Energy Conservation Program for Consumer Products: Publication of
the Petition for Waiver and Notice of Granting the Application for
Interim Waiver of Electrolux From the Department of Energy Residential
Refrigerator and Refrigerator-Freezer Test Procedure
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Notice of Petition for Waiver, Notice of Granting Application
for Interim Waiver, and Request for Public Comments.
-----------------------------------------------------------------------
SUMMARY: This notice announces receipt of and publishes the Electrolux
Home Products, Inc. (Electrolux) petition for waiver (hereafter,
``petition'') from specified portions of the U.S. Department of Energy
(DOE) test procedure for determining the energy consumption of electric
refrigerators and refrigerator-freezers. The waiver request pertains to
Electrolux's product
[[Page 76963]]
lines that utilize a control logic that changes the wattage of the
anti-sweat heaters based upon the ambient relative humidity conditions
to prevent condensation. The existing test procedure does not take
humidity or adaptive control technology into account. Therefore,
Electrolux has suggested an alternate test procedure that takes
adaptive control technology into account when measuring energy
consumption. DOE solicits comments, data, and information concerning
Electrolux's petition and the suggested alternate test procedure. DOE
also publishes notice of the grant of an interim waiver to Electrolux.
DATES: DOE will accept comments, data, and information with respect to
the Electrolux Petition until, but no later than January 10, 2011.

SUPPLEMENTARY INFORMATION:
I. Background and Authority
Title III, Part B of the Energy Policy and Conservation Act of 1975
(``EPCA''), Public Law 94-163 (42 U.S.C. 6291-6309, as codified),
established the Energy Conservation Program for ``Consumer Products
Other Than Automobiles,'' a program covering most major household
appliances, which includes the refrigerator-freezers that are the focus
of this notice.\1\ Part B includes definitions, test procedures,
labeling provisions, energy conservation standards, and the authority
to require information and reports from manufacturers. Further, Part B
authorizes the Secretary of Energy to prescribe test procedures that
are reasonably designed to produce results which measure energy
efficiency, energy use, or estimated operating costs, and that are not
unduly burdensome to conduct. (42 U.S.C. 6293(b)(3)) The test procedure
for residential refrigerators and refrigerator-freezers is contained in
10 CFR part 430, subpart B, appendix A1.
---------------------------------------------------------------------------
\1\ For editorial reasons, upon codification in the U.S. Code,
Part B was re-designated Part A.
---------------------------------------------------------------------------
The regulations set forth in 10 CFR 430.27 contain provisions that
enable a person to seek a waiver from the test procedure requirements
for covered consumer products. A waiver will be granted by the
Assistant Secretary for Energy Efficiency and Renewable Energy (the
Assistant Secretary) if it is determined that the basic model for which
the petition for waiver was submitted contains one or more design
characteristics that prevents testing of the basic model according to
the prescribed test procedures, or if the prescribed test procedures
may evaluate the basic model in a manner so unrepresentative of its
true energy consumption characteristics as to provide materially
inaccurate comparative data. 10 CFR part 430.27(l). Petitioners must
include in their petition any alternate test procedures known to the
petitioner to evaluate the basic model in a manner representative of
its energy consumption. 10 CFR 430.27(b)(1)(iii). The Assistant
Secretary may grant the waiver subject to conditions, including
adherence to alternate test procedures. 10 CFR 430.27(l). Waivers
remain in effect pursuant to the provisions of 10 CFR 430.27(m).
The waiver process also allows the Assistant Secretary to grant an
interim waiver from test procedure requirements to manufacturers that
have petitioned DOE for a waiver of such prescribed test procedures. 10
CFR 430.27(a)(2); 430.27(g). An interim waiver remains in effect for a
period of 180 days or until DOE issues its determination on the
petition for waiver, whichever is sooner, and may be extended for an
additional 180 days, if necessary. 10 CFR 430.27(h).
II. Petition for Waiver of Test Procedure
On September 15, 2010, Electrolux filed a petition for waiver from
the test procedure applicable to residential electric refrigerators and
refrigerator-freezers set forth in 10 CFR Part 430, Subpart B, Appendix
A1. Electrolux is designing new refrigerator-freezers that contain
variable anti-sweat heater controls that detect a broad range of
temperature and humidity conditions, and respond by activating adaptive
heaters, as needed, to evaporate excess moisture. According to the
petitioner, Electrolux's technology is similar to that used by General
Electric Company (GE) and Whirlpool Corporation (Whirlpool) for
refrigerator-freezers which were the subject of petitions for waiver
published April 17, 2007 (72 FR 19189) and July 10, 2008 (73 FR 39684),
respectively. GE's waiver was granted on February 27, 2008. 73 FR
10425. Whirlpool's waiver was granted on May 5, 2009. 74 FR 20695.
Electrolux itself filed a petition for waiver from the test procedure
applicable to residential refrigerator-freezers for its similar models
in November 2008, which was published in the Federal Register on June
4, 2009. 74 FR 26853. DOE granted Electrolux's November 2008 petition
for waiver on December 15, 2009. 74 FR 66338. Subsequently, DOE granted
similar waivers for additional Electrolux refrigerator-freezers on
March 11, 2010 (75 FR 11530) and April 29, 2010 (75 FR 22584). Most
recently, DOE granted similar waivers to Samsung on March 18, 2010 (75
FR 13120) and August 3, 2010 (75 FR 45623); to Haier on June 7, 2010
(75 FR 32175); and to LG on August 19, 2010 (75 FR 51264).
In its September 2010 petition, as in its three earlier petitions,
Electrolux seeks a waiver from the existing DOE test procedure
applicable to refrigerators and refrigerator-freezers under 10 CFR part
430 because the existing test procedure takes neither ambient
[[Page 76964]]
humidity nor adaptive technology into account. Therefore, Electrolux
states that the test procedure does not accurately measure the energy
consumption of Electrolux's new refrigerator-freezers that feature
variable anti-sweat heater controls and adaptive heaters. Consequently,
Electrolux has submitted to DOE for approval an alternate test
procedure that would allow it to calculate the energy consumption of
this new product line correctly. Electrolux's alternate test procedure
is the same in all relevant particulars as that prescribed for GE,
Whirlpool, Samsung, Haier, LG and Electrolux itself for refrigerator-
freezers that are equipped with the same type of technology. The
alternate test procedure applicable to these products simulates the
energy used by the adaptive heaters in a typical consumer household, as
explained, for example, in the Decision and Order that DOE published in
the Federal Register on February 27, 2008 in response to GE's petition
for waiver described above. 73 FR 10425. DOE believes that it is in the
public interest to have similar products tested and rated for energy
consumption on a comparable basis.
III. Application for Interim Waiver
Electrolux also requests an interim waiver from the existing DOE
test procedure. Under 10 CFR 430.27(b)(2), each application for interim
waiver ``shall demonstrate likely success of the Petition for Waiver
and shall address what economic hardship and/or competitive
disadvantage is likely to result absent a favorable determination on
the Application for Interim Waiver.'' An interim waiver may be granted
if it is determined that the applicant will experience economic
hardship if the application for interim waiver is denied; if it appears
likely that the petition for waiver will be granted; and/or the
Assistant Secretary determines that it would be desirable for public
policy reasons to grant immediate relief pending a determination of the
petition for waiver. 10 CFR 430.27(g).
DOE has determined that Electrolux's application for interim waiver
does not provide sufficient market, equipment price, shipments and
other manufacturer impact information to permit DOE to evaluate the
economic hardship Electrolux might experience absent a favorable
determination on its application for interim waiver. DOE understands,
however, that absent an interim waiver, Electrolux's products would not
otherwise be tested and rated for energy consumption on a comparable
basis as equivalent GE, LG, Samsung, Haier and Whirlpool products for
which DOE previously granted waivers, and Electrolux would be required
to represent a higher energy consumption for essentially the same
product. Therefore, it appears likely that Electrolux's petition for
waiver will be granted. Moreover, it is desirable for public policy
reasons to grant Electrolux immediate relief pending a determination on
the petition for waiver since it is in the public interest to have
similar products tested and rated for energy consumption on a
comparable basis. As stated above, DOE has already granted similar
waivers because the test procedure does not accurately represent the
energy consumption of refrigerator-freezers containing relative
humidity sensors and adaptive control anti-sweat heaters. The rationale
for granting these waivers is equally applicable to Electrolux, which
has products containing similar relative humidity sensors and anti-
sweat heaters.
For the reasons stated above, DOE grants Electrolux's application
for interim waiver from testing of its refrigerator-freezer product
line containing relative humidity sensors and adaptive control anti-
sweat heaters. Therefore, it is ordered that:
The application for interim waiver filed by Electrolux is hereby
granted for Electrolux's refrigerator-freezer product line containing
relative humidity sensors and adaptive control anti-sweat heaters,
subject to the specifications and conditions below.
1. Electrolux shall not be required to test or rate its
refrigerator-freezer product line containing relative humidity sensors
and adaptive control anti-sweat heaters on the basis of the test
procedure under 10 CFR part 430 subpart B, appendix A1.
2. Electrolux shall be required to test and rate its refrigerator-
freezer product line containing relative humidity sensors and adaptive
control anti-sweat heaters according to the alternate test procedure as
set forth in section IV, ``Alternate test procedure.''
The interim waiver applies to the following basic model groups:
EI27BS* * * * FGUN26* * * * CFD26* * *
DOE makes decisions on waivers and interim waivers for only those
models specifically set out in the petition, not future models that may
or may not be manufactured by the petitioner. Electrolux may submit a
new or amended petition for waiver and request for grant of interim
waiver, as appropriate, for additional models of refrigerator-freezers
for which it seeks a waiver from the DOE test procedure. In addition,
DOE notes that grant of an interim waiver or waiver does not release a
petitioner from the certification requirements set forth at 10 CFR
430.62.
Further, this interim waiver is conditioned upon the presumed
validity of statements, representations, and documents provided by the
petitioner. DOE may revoke or modify this interim waiver at any time
upon a determination that the factual basis underlying the petition for
waiver is incorrect, or upon a determination that the results from the
alternate test procedure are unrepresentative of the basic models' true
energy consumption characteristics.
IV. Alternate Test Procedure
Electrolux's new line of refrigerator-freezers contains sensors
that detect ambient humidity and interact with controls that vary the
effective wattage of anti-sweat heaters to evaporate excess moisture.
The existing DOE test procedure cannot be used to calculate the energy
consumption of these features. The variable anti-sweat heater
contribution to the refrigerator-freezer's energy consumption is
entirely dependent on the ambient humidity of the test chamber, which
the DOE test procedure does not specify. The energy consumption of the
anti-sweat heaters will be modeled and added to the energy consumption
measured when the anti-sweat heaters are disabled. The anti-sweat
contribution to the product's total energy consumption will be
calculated using the same methodology that was set forth in the GE
petition. The objective of this approach is to simulate the average
energy used by the adaptive anti-sweat heaters as activated in
refrigerator-freezers of typical consumer households across the U.S.
To determine the conditions in a typical consumer household, GE
compiled historical data on the monthly average outdoor temperatures
and humidities for the top 50 metropolitan areas of the U.S. over
approximately the last 30 years. In light of the similarity of the
technologies at issue to the aforementioned GE products, Electrolux is
using the same data compiled by GE for its determination of the anti-
sweat heater energy use. Like GE, LG, Samsung, Haier and Whirlpool,
Electrolux includes in its test procedure a ``system-loss factor'' to
calculate system losses attributed to operating anti-sweat heaters,
controls, and related components.
For the duration of the interim waiver, Electrolux shall be
required to test the products listed above according to the test
procedures for residential electric refrigerator-freezers prescribed
[[Page 76965]]
by DOE at 10 CFR part 430, subpart B, appendix A1, except that, for the
Electrolux products listed above only:
(A) The following definition is added at the end of Section 1:
1.13 ``Variable anti-sweat heater control'' means an anti-sweat
heater where power supplied to the device is determined by an operating
condition variable(s) and/or ambient condition variable(s).
(B) Section 2.2 is revised to read as follows:
2.2 Operational conditions. The electric refrigerator or electric
refrigerator-freezer shall be installed and its operating conditions
maintained in accordance with HRF-1-1979, section 7.2 through section
7.4.3.3. except that the vertical ambient temperature gradient at
locations 10 inches (25.4 cm) out from the centers of the two sides of
the unit being tested is to be maintained during the test. Unless
shields or baffles obstruct the area, the gradient is to be maintained
from 2 inches (5.1 cm) above the floor or supporting platform to a
height one foot (30.5 cm) above the unit under test. Defrost controls
are to be operative. The anti-sweat heater switch is to be ``off''
during one test and ``on'' during the second test. In the case of an
electric refrigerator or refrigerator-freezer equipped with variable
anti-sweat heater control, the ``on'' test will be the result of the
calculation described in 6.2.3. Other exceptions are noted in 2.3, 2.4,
and 5.1 below.
(C) New section 6.2.3 is inserted after section 6.2.2.2.
6.2.3 Variable anti-sweat heater control test. The energy
consumption of an electric refrigerator or refrigerator-freezer with a
variable anti-sweat heater control in the ``on'' position
(Eon), expressed in kilowatt-hours per day, shall be
calculated equivalent to:
EON = E + (Correction Factor)
Where E is determined by 6.2.1.1, 6.2.1.2, 6.2.2.1, or 6.2.2.2,
whichever is appropriate, with the anti-sweat heater switch in the
``off'' position.
Correction Factor = (Anti-sweat Heater Power x System-loss Factor) x
(24 hrs/1 day) x (1 kW/1000 W)
Where:
Anti-sweat Heater Power = A1 * (Heater Watts at 5%RH)
+ A2 * (Heater Watts at 15%RH)
+ A3 * (Heater Watts at 25%RH)
+ A4 * (Heater Watts at 35%RH)
+ A5 * (Heater Watts at 45%RH)
+ A6 * (Heater Watts at 55%RH)
+ A7 * (Heater Watts at 65%RH)
+ A8 * (Heater Watts at 75%RH)
+ A9 * (Heater Watts at 85%RH)
+ A10 * (Heater Watts at 95%RH)
Where A1-A10 are obtained from the following table:
A1 = 0.034............................ A6 = 0.119.
A2 = 0.211............................ A7 = 0.069.
A3 = 0.204............................ A8 = 0.047.
A4 = 0.166............................ A9 = 0.008.
A5 = 0.126............................ A10 = 0.015.
Heater Watts at a specific relative humidity = the nominal watts
used by all heaters at that specific relative humidity, 72[deg]F
ambient, and DOE reference temperatures of fresh food (FF) average
temperature of 45 [deg]F and freezer (FZ) average temperature of 5
[deg]F.
System-loss Factor = 1.3
V. Summary and Request for Comments
Through today's notice, DOE grants Electrolux an interim waiver
from the specified portions of the test procedure applicable to
Electrolux's new line of refrigerator-freezers with variable anti-sweat
heater controls and adaptive heaters and announces receipt of
Electrolux's petition for waiver from those same portions of the test
procedure. DOE publishes Electrolux's petition for waiver in its
entirety pursuant to 10 CFR 430.27(b)(1)(iv). The petition contains no
confidential information. The petition includes a suggested alternate
test procedure and calculation methodology to determine the energy
consumption of Electrolux's specified refrigerator-freezers with
adaptive anti-sweat heaters. Electrolux is required to follow this
alternate procedure as a condition of its interim waiver, and DOE is
considering including this alternate procedure in its subsequent
Decision and Order.
DOE solicits comments from interested parties on all aspects of the
petition, including the suggested alternate test procedure and
calculation methodology. Pursuant to 10 CFR 430.27(b)(1)(iv), any
person submitting written comments to DOE must also send a copy of such

Re: Petition for Waiver and Application for Interim Waiver from the
Department of Energy Residential Refrigerator and Refrigerator-Freezer
Test Procedures by Electrolux Home Products, Inc.
Dear Secretary Zoi:
On behalf of our client, Electrolux Home Products, Inc.
(``Electrolux''), we respectfully submit this Petition for Waiver and
Application for Interim Waiver requesting exemption by the Department
of Energy from certain parts of the test procedure for determining
refrigerator-freezer energy consumption under 10 CFR Sec. 430.27. The
requested waiver will allow Electrolux to test its refrigerator-
freezers to the amended procedure set out by this Petition.
This Petition for Waiver contains no confidential business
information and may be released pursuant to Freedom of Information Act
requests.
I. Petition for Waiver
Electrolux seeks the Department's approval of this proposed
amendment to the refrigerator-freezer test procedure to be assured of
properly calculating the energy consumption and properly labeling its
new refrigerator-freezers. On February 27, 2008 and May 5, 2009, the
Department granted Petitions for Waiver filed respectively by General
Electric Corporation (``GE'') and Whirlpool Corporation (``Whirlpool'')
to establish a new methodology to calculate the energy consumption of a
refrigerator-
[[Page 76966]]
freezer when such a product contains adaptive anti-sweat heaters.\2\

Freezer Test Procedure, 74 Fed. Reg. 20695.
---------------------------------------------------------------------------
Electrolux has developed its own adaptive anti-sweat system that
uses a humidity sensor to operate the anti-sweat heaters. On November
6, 2008, Electrolux filed a Petition for Waiver and Application for
Interim Waiver from the test procedure applicable to residential
electric refrigerators and refrigerator-freezers. Having determined
that Electrolux is seeking a waiver similar to the one granted to GE,
on December 15, 2009, the Department granted Electrolux a Waiver.\3\
Since then, the Department has granted Electrolux two other Waivers
from the residential refrigerator and refrigerator-freezer test
procedures for additional basic models featuring identical adaptive
anti-sweat technology.\4\

Electrolux Home Products, Inc. From the Department of Energy
Residential Refrigerator and Refrigerator-Freezer Test Procedure, 75
Fed. Reg. 22584 (April 29, 2010).
---------------------------------------------------------------------------
Department regulations make clear that once a waiver has been
granted, the Department must take steps to incorporate the new
procedure and eliminate the need for continuing waivers:
Within one year of the granting of any waiver, the Department of
Energy will publish in the Federal Register a notice of proposed
rulemaking to amend its regulations so as to eliminate any need for the
continuation of such waiver. As soon thereafter as practicable, the
Department of Energy will publish in the Federal Register a final rule.
Such waiver will terminate on the effective date of such final rule.\5\
---------------------------------------------------------------------------
\5\ 10 CFR Sec. 430.27(m).
---------------------------------------------------------------------------
In the interim, however, Electrolux is developing and planning to
shortly introduce into the marketplace new models that use the
identical adaptive anti-sweat system addressed by the December 15,
2009, March 11, 2010, and April 29, 2010 Waivers granted to Electrolux
by the Department. Accordingly, Electrolux is filing this Petition for
Waiver and Application for Interim Waiver to address these new models.
The Department's regulations provide that the Assistant Secretary
will grant a petition for waiver upon ``determination that the basic
model for which the waiver was requested contains a design
characteristic which either prevents testing of the basic model
according to the prescribed test procedures, or the prescribed test
procedures may evaluate the basic model in a manner so unrepresentative
of its true energy consumption characteristics as to provide materially
inaccurate comparative data.'' \6\
---------------------------------------------------------------------------
\6\ 10 CFR Sec. 430.27(l).
---------------------------------------------------------------------------
Electrolux respectfully submits that sufficient grounds exist for
the Assistant Secretary to grant this Petition on both points. First,
the refrigerator energy test procedure does not allow the energy used
by Electrolux's new refrigerator to be accurately calculated. The new
refrigerator contains adaptive anti-sweat heaters (i.e., anti-sweat
heaters that respond to humidity conditions found in consumers' homes).
Since the test conditions specified by the test procedure neither
define required humidity conditions nor otherwise take ambient humidity
conditions into account in calculating energy consumption, the adaptive
feature of Electrolux's new refrigerator models cannot be properly
tested.
Second, testing Electrolux's new refrigerator models according to
the test procedure would provide results that do not accurately measure
the energy used by the new refrigerator.
A. The Refrigerator Energy Test Procedure
The test procedure for calculating energy consumption specifies
that the test chamber must be maintained at 90 [deg]Fahrenheit
(``F'').\7\ This ambient temperature is not typical of conditions in
most consumers' homes. Rather, it is intended to simulate the heat load
of a refrigerator in a 70 [deg]F ambient with typical usage by the
consumer. But the test procedure does not specify test chamber humidity
conditions. Sweat occurs on refrigerators when specific areas on the
unit are below the local dew point. Higher relative humidity levels
result in an increase of the dew point. Sweat has been addressed by
installing anti-sweat heaters on mullions and other locations where
sweat accumulates. Previous anti-sweat heaters operated at a fixed
amount of power and turned on or off regardless of the humidity or
amount of sweat on the unit.
---------------------------------------------------------------------------
\7\ 10 CFR Part 430, Subpart B, App. A1.
---------------------------------------------------------------------------
B. Electrolux's Proposed Modifications
The circumstances of this Petition are similar to those in the
Department's earlier decisions granting waiver petitions, including the
2001 Waiver granted in In the Matter of Electrolux Home Appliances.\8\
The test procedure at issue in Electrolux's 2001 waiver request was
originally developed when simple mechanical defrost timers were the
norm. Accordingly, Electrolux sought a test procedure waiver to
accommodate its advanced defrost timer. The Assistant Secretary, in
granting the Waiver, acknowledged the role of technology advances in
evaluating the need for test procedure waivers. With this current
Petition, Electrolux again seeks to change how it tests its new models
to take into account advances in sensing technology, i.e., sensors that
detect temperature and humidity conditions and interact with controls
to vary the effective wattage of anti-sweat heaters to evaporate excess
sweat.
---------------------------------------------------------------------------
\8\ Granting of the Application for Interim Waiver and
Publishing of the Petition for Waiver of Electrolux Home Products
from the DOE Refrigerator and Refrigerator-Freezer Test Procedure
(Case No. RF-005), 66 Fed. Reg. 40,689 (Aug. 3, 2001).
---------------------------------------------------------------------------
The Electrolux models, with the anti-sweat technology, subject to
this Petition are:
EI27BS * * *
FGUN26 * * *
CFD26 * * *
As with the models covered by the prior petitions, Electrolux
proposes to run the energy-consumption test with the anti-sweat heater
switch in the ``off'' position and then, because the test chamber is
not humidity-controlled, to add to that result the kilowatt hours per
day derived by calculating the energy used when the anti-sweat heater
is in the ``on'' position. This contribution will be calculated by the
same method that was proposed by GE and Whirlpool in their Petitions
for Waiver,\9\ as well as by Electrolux in its earlier Petitions. The
objective of the proposed approach is to simulate the average energy
used by the adaptive anti-sweat heaters as activated in typical
consumer households across the United States.

---------------------------------------------------------------------------
In formulating its Petition, GE conducted research to determine the
[[Page 76967]]
average humidity level experienced across the United States. The result
of this research was that GE was able to determine the probability that
any U.S. household would experience certain humidity conditions during
any month of the year. This data was consolidated into 10 bands each
representing a 10% range of relative humidity. In submitting this
Petition, Electrolux is confirming the validity of using such bands to
represent the average humidity experienced across the United States and
will adopt the same population weighting as proposed by GE. The bands
proposed by GE are as follows:

Since system losses are involved with operating anti-sweat heaters,
Electrolux proposes to include in the calculation a factor to account
for such energy. This additional energy includes the electrical energy
required to operate the anti-sweat heater control and related
components, and the additional energy required to increase compressor
run time to remove heat introduced into the refrigerator compartments
by the anti-sweat heater. Based on Electrolux's experience, this
``System-loss Factor'' is 1.3. Simply stated, the Correction Factor
that Electrolux proposes to add to the energy-consumption test results
obtained with the anti-sweat heater switch in the ``off'' position is
calculated as follows:
Correction Factor = (Anti-sweat Heater Power x System-loss Factor) x
(24 hours/1 day) x (1 kW/1000 W)
Continue by calculating the national average power in watts used by
the anti-sweat heaters. This is done by totaling the product of
constants A1-A10 multiplied by the respective heater watts used by a
refrigerator operating in the median percent relative humidity for that
band and the following standard refrigerator conditions:
Ambient temperature of 72 [deg]F;
Fresh food (FF) average temperature of 45 [deg]F; and
Freezer (FZ) average temperature of 5 [deg]F.
Anti-sweat Heater Power = A1 * (Heater Watts at 5% RH) + A2 *
(Heater Watts at 15% RH) + A3 * (Heater Watts at 25% RH) + A4 *
(Heater Watts at 35% RH) + A5 * (Heater Watts at 45% RH) + A6 *
(Heater Watts at 55% RH) + A7 * (Heater Watts at 65% RH) + A8 *
(Heater Watts at 75% RH) + A9 * (Heater Watts at 85% RH) + A10 *
(Heater Watts at 95% RH)
As explained above, bands A1-A10 were selected as representative of
humidity conditions in all U.S. households. Utilizing such weighed
bands will allow the calculation of the national average energy
consumption for each product.
Based on the above, Electrolux proposes to test its new models as
if the test procedure were modified to calculate the energy of the unit
with the anti-sweat heaters in the on position as equal to the energy
of the unit tested with the anti-sweat heaters in the off position plus
the Anti-Sweat Heater Power times the System Loss Factor (expressed in
KWH/YR).
II. Application for Interim Waiver
Pursuant to Department regulations, the Assistant Secretary will
grant an Interim Waiver ``if it is determined that the applicant will
experience economic hardship if the Application for Interim Waiver is
denied, if it appears likely that the Petition for Waiver will be
granted, and/or the Assistant Secretary determines that it would be
desirable for public policy reasons to grant immediate relief pending a
determination on the Petition for Waiver.'' \10\
---------------------------------------------------------------------------
\10\ 10 CFR 430.27(g).
---------------------------------------------------------------------------
The DOE letter granting the Electrolux Interim Waiver recognized
that:
* * * public policy would favor granting Electrolux an Interim
Waiver, pending determination of the Petition for Waiver. On February
27, 2008, DOE granted the General Electric Company (``GE'') a waiver
from the refrigerator-freezer test procedure because it takes neither
ambient humidity nor adaptive technology into account. 73 FR 10425. The
test procedure would not accurately represent the energy consumption of
refrigerator-freezers containing relative humidity sensors and adaptive
control anti-sweat heaters. This argument is equally applicable to
Electrolux, which has products containing similar relative humidity
sensors and anti-sweat heaters. Electrolux is seeking a very similar
waiver to the one DOE granted to GE, with the same alternate test
procedure, and it is very likely Electrolux's Petition for Waiver will
be granted.
As Electrolux noted in its November 6, 2008, July 13, 2009, and
December 4, 2009 Petitions for Waiver and Applications for Interim
Waiver, the Company could have designed its adaptive anti-sweat system
so that the anti-sweat heaters showed no impact during energy testing.
However, like GE and Whirlpool Corporation, Electrolux is following the
intent of the regulations to more accurately represent the energy
consumed by the new refrigerators when used in the home.
In addition to more fairly and accurately representing the actual
energy usage of appliances equipped with this technology, anti-sweat
heaters are now a well-recognized and widely used technology in the
industry. The alternate test procedure that is the subject of this
Waiver request is now the established method by which the energy
performance of anti-sweat heaters is measured, and Electrolux has
invested heavily to implement this procedure for its new models.
Consequently, requiring Electrolux to use the energy test procedure at
10 CFR Sec. 430.27 would impose an economic hardship on the Company.
The adaptive anti-sweat system in the Electrolux models referenced
above is similar to those addressed by the December 15, 2009, March 11,
2010, and April 29, 2010 Waivers granted to Electrolux by the
[[Page 76968]]
Department.\11\ Accordingly, Electrolux respectfully submits that
sufficient grounds exist for the Assistant Secretary to grant the
Electrolux Application for Interim Waiver.
---------------------------------------------------------------------------
\11\ See supra notes 2-3.

III. Conclusion
Electrolux urges the Assistant Secretary to grant its Petition for
Waiver and Application for Interim Waiver to allow Electrolux to test
its new refrigerator models as noted above. Granting Electrolux's
Petition for Waiver will encourage the introduction of advanced
technologies while providing proper consideration of energy
consumption.
