Stulz mission energy

  1. 1. STULZ IT Cooling Solutions and Services 11 Mission Energy: Energy Efficient Cooling Developing CAPEX efficient free cooling strategies and evaluating their impact on OPEX and TCO
  2. 2. STULZ IT Cooling Solutions and Services 22 The tasks of cooling a data centre What is a direct and an indirect free cooling system? TCO calculations for your investment in the future The air conditioning systems of the future STULZ – your partner for coolnig solutions The new dimension of free cooling !
  3. 3. STULZ IT Cooling Solutions and Services 33 The tasks of cooling a data centre The new dimension of free cooling !
  4. 4. STULZ IT Cooling Solutions and Services 4 Goals today: Cold aisle – hot aisle concept, but…  seperate the cold and the hot air
  5. 5. STULZ IT Cooling Solutions and Services 5 …„straight rows of racks are mixing with „other“ IT equipment
  6. 6. STULZ IT Cooling Solutions and Services 6 The target of the air conditioning: cold air in front of the 19” level  and a clear horizontal air path through the rack Source: INTEL Source: HP
  7. 7. STULZ IT Cooling Solutions and Services 77 Energy flow through the Data Centre Power Usage Efficiency Finally all leaves as Waste Heat Source: The Green Grid
  8. 8. STULZ IT Cooling Solutions and Services 8 FREE COOLING Room conditions Ambient air Raised floor height Water temperatures Part load behaviour Coil dimensioning Filter surface Fan technology Unit sizing Refrigerant Pipework dimensions Pump technology Unit options parameters Filter condition Amount of refrigerant Air path Some criteria that have an influence on the energy efficiancy of your data centre Stand-by concept setpoints Sensor adjustment
  9. 9. STULZ IT Cooling Solutions and Services 99 What is a direct and an indirect free cooling system? The new dimension of free cooling !
  10. 10. STULZ IT Cooling Solutions and Services 10 …free cooling is not a new technology - at least not in this region! Indirect free cooling indirect: water/glycol will be used as a medium between the inside and outside Direct free cooling direcf: a huge part of the ambient air will be delivered inside the data centre Cooling the room without compressor operation: FREE COOLING Free cooling for IT-rooms
  11. 11. STULZ IT Cooling Solutions and Services 11 Indirect free cooling indirect: water/glycol will be used as a medium between the inside and outside Direct free cooling direcf: a huge part of the ambient air will be delivered inside the data centre Cooling the room without compressor operation: FREE COOLING Free cooling for IT-rooms ⇒ pedal conneted to the back wheel with a chain will be used for the transmission of force ⇒ pedal directly at the wheel
  12. 12. STULZ IT Cooling Solutions and Services 12 Function of the indirect free cooling system
  13. 13. STULZ IT Cooling Solutions and Services 13 Indirect free cooling CRAC units with integrated free cooling function Room air will be seperated from the ambient air by a water/glycol system
  14. 14. STULZ IT Cooling Solutions and Services 14 Indirect free cooling chillers with integrsted free cooling function Room air will be seperated from the ambient air by a water/glycol system
  15. 15. STULZ IT Cooling Solutions and Services 1515 TCO calculations for your investment in the future The new dimension of free cooling !
  16. 16. STULZ IT Cooling Solutions and Services 16 System without freecooling vs. System with free cooling TCO calculation for future investments
  17. 17. STULZ IT Cooling Solutions and Services 1717 CAPEX +32% OPEX -56% PER YEAR Example1: Traditional Air cooled vs. Stulz DFC
  18. 18. STULZ IT Cooling Solutions and Services 1818 Example1: Traditional Air-cooled vs. Stulz DFC € 220.000.- Cost reduction
  19. 19. STULZ IT Cooling Solutions and Services 1919 Example1: Traditional Air-cooled vs. Stulz DFC
  20. 20. STULZ IT Cooling Solutions and Services 2020 Example 2: Chilled Water vs. DFC (300kW) CAPEX: +70% OPEX: -60% 10 year Savings= €570.000
  21. 21. STULZ IT Cooling Solutions and Services 2121 Example 2 : Chilled Water vs. DFC (300kW)
  22. 22. STULZ IT Cooling Solutions and Services 22 Energy use DX Compressor operation FC Freecooling EFC Extended Freecooling MIX Compressorand Freecooling Indoor Outdoor Control data Dynamic Free Cooling, Control of all components In the system to assure The minimum power consumption Further potential of saving energy with an indirect free cooling system  variable control of all components  Stand-by management  Maximum energy eficiancy  approx. 30% energy saving against Other free cooling systems
  23. 23. STULZ IT Cooling Solutions and Services 2323 The air conditioning systems of the future The new dimension of free cooling !
  24. 24. STULZ IT Cooling Solutions and Services 24 NEW CONCEPTS: STULZ Direct Free Coolung! ASHRAE TC 9.9 - 2004 ASHRAE TC 9.9 - 2008 Different requirements allow f or new concepts! or Tight tolerances will still require Indirect free cooling systems!
  25. 25. STULZ IT Cooling Solutions and Services 25 NEW CONCEPTS: STULZ Direct Free Cooling! Berlin Bremerhaven Essen Frankfurt Hamburg Mannheim München Nürnberg Stuttgart % Anteil 87,6 94,1 91,2 86,8 92,6 85,7 90,0 88,9 90,7 Stunden 7.672 8.239 7.992 7.601 8.111 7.508 7.883 7.787 7.942 Stunden = Jahrestemperaturstunden bis einschließlich 18°C WETTERDATEN Mittlere jährliche Stundenanzahl, gemäß DIN 4710 Januar 2003 % Anteil = Prozentualer Anteil der Jahrestemperaturstunden bis einschließlich 18°C In Germany for example more the 85% of the time the temperatures are ≤ 18°C Here the results will be even BETTER!!!!
  26. 26. STULZ IT Cooling Solutions and Services 26 NEW CONCEPTS: STULZ Direct Free Cooling with optimised coil placement
  27. 27. STULZ IT Cooling Solutions and Services 27 NEW CONCEPTS: STULZ Direct Free Cooling! Advantages:  High energy efficiancy by using direct free cooling technology – no losses by additional heat exchangers  High scalibility of the system „Build as you grow!“ – no hydraulics (pipework, pumps, valves) at day 1 needed for the final stage  Lower CAPEX compared with indirect free cooling systems  Lower OPEX (energy consumption) the on all other systems
  28. 28. STULZ IT Cooling Solutions and Services 28 NEW CONCEPTS: STULZ Direct Free Cooling! Conditions:  Accepted room humidity level at approx. 20%- 80% r.H.  Ambient conditions need to be observed (dust) while selecting the site (not close to highways, harvest or in the city centres)  Acceptance of possible ourside influences (e. g. smoke, gas, etc.)  Compromising the building safety Structural conditions:  Free in the construction of the building  short distances of the air intake and extract (pressure losses)  Air intake on the shadow side of the building
