Introduction

DEPARTMENT OF ENERGY –2020 REQUIREMENTS

SECTION 2

9

What is Changing? • Certain pump categories will be required

to meet energy conservation standards− Effective January 27, 2020


Less energy consumption

Department of Energy - 2020 Requirements

Why is this Changing? • The United States Government is pursuing

0.27 quadrillion BTUs of energy saving over a 30-year period − The most costly expense of a pump over time is

the energy costs− This new standard will reduce energy

consumption, saving your customers money!

• A new performance metric has been created− Pump Energy Index (PEI)

• PEI will have two classifications− Constant Load (PEICL)

− Variable Load (PEIVL)

Both classifications will be listed on the nameplate Both classifications will be listed on performance curve & literature

How will the New Requirement be Measured?

Pump energy index


17

PEI Definitions & Calculations• PEICL

− Pumps rated as bare pumps or pumps sold with motors

• PEIVL

− Pumps sold with motors and continuous or non-continuous controls rated


Great, but what is PER?

Department of Energy - 2020 Calculations

PEICL PERSTD

PERCL

PEIVL PERSTD

PERVL

18


• PERcl = the equally-weighted average electric input power to the pump measured (or calculated at the driver input over a specified load profile− Tested in accordance with DOE test procedure− Only applies to pumps in fixed speed equipment class − For bare pumps, default motor loss values for driver input calculations are specified in DOE

test procedure

• PERVL = the PER rating of a minimally compliant pump− Described as the allowable weighted average electric input power to the specfic pump − Metric applies to all equipment classes

• PERSTD = the equally-weighted average electric input power to the pump measured or calculated at the controller input over a specified load− Tested in accordance with the DOE test procedure − Metric only applies to pumps in a variable speed equipment class

Understanding Pump Energy Ratings - PER & PERSTD

Understand PER to find PEI


19

Understanding PERSTD

• A recent article by Pumps & Systems Magazine best describes how to find PER− Finding PER is needed to calculate PEI

• To establish baseline pump efficiency requirements:− 20 manufacturers submitted data on the five

pump types for over 3,000 unique pumps.– Flow

– Head

– Power

– Efficiency − DOE determined the baseline standards and life

cycle cost (LCC) analysis...– Resulted in what is called C-values

(Image 2) (Robinson, 2019)

20

Understanding PERSTD

• The baseline levels were taken at the 25th percentile (column EL 2) − All pumps below the 25th percentile will not be

in compliance with the standard

• When calculating both PEICL and PEIVL, those values shown in column EL 2 are to be used for PERSTD (Robinson, 2019)


25th Percentile


Image Source: https://www.pumpsandsystems.com/2020-pump-efficiency-doe-requirements


21


• ωi− 0.3333

• Piin,m

− Calculated driver power input to the motor at load point i for the minimally compliant pump (hp)

• i− The load point corresponding to 75, 100, or

110 percent of the BEP flow rate

Calculating PERSTD

Now we solve for PEI


22


• A value of PEI greater than 1.00 indicates: − Pump consumes more energy than allowed by DOE's energy conservation standard

− Pump does not comply

• A value less than 1.00 indicates:− Pump consumes less energy than the level required by the standard

− Pump does comply!

Solve for PEI

Department of Energy - 2020 Notes

• Is it possible to sell a pump to an end-user that has a pump label with a PEICL rating, but comes with a VFD?

− YES!

− If a motor and control are added to a PEICL rated pump, the PEICL can remain on the nameplate and no additional reporting to DOE is required

Frequently Asked Questions

PELCL can remain on nameplate when system changes occur


24


• How will the DOE enforce these requirements? Are there inspectors required at every installation? What local jurisdiction will be handling compliance of the DOE regulation?

− DOE enforces the standards

− DOE’s assessment and enforcement process is documented in 10 CFR 429 – subpart C

− Additional Information: http://energy.gov/gc/conservation-standards-enforcement-useful-links


US DOE will enforce the standards


http://energy.gov/gc/conservation-standards-enforcement-useful-links

25


• Is the PEI rating only conducted on full diameter impellers, or can a pump be rated with a trimmed impeller?

− PEI is determined based on the full impeller diameter of the rated basic model.

Subsequent trimmed impellers can be distributed in commerce under the same rated basic model number

The manufacturer has the option to trim the impeller and re-designate the trimmed impeller as the full diameter as a new basic model


Trimmed impellers are covered by full impeller model numbers

PUMP SELECTIONSSECTION 3

28

Pump Selections

• Manufacturers can only sell regulated pumps that are in compliance with DOE for the pump types and applications discussed

− Pump selection post regulation will be very similar to making a pump selection today

− Burden is on the manufacturer to provide DOE-compliant pumps

− Selection software programs and efficiency curves are best pump selection tools

Starting on January 27, 2020...

How should I select pumps?

Pump Selections

• To make energy efficient selections, utilize sizing programs like the Pentair Encompass tool to:

− Find best efficiency points

− Find solutions that allow Max HP to align with the Rated HP requirements

This will allow you to select more efficient motors!

Sizing Programs - Encompass

Encompass quickly provides BEP & HP requirements!


EXAMPLE• Pentair Aurora*

End Suction 3800 Series Pump

• 200 gpm

• 70 Feet

30

Pump Selections

• Pentair Aurora* End Suction 3800 Series Pump

− Review & select best Pump Efficiency


Next step, reviewing the curve...


31

Pump Selections

• Pentair Aurora* End Suction 3800 Series Pump − Use the curve to ensure you have the lowest motor HP

Rated power is when the HP is acceptable at the duty condition, but will not support the pump as you get closer to runout

Max power is when the motor HP can meet conditions at runout In this example, you would not need to increase the motor HP to meet runout conditions.

This will save money, and energy costs


Motor HP considerations
