  • 10. ASHRAE 90.1 Climate Zone Economizer Requirement Map No requirement Data Centers >19kW Data Centers >40kW Schneider Electric Basically, if you’re blue, economizer use is mandated! 10
  • 11. Paradigm Shift: Economizer to Become PRIMARY Mode of Operation Reduce/eliminate the use of a compressor system and move toward a highly efficient Data Center Cooling system OLD: Use economizer as a supplemental mode Schneider Electric NEW: Use economizer as the primary mode 11
  • 12. Agenda  Top 3 NAM trends for Data Center Cooling today  Economizers – types & options  High Performance Cooling – Where is the industry heading?  Selecting the right Cooling solution for your Data Center  Summary Schneider Electric 12
  • 13. An Overview of the Economizer Mode Operating in economizer mode saves energy Schneider Electric It is often a requirement to meet efficiency targets “Economizer is a mode of operation, not an object” 13
  • 14. Purpose and Function of Economizer Modes The system must do less work to cool the data center • Cooling systems’ efficiency have improved For greater efficiency gains Schneider Electric Bypass compressor • The development of economizer modes 14
  • 15. Factors that Impact Economizer Mode Operation  Geographic location  Cooling system set points  Separation of hot and cold air streams Schneider Electric 15
  • 16. Impact of Geography / Ambient Schneider Electric 16
  • 17. Impact of Cooling Set Points ASHRAE TC9.9 ● ASHRAE (Technical Committee)9.9 sets the recommended operating limits within the data center. 2008 Limits Temp Range: 64.4-80.6°F Humidity Range: (DP 42°F) – (60% RH & DP 59°F) ● In 2008, the limits were widened to allow for raised rack inlets temperatures. ● This widened envelope allows for efficiency and energy savings through more hours of economization 2004 Limits Temp Range: 68-77°F Humidity Range: 40-55% Schneider Electric 17
  • 18. Impact of Containment Facilitates higher supply & return air temperatures COLD-aisle containment HOT-aisle containment HOT air free in the room Cold aisle COLD air free in the room Hot aisle The key benefit of both methods comes from SEPARATION of cold supply air from hot return air Schneider Electric 18
  • 19. Comparison of Economizer Modes 15 Economizer Types or Modes!! Let’s focus in on ‘the top 3’ Schneider Electric 19
  • 20. Good - A/C bypass using Direct Fresh Air Key Components  Fans and Louvers o Draw cold outside air through filters into the data center  Louvers and Dampers o Control the hot exhaust air released to the outdoors and back into the data center air supply  Filters o Filter the supply air Evaporative assist can be used in this type of economizer mode Warning: Mixing of outside & inside air can result in particulate contamination Schneider Electric 20
  • 21. Better - A/C Bypass via Heat Wheel Key Components Fans o Blows cold outside air through a rotating heat exchanger o Separate fans blow heated exhaust air across the same heat exchanger Heat Wheel o Rotating heat exchanger o Isolates outside air from data center air o 100% sensible cooling Evaporative assist can be used in this type of economizer mode Schneider Electric 21
  • 22. Best - A/C Bypass using Air Heat Exchanger a.k.a. Indirect Evaporative Cooling Key Components Fans o Blows cold outside air over a heat exchanger o Separate fans blow heated exhaust air across the same heat exchanger Air-to-air Heat Exchanger o Cools hot data center air and isolates the air from the outside air o Eliminates the need for pretreatment & filtration o 100% sensible cooling Evaporative assist can be used in this type of economizer mode Schneider Electric 22

  • 26. New Challenge: Dynamic Power Variation Past Future IT load power varies less than 5% with computational load IT load varies +5% in proportion to computational load Power and cooling accommodation of IT load changes is manual Power and cooling automatically adapt based on IT load changes Both total and individual IT airflow requirements are constant Total IT airflow changes over time and moves around the data center Problems like hot spots and overloads are static and can be measured and modeled with CFD There is no single state to be modeled. Performance must be predictable. To deal with dynamic power variation, use of past design approaches requires gross over provisioning Schneider Electric Foundational BUSINESS OVERVIEW Rev 1 26
  • 27. Is Liquid Cooling the Answer? Promise: • Widespread use of liquid-air & liquidliquid HX in gaming PCs, consoles, etc. • Entry cost is decreasing • New refrigerants are opening gateways to the re-application of submersion technologies Challenge: • Implementation is OEM-driven or requires modification of IT gear that is substantial • Entry cost is still far higher than aircooling • ROI is too long for widespread adoption beyond niche HPC applications • Some technologies not ‘market ready’ Schneider Electric 27
  • 28. ‘New’ Cooling Technologies: Technology Summary of our view Fresh air cooling Extremely high efficiency in some climates. Climatelimited application due to humidity issues, and with danger of particulate contamination to IT gear. Indirect Air-Air heat exchanger cooling Very high efficiency. Can be used in almost any climate. A general replacement for traditional cooling systems Thermal storage (water tanks, phase change) Cost effective for cases with high swings in time of day pricing or where value of demand management is high. Increase in effectiveness of economizers will make this a niche application Liquid cooled IT Becomes practical as cabinet power passes 20kW. Suitable only for highly homogeneous IT installations. May become even more common for HPC installations. Cooling remains an opportunity for significant energy and water reductions Schneider Electric 28 Foundational BUSINESS OVERVIEW Rev 1
  • 29. Update: Established Technologies Technology Summary of my view Perimeter Cooling – CRAH/CRAC (evolving) In use for decades, but technology languished. Now updated through use of high efficiency EC fans, EEVs, higher efficiency compressors and high SHR designs. Less use of energy-hogging humidification & reheat. InRow Cooling (evolving) Now available in multiple forms of heat rejection. Proven for use in mid to high density applications. New economizer solutions. ROI of 3 years or less is common (vs. legacy CRAC/CRAH) Containment (adoption) Rapid expansion in the market. A necessity where optimized use of Economizers is desired. CACS gaining popularity in existing Data Centers. HACS popular in new-build, hybrid and Row-based Cooling applications. Modular Data Centers (acceptance) Effective for all applications – now evolving beyond “IT Containers”. Expect widespread use in the future. Combinations of these approaches are how data centers will improve in the future Schneider Electric 29
