Executive Summary (Page 2)
"ASHRAE TC 9.9 created the first edition of the "Thermal Guidelines
for Data Processing Environments" in 2004." ...
.....
"TC 9.9 has recently published (May, 2011) a further update described
in a whitepaper available on TC 9.9’s website. The whitepaper
documents expanded data center environmental guidelines by adding
two more envelopes that are wider in temperature and humidity.
However, these guidelines are for air-cooled IT equipment and do not
address water temperatures provided by facilities for supporting liquid
cooled equipment here" ....
"This document describes classes for the temperature ranges of the
facility supply of water to liquid cooled IT equipment. In addition,
this document reinforces some of the information provided in the Liquid
Cooling Guidelines book on the interface between the IT equipment and
infrastructure in support of the liquid cooled IT equipment."
