ASHRAE Publishes Updates on Liquid Cooling for Data Centers

April 11, 2014 By Linda Hardesty

ASHRAE Energy ManageASHRAE’s second edition “Liquid Cooling Guidelines for Datacom Equipment Centers” provides best practice guidance for implementing liquid cooling systems in data centers.

The book addresses increased interest in liquid cooled IT equipment at the rack, equipment and component levels as well as reuse of the heat rejected from IT equipment. The revised edition also includes the addition of supply water temperature classification.

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.

This week, 3M announced the implementation of a supercomputer developed in collaboration with Intel and SGI that uses a two-phase immersion cooling technology pioneered by 3M.

The Wall Street Journal reported that the higher temperature ranges and increased humidity levels set for data centers by ASHRAE have spawned innovative ideas for data center cooling.
