Provides updated liquid cooling guidelines for data centres
Saying that data centre rack heat loads are steadily climbing, creating a need for liquid cooling solutions to reduce the volume of airflow needed, as well as lower processor temperatures for better computer performance, ASHRAE has introduced “Liquid Cooling Guidelines for Datacom Equipment Centers”. The recently published second edition also provides best practice guidance for implementing liquid cooling systems in data centres, ASHRAE added.
ASHRAE gave further details:
“There is an increasing interest in liquid cooled IT equipment at the rack, equipment and component levels,” Don Beaty, Publication Chair of Technical Committee 9.9., Mission Critical Facilities, Data Centers, Technology Spaces and Electronic Equipment, said. “There is also increased interest in reuse of the heat rejected from IT equipment. One of the more important changes to the second edition is the addition of supply water temperature classification.”
Beaty claimed that the addition of liquid classes can have a similar effect on the industry as the creation of supply air temperature classes did, which was the critical enabler to the use of economisers in data centres.
“There are five water temperature classes with the highest temperature class being >45 C (113 F), which opens up possibilities for using the rejected heat for building heating systems,” he explained.
ASHRAE gave purchasing details: The cost of “Liquid Cooling Guidelines for Datacom Equipment Centers,” second edition, is $54 ($46 ASHRAE members).
