Recently, the American Society of Heating, Refrigerating and Air-Conditioning Engineers held its winter conference in Dallas, and SearchDataCenter.com was there to catch the data center angle. As you probably know, ASHRAE publishes books on cooling the data center; its most recent topic is liquid cooling.
In Dallas, liquid cooling continued to be a conversation topic, as were new studies on a new airflow measurement, air leakage, and raised floor vs. overhead cooling in high-density data centers. Check out the stories to find out what went down at ASHRAE Dallas.
ASHRAE Data Center Special Report:
Raised floor bests overhead cooling, IBM finds
Ditching your raised floor in favor of newer overhead cooling technologies might not be such a good idea, according to a study by two researchers at IBM.
More perforated tiles equal better data center cooling
A paper presented at last month's ASHRAE conference argues that raised floors leak more cold air when there are fewer perforated tiles.
APC 'capture index' measures airflow in the data center
Jim VanGilder, a principal engineer with American Power Conversion Corp.'s (APC) data center cooling simulation group, recently gave a presentation at the American Society of Heating, Refrigerating and Air-Conditioning Engineers' (ASHRAE) annual conference in Dallas regarding a new metric to measure airflow efficiency. We caught up with VanGilder to ask him what it's all about.
Liquid cooling is your friend, ASHRAE speakers say
Liquid cooling is nothing new to ASHRAE; its Technical Committee 9.9 published a book last month on the subject. In a recent interview about the liquid cooling book, committee member Don Beaty said that water is 3,500 times more effective at cooling than air.
