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.
