  1. EUROPUMPLOT11 - Consultation ForumContribution

  2. Minimum EEI values Circulators Example:htot. = 0.92 · 0.96 · 0.730 = 0.645EEI  0,3 for big circulators h tot. = hMotor·h elec.·hhydr.

  3. Circulators • A-G Class labelling  mandatory (2010) • Introduction of new voluntary labelling class A* (EEI < 0.3) • Make A the minimum efficiency performance (MEP) in 2015 (150Mio €)

  4. Technical feasibility of A* and A** 64,5%

  5. BAT-Circulators with PM-motor in market today A A* A** ~25 ~250 Technical feasibility of A* and A** Technical borders for different circulator sizes based on catalog data and BAT efficiency curve assumption Best possible Label class PHyd > 250 W Best possible Label class 25 W < PHyd < 250 W Best possible Label class PHyd < 25 W

  7. Water Pumps • Focus changed from Application to pump type • Methodology (TU Darmstadt) with part- and overload evaluation (House of Efficiency) • CE-Assessment Standard to be developed • ‘Best in Class’ Labelling leads to wrong pump selection (Problem: Duty Point – BEP) • Effort compared to savings too high for proposed cut-off • Costs appr. 226 Mio € for CutOff 30%

  8. Water Pumps – BiC Labelling Final AEA-Report 2008

  9. What is Cut Off ?

  10. What is Cut-Off [%] ? Cut-Off 5%

  11. What is Cut-Off [%] ? Cut-Off 20%

  12. What is Cut-Off [%] ? Cut-Off 40%

  13. What is Cut-Off [%] ? Cut-Off 60%

  14. What is Cut-Off [%] ? Cut-Off 80%

  15. Additional Development Costs • DC = f1· f2 · f3 · Zcut · fd · 200 000 € • f1 = not included manufacturers in data collection • f2 = not included models • f3 = modular complexity reduction • Zcut = pumps to be improved in market • fd = density harmonisation, etc. / additional product range
