Pumps - Rotodynamic Pumps - Energy efficiency Index - Methods of qualification and verification - Part 3: Testing and calculation of energy efficiency index (EEI) of booster sets

The proposed Part 3 of the Standard on energy efficiency index (EEI) of pump units focusses on booster sets.
Part 3 will give special definitions  (e.g. a reference flow-time profile, a reference pressure control and - in the case of multipump booster sets - a reference switching control and a reference electric power input) that have to be applied when determining their energy efficiency index (EEI).
It will describe two methods and procedures how to determine the energy efficiency index (EEI) of booster sets in the frame of qualification or verification.

Introduction
This part of the European Standard is the third part of a series of standards describing a methodology to
evaluate energy efficiency performance of booster sets, comprising one or more pump(s), the motor(s)
with or without frequency converter, and additional components influencing hydraulic performance. It
is based on a non-dimensional numerical value called Energy Efficiency Index (EEI). An EEI allows the
comparison of different configurations with one common indicator. Physical influences such as number
and size of the incorporated pump(s), pump unit part-load operation, motor-efficiency characteristic
and frequency converter influence are implemented into this metric.
Specific requirements for testing and a calculation method for EEI, the so called semi-analytical model
(SAM) of a complete booster set, a specific flow-time profile and a reference control curve are given in
this part of the standard.
EEI is an index to rate booster sets according to their energy efficiency but does not replace the need to
do a life-time cost analysis regarding energy consumption over the life time of the booster set.

1 Scope
This documents specifies methods and procedures for testing, calculating and determining the Energy
Efficiency Index (EEI) of booster sets.
A booster set is either a single pump unit or an assembly of pump units connected in parallel with a
3 3
maximum hydraulic power of 150 kW, a minimum rated flow of 6 m /h (0,001667 m /s), to be operat-
ed with backflow prevention and additional components influencing hydraulic performance and with
components necessary to control pressure or provide flow in open loops inside buildings and which is
placed on the market and/or put into service as one single product and its intended use is to pump
clean water and does not have a self-priming functionality.
