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 electric refrigerators and 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 that measure
the energy efficiency, energy use, or estimated annual operating costs
of a covered product, and that are not unduly burdensome to conduct.
(42 U.S.C. 6293(b)(3)) The test procedure for electric refrigerators
and electric 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 products. The Assistant Secretary for Energy Efficiency and
Renewable Energy (the Assistant Secretary) will grant a waiver 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 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. 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(g). An interim waiver remains in effect for 180 days or
until DOE issues its determination on the petition for waiver,
whichever occurs earlier. DOE may extend an interim waiver for an
additional 180 days. 10 CFR 430.27(h).
II. Petition for Waiver of Test Procedure and Application for Interim
Waiver
On December 13 and 26, 2013, Samsung submitted petitions 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. Samsung is seeking a waiver because it is
developing new refrigerator-freezers that incorporate a dual-compressor
design that is not contemplated under DOE's test procedure. In its
petitions, Samsung seeks a waiver from the existing DOE test procedure
applicable to refrigerators and refrigerator-freezers under 10 CFR part
430 for the company's dual-compressor products. In its petitions,
Samsung has set forth an alternate test procedure and notes in support
of its petition that DOE has already granted Sub-Zero a similar waiver
pertaining to the use of dual compressor-equipped refrigerators. See 76
FR 71335 (November 17, 2011) (interim waiver) and 77 FR 5784 (February
6, 2012) (Decision and Order). DOE has also granted an interim waiver
for products of this type to LG. See 77 FR 44603 (July 30, 2012). While
Samsung has acknowledged that its products have some differences from
the ones addressed by the Sub-Zero waiver, Samsung asserts that the
procedure outlined in that waiver will be compatible with its product.
In addition, Samsung requests that it be permitted to use the alternate
test procedure that DOE has already permitted Sub-Zero and LG to use in
response to similar waiver requests pertaining to the testing of
refrigerator-freezers that use shared dual compressors, with minor
modification suggested below:
Before: 5.2.1.4 Dual Compressor Systems with dual Automatic Defrost
With Minor Change: 5.2.1.4 Dual Compressor Systems with Automatic
Defrost (i=1 is mono, i=2 is dual)
Samsung also requests an interim waiver from the existing DOE test
procedure. 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. See 10 CFR
430.27(g).
DOE has determined that Samsung'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 Samsung might experience absent a favorable
determination on its application for interim waiver. DOE recognizes,
however, that the DOE test procedure for dual compressor systems
primarily addresses independent, sealed systems, which differ from the
shared system used by the models listed in Samsung's petition. As a
result, it is not possible to test these products using the DOE test
procedure, and use of the test procedure would provide test results so
unrepresentative as to provide materially inaccurate comparative data.
DOE reviewed the alternate procedure and determined that it will
alleviate the
[[Page 3795]]
testing problems associated with Samsung's implementation of a dual
compressor system. Therefore, it appears likely that Samsung's petition
for waiver will be granted. Previously, DOE granted GE, Samsung, LG,
and Sub-Zero similar waivers pertaining to the use of dual compressor-
equipped refrigerators. See 78 FR 38699 (June 27, 2013); 78 FR 35899
(June 14, 2013); 78 FR 18327 (March 26, 2013); and 77 FR 5784 (February
6, 2012).
For the reasons stated above, DOE grants Samsung's application for
interim waiver from testing of its refrigerator-freezer product line
containing dual compressors. Therefore, it is ordered that:
The application for interim waiver filed by Samsung is hereby
granted for Samsung's refrigerator-freezer product lines that
incorporate dual compressors subject to the following specifications
and conditions below. Samsung shall be required to test and rate its
refrigerator-freezer product line containing dual compressors
according to the alternate test procedure as set forth in section
III, ``Alternate test procedure.''
The interim waiver applies to the following basic models group:
RF34H99****
RF33H99****
DOE makes decisions on waivers and interim waivers for only
those models specifically set out in the petition, not future models
that may be manufactured by the petitioner. Samsung 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 granting of an interim waiver or waiver
does not release a petitioner from the certification requirements
set forth at 10 CFR part 429.
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.
III. Alternate Test Procedure
EPCA requires that manufacturers use DOE test procedures to make
representations about the energy consumption and energy consumption
costs of products covered by the statute. (42 U.S.C. 6293(c))
Consistent representations are important for manufacturers to use in
making representations about the energy efficiency of their products
and to demonstrate compliance with applicable DOE energy conservation
standards. Pursuant to its regulations applicable to waivers and
interim waivers from applicable test procedures at 10 CFR 430.27, DOE
will consider setting an alternate test procedure for Samsung in a
subsequent Decision and Order.
During the period of the interim waiver granted in this notice,
Samsung shall test the products listed above according to the test
procedures for residential electric refrigerator-freezers prescribed by
DOE at 10 CFR part 430, subpart B, appendix A1, except that, for the
Samsung products listed above only, include:
5.2.1.4 Dual Compressor Systems with Automatic Defrost (i=1 is
mono, i=2 is dual). The two-part test method in section 4.2.1 must be
used, and the energy consumption in kilowatt-hours per day shall be
calculated equivalent to:
[GRAPHIC] [TIFF OMITTED] TN23JA14.063
Where:
1440 = number of minutes in a day
ET is the test cycle energy (kWh/day);
i is the variable that can equal to 1, 2 or more that identifies the
compartment with distinct defrost system;
D is the total number of compartments with distinct defrost systems;
EP1 is the dual compressor energy expended during the first part of
the test (it is calculated for a whole number of freezer compressor
cycles at least 24 hours in duration and may be the summation of
several running periods that do not include any precool, defrost, or
recovery periods);
T1 is the length of time for EP1 (minutes);
EP2i is the total energy consumed during the second (defrost) part
of the test being conducted for compartment i. (kWh);
T2i is the length of time (minutes) for the second (defrost) part of
the test being conducted for compartment i.
CTi is the compressor on time between defrosts for only compartment
i. CTi for compartment i with long time automatic defrost system is
calculated as per 10 CFR part 430 subpart B appendix A1 clause
5.2.1.2. CTi for compartment i with variable defrost system is
calculated as per 10 CFR part 430 subpart B appendix A1 clause
5.2.1.3. (hours rounded to the nearest tenth of an hour).
Stabilization:
The test shall start after a minimum 24 hours stabilization run for
each temperature control setting.
Steady State for EP1:
The temperature average for the first and last compressor cycle of
the test period must be within 1.0 [deg]F (0.6 [deg]C) of the test
period temperature average for each compartment. Make this
determination for the fresh food compartment for the fresh food
compressor cycles closest to the start and end of the test period. If
multiple segments are used for test period 1, each segment must comply
with above requirement.
Steady State for EP2i:
The second (defrost) part of the test must be preceded and followed
by regular compressor cycles. The temperature average for the first and
last compressor cycle of the test period must be within 1.0 [deg]F (0.6
[deg]C) of the EP1 test period temperature average for each
compartment.
Test Period for EP2i, T2i:
EP2i includes precool, defrost, and recovery time for compartment
i, as well as sufficient dual compressor steady state run cycles to
allow T2i to be at least 24 hours. The test period shall start at the
end of a regular freezer compressor on-cycle after the previous defrost
occurrence (refrigerator or freezer). The test period also includes the
target defrost and following regular freezer compressor cycles, ending
at the end of a regular freezer compressor on cycle before the next
defrost occurrence (refrigerator or freezer). If the previous condition
does not meet 24 hours time, additional EP1 steady state segment data
could be included. Steady state run cycle data can be utilized in EP1
and EP2i.
Test Measurement Frequency:
Measurements shall be taken at regular interval not exceeding 1
minute.
[End of 5.2.1.4]
IV. Summary and Request for Comments
Through today's notice, DOE grants Samsung an interim waiver from
the specified portions of the test procedure applicable to Samsung's
line of refrigerator-freezers with dual compressors and announces
receipt of Samsung's petitions for waiver from those same portions of
the test procedure. DOE publishes Samsung's petitions for waiver in its
entirety. The
[[Page 3796]]
petitions include a suggested alternate test procedure to determine the
energy consumption of Samsung's specified refrigerator-freezers with
dual compressors. Samsung 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.

Assistant Secretary, Energy Efficiency and Renewable Energy
United States Department of Energy
Forrestal Building (Mail Station EE-1)

Washington, DC 20585
Dear Assistant Secretary Danielson:
Samsung Electronics America, Inc. (``Samsung'') respectfully
submits the Application for Petition for Waiver and Application for
Interim Waiver to the Department of Energy (``DOE'' or ``the
Department'') regards to Samsung's residential refrigerator-freezers
that use shared dual compressors.
Reasoning
10 CFR Part 430.27(a)(1) allows a person to submit a petition to
waive for a particular basic model any requirements of Sec. 430.23
when (1) the basic model contains one or more design characteristics
which either prevent testing of the basic model according to the
prescribed test procedures, or (2) 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.
Current test procedures as prescribed in Appendix A1 to Subpart
B of 10 Part 430 do not adequately provide a way for Samsung to
accurately represent the energy consumption of its refrigerator-
freezers that use shared dual compressors. Meanwhile, based on
similar situations, DOE has already granted a waiver to Sub-Zero in
77 FR 5784 on February 6, 2012, and similarly, an interim waiver to
LG in 77 FR 44603 on July 30, 2012.
However, unlike Subzero's design which features two compressors,
two evaporators, and two defrost heaters, Samsung's design features
two compressors, four evaporators, and three defrost heaters.
Samsung's design features four compartments that have their own
evaporators. Three compartments, freezer/convertible/fresh food
compartment, are accessible with an exterior door and the fourth ice
room compartment is a sub compartment and located inside of the
fresh food compartment. Defrost heaters are adopted at three
evaporators (freezer/convertible/ice room) except the fresh food
compartment evaporator and those heaters operate all together at the
same time according to the control logic. So essentially, there is
only one defrost type. Despite these differences of the composition,
Samsung believes that the test procedure, as prescribed in the
waiver granted to Subzero and in the interim waiver granted to LG,
is equally applicable and appropriate.
More specifically, Samsung's residential refrigerator-freezers
that use shared dual compressors can be tested and calculate to a
reasonable result with same test procedure granted to Subzero's
waiver because the test procedure of Subzero's waiver adopt a
multiple defrost system of 1, 2 or more compartment with distinct
defrost system and Samsung's dual units have one defrost system
despite of having four compartments and three defrost heaters as
explained above.
Therefore, Samsung respectfully requests a waiver and an interim
waiver for the alternate test procedure that DOE has already granted
Sub-Zero and LG pertaining to the refrigerator-freezers that use
shared dual compressors, with minor modification suggested below:
Before: 5.2.1.4 Dual Compressor Systems with dual Automatic Defrost
With Minor Change: 5.2.1.4 Dual Compressor Systems with Automatic
Defrost (i=1 is mono, i=2 is dual)
Alternate Test Procedure
Replace the multiple defrost system section 5.2.1.4 of Appendix
A1 with the following:
5.2.1.4 Dual Compressor Systems with Automatic Defrost. The two-
part test method in section 4.2.1 must be used, and the energy
consumption in kilowatt-hours per day shall be calculated equivalent
to:
[GRAPHIC] [TIFF OMITTED] TN23JA14.064
Where:
1440 = number of minutes in a day
ET is the test cycle energy (kWh/day);
i is the variable that can equal to 1, 2 or more that
identifies the compartment with distinct defrost system;
D is the total number of compartments with distinct defrost
systems;
EP1 is the dual compressor energy expended during the first
part of the test (it is calculated for a whole number of freezer
compressor cycles at least 24 hours in duration and may be the
summation of several running periods that do not include any
precool, defrost, or recovery periods);
T1 is the length of time for EP1 (minutes);
EP2i is the total energy consumed during the second
(defrost) part of the test being conducted for compartment i. (kWh);
T2i is the length of time (minutes) for the second
(defrost) part of the test being conducted for compartment i.
CTi is the compressor on time between defrosts for only
compartment i. CTi for compartment i with long time automatic
defrost system is calculated as per 10 CFR part 430 subpart B
appendix A1 clause 5.2.1.2. CTi for compartment i with variable
defrost system is calculated as per 10 CFR part 430 subpart B
appendix A1 clause 5.2.1.3. (hours rounded to the nearest tenth of
an hour).
Stabilization:
The test shall start after a minimum 24 hours stabilization run
for each temperature control setting.
Steady State for EP1:
The temperature average for the first and last compressor cycle
of the test period must be within 1.0 [deg]F (0.6 [deg]C) of the
test period temperature average for each compartment. Make this
determination for the fresh food compartment for the fresh food
compressor cycles closest to the start and end of the test period.
If multiple segments are used for test period 1, each segment must
comply with above requirement.
Steady State for EP2i:
The second (defrost) part of the test must be preceded and
followed by regular compressor cycles. The temperature average for
the first and last compressor cycle of the test period must be
within 1.0 [deg]F (0.6 [deg]C) of the EP1 test period temperature
average for each compartment.
Test Period for EP2i, T2i:
[[Page 3797]]
EP2i includes precool, defrost, and recovery time for
compartment i, as well as sufficient dual compressor steady state
run cycles to allow T2i to be at least 24 hours. The test period
shall start at the end of a regular freezer compressor on-cycle
after the previous defrost occurrence (refrigerator or freezer). The
test period also includes the target defrost and following regular
freezer compressor cycles, ending at the end of a regular freezer
compressor oncycle before the next defrost occurrence (refrigerator
or freezer). If the previous condition does not meet 24 hours time,
additional EP1 steady state segment data could be included. Steady
state run cycle data can be utilized in EP1 and EP2i.
Test Measurement Frequency:
Measurements shall be taken at regular interval not exceeding 1
minute.
Request
For the reasons that DOE described in its granting of waiver and
interim waiver for Sub-Zero and LG for refrigerator-freezers with
shared dual compressors, Samsung believes that the expeditious
granting of Waiver and Interim Waiver for the model listed below is
warranted:
