Notice of Petition for Waiver of LG
Electronics USA, Inc. From the
Department of Energy Room Air
Conditioner Test Procedure and Notice
of Grant of Interim Waiver
Office of Energy Efficiency and
Renewable Energy, Department of
Energy.
ACTION: Notice of petition for waiver and
grant of an interim waiver, and request
for comments.
AGENCY:
This document announces
receipt of and publishes a petition for
waiver from LG Electronics USA, Inc.
(‘‘LG’’), which seeks an exemption from
the U.S. Department of Energy (‘‘DOE’’)
test procedure used for determining the
efficiency of specified room air
conditioner basic models. LG seeks to
use an alternate test procedure to
address issues involved in testing the
basic models identified in its petition.
According to LG, the current DOE test
procedure for room air conditioners,
which provides for testing at full-load
performance only, does not take into
account the benefits of room air
conditioners that use variable-speed
compressors (‘‘variable speed air
conditioners’’), with their part-load
performance characteristics, and
misrepresents their actual energy
consumption. LG requests that it be
permitted to test the specified basic
models at four rating conditions instead
of a single rating condition and to
calculate the test unit’s weightedaverage combined energy efficiency
ratio (CEER), which can then be
compared to the expected performance
of a comparable single-speed room air
conditioner across the same four rating

conditions. The performance
improvement would be applied to the
measured performance of the variablespeed room air conditioner when tested
under the high-temperature rating
condition of the DOE test procedure for
room air conditioners to determine the
test unit’s final rated CEER value. DOE
grants LG an interim waiver from the
DOE’s room air conditioner test
procedure for the specified basic
models, subject to use of the alternate
test procedure as set forth in the Interim
Waiver Order. DOE solicits comments,
data, and information concerning LG’s
petition and its suggested alternate test
procedure to inform its final decision on
LG’s waiver request.

SUPPLEMENTARY INFORMATION:
I. Background and Authority
The Energy Policy and Conservation
Act of 1975 (‘‘EPCA’’ or ‘‘the Act’’),1
Public Law 94–163 (42 U.S.C. 6291–
6317, as codified), among other things,
authorizes DOE to regulate the energy
efficiency of a number of consumer
products and industrial equipment.
Title III, Part B 2 of EPCA established the
Energy Conservation Program for
Consumer Products Other Than
Automobiles, a program that includes
room air conditioners, which are the
subject of this document. (42 U.S.C.
6292(a)(2)).
DOE regulations set forth at 10 CFR
430.27 contain provisions that allow
any interested person to seek a waiver
from test procedure requirements for a
particular basic model when the
petitioner’s basic model for which the
petition for waiver was submitted
contains one or more design
characteristics that either (1) prevent
testing according to the prescribed test
procedure, or (2) cause the prescribed
test procedures to evaluate the basic
model in a manner so unrepresentative
of its true energy consumption
characteristics as to provide materially
inaccurate comparative data. 10 CFR
1 All references to EPCA in this document refer
to the statute as amended through the EPS
Improvement Act of 2017, Public Law 11–115
(January 12, 2018).
2 For editorial reasons, upon codification in the
U.S. Code, Part B was re-designated Part A.

430.27(f)(2). A petitioner must include
in its petition any alternate test
procedures known to the petitioner to
evaluate the basic model in a manner
representative of its energy
consumption characteristics. 10 CFR
430.27(b)(1)(iii).
DOE may grant the waiver subject to
conditions, including adherence to
alternate test procedures. 10 CFR
430.27(f)(2). As soon as practicable after
the granting of any waiver, DOE 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. 10
CFR 430.27(l). As soon thereafter as
practicable, DOE will publish in the
Federal Register a final rule. Id.
The waiver process also provides that
DOE may grant an interim waiver if it
appears likely that the underlying
petition for waiver will be granted and/
or if DOE determines that it would be
desirable for public policy reasons to
grant immediate relief pending a
determination on the underlying
petition for waiver. 10 CFR 430.27(e)(2).
Within one year of issuance of an
interim waiver, DOE will either: (i)
Publish in the Federal Register a
determination on the petition for
waiver; or (ii) publish in the Federal
Register a new or amended test
procedure that addresses the issues
presented in the waiver. 10 CFR
430.27(h)(1). When DOE amends the test
procedure to address the issues
presented in a waiver, the waiver will
automatically terminate on the date on
which use of that test procedure is
required to demonstrate compliance. 10
CFR 430.27(h)(2).
II. LG’s Petition for Waiver and Petition
for Interim Waiver
On April 6, 2018, LG filed a petition
for waiver and a petition for interim
waiver from the test procedure
applicable to room air conditioners set
forth in appendix F. According to LG,
the current DOE test procedure for room
air conditioners, which provides for
testing at full-load performance only
(i.e., at a single indoor and hightemperature outdoor operating
condition), does not take into account
the benefits of variable-speed room air
conditioners, with their part-load
performance characteristics, and
misrepresents their actual energy
consumption.3 Appendix F requires
room air conditioners be tested only
with full-load performance, in part, as a
result of DOE having previously
concluded that widespread use of partload technology in room air
conditioners was not likely to be
stimulated by the development of a partload metric. 76 FR 972, 1016 (January 6,
2011).
LG states that variable-speed room air
conditioners use frequency controls
constantly to adjust the compressor
rotation speed to maintain the desired
temperature in the home without
turning the motor on and off; that the
compressor responds automatically to
surrounding conditions to operate in the
most efficient possible manner; and that
this results in both dramatic energy
savings and faster cooling compared to
a room air conditioner without a
variable-speed compressor. LG asserted
that this ability to adjust to conditions
results in both dramatic energy savings
and faster cooling compared to products
room air conditioners without variablespeed compressors. LG further stated
that variable-speed room air
conditioners also have a higher/lower
operating range (10 Hz to 120 Hz). LG
asserts that because the DOE test
procedure does not account for partload characteristics, the results of the
test procedure are not representative of
the actual energy consumption of
variable-speed room air conditioners.
LG also requests an interim waiver
from the existing DOE test procedure.
DOE will grant an interim waiver if it
appears likely that the petition for
waiver will be granted, and/or if DOE
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(e)(2).
DOE understands that, absent an
interim waiver, the test procedure does
not accurately measure the energy
consumption of variable-speed room air
conditioners, and without waiver relief,
the part-load characteristics of the basic
models identified in LG’s petition
would not be captured.
III. Requested Alternate Test Procedure
EPCA requires that manufacturers use
DOE test procedures when making
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, and after
consideration of public comments on
the petition, DOE will consider setting
an alternate test procedure for the
equipment identified by LG in a
subsequent Decision and Order.
In its petition, LG requests testing the
basic models listed in the petition
according to the test procedure for room
air conditioners prescribed by DOE in
appendix F, except that the variablespeed room air conditioner would be
tested at four rating conditions instead
of a single rating condition. The
suggested test conditions are presented
in Table III.1.

Under the suggested test procedure,
the test unit’s weighted-average
combined energy efficiency ratio (CEER)
metric is calculated from the individual
CEER values obtained at the four rating
conditions, with the weighting factors
derived from the fractional temperature
bin hours for each rating temperature
provided in Table 19 of DOE’s test
3 The specific basic models for which the petition
applies are room air conditioner basic models LG
LW2217IVSM, LG LW1817IVSM, and LG
LW1517IVSM. These basic model names were
provided by LG in its April 6, 2018 petition.

procedure for central air conditioners
(10 CFR part 430, subpart B, appendix
M (‘‘appendix M’’)). This weightedaverage value is adjusted to normalize it
against the expected weighted-average
CEER under the same four rating
conditions of a comparable single-speed
room air conditioner that has the same
performance as the variable-speed test
unit at the 95 degree Fahrenheit (°F) test
condition but differing performance at
the other rating conditions due to
optimization of the refrigeration system
efficiency through compressor speed
adjustments to better match the cooling
load and eliminate cycling losses. This
average performance improvement
resulting from the implementation of a
variable-speed compressor across
multiple rating conditions would then
be applied to the measured performance
of the variable-speed room air
conditioner when tested at the 95 °F
rating condition according to appendix
F to determine the test unit’s final rated
CEER value. LG states that this approach
takes into account performance and
efficiency improvements associated
with variable-speed room air
conditioners as compared to room air
conditioners with single-speed
compressors and isolates the effects just
attributable to the variable speed
operation.

IV. Grant of an Interim Waiver
DOE has reviewed the marketing
materials, website, and brochure for the
specific basic models for which this
petition applies. The materials that DOE
reviewed support LG’s assertion of the
part-load characteristics of the variablespeed room air conditioners and that the
DOE test procedure may evaluate the
basic models in a manner
unrepresentative of their true energy
consumption characteristics. In
particular, the DOE test procedure does
not capture the relative efficiency
improvements that can be achieved by
variable-speed room air conditioners
over a range of operating conditions
compared to single-speed room air
conditioners. In the absence of an
alternate test procedure, the CEER
values of variable-speed room air
conditioners would suggest that such
room air conditioners would consume at
least as much energy annually as a
comparable single-speed room air
conditioner, despite the anticipated
VerDate Sep<11>2014
17:58 Jun 28, 2018
Jkt 244001
benefits of improved performance under
part-load conditions. Furthermore, DOE
has reviewed the alternate procedure
suggested by LG, along with additional
performance modeling and analysis
performed by DOE using rating
conditions specified in an industry
standard for single-package air
conditioning equipment with variable
speed compressors, American National
Standards Institute (‘‘ANSI’’)/AirConditioning, Heating, and Refrigeration
Institute (‘‘AHRI’’) Standard 210/
240:2008, ‘‘Performance Rating of
Unitary Air-Conditioning & Air-Source
Heat Pump Equipment.’’ Based on this
review it appears that the suggested
alternate test procedure, with additional
specification regarding the required
compressor speeds,4 will allow for a
more accurate measurement of
efficiency of the specified basic models
of variable-speed room air conditioners,
while alleviating the testing problems
associated with LG’s implementation of
room air conditioner testing for the
basic models specified in its petition.
Specifically, the suggested alternate test
procedure will produce CEER values for
the variable-speed room air conditioners
under the DOE test procedure’s existing
rating condition that will more
accurately reflect the average
performance improvement associated
with variable-speed compressors at
differing operating conditions (i.e.,
optimization of the refrigeration system
efficiency through compressor speed
adjustments to better match the cooling
load and eliminate cycling losses), as
compared to the performance changes
that comparable single-speed room air
conditioners would experience under
those same conditions. Consequently, it
appears likely that LG’s petition for
waiver will be granted. Furthermore,
DOE has determined that it is desirable
for public policy reasons to grant LG
immediate relief pending a
determination of the petition for waiver.
For the reasons stated, DOE has
granted an interim waiver to LG for the
specified room air conditioner basic
models in LG’s petition.
Therefore, DOE has issued an Order,
stating:
4 DOE derived the specification for determining
the intermediate compressor speed from the DOE
test procedure provisions for central air
conditioners with variable-speed compressors
(section 3.2.4.a of appendix M of 10 CFR part 430
subpart B).

(1) LG must test and rate the following
room air conditioner basic models with
the alternate test procedure set forth in
paragraph (2):
(A) LG LW2217IVSM, LG LW1817IVSM,
and LG LW1517IVSM
(2) The alternate test procedure for the
LG basic models listed in subparagraph
(1)(A) is the test procedure for room air
conditioners prescribed by DOE at
appendix F to subpart B of 10 CFR part
430 (Appendix F), except the combined
energy efficiency ratio (CEER) will be
determined as detailed below. All other
requirements of Appendix F and DOE’s
regulations remain applicable.
In Section 1, Definitions, add:
1.8 ‘‘Single-speed’’ means a type of
room air conditioner that does not
automatically adjust either the
compressor or fan speed, or both, based
on the detected outdoor conditions.
1.9 ‘‘Variable-speed’’ means a type
of room air conditioner that can
automatically adjust compressor and fan
speed, only compressor speed, or only
fan speed, based on the detected
outdoor conditions.
Add to the end of Section 2.1 Cooling:
For a variable-speed room air
conditioner, the cooling mode test shall
be repeated 3 additional times with
alternate outdoor test conditions, as
described in section 3.1 of this
appendix. For a variable-speed room air
conditioner, a psychrometric chamber
may alternatively be used in accordance
with ANSI/ASHRAE Standard 37–2009
(incorporated by reference; see § 430.3),
in place of a calorimeter chamber,
which is required in accordance with
appendix F. If using the psychrometric
chamber approach, set-up and
instrument the variable-speed room air
conditioner in accordance with Section
5 and Section 6 of ANSI/ASHRAE
Standard 37–2009, measure the indoor
cooling capacity in accordance with
Section 7.3 of ANSI/ASHRAE Standard
37–2009, and measure the average
electrical input power in Watts at the
nameplate voltage for each of the rating
test condition.
Add to the end of Section 3.1, Cooling
mode:
However, for variable-speed room air
conditioners, the set of four cooling
mode tests shall be conducted with the
following test conditions, presented in
Table 1 of this appendix.

(3) Representations. LG may not make
representations about the energy
efficiency of the basic models identified
in paragraph (1) for compliance,
marketing, or other purposes unless the
basic models have been tested in
accordance with the provisions in the
alternate test procedure and such
representations fairly disclose the
results of such testing in accordance
with 10 CFR 429.15(a).
(4) This interim waiver shall remain
in effect according to the provisions of
10 CFR 430.27.
(5) This interim waiver is issued to LG
on the condition that the statements,
representations, and information
provided by LG are valid. DOE may
revoke or modify this waiver at any time
if it determines the factual basis
underlying the petition for waiver is
incorrect, or the results from the
alternate test procedure are
unrepresentative of the basic models’
true energy consumption characteristics.
10 CFR 430.27(k)(1). Likewise, LG may
request that DOE rescind or modify the
interim waiver if LG discovers an error
in the information provided to DOE as
part of its petition, determines that the
interim waiver is no longer needed, or
for other appropriate reasons. 10 CFR
430.27(k)(2).
(6) Granting of this interim waiver
does not release LG from the
certification requirements set forth at 10
CFR part 429.
DOE makes decisions on waivers and
interim waivers for only those basic
models specifically set out in the
petition, not future models that may be
manufactured by the petitioner. LG may
submit a new or amended petition for
waiver and request for grant of interim
waiver, as appropriate, for additional
basic models of room air conditioners.
Alternatively, if appropriate, LG may
request that DOE extend the scope of a

In the Matter of:
Energy Efficiency Program: Test
Procedure for Room Air Conditioners
Petition of LG Electronics, Inc. for
Waiver and Application for Interim
Waiver of Test Procedure for Room
Air Conditioners
LG Electronics, Inc. (LG) respectfully
submits this Petition for Waiver and
Application for Interim Waiver 1 from
DOE’s test procedure for room air
conditioners (RACs). LG seeks a waiver
because the current test procedure does
not accurately measure the energy
consumption of RACs with variable
speed compressors (VSCs). LG requests
expedited treatment of the Petition and
Application.
LG is a manufacturer of room air
conditioners and other products sold
worldwide, including in the United
States. LG’s United States affiliate is LG
Electronics USA, Inc., with
headquarters at 1000 Sylvan Avenue,
Englewood Cliffs, NJ 07632 (tel. 201–

interim waiver).

816–2000). Its worldwide headquarters
are located at LG Twin Towers 20,
Yoido-dong, Youngdungpo-gu Seoul,
Korea 150–721; (tel. 011–82–2–3777–
1114); URL: http.www.LGE.com.
I. Basic Models for Which a Waiver
is Requested
The basic models for which a waiver
is requested are set forth in the
Appendix. They are distributed in
commerce under the LG brand name.
II. Need for the Requested Waiver
The LG RACs with VSC technology
are advanced, energy efficient products.
A VSC (inverter compressor) uses
frequency controls constantly to adjust
the compressor’s rotation speed to
maintain the desired temperature in the
home without turning the motor on and
off. The compressor responds
automatically to surrounding conditions
to operate in the most efficient possible
manner. This results in both dramatic
energy savings and faster cooling
compared to products without VSCs.
RACs with VSCs also have a higher/
lower operating range (10Hz to 120Hz)
than those without VSC.2
Unfortunately, the current DOE test
procedure for RACs provides that they
be tested only with full-load
performance.3 Thus, the RAC test
procedure does not take into account
the benefits of VSC, with its part-load
performance characteristics. This is
unlike the DOE test procedure for
central air conditioners, which provides
for testing with part-load performance
for VSCs.
DOE has recognized this serious
shortcoming in its RAC test procedure.
It has stated that this test procedure
‘‘does not measure the benefits of
technologies that improve part-load
performance.’’ 4
The current room AC test procedure
measures only the full-load performance at
outdoor ambient conditions of 95 °F dry-bulb
and 75 °F wet-bulb. Therefore, technologies
that improve part-load performance, such as
multiple-speed compressors and variableopening expansion devices, will not improve
the rated performance of a room AC under
the current test procedure.’’ 5
Indeed, DOE has correctly stressed that,
‘‘[i]n contrast, central ACs and heat
pumps are rated using multiple rating
points at different conditions.’’ 6 Finally,
2 To the best of LG’s knowledge, LG is the only
manufacturer of RAC basic models distributed in
commerce in the United States to incorporate
design characteristic(s) similar to those found in the
basic models that are the subject of this petition,
namely, RAC VSC technology.

DOE has said it intends to investigate
potential revision of the test procedure
‘‘to account for any benefits of
technologies that improve part-load
performance.’’ 7
At the moment, however, the DOE test
procedure for RACs does not include
any provision to account for the benefits
of the part-load performance of VSCs.
Therefore, the test procedure evaluates
the LG models with VSCs in a manner
that misrepresents their actual energy
consumption. LG urges that a waiver be
granted, for the basic models in the
Appendix, that will allow use of the
alternate test procedure discussed
below. The test procedure is designed to
take into account the energy savings
characteristics of VSCs, and will yield
results more representative of the actual
energy consumption of these products
than the current DOE test procedure.
And the rules provide that DOE ‘‘will
grant a waiver from the test procedure
requirements’’ in these circumstances.8
The waiver should continue until DOE
adopts an applicable amended test
procedure.
III. Proposed Alternate Test
Procedure
LG proposes the following alternate
test procedure to evaluate the
performance of the basic models listed
in the Appendix. The alternate test
procedure is the same as the existing
test procedure for RACs except that it
takes into account VSC part-load
characteristics. It does so by providing
for tests at a variety of load conditions.
Specifically:
LG shall be required to test the
performance of the basic models listed
in the Appendix hereto according to the
test procedure for room air conditioners
in 10 C.F.R. Part 430, Subpart B,
Appendix F, except as follows:
Add new Sections 1.8 and 1.9 to
Appendix F as follows:
‘‘1.8 ‘‘Single-speed’’ means a type of
room air conditioner that does not
automatically adjust either the
compressor or fan speed, or both, based
on the detected outdoor conditions.
1.9 ‘‘Variable-speed’’ means a type of
room air conditioner that can
automatically adjust compressor and fan
speed, only compressor speed, or only
fan speed, based on the detected
outdoor conditions.’’
Add the following at the end of Section
2.1 of Appendix F:
‘‘For a variable-speed room air
conditioner, the cooling mode test shall

appendix. For a variable-speed room air
conditioner, a psychrometric chamber
may alternatively be used in place of a
calorimeter chamber, in accordance
with ANSI/ASHRAE Standard 37–2009
(incorporated by reference; see § 430.3).
If using the psychrometric chamber
approach, set-up and instrument the

measure the indoor cooling capacity in
accordance with Section 7.3 of ANSI/

IV. Application for Interim Waiver
DEPARTMENT OF ENERGY
DEPARTMENT OF ENERGY
LG also hereby applies for an interim
waiver of the applicable test procedure
requirements for the LG basic models
set forth in the Appendix. LG meets the
criteria for an interim waiver.
LG’s Petition for Waiver is likely to be
granted because the test method
contained in 10 C.F.R. Part 430, Subpart
B, Appendix F clearly does not address
the VSC characteristics of these LG basic
models. Thus, the test procedure does
not accurately measure their energy
consumption. Without waiver relief, LG
would be subject to requirements that
are inapplicable to these products.
Additionally, LG will suffer economic
hardship and be at a competitive
disadvantage if it must wait to rate these
basic models pending a determination
on the petition for waiver.
DOE approval of LG’s interim waiver
application is also supported by sound
public policy. These LG products
employ advanced technology that
increases efficiency and reduces energy
consumption, while offering a new level
of affordable comfort to consumers.

DEPARTMENT OF ENERGY
[Case Number 2018-003; EERE-2018-BT-WAV-0006]
Notice of Petition for Waiver of LG Electronics USA, Inc. From
the Department of Energy Room Air Conditioner Test Procedure and Notice
of Grant of Interim Waiver
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Notice of petition for waiver and grant of an interim waiver,
and request for comments.
-----------------------------------------------------------------------
SUMMARY: This document announces receipt of and publishes a petition
for waiver from LG Electronics USA, Inc. (``LG''), which seeks an
exemption from the U.S. Department of Energy (``DOE'') test procedure
used for determining the efficiency of specified room air conditioner
basic models. LG seeks to use an alternate test procedure to address
issues involved in testing the basic models identified in its petition.
According to LG, the current DOE test procedure for room air
conditioners, which provides for testing at full-load performance only,
does not take into account the benefits of room air conditioners that
use variable-speed compressors (``variable speed air conditioners''),
with their part-load performance characteristics, and misrepresents
their actual energy consumption. LG requests that it be permitted to
test the specified basic models at four rating conditions instead of a
single rating condition and to calculate the test unit's weighted-
average combined energy efficiency ratio (CEER), which can then be
compared to the expected performance of a comparable single-speed room
air conditioner across the same four rating conditions. The performance
improvement would be applied to the measured performance of the
variable-speed room air conditioner when tested under the high-
temperature rating condition of the DOE test procedure for room air
conditioners to determine the test unit's final rated CEER value. DOE
grants LG an interim waiver from the DOE's room air conditioner test
procedure for the specified basic models, subject to use of the
alternate test procedure as set forth in the Interim Waiver Order. DOE
solicits comments, data, and information concerning LG's petition and
its suggested alternate test procedure to inform its final decision on
LG's waiver request.
DATES: Written comments and information are requested and will be
accepted on or before July 30, 2018.

SUPPLEMENTARY INFORMATION:
I. Background and Authority
The Energy Policy and Conservation Act of 1975 (``EPCA'' or ``the
Act''),\1\ Public Law 94-163 (42 U.S.C. 6291-6317, as codified), among
other things, authorizes DOE to regulate the energy efficiency of a
number of consumer products and industrial equipment. Title III, Part B
\2\ of EPCA established the Energy Conservation Program for Consumer
Products Other Than Automobiles, a program that includes room air
conditioners, which are the subject of this document. (42 U.S.C.
6292(a)(2)).
---------------------------------------------------------------------------
\1\ All references to EPCA in this document refer to the statute
as amended through the EPS Improvement Act of 2017, Public Law 11-
115 (January 12, 2018).
\2\ For editorial reasons, upon codification in the U.S. Code,
Part B was re-designated Part A.
---------------------------------------------------------------------------
DOE regulations set forth at 10 CFR 430.27 contain provisions that
allow any interested person to seek a waiver from test procedure
requirements for a particular basic model when the petitioner's basic
model for which the petition for waiver was submitted contains one or
more design characteristics that either (1) prevent testing according
to the prescribed test procedure, or (2) cause the prescribed test
procedures to evaluate the basic model in a manner so unrepresentative
of its true energy consumption characteristics as to provide materially
inaccurate comparative data. 10 CFR
[[Page 30718]]
430.27(f)(2). A petitioner must include in its petition any alternate
test procedures known to the petitioner to evaluate the basic model in
a manner representative of its energy consumption characteristics. 10
CFR 430.27(b)(1)(iii).
DOE may grant the waiver subject to conditions, including adherence
to alternate test procedures. 10 CFR 430.27(f)(2). As soon as
practicable after the granting of any waiver, DOE 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. 10 CFR 430.27(l). As soon thereafter as practicable, DOE will
publish in the Federal Register a final rule. Id.
The waiver process also provides that DOE may grant an interim
waiver if it appears likely that the underlying petition for waiver
will be granted and/or if DOE determines that it would be desirable for
public policy reasons to grant immediate relief pending a determination
on the underlying petition for waiver. 10 CFR 430.27(e)(2). Within one
year of issuance of an interim waiver, DOE will either: (i) Publish in
the Federal Register a determination on the petition for waiver; or
(ii) publish in the Federal Register a new or amended test procedure
that addresses the issues presented in the waiver. 10 CFR 430.27(h)(1).
When DOE amends the test procedure to address the issues presented in a
waiver, the waiver will automatically terminate on the date on which
use of that test procedure is required to demonstrate compliance. 10
CFR 430.27(h)(2).
II. LG's Petition for Waiver and Petition for Interim Waiver
On April 6, 2018, LG filed a petition for waiver and a petition for
interim waiver from the test procedure applicable to room air
conditioners set forth in appendix F. According to LG, the current DOE
test procedure for room air conditioners, which provides for testing at
full-load performance only (i.e., at a single indoor and high-
temperature outdoor operating condition), does not take into account
the benefits of variable-speed room air conditioners, with their part-
load performance characteristics, and misrepresents their actual energy
consumption.\3\ Appendix F requires room air conditioners be tested
only with full-load performance, in part, as a result of DOE having
previously concluded that widespread use of part-load technology in
room air conditioners was not likely to be stimulated by the
development of a part-load metric. 76 FR 972, 1016 (January 6, 2011).
---------------------------------------------------------------------------
\3\ The specific basic models for which the petition applies are
room air conditioner basic models LG LW2217IVSM, LG LW1817IVSM, and
LG LW1517IVSM. These basic model names were provided by LG in its
April 6, 2018 petition.
---------------------------------------------------------------------------
LG states that variable-speed room air conditioners use frequency
controls constantly to adjust the compressor rotation speed to maintain
the desired temperature in the home without turning the motor on and
off; that the compressor responds automatically to surrounding
conditions to operate in the most efficient possible manner; and that
this results in both dramatic energy savings and faster cooling
compared to a room air conditioner without a variable-speed compressor.
LG asserted that this ability to adjust to conditions results in both
dramatic energy savings and faster cooling compared to products room
air conditioners without variable-speed compressors. LG further stated
that variable-speed room air conditioners also have a higher/lower
operating range (10 Hz to 120 Hz). LG asserts that because the DOE test
procedure does not account for part-load characteristics, the results
of the test procedure are not representative of the actual energy
consumption of variable-speed room air conditioners.
LG also requests an interim waiver from the existing DOE test
procedure. DOE will grant an interim waiver if it appears likely that
the petition for waiver will be granted, and/or if DOE 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(e)(2).
DOE understands that, absent an interim waiver, the test procedure
does not accurately measure the energy consumption of variable-speed
room air conditioners, and without waiver relief, the part-load
characteristics of the basic models identified in LG's petition would
not be captured.
III. Requested Alternate Test Procedure
EPCA requires that manufacturers use DOE test procedures when
making 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, and after consideration of public comments on the petition, DOE
will consider setting an alternate test procedure for the equipment
identified by LG in a subsequent Decision and Order.
In its petition, LG requests testing the basic models listed in the
petition according to the test procedure for room air conditioners
prescribed by DOE in appendix F, except that the variable-speed room
air conditioner would be tested at four rating conditions instead of a
single rating condition. The suggested test conditions are presented in
Table III.1.
Table III.1--Indoor and Outdoor Inlet Air Test Conditions--Variable-Speed Room Air Conditioners
----------------------------------------------------------------------------------------------------------------
Evaporator inlet air, [deg]F Condenser inlet air, [deg]F
Test condition ---------------------------------------------------------------- Compressor speed
Dry bulb Wet bulb Dry bulb Wet bulb
----------------------------------------------------------------------------------------------------------------
Test Condition 1............ 80 67 95 75 Maximum.
Test Condition 2............ 80 67 92 72.5 Maximum.
Test Condition 3............ 80 67 87 69 Intermediate.
Test Condition 4............ 80 67 82 65 Minimum.
----------------------------------------------------------------------------------------------------------------
Under the suggested test procedure, the test unit's weighted-
average combined energy efficiency ratio (CEER) metric is calculated
from the individual CEER values obtained at the four rating conditions,
with the weighting factors derived from the fractional temperature bin
hours for each rating temperature provided in Table 19 of DOE's test
[[Page 30719]]
procedure for central air conditioners (10 CFR part 430, subpart B,
appendix M (``appendix M'')). This weighted-average value is adjusted
to normalize it against the expected weighted-average CEER under the
same four rating conditions of a comparable single-speed room air
conditioner that has the same performance as the variable-speed test
unit at the 95 degree Fahrenheit ([deg]F) test condition but differing
performance at the other rating conditions due to optimization of the
refrigeration system efficiency through compressor speed adjustments to
better match the cooling load and eliminate cycling losses. This
average performance improvement resulting from the implementation of a
variable-speed compressor across multiple rating conditions would then
be applied to the measured performance of the variable-speed room air
conditioner when tested at the 95 [deg]F rating condition according to
appendix F to determine the test unit's final rated CEER value. LG
states that this approach takes into account performance and efficiency
improvements associated with variable-speed room air conditioners as
compared to room air conditioners with single-speed compressors and
isolates the effects just attributable to the variable speed operation.
IV. Grant of an Interim Waiver
DOE has reviewed the marketing materials, website, and brochure for
the specific basic models for which this petition applies. The
materials that DOE reviewed support LG's assertion of the part-load
characteristics of the variable-speed room air conditioners and that
the DOE test procedure may evaluate the basic models in a manner
unrepresentative of their true energy consumption characteristics. In
particular, the DOE test procedure does not capture the relative
efficiency improvements that can be achieved by variable-speed room air
conditioners over a range of operating conditions compared to single-
speed room air conditioners. In the absence of an alternate test
procedure, the CEER values of variable-speed room air conditioners
would suggest that such room air conditioners would consume at least as
much energy annually as a comparable single-speed room air conditioner,
despite the anticipated benefits of improved performance under part-
load conditions. Furthermore, DOE has reviewed the alternate procedure
suggested by LG, along with additional performance modeling and
analysis performed by DOE using rating conditions specified in an
industry standard for single-package air conditioning equipment with
variable speed compressors, American National Standards Institute
(``ANSI'')/Air-Conditioning, Heating, and Refrigeration Institute
(``AHRI'') Standard 210/240:2008, ``Performance Rating of Unitary Air-
Conditioning & Air-Source Heat Pump Equipment.'' Based on this review
it appears that the suggested alternate test procedure, with additional
specification regarding the required compressor speeds,\4\ will allow
for a more accurate measurement of efficiency of the specified basic
models of variable-speed room air conditioners, while alleviating the
testing problems associated with LG's implementation of room air
conditioner testing for the basic models specified in its petition.
Specifically, the suggested alternate test procedure will produce CEER
values for the variable-speed room air conditioners under the DOE test
procedure's existing rating condition that will more accurately reflect
the average performance improvement associated with variable-speed
compressors at differing operating conditions (i.e., optimization of
the refrigeration system efficiency through compressor speed
adjustments to better match the cooling load and eliminate cycling
losses), as compared to the performance changes that comparable single-
speed room air conditioners would experience under those same
conditions. Consequently, it appears likely that LG's petition for
waiver will be granted. Furthermore, DOE has determined that it is
desirable for public policy reasons to grant LG immediate relief
pending a determination of the petition for waiver.
---------------------------------------------------------------------------
\4\ DOE derived the specification for determining the
intermediate compressor speed from the DOE test procedure provisions
for central air conditioners with variable-speed compressors
(section 3.2.4.a of appendix M of 10 CFR part 430 subpart B).
---------------------------------------------------------------------------
For the reasons stated, DOE has granted an interim waiver to LG for
the specified room air conditioner basic models in LG's petition.
Therefore, DOE has issued an Order, stating:
(1) LG must test and rate the following room air conditioner basic
models with the alternate test procedure set forth in paragraph (2):
(A) LG LW2217IVSM, LG LW1817IVSM, and LG LW1517IVSM
(2) The alternate test procedure for the LG basic models listed in
subparagraph (1)(A) is the test procedure for room air conditioners
prescribed by DOE at appendix F to subpart B of 10 CFR part 430
(Appendix F), except the combined energy efficiency ratio (CEER) will
be determined as detailed below. All other requirements of Appendix F
and DOE's regulations remain applicable.
In Section 1, Definitions, add:
1.8 ``Single-speed'' means a type of room air conditioner that does
not automatically adjust either the compressor or fan speed, or both,
based on the detected outdoor conditions.
1.9 ``Variable-speed'' means a type of room air conditioner that
can automatically adjust compressor and fan speed, only compressor
speed, or only fan speed, based on the detected outdoor conditions.
Add to the end of Section 2.1 Cooling:
For a variable-speed room air conditioner, the cooling mode test
shall be repeated 3 additional times with alternate outdoor test
conditions, as described in section 3.1 of this appendix. For a
variable-speed room air conditioner, a psychrometric chamber may
alternatively be used in accordance with ANSI/ASHRAE Standard 37-2009
(incorporated by reference; see Sec. 430.3), in place of a calorimeter
chamber, which is required in accordance with appendix F. If using the
psychrometric chamber approach, set-up and instrument the variable-
speed room air conditioner in accordance with Section 5 and Section 6
of ANSI/ASHRAE Standard 37-2009, measure the indoor cooling capacity in
accordance with Section 7.3 of ANSI/ASHRAE Standard 37-2009, and
measure the average electrical input power in Watts at the nameplate
voltage for each of the rating test condition.
Add to the end of Section 3.1, Cooling mode:
However, for variable-speed room air conditioners, the set of four
cooling mode tests shall be conducted with the following test
conditions, presented in Table 1 of this appendix.

(3) Representations. LG may not make representations about the
energy efficiency of the basic models identified in paragraph (1) for
compliance, marketing, or other purposes unless the basic models have
been tested in accordance with the provisions in the alternate test
procedure and such representations fairly disclose the results of such
testing in accordance with 10 CFR 429.15(a).
(4) This interim waiver shall remain in effect according to the
provisions of 10 CFR 430.27.
(5) This interim waiver is issued to LG on the condition that the
statements, representations, and information provided by LG are valid.
DOE may revoke or modify this waiver at any time if it determines the
factual basis underlying the petition for waiver is incorrect, or the
results from the alternate test procedure are unrepresentative of the
basic models' true energy consumption characteristics. 10 CFR
430.27(k)(1). Likewise, LG may request that DOE rescind or modify the
interim waiver if LG discovers an error in the information provided to
DOE as part of its petition, determines that the interim waiver is no
longer needed, or for other appropriate reasons. 10 CFR 430.27(k)(2).
(6) Granting of this interim waiver does not release LG from the
certification requirements set forth at 10 CFR part 429.
DOE makes decisions on waivers and interim waivers for only those
basic models specifically set out in the petition, not future models
that may be manufactured by the petitioner. LG may submit a new or
amended petition for waiver and request for grant of interim waiver, as
appropriate, for additional basic models of room air conditioners.
Alternatively, if appropriate, LG may request that DOE extend the scope
of a waiver or an interim waiver to include additional basic models
employing the same technology as the basic models set forth in the
original petition consistent with 10 CFR 430.27(g).

In the Matter of:
Energy Efficiency Program: Test Procedure for Room Air Conditioners
Petition of LG Electronics, Inc. for Waiver and Application for Interim
Waiver of Test Procedure for Room Air Conditioners
LG Electronics, Inc. (LG) respectfully submits this Petition for
Waiver and Application for Interim Waiver \1\ from DOE's test procedure
for room air conditioners (RACs). LG seeks a waiver because the current
test procedure does not accurately measure the energy consumption of
RACs with variable speed compressors (VSCs). LG requests expedited
treatment of the Petition and Application.
---------------------------------------------------------------------------
\1\ See 10 C.F.R. Sec. 430.27 (petitions for waiver and interim
waiver).
---------------------------------------------------------------------------
LG is a manufacturer of room air conditioners and other products
sold worldwide, including in the United States. LG's United States
affiliate is LG Electronics USA, Inc., with headquarters at 1000 Sylvan
Avenue, Englewood Cliffs, NJ 07632 (tel. 201-816-2000). Its worldwide
headquarters are located at LG Twin Towers 20, Yoido-dong, Youngdungpo-
gu Seoul, Korea 150-721; (tel. 011-82-2-3777-1114); URL:
http.www.LGE.com.
I. Basic Models for Which a Waiver is Requested
The basic models for which a waiver is requested are set forth in
the Appendix. They are distributed in commerce under the LG brand name.
II. Need for the Requested Waiver
The LG RACs with VSC technology are advanced, energy efficient
products. A VSC (inverter compressor) uses frequency controls
constantly to adjust the compressor's rotation speed to maintain the
desired temperature in the home without turning the motor on and off.
The compressor responds automatically to surrounding conditions to
operate in the most efficient possible manner. This results in both
dramatic energy savings and faster cooling compared to products without
VSCs. RACs with VSCs also have a higher/lower operating range (10Hz to
120Hz) than those without VSC.\2\
---------------------------------------------------------------------------
\2\ To the best of LG's knowledge, LG is the only manufacturer
of RAC basic models distributed in commerce in the United States to
incorporate design characteristic(s) similar to those found in the
basic models that are the subject of this petition, namely, RAC VSC
technology.
---------------------------------------------------------------------------
Unfortunately, the current DOE test procedure for RACs provides
that they be tested only with full-load performance.\3\ Thus, the RAC
test procedure does not take into account the benefits of VSC, with its
part-load performance characteristics. This is unlike the DOE test
procedure for central air conditioners, which provides for testing with
part-load performance for VSCs.
---------------------------------------------------------------------------
\3\ 10 C.F.R. Part 430, Subpart B, Appendix F.
---------------------------------------------------------------------------
DOE has recognized this serious shortcoming in its RAC test
procedure. It has stated that this test procedure ``does not measure
the benefits of technologies that improve part-load performance.'' \4\
---------------------------------------------------------------------------
\4\ 80 Fed. Reg. 34843, 34848 (June 18, 2015).
The current room AC test procedure measures only the full-load
performance at outdoor ambient conditions of 95 [deg]F dry-bulb and
75 [deg]F wet-bulb. Therefore, technologies that improve part-load
performance, such as multiple-speed compressors and variable-opening
expansion devices, will not improve the rated performance of a room
AC under the current test procedure.'' \5\
---------------------------------------------------------------------------
\5\ Id.
Indeed, DOE has correctly stressed that, ``[i]n contrast, central ACs
and heat pumps are rated using multiple rating points at different
conditions.'' \6\ Finally, DOE has said it intends to investigate
potential revision of the test procedure ``to account for any benefits
of technologies that improve part-load performance.'' \7\
---------------------------------------------------------------------------
\6\ Id.
\7\ Id.
---------------------------------------------------------------------------
At the moment, however, the DOE test procedure for RACs does not
include any provision to account for the benefits of the part-load
performance of VSCs. Therefore, the test procedure evaluates the LG
models with VSCs in a manner that misrepresents their actual energy
consumption. LG urges that a waiver be granted, for the basic models in
the Appendix, that will allow use of the alternate test procedure
discussed below. The test procedure is designed to take into account
the energy savings characteristics of VSCs, and will yield results more
representative of the actual energy consumption of these products than
the current DOE test procedure. And the rules provide that DOE ``will
grant a waiver from the test procedure requirements'' in these
circumstances.\8\ The waiver should continue until DOE adopts an
applicable amended test procedure.
---------------------------------------------------------------------------
\8\ 10 C.F.R. Sec. 430.27(f)(2).
---------------------------------------------------------------------------
III. Proposed Alternate Test Procedure
LG proposes the following alternate test procedure to evaluate the
performance of the basic models listed in the Appendix. The alternate
test procedure is the same as the existing test procedure for RACs
except that it takes into account VSC part-load characteristics. It
does so by providing for tests at a variety of load conditions.
Specifically:
LG shall be required to test the performance of the basic models
listed in the Appendix hereto according to the test procedure for room
air conditioners in 10 C.F.R. Part 430, Subpart B, Appendix F, except
as follows:
Add new Sections 1.8 and 1.9 to Appendix F as follows:
``1.8 ``Single-speed'' means a type of room air conditioner that
does not automatically adjust either the compressor or fan speed, or
both, based on the detected outdoor conditions.
1.9 ``Variable-speed'' means a type of room air conditioner that
can automatically adjust compressor and fan speed, only compressor
speed, or only fan speed, based on the detected outdoor conditions.''
Add the following at the end of Section 2.1 of Appendix F:
``For a variable-speed room air conditioner, the cooling mode test
shall
[[Page 30724]]
be repeated 3 additional times with alternate outdoor test conditions,
as described in section 3.1 of this appendix. For a variable-speed room
air conditioner, a psychrometric chamber may alternatively be used in
place of a calorimeter chamber, in accordance with ANSI/ASHRAE Standard
37-2009 (incorporated by reference; see Sec. 430.3). If using the
psychrometric chamber approach, set-up and instrument the variable-
speed room air conditioner in accordance with Section 5 and Section 6
of ANSI/ASHRAE Standard 37-2009, measure the indoor cooling capacity in
accordance with Section 7.3 of ANSI/ASHRAE Standard 37-2009, and
measure the average electrical input power in Watts at the nameplate
voltage for each of the rating test condition.''
Add the following at the end of Section 3.1 of Appendix F:
``, except, for variable-speed room air conditioners, the set of
four cooling mode tests shall be conducted with the following test
conditions, presented in Table 1 of this appendix.

Test Condition 4............ 80 67 82 65 Minimum.
----------------------------------------------------------------------------------------------------------------
Add the following at the end of Section 4.1 of Appendix F:
``If using the psychrometric chamber approach for a variable-speed
room air conditioner, measure the indoor cooling capacity in accordance
with Section 7.3 of ANSI/ASHRAE Standard 37-2009 and measured power
input in cooling mode in accordance with Section 5.4 of ANSI/ASHRAE
Standard 37-2009.''
Add the following at the end of Section 5.1 of Appendix F:
``For variable-speed room air conditioners, determine cooling
capacity, Capacitym, for each of the four cooling mode
rating test conditions. The cooling capacity used in Sec. 430.23(f)
and reported in Sec. 429.15(b)(2) shall be the cooling capacity
determined for test condition 1 in Table 1 of this appendix.
Add the following at the end of Section 5.2 of Appendix F:
``For variable-speed room air conditioners, determine electrical
power input, Pm, for each of the four cooling mode rating
test conditions, and the electrical power input used in Sec. 430.23(f)
shall be the value measured for test condition 1 in Table 1 of this

IV. Application for Interim Waiver
LG also hereby applies for an interim waiver of the applicable test
procedure requirements for the LG basic models set forth in the
Appendix. LG meets the criteria for an interim waiver.
LG's Petition for Waiver is likely to be granted because the test
method contained in 10 C.F.R. Part 430, Subpart B, Appendix F clearly
does not address the VSC characteristics of these LG basic models.
Thus, the test procedure does not accurately measure their energy
consumption. Without waiver relief, LG would be subject to requirements
that are inapplicable to these products. Additionally, LG will suffer
economic hardship and be at a competitive disadvantage if it must wait
to rate these basic models pending a determination on the petition for
waiver.
DOE approval of LG's interim waiver application is also supported
by sound public policy. These LG products employ advanced technology
that increases efficiency and reduces energy consumption, while
offering a new level of affordable comfort to consumers.
V. Conclusion
LG respectfully requests that DOE grant its Petition for Waiver of
the applicable test procedure for specified basic models, and also
grant its Application for Interim Waiver.
LG requests expedited treatment of the Petition and Application.
Respectfully submitted,
Scott Harris/s/

Vice President, Compliance and General Counsel.
