Seminar 71 -- The Continuing Evolution of the ASHRAE Data Center Environmental Guidelines

This product is a zip file that contains files that consist of PowerPoint slides synchronized with the audio-recording of the speaker, PDF files of the slides, and audio only (mp3 format) as noted.

To address the growing emphasis on energy efficiency of data centers, TC 9.9 has been evolving the Thermal Guidelines on a regular basis as data becomes available. A historical perspective is given including the latest change to the recommended envelope based on research of high humidity and gaseous pollutants as it affects the reliability of IT equipment. Another environmental envelope has been added to the existing 4 air-cooling classes to accommodate high density racks. With increasing high density racks the IT industry will be deploying more liquid cooling products. With these trends the water-cooling classes have been expanded and renamed.
