  1. Europump's Pump Efficiency Program HI Annual Meeting 2012St. Petersburg, Fl

  2. Remember the Objective • Save Energy • Selection of properly sized pump • Optimum combination of components • System feedback Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  3. Current EU Approach • Water Pumps • Focus on product • Pump only without drive or VFD • Legislation in Parliament • Expected European Official Journal Summer 2012 • Heating Circulators • Focus on Pump, Motor, VFD and Controls • Regulation in place Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  4. What is wanted by EU? • Quantification of Energy Savings • Intrinsic product property / scale / index • Energy evaluation / comparison of products • mandatory thresholds • Labeling/marking Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  5. EuP Water Pumps Regulation - draft • Chapter 1Subject matter and scope • 1. This Regulation establishes ecodesign requirements for the placing on the market of rotodynamic water pumps for clean water duty, including where integrated in other products. • This Regulation shall not apply to: • (a) water pumps designed specifically for pumping of clean water with temperatures below -10°C or above 120 °C, except as regard to the information requirements of Annex II, point 2(11) to 2(15); • (b) water pumps designed only for fire-fighting applications; • (c) displacement water pumps; • (d) self-priming water pumps. Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  6. EuP Water Pumps Regulation - draft ANNEX IIEcodesign requirements for water pumps 1. efficiency requirements (A) From 1 January 2013, water pumps shall have a minimum efficiency index of MEI ≥ 0.10, when measured according to Annex III. (B) From 1 January 2015, water pumps shall have a minimum efficiency index of MEI ≥ 0.40, when measured according to Annex III. Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  7. Future EU Approach • Pumps • Extended Product Approach • Legislation Draft: Article 7Revision The Commission shall review this Regulation in the light of technological progress and shall present the result of this review to the Consultation Forum no later than four years after its entry into force. The review shall aim at adopting an extended product approach. ……. Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  10. Electric Motor ExtendedProduct Approach = Motor Driven System Mains System Feedback VSD, Control, Monitoring Fluid Outlet Spiral Casing with Impeller Fluid Inlet Coupling Base Plate Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  11. Electric Motor Extended Product Approach ? VSD, Control, Monitoring index Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  12. Working Group • Pump Manufactures - EUROPUMP • Motor Manufacturers • Drive Manufacturers • CEN & CENELEC • Scientific support by Technical University of Darmstadt Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  13. What is needed ? • Load Profile Definition • Generalized but realistic • Reference Definition (Base Case) • Market Figures Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  14. Definitions • Within EUROPUMP, a methodology and a draft standard will be developed for the determination of energy efficiency of pump units • Pump units consisting of pump + power drive system (PDS) are defined as Extended Products • EEI (Energy Efficiency Index) proposed to quantify energy efficiency of pump units • Activities concerning energy efficiency of pump units are called EPA (Extended Product Approach) • Mandate in draft legislation of Water Pumps and new EU ErP work items Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  15. Methodology for EEI • The proposed methodology to determine EEI of pump units will comprise two alternative ways: • test of the complete pump unit • calculations based on so-called Semi-Analytical Models (SAMs)(normally done by the end-supplier of the complete pump unit) • For application of the 2nd method, two SAMs are needed • SAM of pumps • SAM of Power Drive Systems • Semi-Analytical Model = mathematical description of component characteristics which only needs limited test data as input to adapt the model to the real component Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  16. Semi-Analytical Model of pumps • SAM of pumps is based on hydrodynamic fundamentals and is adjusted by test data at 3 specified flow rates • These test data can directly be taken from former tests by the pump manufacturer already mandatory to quantify the energy efficiency of the pump itself (EuP) • SAM of pumps delivers rotational speed n and shaft torque T for pump operating conditions (specified by defined load profiles and pressure control curves) Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  17. Scheme of determination EEI Input Software Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  18. PDS rated torque / % P P P V PDS (0;100) V PDS (50; 100) V PDS (100; 100) 100 P P P V PDS (0; 50) V PDS (50; 50) V PDS (100; 50) 50 P P V PDS (0; 25) V PDS (50, 25) 25 PDS rated speed / % 50 100 PDS Loss/Efficiency Points CLC TC 22x WG6 Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  19. PDS rated torque / % P P P V PDS (0;100) V PDS (50; 100) V PDS (100; 100) 100 P P P V PDS (0; 50) V PDS (50; 50) V PDS (100; 50) 50 P P V PDS (0; 25) V PDS (50, 25) 25 PDS rated speed / % 50 100 Pump Load driven by PDS Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  20. What exists ? • EEI Energy Efficiency Index for Circulators • EEI for Pumps under preparation • PDS Classes under preparation • Market figures for Europe • Efficiency Standard for pumps • Legislative mandates to work on EEI Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  21. What we need on standardization for PDS • Standard(s) should describe test method(s) for related PDS losses including information on tolerances / allowable uncertainties • Standard(s) should specify supporting points withinrelated PDS losses = f(T,n)-map suitable for an interpolation scheme valid within the range of „EEI pump operating points“ • Standard(s) should clarify the responsibilities and the procedures to determine and indicate related PDS losses by motor/frequency inverter manufacturers Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  22. EuP - New Work Items ENER Lot 28:             Pumps (extended product approach including motors, VSD and controls, where appropriate) for private and public waste water (including all stages including buildings, networks and treatment facilities) and for fluids with high solids content ENER Lot 29: Pumps (extended product approach including motors, VSD and controls, where appropriate) for private and public swimming pools, ponds, fountains and aquariums, as well as clean water pumps larger than those regulated under Lot 11 Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission

  23. Ecodesign Directive 2009/125/EC • Draft Working Plan (2012-2014): issued by DG ENTR bef. Xmas 2011 - Comments by 08.02.2012 finalised by mid-April 2012 • Windows • Steam boilers (< 50MW)                            • Power cables • Enterprises servers, storage and ancillary equipment • Smart appliances/meters • Positive displacement pumps (depending on lots 28-31) • Fractional horse power motors under 200W (depending on lots 28-31) • Heating controls • Lighting controls  Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission
