Energy Conservation Program: Petition for Waiver of LG 
Electronics USA, Inc. From the Department of Energy Portable 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 portable 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 
single-duct portable air conditioners does not take into account the 
benefits of portable air conditioners that use variable-speed 
compressors (``variable-speed portable air conditioners''), due to 
their part-load performance characteristics, and misrepresents their 
actual energy consumption. LG requests use of an alternate test 
procedure, under which the test unit's final combined energy efficiency 
ratio (``CEER'') metric would be calculated by multiplying the unit's 
measured CEER value (as measured according to the existing procedure 
for a single-duct portable air conditioner) by a ``performance 
adjustment factor.'' The performance adjustment factor would reflect 
the performance improvement associated with avoiding

[[Page 39275]]

cycling losses as a result of implementing a variable-speed compressor, 
when tested under the two rating conditions currently used for testing 
dual-duct portable air conditioners. DOE grants LG an interim waiver 
from DOE's portable air conditioner test procedure for the basic models 
listed in the interim waiver, 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 September 9, 2019.

SUPPLEMENTARY INFORMATION: 

I. Background and Authority

    The Energy Policy and Conservation Act of 1975, as amended 
(``EPCA''),\1\ among other things, authorizes DOE to regulate the 
energy efficiency of a number of consumer products and industrial 
equipment. (42 U.S.C. 6291-6317) Title III, Part B \2\ of EPCA 
established the Energy Conservation Program for Consumer Products Other 
Than Automobiles. In addition to specifying a list of covered products 
and industrial equipment, EPCA contains provisions that enable the 
Secretary of Energy to classify additional types of consumer products 
as covered products. (42 U.S.C. 6292(a)(20)) In a final determination 
of coverage published in the Federal Register on April 18, 2016 (the 
``April 2016 Final Coverage Determination''), DOE classified portable 
air conditioners as covered products under EPCA. 81 FR 22514. The test 
procedure for portable air conditioners is contained in the Code of 
Federal Regulations (``CFR'') at 10 CFR part 430, subpart B, appendix 
CC (``appendix CC'').
---------------------------------------------------------------------------

    \1\ All references to EPCA in this document refer to the statute 
as amended through America's Water Infrastructure Act of 2018, 
Public Law 115-270 (October 23, 2018).
    \2\ For editorial reasons, upon codification in the U.S. Code, 
Part B was re-designated Part A.
---------------------------------------------------------------------------

    Under 42 U.S.C. 6293, EPCA sets forth the criteria and procedures 
DOE is required to follow when prescribing or amending test procedures 
for covered products. EPCA requires that any test procedures prescribed 
or amended under this section must be reasonably designed to produce 
test results which reflect energy efficiency, energy use or estimated 
annual operating cost of a covered product during a representative 
average use cycle or period of use and requires that test procedures 
not be unduly burdensome to conduct. (42 U.S.C. 6293(b)(3))
    Under 10 CFR 430.27, any interested person may submit a petition 
for waiver from DOE's test procedure requirements. DOE will grant a 
waiver from the test procedure requirements if DOE determines either 
that the basic model for which the waiver was requested contains a 
design characteristic that prevents testing of the basic model 
according to the prescribed test procedures, or that the prescribed 
test procedures 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(f)(2). 
DOE may grant the waiver subject to conditions, including adherence to 
an alternate test procedure. Id.
    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 May 15, 2018, LG filed a petition for waiver and a petition for 
interim waiver from the test procedure for portable air conditioners, 
set forth in appendix CC. In the petition, LG requested relief for the 
following portable air conditioner basic models: LP1419IVSM, 
LP1419HVSM, LP1219IVSM, LP1019IVSM, and LP0819IVSM.\3\ LG notes that 
the current DOE test procedure for portable air conditioners requires 
testing dual-duct portable air conditioners under two operating 
conditions, one measuring peak-load performance (i.e., at a high-
temperature outdoor operating condition) and another measuring a 
reduced-load performance (i.e., at a lower outdoor temperature 
operating condition). For single-duct portable air conditioners, the 
test procedure requires testing at only the high-temperature outdoor 
operating condition. LG asserts that the current DOE test procedure for 
single-duct portable air conditioners does not take into account the 
specific performance and efficiency benefits associated with single-
duct variable-speed portable air conditioners under part-load 
conditions.
---------------------------------------------------------------------------

    \3\ LG provided these basic model numbers in its May 15, 2018 
petition.
---------------------------------------------------------------------------

    LG stated that single-duct variable-speed portable air conditioners 
constantly use frequency controls 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 significant energy savings and 
faster cooling compared to a portable air conditioner without a 
variable-speed compressor. LG asserted that, because the DOE test 
procedure does not account for the general part-load performance 
benefits of single-duct variable-speed portable air conditioners or 
properly account for the favorable difference in cycling losses for 
single-duct variable-speed portable air conditioners resulting from use 
of variable-speed technology, the results of the test procedure are not 
representative of the actual energy consumption of single-duct 
variable-speed portable air conditioners.
    LG also requested 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 single-duct 
variable-speed portable air conditioners, and without waiver relief, 
the test results would not reflect the part-load characteristics of the 
basic models listed above.

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 covered products. (42 U.S.C. 6293(c)) Consistent 
representations are important when making representations about the 
energy efficiency of products, including when demonstrating compliance 
with applicable DOE energy conservation standards. Pursuant to its 
regulations at 10 CFR 430.27, and after consideration of public 
comments on the petition, DOE may establish in a subsequent Decision 
and Order an alternate test procedure for the basic models addressed by 
the interim waiver.
    In its petition, LG requests testing the basic models listed in its 
petition according to the test procedure for portable air conditioners 
prescribed by DOE in appendix CC, except that single-duct variable-
speed portable air conditioners would be tested at both the high- and 
low-temperature outdoor operating conditions to measure a weighted-
average combined energy efficiency ratio (CEER). LG also suggests an 
additional set of calculations to model the CEER of a theoretical 
comparable single-speed portable air conditioner with and without 
cycling losses.\4\ From these results, a ``performance adjustment 
factor'' would be calculated, representing the performance improvement 
associated with avoiding cycling losses. The performance adjustment 
factor would then be multiplied by the measured CEER value for the 
variable-speed portable air conditioner according to appendix CC to 
determine the test unit's final rated CEER value. LG states that this 
approach takes into account performance and efficiency improvements 
associated with single-duct variable-speed portable air conditioners as 
compared to single-duct portable air conditioners with single-speed 
compressors.
---------------------------------------------------------------------------

    \4\ In its suggested alternate test procedure, LG included 
provisions regarding dual-duct variable-speed portable air 
conditioners. However, the basic models specified in LG's petition 
for waiver and petition for interim waiver are single-duct models 
only. As such, the alternate test procedure specified by DOE 
addresses only the single-duct variable-speed portable air 
conditioners listed by LG.
---------------------------------------------------------------------------

IV. Grant of an Interim Waiver

    DOE has reviewed the materials submitted in LG's petition. DOE has 
been unable to identify or review any marketing materials, website, or 
brochure for basic models LP1419IVSM, LP1419HVSM, LP1219IVSM, 
LP1019IVSM, and LP0819IVSM because they currently are not available in 
the U.S. market. The materials submitted support LG's assertion of the 
part-load characteristics of the single-duct variable-speed portable 
air conditioners and that the DOE test procedure may yield results that 
are unrepresentative of their true energy consumption characteristics. 
In particular, the DOE test procedure does not capture the relative 
efficiency improvements due to cycling loss avoidance that can be 
achieved by single-duct variable-speed portable air conditioners over a 
range of operating conditions compared to single-speed portable air 
conditioners. Without an alternate test procedure, the CEER values of 
single-duct variable-speed portable air conditioners would suggest that 
such portable air conditioners would consume at least as much energy 
annually as a theoretical comparable single-speed portable air 
conditioner, despite the anticipated benefits of improved performance 
under part-load conditions. DOE has reviewed the alternate procedure 
suggested by LG, along with additional performance modeling and 
analysis performed by DOE. Based on this review it appears that the 
suggested alternate test procedure will allow for the generally 
accurate measurement of efficiency of the specified basic models of 
single-duct variable-speed potable air conditioners, with certain 
additional requirements. First, the alternate test procedure provides 
compressor speed nomenclature and definitions that are derived from 
those in industry standards for testing consumer central air 
conditioning products with variable-speed compressors, with additional 
specificity for the low compressor speed definition that ensures the 
portable air conditioner provides adequate cooling capacity under 
reduced loads based on the expected load at those conditions.\5\

[[Page 39277]]

Second, LG must maintain the compressor speed required for each test 
condition in accordance with the instructions LG has provided to 
DOE.6 7
---------------------------------------------------------------------------

    \5\ The compressor speed nomenclature and definition 
clarifications are derived from Air-Conditioning, Heating, and 
Refrigeration Institute Standard (AHRI) 210/240-2017, ``Performance 
Rating of Unitary Air-conditioning & Air-source Heat Pump 
Equipment'', and adapted to be applicable to portable ACs. Equation 
11.60 in AHRI 210/240-2017 relates the building load to an AC's 
full-load cooling capacity and outdoor temperature, and assumes 
full-load operation at 98 [deg]F outdoor temperature. DOE adjusted 
(i.e. normalized) this equation to reflect full-load operation at 95 
[deg]F outdoor temperature, to provide consistency with the full-
load test condition for portable ACs. Using the adjusted equation 
suggests that the representative cooling load at the 83 [deg]F 
rating condition would be 60 percent of the full-load cooling 
capacity for portable air conditioners. DOE recognizes that 
variable-speed portable ACs may use compressors that vary their 
speed in discrete steps and may not be able to operate at a speed 
that provides exactly 60 percent cooling capacity; therefore, the 
defined cooling capacity associated with the low compressor speed is 
presented as a 10-percent range rather than a single value. 60 
percent cooling load is the upper bound of the 10-percent range 
defining the cooling capacity associated with the lower compressor 
speed (i.e., the range is defined as 50 to 60 percent). This ensures 
that the variable-speed portable AC is capable of matching the 
representative cooling load (60 percent of the maximum) at the 83 
[deg]F rating condition, while providing the performance benefits 
associated with variable-speed operation. In contrast, if the 10-
percent range were to be defined as, for example, 55 to 65 percent 
(with 60 percent as the midpoint), a variable-speed portable AC 
could be tested at 63 percent, for example, without demonstrating 
the capability to maintain variable-speed performance down to 60 
percent.
    \6\ Pursuant to 10 CFR 1004.11, if the manufacturer submits 
information that it believes to be confidential and exempt by law 
from public disclosure, the manufacturer should submit via email, 
postal mail, or hand delivery two well-marked copies: One copy of 
the document marked ``confidential'' including all the information 
believed to be confidential, and one copy of the document marked 
``non-confidential'' with the information believed to be 
confidential deleted. DOE will make its own determination about the 
confidential status of the information and treat it according to its 
determination.
    \7\ The instructions provided by LG were marked as confidential 
and, as such, the instructions will be treated as confidential. The 
document is located in the docket at https://www.regulations.gov/document?D=EERE-2018-BT-WAV-0007.
---------------------------------------------------------------------------

    Specifically, DOE has found that the suggested alternate test 
procedure will produce final CEER values for the single-duct variable-
speed portable air conditioners that will reflect the average 
performance improvement associated with variable-speed compressors as 
compared to theoretical comparable single-speed portable air 
conditioners under the same test 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 portable air conditioner basic models in LG's petition. 
Therefore, DOE has issued an Order stating:
    (1) LG must test the following portable air conditioner basic 
models with the alternate test procedure set forth in paragraph (2):

------------------------------------------------------------------------
                  Brand                             Basic model
------------------------------------------------------------------------
LG Electronics USA, Inc.................  LP1419IVSM
LG Electronics USA, Inc.................  LP1419HVSM
LG Electronics USA, Inc.................  LP1219IVSM
LG Electronics USA, Inc.................  LP1019IVSM
LG Electronics USA, Inc.................  LP0819IVSM
------------------------------------------------------------------------

    (2) The alternate test procedure for the LG basic models referenced 
in paragraph (1) is the test procedure for portable air conditioners 
prescribed by DOE at appendix CC to subpart B of 10 CFR part 430 
(Appendix CC), except: (i) Determine the combined energy efficiency 
ratio (CEER) as detailed below, and (ii) calculate the estimated annual 
operating cost in 10 CFR 430.23(dd)(2) as detailed below. In addition, 
for each basic model listed in paragraph (1), maintain the compressor 
speeds at each test condition, and set the control settings used for 
the variable components, according to the instructions submitted to DOE 
by LG. Upon the compliance date of any new energy conservation 
standards for portable air conditioners, LG must report product 
specific information pursuant to 10 CFR 429.12(b)(13) and 10 CFR 
429.62(b). All other requirements of Appendix CC and DOE's regulations 
remain applicable. In 10 CFR 430.23, in paragraph (dd) revise paragraph 
(2) to read as follows:
    (2) Determine the estimated annual operating cost for a single-duct 
variable-speed portable air conditioner, expressed in dollars per year, 
by multiplying the following two factors:
    (i) The sum of AEC95 multiplied by 0.2, AEC83 
multiplied by 0.8, and AECT as measured in accordance with 
section 5.3 of appendix CC of this subpart; and
    (ii) A representative average unit cost of electrical energy in 
dollars per kilowatt-hour as provided by the Secretary.
    (iii) Round the resulting product to the nearest dollar per year.
    In Appendix CC:
    Add in Section 2, Definitions:
    2.11 Single-speed means a type of portable air conditioner that 
cannot automatically adjust the compressor speed, based on detected 
conditions.
    2.12 Variable-speed means a type of portable air conditioner that 
can automatically adjust the compressor speed, based on detected 
conditions.
    2.13 Full compressor speed (full) means the compressor speed 
specified by the manufacturer at which the unit operates at full load 
testing conditions.
    2.14 Low compressor speed (low) means the compressor speed 
specified by the manufacturer at which the unit operates at low load 
test conditions, such that the measured cooling capacity at Condition B 
in Table 1 of this appendix, i.e., Capacity83, is not less 
than 50 percent and not greater than 60 percent of the measured cooling 
capacity with the full compressor speed at Condition A in Table 1 of 
this appendix, i.e., Capacity95.
    Add to the end of Section 3.1.2, Control settings:
    Set the compressor speed during cooling mode testing as described 
in section 4.1, as amended by this interim waiver.
    Replace Section 4.1, Cooling mode with the following:
    Cooling mode. Measure the indoor room cooling capacity and overall 
power input in cooling mode in accordance with Section 7.1.b and 7.1.c 
of ANSI/AHAM PAC-1-2015 (incorporated by reference; see Sec.  430.3), 
respectively. Determine the test duration in accordance with Section 
8.7 of ASHRAE Standard 37-2009 (incorporated by reference; Sec.  
430.3). Apply the test conditions presented in Table 1 of this appendix 
instead of the test conditions in Table 3 of ANSI/AHAM PAC-1-2015. 
Measure the indoor room cooling capacity and overall power input in 
accordance with ambient conditions for Test Configuration 3, Condition 
A (Capacity95, P95) in Table 1 of this appendix, 
with the compressor speed set to full, for the duration of cooling mode 
testing, and then measure the indoor room cooling capacity and overall 
power input a second time in accordance with the ambient conditions for 
Test Configuration 3, Condition B (Capacity83, 
P83) in Table 1 of this appendix, with the compressor speed 
set to low, for the duration of cooling mode testing. Set the 
compressor speed required for each test condition in accordance with 
instructions provided to DOE. Note that for the purposes of this 
cooling mode test procedure, evaporator inlet air is considered the 
``indoor air'' of the conditioned space and condenser inlet air is 
considered the ``outdoor air'' outside of the conditioned space.

    (3) Representations. LG may not make representations about the 
energy efficiency of the basic models listed in paragraph (1) for 
compliance, marketing, or other purposes unless the basic model has 
been tested in accordance with the provisions in this alternate test 
procedure and such representations fairly disclose the results of such 
testing.
    (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 a 
basic model's 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) LG remains obligated to fulfill any 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 portable 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 
Portable Air Conditioners

Petition of LG Electronics, Inc. for Waiver and Application for Interim 
Waiver of Test Procedure for Portable Air Conditioners

    LG Electronics, Inc. (LG) respectfully submits this Petition for 
Waiver and Application for Interim Waiver \1\ from DOE's test procedure 
for portable air conditioners (PACs). LG seeks a waiver because the 
current test procedure for PACs does not accurately measure the energy 
consumption of single-duct PACs with variable speed compressors (VSCs). 
LG requests expedited treatment of the Petition and Application.
---------------------------------------------------------------------------

    \1\ See 10 CFR 430.27 (petitions for waiver and interim waiver).
---------------------------------------------------------------------------

    LG is a manufacturer of PACs 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).

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 single-duct PACs distributed in commerce under 
the LG brand name.

II. Need for the Requested Waiver

    The LG PACs 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. PACs with VSCs also have a higher/lower operating range (10 Hz to 
120 Hz) than those without VSC.\2\
---------------------------------------------------------------------------

    \2\ To the best of LG's knowledge, LG is the only manufacturer 
of PAC 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, PAC VSC 
technology.
---------------------------------------------------------------------------

    Unfortunately, while the current DOE test procedure for dual-duct 
PACs provides that they be tested in two conditions, the test procedure 
provides for testing only with full-load performance for single-duct 
PACs.\3\ Thus, the PAC test procedure as applied to single-duct PACs 
does not take into account the benefits of VSC, with its part-load 
performance characteristics. This is also unlike the DOE test procedure 
for central air conditioners, which provides for testing with part-load 
performance for VSCs. Additionally, the PAC test procedure as applied 
to single-duct PACs does not properly account for the favorable 
difference in cycling losses resulting

[[Page 39283]]

from use of VSC technology. This technology limits the inefficiencies 
associated performance degradation from cycling losses. Cycling losses 
are avoided when the unit modulates its speed to meet a partial load 
rather than cycles on and off.
---------------------------------------------------------------------------

    \3\ 10 CFR Pt. 430, Subpart B, App. CC, Sec.  4.1, Tbl.1.
---------------------------------------------------------------------------

    DOE has recognized this serious shortcoming in the context of its 
test procedure for room air conditioners (RACs).\4\ It has stated that 
the RAC test procedure ``does not measure the benefits of technologies 
that improve part-load performance.'' \5\
---------------------------------------------------------------------------

    \4\ Id. App. F.
    \5\ 80 FR 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.\6\
---------------------------------------------------------------------------

    \6\ Id.

Indeed, DOE has correctly stressed that, ``[i]n contrast, central ACs 
and heat pumps are rated'' using ``multiple rating points at different 
conditions.'' \7\ 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.'' \8\ DOE is currently 
considering a waiver request by LG for RACs with VSCs.

    These considerations apply to single-duct PACs as well as dual-duct 
PACs and RACs. At the moment, however, the DOE test procedure for PACs 
as applied to single-duct PACs does not include any provision to 
account for the benefits of the part-load performance of VSCs or 
properly account for the favorable difference in cycling losses 
resulting from use of VSC technology. 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 alternate test procedure is designed to 
take into account the energy savings characteristics of VSCs, properly 
account for the favorable difference in cycling losses, and 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.\9\ 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 PACs 
except that it takes into account VSC part-load characteristics for 
single-duct PACs. It does so by providing for tests at multiple 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 
portable air conditioners in 10 CFR part 430, subpart B, Appendix CC, 
except as follows:
    Add new Section 2.10 to Appendix CC as follows:
    ``2.10 Single-speed means a type of portable air conditioner that 
does not automatically adjust either the compressor or fan speed, or 
both, based on the detected outdoor conditions.''
    Add new Section 2.12 to Appendix CC as follows:
    ``2.12 Variable-speed means a type of portable 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 3.1.2 of Appendix CC:
    ``For a variable-speed portable air conditioner, the compressor 
speed shall be set during cooling mode testing as described in section 
4.1 of this appendix.''
    Add the following at the end of Section 4.1 of Appendix CC:
    ``For a single-duct or dual-duct variable-speed portable air 
conditioner, measure the indoor room cooling capacity and overall power 
input in accordance with ambient conditions for Test Configuration 3, 
Condition A (Capacity95, P95) with the compressor 
speed set to maximum, and then measure the indoor room cooling capacity 
and overall power input a second time in accordance with the ambient 
conditions for Test Configuration 3, Condition B 
(Capacity83, P83) with the compressor speed set 
to minimum, for the duration of cooling mode testing.''
    Add in Section 4.1.1, Duct Heat Transfer following ``Calculate the 
total heat transferred from the surface of the duct(s) to the indoor 
conditioned space while operating in cooling mode for the outdoor test 
conditions in Table 1 of this appendix, as follows.'':
    ``Variable-speed portable air conditioners shall use the dual-duct 
portable air conditioner calculations.''
    Add in Section 4.1.2, Infiltration Air Heat Transfer after 
``Calculate the heat contribution from infiltration air for single-duct 
and dual-duct portable air conditioners for both cooling mode outdoor 
test conditions, as described in this section.:
    ``Variable-speed portable air conditioners shall use the dual-duct 
portable air conditioner calculations, except that the condenser inlet 
terms shall not be included for single-duct variable-speed portable air 
conditioners.''
    Add in Section 4.1.2, Infiltration Air Heat Transfer after 
``Calculate the dry air mass flow rate of infiltration air according to 
the following equations.'':
    ``For single-duct portable air conditioners:''
    Add in Section 5.1, Adjusted Cooling Capacity after ``Calculate the 
adjusted cooling capacities for portable air conditioners, 
ACC95 and ACC83, expressed in Btu/h, according to 
the following equations.'':
    ``Variable-speed portable air conditioners shall use the dual-duct 
portable air conditioner calculations.''
    Add in Section 5.3, Annual Energy Consumption after ``Calculate the 
annual energy consumption in each operating mode, AECm, 
expressed in kilowatt-hours per year (kWh/year).'':
    ``Variable-speed portable air conditioners shall use the dual-duct 
portable air conditioner annual operating hours and calculations.''
    Add in Section 5.4, Combined Energy Efficiency Ratio after 
``expressed in Btu/Wh,'':
    ``which shall be the combined energy efficiency ratio reported in 
Sec.  429.62(b)(2) for single-speed portable air conditioners,''
    Add the following after ``according to the following:'' in Section 
5.4 of Appendix CC:
    ``Variable-speed portable air conditioners shall use the dual-duct 
portable air conditioner calculation.''
    Add the following after Section 5.4 of Appendix CC:
    ``5.5 Adjustment of the Combined Energy Efficiency Ratio for 
Variable-Speed Portable Air Conditioners. Adjust the combined energy 
efficiency ratio for variable-speed portable air conditioners as 
follows, which shall be the combined energy efficiency ratio reported 
in Sec.  429.62(b)(2) for variable-speed portable air conditioners.

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 CFR part 430, subpart B, Appendix CC clearly 
does not address the VSC characteristics of these LG basic models and 
does not properly account for the favorable difference in cycling 
losses resulting from use of VSC technology. Thus, the test procedure 
does not accurately measure these models' 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,
