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

Remember the Objective 01/08/2015 Frank Ennenbach, Sulzer Pumps Chairman Europump Standards Commission 2 Save Energy – Selection of properly sized pump – Optimum combination of components – System feedback

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 01/08/2015 Frank Ennenbach, Sulzer Pumps Chairman Europump Standards Commission 3

What is wanted by EU? 01/08/2015 Frank Ennenbach, Sulzer Pumps Chairman Europump Standards Commission 4 Quantification of Energy Savings Intrinsic product property / scale / index Energy evaluation / comparison of products – mandatory thresholds – Labeling/marking

EuP Water Pumps Regulation - draft 01/08/2015 Frank Ennenbach, Sulzer Pumps Chairman Europump Standards Commission 5 Chapter 1 Subject 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. 2. 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.

EuP Water Pumps Regulation - draft 01/08/2015 Frank Ennenbach, Sulzer Pumps Chairman Europump Standards Commission 6 ANNEX II Ecodesign 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.

Future EU Approach Pumps – Extended Product Approach – Legislation Draft: Article 7 Revision 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. ……. 01/08/2015 Frank Ennenbach, Sulzer Pumps Chairman Europump Standards Commission 7

Definitions 01/08/2015 Frank Ennenbach, Sulzer Pumps Chairman Europump Standards Commission 14 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

Methodology for EEI 01/08/2015 Frank Ennenbach, Sulzer Pumps Chairman Europump Standards Commission 15 The proposed methodology to determine EEI of pump units will comprise two alternative ways: 1.test of the complete pump unit 2.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

Semi-Analytical Model of pumps 01/08/2015 Frank Ennenbach, Sulzer Pumps Chairman Europump Standards Commission 16 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)

What we need on standardization for PDS 01/08/2015 Frank Ennenbach, Sulzer Pumps Chairman Europump Standards Commission 21 Standard(s) should describe test method(s) for related PDS losses including information on tolerances / allowable uncertainties Standard(s) should specify supporting points within related 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
