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

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

4
What is wanted by EU?

• Quantification of Energy Savings
• Intrinsic product property / scale / index
• Energy evaluation / comparison of products
• mandatory thresholds
• Labeling/marking

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
  -10C 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
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.

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. .

Working Group

• Pump Manufactures - EUROPUMP
• Motor Manufacturers
• Drive Manufacturers
• CEN CENELEC
• Scientific support by Technical University of
  Darmstadt

13
What is needed ?

• Load Profile Definition
• Generalized but realistic
• Reference Definition (Base Case)
• Market Figures

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

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

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)

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

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
