 9.9 has been updated and is now available on this site. This overview can be used by members to understand what TC 9.9 does and the resources available from TC 9.9. Please consider this as ASHRAE’s material and always follow appropriate use considerations.
