Data Center Cooling Efficiency, Optimization and Trade-offs

Learn how to lower Cooling costs 30-80% while increasing sustainability.

Gain insight on advantages and the trade-offs of the many technologies, where combinations of technologies may be best, and learn how cooling solutions play into the upcoming Title 24 Code changes.

From Best Practices, Containment (Hot vs. Cold, Passive vs. Managed, Chimney’s and IT Rows), Demand Based Cooling (Managed Distribution), new High Efficiency In Row Cooling (close coupled) technologies (CMS designs = 40% - 60% more efficient), new High Efficiency CRAC/H’s (CMS designs = 40-50% more efficient).

  1. 1. Data Center Cooling Efficiency, Optimization, and Trade-offs<br />Presented by<br />Teladata<br />Sponsored by<br />CAPS<br />
  2. 2. Greg Stover, NER Data Corporation<br />Senior Vice President<br />“Cooling Efficiency Enthusiast”<br />
  3. 3. Greg Stover, NER Data Corporation<br />a focus on<br />Infrastructure Optimization Solutions<br />For data center cooling, and monitoring efficiency! <br />
  4. 4. Best in Class Partners<br />
  5. 5. Energy Efficiency Is Important<br />
  6. 6. Data and Title 24<br />What Does It Mean?<br />The California Investor Owned Utilities (IOUs) are actively supporting the California Energy Commission (CEC) in developing the state’s building energy efficiency code (Title 24)<br />Their joint intent is to achieve significant energy savings through the development of reasonable, responsible, and cost-effective code change proposals for the 2011 code update and beyond. To go into effect January 1, 2013<br />As part of the IOU effort, at the request of the CEC, they have been hosting stakeholder meetings to get industry input and feedback on the code change proposals<br />
  7. 7. Data Centers and Title 24<br />Some Things to Expect:<br />VAV/VFD’s on CRAC/H’s - will likely be a requirement<br />Containment - Separation of Hot and Cold air streams will likely be a requirement – No position being taken on Hot vs. Cold<br />Economization–Utilization of “free cooling” will be required (water or airside)<br />Require Adiabatic humidification- (evaporative or ultra sonic)<br />Performance Methods - always an option!<br />These will likely become new code<br />
  8. 8. Data Centers and Title 24<br />Containment examples sited at stakeholders meeting included:<br />Cold Aisle top caps & end caps - (Both raised floor and overhead delivery)<br />Hot Aisle vertical partitions - (using ceiling plenum as a return)<br />Hot Aisle containment with row based/close coupled cooling - (CMS-APC-Liebert)<br />In rack liquid cooling - Like the Rittal design<br />Combined Hot & Cold Aisle - (closed loop) – Cold air flows thru bottom of cabinet, to chimney/ceiling return like the Verari design.<br />Heat Containment Chimneys - Both passive and pressure managedProviding direct plenum exhaust return path.<br />
  9. 9. Data Centers and Title 24<br />Containment examples sited at stakeholders meeting included:<br />Packaged and/or custom Hot Aisle containment – Like Wrightline’sdesign and other custom heat containment rooms.<br />In rack liquid Cooling –Like Knurr design<br />Rear door Heat Exchanger – Like Vette/Cool Centric and future CMS designs<br />Liquid Cooling “Clustered Systems” -This complies as it is liquid cooled, not fan cooled<br />
  10. 10. The Basics - Simplify<br />Get cold air where it needs to be, when it needs to be there, in just the right amount<br />Removing heat before it can mix/or cause hot spots<br />
  11. 11. The Basics - Simplify<br />4 keys to cooling efficiency success<br />Cooling side - Supply efficiency<br />Airflow/supply - Delivery efficiency<br />Heat/exhaust side - removal efficiency<br />Supply temp to Inlet temp delta - Narrowing that delta<br />
  12. 12. How You Save Money<br />Mechanisms to realize cooling efficiency<br />Reduce or eliminate oversupply<br />Safely raise supply air temperatures<br />Safely raise chilled water temperatures<br />Increase economization utilization<br />
