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.

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.
    DOE solicits comments from interested parties on all aspects of the 
petitions, including the suggested alternate test procedure and 
calculation methodology. Any person submitting written comments to DOE 
must also send a copy of such comments to the petitioner. The contact

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:

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 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:

    Please feel free to contact me if you have any questions 
regarding this Application for Petition for Waiver and Application 
for Interim Waiver. I will be happy to discuss should any questions 
arise.
