Decision and Order
In the Matter of: LG Electronics, Inc.
(LG) (Case No. CAC–032).
Background
Title III, part C of the Energy Policy
and Conservation Act of 1975 (EPCA),
Public Law 94–163 (42 U.S.C. 6311–
6317, as codified, added by Public Law
95–619, Title IV, 441(a)) established the
Energy Conservation Program for
Certain Industrial Equipment, a program
covering commercial air conditioning
and heating equipment, which includes
the Multi V SYNC II and Multi V Water
II VRF multi-split heat pumps that are
the focus of this notice.1 Part C
specifically includes definitions (42
U.S.C. 6311), test procedures (42 U.S.C.
6314), labeling provisions (42 U.S.C.
6315), energy conservation standards
(42 U.S.C 6313), and the authority to
require information and reports from
manufacturers. 42 U.S.C. 6316. With
respect to test procedures, Part C
authorizes the Secretary of Energy (the
Secretary) to prescribe test procedures
that are reasonably designed to produce
results that measure energy efficiency,
energy use, and estimated annual
operating costs, and that are not unduly
burdensome to conduct. (42 U.S.C.
6314(a)(2))
For commercial package airconditioning and heating equipment,
1 For editorial reasons, upon codification in the
U.S. Code, part C was re-designated part A–1.

EPCA provides that ‘‘the test procedures
shall be those generally accepted
industry testing procedures or rating
procedures developed or recognized by
the Air-Conditioning and Refrigeration
Institute [ARI] or by the American
Society of Heating, Refrigerating and
Air-Conditioning Engineers [ASHRAE],
as referenced in ASHRAE/IES Standard
90.1 and in effect on June 30, 1992.’’ (42
U.S.C. 6314(a)(4)(A)) Under 42 U.S.C.
6314(a)(4)(B), the statute further directs
the Secretary to amend the test
procedure for covered commercial
equipment if the industry test procedure
is amended, unless the Secretary
determines, by rule and based on clear
and convincing evidence, that such a
modified test procedure does not meet
the statutory criteria set forth in 42
U.S.C. 6314(a)(2) and (3).
On December 8, 2006, DOE published
a final rule adopting test procedures for
commercial package air-conditioning
and heating equipment, effective
January 8, 2007. 71 FR 71340. Table 1
to Title 10 of the Code of Federal
Regulations (10 CFR) 431.96 directs
manufacturers of commercial package
air conditioning and heating equipment
to use the appropriate procedure when
measuring energy efficiency of this
equipment. For small commercial
packaged water-source heat pumps with
capacities less than 135,000 Btu/h, ISO
Standard 13256–1 (1998) is the
applicable test procedure. For
commercial package air-source
equipment with capacities between
65,000 and 760,000 Btu/h, ARI Standard
340/360–2004 is the applicable test
procedure.
DOE’s regulations for covered
products and equipment permit a
person to seek a waiver from the test
procedure requirements for covered
commercial equipment if at least one of
the following conditions is met: (1) The
petitioner’s basic model contains one or
more design characteristics that prevent
testing 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 as to
provide materially inaccurate
comparative data. 10 CFR 431.401(a)(1).
Petitioners must include in their
petition any alternate test procedures
known to the petitioner to evaluate the
basic model in a manner representative
of its energy consumption. 10 CFR
431.401(b)(1)(iii). The Assistant
Secretary for Energy Efficiency and
Renewable Energy (Assistant Secretary)
may grant a waiver subject to
conditions, including adherence to
alternate test procedures. 10 CFR
431.401(f)(4). Waivers remain in effect

tkelley on DSK3SPTVN1PROD with NOTICES
65708
Federal Register / Vol. 76, No. 205 / Monday, October 24, 2011 / Notices
pursuant to the provisions of 10 CFR
431.401(g).
The waiver process also permits
parties submitting a petition for waiver
to file an application for interim waiver
of the applicable test procedure
requirements. 10 CFR 431.401(a)(2). The
Assistant Secretary will grant an interim
waiver request if it is determined that
the applicant will experience economic
hardship if the application for interim
waiver is denied, if it appears likely that
the petition for waiver will be granted,
and/or the Assistant Secretary
determines that it would be desirable for
public policy reasons to grant
immediate relief pending a
determination on the petition for
waiver. 10 CFR 431.401(e)(3). An
interim waiver remains in effect for 180
days or until DOE issues its
determination on the petition for
waiver, whichever occurs first. It may be
extended by DOE for an additional 180
days. 10 CFR 431.401(e)(4).
On April 8, 2011, LG filed a petition
for waiver from the test procedure at 10
CFR 431.96 applicable to commercial
package air-source and water-source
central air conditioners and heat pumps,
as well as an application for interim
waiver. LG’s petition requested a waiver
for the LG Multi V SYNC II VRF multisplit air-source heat pumps with
capacities from 76,400 Btu/h to 310,000
Btu/h. The applicable test procedure for
these heat pumps is ARI 340/360–2004.
LG’s petition also requested a waiver for
its LG Multi V Water II water-source
heat pumps with capacities ranging
from 72,000 Btu/h to 95,900 Btu/h. The
applicable test procedure for these
products is ISO Standard 13256–1
(1998). Manufacturers are directed to
use these test procedures pursuant to
Table 1 of 10 CFR 431.96.
LG seeks a waiver from the applicable
test procedures under 10 CFR 431.96 on
the grounds that its Multi V SYNC II
and Multi V Water II VRF multi-split
commercial heat pumps contain design
characteristics that prevent testing
according to the current DOE test
procedures. Specifically, LG asserts that
the two primary factors that prevent
testing of this multi-split variable speed
equipment are the same factors stated in
the waivers that DOE has granted to
Mitsubishi Electric & Electronics USA,
Inc. (Mitsubishi) and other
manufacturers for similar lines of
commercial multi-split air-conditioning
systems:
• Testing laboratories cannot test
products with so many indoor units;
and
• There are too many possible
combinations of indoor and outdoor
units to test. See, e.g., 72 FR 17528
VerDate Mar<15>2010
15:34 Oct 21, 2011

(April 9, 2007) (Mitsubishi); 76 FR
19069 (April 6, 2011) (Daikin); 76 FR
19078 (April 6, 2011) (Mitsubishi).
On May 23, 2011, DOE published
LG’s petition for waiver in the Federal
Register, seeking public comment
pursuant to 10 CFR 431.401(b)(1)(iv),
and granted the application for interim
waiver. 76 FR 29733. DOE received no
comments on the LG petition.
Assertions and Determinations
LG’s Petition for Waiver
LG seeks a waiver from the applicable
DOE test procedures under 10 CFR
431.96 on the grounds that its Multi V
SYNC II and Multi V Water II VRF
multi-split commercial heat pumps
contain design characteristics that
prevent them from being tested using
the current DOE test procedures. As
stated above, LG asserts that the two
primary factors that prevent testing of
multi-split variable speed equipment are
the same factors that led DOE to grant
waivers to other manufacturers for
similar lines of commercial multi-split
heat pumps: (1) Testing laboratories
cannot test systems with so many
indoor units; and (2) there are too many
possible combinations of indoor and
outdoor units to test. For reasons similar
to those published in these prior
notices, DOE believes that an alternate
test procedure is appropriate in this
instance.
The Multi V SYNC II and Multi V
Water II heat pump systems consist of
multiple indoor units connected to an
air-cooled outdoor unit. These multisplit systems are used in zoned systems
where an outdoor or water-source unit
can be connected with up to 16 to 64
separate indoor units, which need not
be the same models. According to LG,
the various indoor and outdoor models
can be connected in a multitude of
configurations, with millions of possible
combinations. Consequently, LG
requested that DOE grant a waiver from
the applicable test procedures for its
Multi V SYNC II and Multi V Water II
VRF equipment designs until a suitable
test method can be prescribed.
After DOE granted a waiver for
Mitsubishi’s R22 multi-split equipment,
69 FR 52660 (Aug. 27, 2004), ARI
formed a committee to discuss testing
issues and to develop a testing protocol
for variable refrigerant flow systems.
The committee has developed a test
procedure which has been adopted by
the Air-Conditioning, Heating and
Refrigeration Institute (AHRI) and the
American National Standards Institute
(ANSI), ANSI/AHRI 1230—2010:
‘‘Performance Rating of Variable
Refrigerant Flow (VRF) Multi-Split Air-
PO 00000
Frm 00028
Fmt 4703
Sfmt 4703
Conditioning and Heat Pump
Equipment.’’ This test procedure has
been incorporated into ASHRAE 90.1—
2010. DOE is currently assessing ANSI/
AHRI 1230–2010 in light of the
requirements for test procedures
specified by EPCA (42 U.S.C.
6314(a)(4)(B)), and will provide a
preliminary determination regarding
those test procedures in a future notice
of proposed rulemaking.
LG’s petition proposed that DOE
apply the same alternate test procedure
DOE approved in the previous waiver
decisions to its Multi V SYNC II and
Multi V Water II VRF multi-split
commercial heat pumps as a condition
of its requested waiver. As stated above,
DOE has not received any comments
regarding the LG petition.
DOE issues today’s Decision and
Order granting LG a test procedure
waiver for its commercial Multi V SYNC
II and Multi V Water II VRF multi-split
commercial heat pumps. As a condition
of this waiver, LG must use the alternate
test procedure described below.
Alternate Test Procedure
The alternate test procedure
prescribed by DOE in previous multisplit commercial heat pump waivers,
including the interim waiver granted to
LG in response to the current petition,
consists of a definition of a ‘‘tested
combination’’ and a prescription for
representations. ANSI/AHRI 1230–2010
also includes a definition of ‘‘tested
combination,’’ and the two definitions
are identical in all relevant respects.
The alternate test procedure
prescribed by DOE in previous multisplit commercial heat pump waivers
provides for efficiency rating of a nontested combination in one of two ways:
(1) At an energy efficiency level
determined using a DOE-approved
alternative rating method or (2) at the
efficiency level of the tested
combination utilizing the same outdoor
unit. ANSI/AHRI 1230–2010 requires an
additional test and in this respect is
similar to the residential test procedure
set forth in 10 CFR part 430, subpart B,
appendix M. Under AHRI 1230, multisplit manufacturers must test two or
more combinations of indoor units with
each outdoor unit. The first system
combination is tested using only nonducted indoor units that meet the
definition of a tested combination. The
rating given to any untested multi-split
system combination having the same
outdoor unit and all non-ducted indoor
units is set equal to the rating of the
tested system having all non-ducted
indoor units. The second system
combination is tested using only ducted
indoor units that meet the definition of
E:\FR\FM\24OCN1.SGM
24OCN1
tkelley on DSK3SPTVN1PROD with NOTICES
Federal Register / Vol. 76, No. 205 / Monday, October 24, 2011 / Notices
a tested combination. The rating given
to any untested multi-split system
combination having the same outdoor
unit and all ducted indoor units is set
equal to the rating of the tested system
having all ducted indoor units. The
rating given to any untested multi-split
system combination having the same
outdoor unit and a mix of non-ducted
and ducted indoor units is set equal to
the average of the ratings for the two
required tested combinations.
With regard to the laboratory testing
of commercial equipment, some of the
difficulties associated with the existing
DOE test procedure are avoided through
the alternate test procedure’s
requirements for choosing the indoor
units to be used in the manufacturerspecified tested combination. For
example, in addition to limiting the
number of indoor units, another
requirement is that all the indoor units
must be subject to the same minimum
external static pressure. This
requirement enables the test laboratory
to manifold the outlets from each indoor
unit into a common plenum that
supplies air to a single airflow
measuring apparatus, thereby
eliminating situations in which some of
the indoor units are ducted and some
are non-ducted. Without this
requirement, the laboratory would have
to evaluate the capacity of a subgroup of
indoor coils separately and then sum
the separate capacities to obtain the
overall system capacity. Measuring
capacity in this way would require that
the test laboratory be equipped with
multiple airflow measuring apparatuses.
It is unlikely that any test laboratory
would be equipped with the necessary
number of such apparatuses.
Alternatively, the test laboratory could
connect its one airflow measuring
apparatus to one or more common
indoor units until the contribution of
each indoor unit had been measured.
However, that approach would be so
time-consuming as to be impractical.
For the reasons discussed above, DOE
believes LG’s Multi V SYNC II and
Multi V Water II VRF multi-split
commercial heat pumps cannot be
tested using the procedures prescribed
in 10 CFR 431.96. After careful
consideration, DOE has decided to
prescribe ANSI/AHRI 1230–2010 as the
alternate test procedure for LG’s
commercial multi-split products with
cooling capacities less than or equal to
300,000 Btu/hr (the maximum size
covered by ANSI/AHRI 1230–2010) and
the alternate test procedure specified in
LG’s interim waiver for its multi-split
commercial heat pumps with cooling
VerDate Mar<15>2010

Jkt 226001
capacity greater than 300,000 Btu/hr,2
except that tests of both ducted and
non-ducted indoor units must now be
conducted.
Consultations With Other Agencies
DOE consulted with the Federal Trade
Commission (FTC) staff concerning the
LG petition for waiver. The FTC staff
did not have any objections to issuing
a waiver to LG.
Conclusion
After careful consideration of all the
materials submitted by LG, the absence
of any comments, and consultation with
the FTC staff, it is ordered that:
(1) The petition for waiver filed by LG
(Case No. CAC–032) is hereby granted as
set forth in the paragraphs below.
(2) LG shall not be required to test or
rate its Multi V SYNC II and Multi V
Water II VRF multi-split commercial
heat pump models listed below
according to the test procedures cited in
10 CFR 431.96, which incorporates by
reference ARI 340/360–2004 for the
Multi V SYNC II air-source equipment
and ISO Standard 13256–1 (1998) for
the Multi V Water II water-source
equipment. Instead, LG shall be
required to test and rate such equipment
according to the alternate test procedure
as set forth in paragraph (3).

10 CFR 431.96, except that LG shall test
each model of outdoor unit with two or
more combinations of indoor units. The
first system combination shall be tested
using only non-ducted indoor units that
meet the definition of a tested
combination, as set forth in paragraph C.
The second system combination shall be
tested using only ducted indoor units
that meet the definition of a tested
combination, as set forth in paragraph C.
LG shall make representations
concerning the Multi V SYNC II and
Multi V Water II VRF multi-split heat
pump equipment covered in this waiver
according to the provisions of
subparagraph (D).
(C) Tested combination. The term
tested combination means a sample
basic model comprised of units that are
production units, or are representative
of production units, of the basic model
being tested. For the purposes of this
waiver, the tested combination shall
have the following features:
(1) The basic model of a variable
refrigerant flow system used as a tested
combination shall consist of one
outdoor unit, with one or more
compressors, that is matched with
between two and five indoor units. (For
systems with nominal cooling capacities
greater than 150,000 Btu/h, as many as
eight indoor units may be used, so as to
be able to test non-ducted indoor unit
combinations). For multi-split systems,
each of these indoor units shall be
designed for individual operation.
(2) The indoor units shall—
(i) Represent the highest sales model
family or another indoor model family
if the highest sales model family does
not provide sufficient capacity (see ii);
(ii) Together, have a nominal cooling
capacity that is between 95% and 105%
VerDate Mar<15>2010

Jkt 226001
of the nominal cooling capacity of the
outdoor unit;
(iii) Not, individually, have a nominal
cooling capacity that is greater than
50% of the nominal cooling capacity of
the outdoor unit;
(iv) Operate at fan speeds that are
consistent with the manufacturer’s
specifications; and
(v) Be subject to the same minimum
external static pressure requirement
while being configurable to produce the
same static pressure at the exit of each
outlet plenum when manifolded as per
section 2.4.1 of 10 CFR Part 430, subpart
B, appendix M.
(D) Representations. In making
representations about the energy
efficiency of its Multi V SYNC II and
Multi V Water II VRF multi-split
commercial heat pumps, for
compliance, marketing, or other
purposes, LG must fairly disclose the
results of testing under the DOE test
procedure in a manner consistent with
the provisions outlined below:
(i) For Multi V SYNC II and Multi V
Water II VRF multi-split combinations
tested in accordance with this alternate
test procedure, LG may make
representations based on those test
results.
(ii) For Multi V SYNC II and Multi V
Water II VRF multi-split combinations
that are not tested, LG may make
representations based on the testing
results for the tested combination and
that are consistent with one of the
following methods:
(a) Rating of non-tested combinations
according to an alternative rating
method approved by DOE.
(b) Rating of non-tested combinations
having the same outdoor unit and all
non-ducted indoor units shall be set
equal to the rating of the tested system
having all non-ducted indoor units.
(c) Rating of non-tested combinations
having the same outdoor unit and all
ducted indoor units shall be set equal to
the rating of the tested system having all
ducted indoor units. To be considered a
ducted unit, the indoor unit must be
intended to be connected with ductwork
and have a rated external static pressure
capability greater than zero (0).
(d) Rating of non-tested combinations
having the same outdoor unit and a mix
of non-ducted and ducted indoor units
shall be set equal to the average of the
ratings for the two required tested
combinations.
(4) This waiver shall remain in effect
from the date this Decision and Order is
issued, consistent with the provisions of
10 CFR 431.401(g).
(5) This waiver is issued on the
condition that the statements,
representations, and documentary
PO 00000
Frm 00030

materials provided by the petitioner are
valid. DOE may revoke or modify the
waiver at any time if it determines that
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.
(6) This waiver applies only to those
basic models set out in LG’s petition for
waiver.
(7) Grant of this waiver does not
release a petitioner from the
certification requirements set forth at 10
CFR part 429.

SUPPLEMENTARY INFORMATION: In accordance with Title 10 of the Code of
Federal Regulations (10 CFR) 431.401(f)(4), DOE is providing notice of
the issuance of the Decision and Order set forth below. In this
Decision and Order, DOE grants LG a waiver from the existing DOE
commercial package air conditioner and heat pump test procedures for
its Multi V SYNC II and Multi V Water II VRF multi-split commercial
equipment. The waiver requires LG to use the alternate test procedure
provided in this notice to test and rate the specified models of its
Multi V SYNC II and Multi V Water II VRF multi-split commercial
equipment line (as identified below).
Today's decision prohibits LG from making any representations
concerning the energy efficiency of this equipment unless the equipment
has been tested consistent with the provisions and restrictions in the
alternate test procedure set forth in the Decision and Order below, and
the representations fairly disclose the test results. (42 U.S.C.
6314(d)) Distributors, retailers, and private labelers are held to the

Decision and Order
In the Matter of: LG Electronics, Inc. (LG) (Case No. CAC-032).
Background
Title III, part C of the Energy Policy and Conservation Act of 1975
(EPCA), Public Law 94-163 (42 U.S.C. 6311-6317, as codified, added by
Public Law 95-619, Title IV, 441(a)) established the Energy
Conservation Program for Certain Industrial Equipment, a program
covering commercial air conditioning and heating equipment, which
includes the Multi V SYNC II and Multi V Water II VRF multi-split heat
pumps that are the focus of this notice.\1\ Part C specifically
includes definitions (42 U.S.C. 6311), test procedures (42 U.S.C.
6314), labeling provisions (42 U.S.C. 6315), energy conservation
standards (42 U.S.C 6313), and the authority to require information and
reports from manufacturers. 42 U.S.C. 6316. With respect to test
procedures, Part C authorizes the Secretary of Energy (the Secretary)
to prescribe test procedures that are reasonably designed to produce
results that measure energy efficiency, energy use, and estimated
annual operating costs, and that are not unduly burdensome to conduct.
(42 U.S.C. 6314(a)(2))
---------------------------------------------------------------------------
\1\ For editorial reasons, upon codification in the U.S. Code,
part C was re-designated part A-1.
---------------------------------------------------------------------------
For commercial package air-conditioning and heating equipment, EPCA
provides that ``the test procedures shall be those generally accepted
industry testing procedures or rating procedures developed or
recognized by the Air-Conditioning and Refrigeration Institute [ARI] or
by the American Society of Heating, Refrigerating and Air-Conditioning
Engineers [ASHRAE], as referenced in ASHRAE/IES Standard 90.1 and in
effect on June 30, 1992.'' (42 U.S.C. 6314(a)(4)(A)) Under 42 U.S.C.
6314(a)(4)(B), the statute further directs the Secretary to amend the
test procedure for covered commercial equipment if the industry test
procedure is amended, unless the Secretary determines, by rule and
based on clear and convincing evidence, that such a modified test
procedure does not meet the statutory criteria set forth in 42 U.S.C.
6314(a)(2) and (3).
On December 8, 2006, DOE published a final rule adopting test
procedures for commercial package air-conditioning and heating
equipment, effective January 8, 2007. 71 FR 71340. Table 1 to Title 10
of the Code of Federal Regulations (10 CFR) 431.96 directs
manufacturers of commercial package air conditioning and heating
equipment to use the appropriate procedure when measuring energy
efficiency of this equipment. For small commercial packaged water-
source heat pumps with capacities less than 135,000 Btu/h, ISO Standard
13256-1 (1998) is the applicable test procedure. For commercial package
air-source equipment with capacities between 65,000 and 760,000 Btu/h,
ARI Standard 340/360-2004 is the applicable test procedure.
DOE's regulations for covered products and equipment permit a
person to seek a waiver from the test procedure requirements for
covered commercial equipment if at least one of the following
conditions is met: (1) The petitioner's basic model contains one or
more design characteristics that prevent testing 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 as to provide materially inaccurate comparative
data. 10 CFR 431.401(a)(1). Petitioners must include in their petition
any alternate test procedures known to the petitioner to evaluate the
basic model in a manner representative of its energy consumption. 10
CFR 431.401(b)(1)(iii). The Assistant Secretary for Energy Efficiency
and Renewable Energy (Assistant Secretary) may grant a waiver subject
to conditions, including adherence to alternate test procedures. 10 CFR
431.401(f)(4). Waivers remain in effect
[[Page 65708]]
pursuant to the provisions of 10 CFR 431.401(g).
The waiver process also permits parties submitting a petition for
waiver to file an application for interim waiver of the applicable test
procedure requirements. 10 CFR 431.401(a)(2). The Assistant Secretary
will grant an interim waiver request if it is determined that the
applicant will experience economic hardship if the application for
interim waiver is denied, if it appears likely that the petition for
waiver will be granted, and/or the Assistant Secretary determines that
it would be desirable for public policy reasons to grant immediate
relief pending a determination on the petition for waiver. 10 CFR
431.401(e)(3). An interim waiver remains in effect for 180 days or
until DOE issues its determination on the petition for waiver,
whichever occurs first. It may be extended by DOE for an additional 180
days. 10 CFR 431.401(e)(4).
On April 8, 2011, LG filed a petition for waiver from the test
procedure at 10 CFR 431.96 applicable to commercial package air-source
and water-source central air conditioners and heat pumps, as well as an
application for interim waiver. LG's petition requested a waiver for
the LG Multi V SYNC II VRF multi-split air-source heat pumps with
capacities from 76,400 Btu/h to 310,000 Btu/h. The applicable test
procedure for these heat pumps is ARI 340/360-2004. LG's petition also
requested a waiver for its LG Multi V Water II water-source heat pumps
with capacities ranging from 72,000 Btu/h to 95,900 Btu/h. The
applicable test procedure for these products is ISO Standard 13256-1
(1998). Manufacturers are directed to use these test procedures
pursuant to Table 1 of 10 CFR 431.96.
LG seeks a waiver from the applicable test procedures under 10 CFR
431.96 on the grounds that its Multi V SYNC II and Multi V Water II VRF
multi-split commercial heat pumps contain design characteristics that
prevent testing according to the current DOE test procedures.
Specifically, LG asserts that the two primary factors that prevent
testing of this multi-split variable speed equipment are the same
factors stated in the waivers that DOE has granted to Mitsubishi
Electric & Electronics USA, Inc. (Mitsubishi) and other manufacturers
for similar lines of commercial multi-split air-conditioning systems:
Testing laboratories cannot test products with so many
indoor units; and
There are too many possible combinations of indoor and
outdoor units to test. See, e.g., 72 FR 17528 (April 9, 2007)
(Mitsubishi); 76 FR 19069 (April 6, 2011) (Daikin); 76 FR 19078 (April
6, 2011) (Mitsubishi).
On May 23, 2011, DOE published LG's petition for waiver in the
Federal Register, seeking public comment pursuant to 10 CFR
431.401(b)(1)(iv), and granted the application for interim waiver. 76
FR 29733. DOE received no comments on the LG petition.
Assertions and Determinations
LG's Petition for Waiver
LG seeks a waiver from the applicable DOE test procedures under 10
CFR 431.96 on the grounds that its Multi V SYNC II and Multi V Water II
VRF multi-split commercial heat pumps contain design characteristics
that prevent them from being tested using the current DOE test
procedures. As stated above, LG asserts that the two primary factors
that prevent testing of multi-split variable speed equipment are the
same factors that led DOE to grant waivers to other manufacturers for
similar lines of commercial multi-split heat pumps: (1) Testing
laboratories cannot test systems with so many indoor units; and (2)
there are too many possible combinations of indoor and outdoor units to
test. For reasons similar to those published in these prior notices,
DOE believes that an alternate test procedure is appropriate in this
instance.
The Multi V SYNC II and Multi V Water II heat pump systems consist
of multiple indoor units connected to an air-cooled outdoor unit. These
multi-split systems are used in zoned systems where an outdoor or
water-source unit can be connected with up to 16 to 64 separate indoor
units, which need not be the same models. According to LG, the various
indoor and outdoor models can be connected in a multitude of
configurations, with millions of possible combinations. Consequently,
LG requested that DOE grant a waiver from the applicable test
procedures for its Multi V SYNC II and Multi V Water II VRF equipment
designs until a suitable test method can be prescribed.
After DOE granted a waiver for Mitsubishi's R22 multi-split
equipment, 69 FR 52660 (Aug. 27, 2004), ARI formed a committee to
discuss testing issues and to develop a testing protocol for variable
refrigerant flow systems. The committee has developed a test procedure
which has been adopted by the Air-Conditioning, Heating and
Refrigeration Institute (AHRI) and the American National Standards
Institute (ANSI), ANSI/AHRI 1230--2010: ``Performance Rating of
Variable Refrigerant Flow (VRF) Multi-Split Air-Conditioning and Heat
Pump Equipment.'' This test procedure has been incorporated into ASHRAE
90.1--2010. DOE is currently assessing ANSI/AHRI 1230-2010 in light of
the requirements for test procedures specified by EPCA (42 U.S.C.
6314(a)(4)(B)), and will provide a preliminary determination regarding
those test procedures in a future notice of proposed rulemaking.
LG's petition proposed that DOE apply the same alternate test
procedure DOE approved in the previous waiver decisions to its Multi V
SYNC II and Multi V Water II VRF multi-split commercial heat pumps as a
condition of its requested waiver. As stated above, DOE has not
received any comments regarding the LG petition.
DOE issues today's Decision and Order granting LG a test procedure
waiver for its commercial Multi V SYNC II and Multi V Water II VRF
multi-split commercial heat pumps. As a condition of this waiver, LG
must use the alternate test procedure described below.
Alternate Test Procedure
The alternate test procedure prescribed by DOE in previous multi-
split commercial heat pump waivers, including the interim waiver
granted to LG in response to the current petition, consists of a
definition of a ``tested combination'' and a prescription for
representations. ANSI/AHRI 1230-2010 also includes a definition of
``tested combination,'' and the two definitions are identical in all
relevant respects.
The alternate test procedure prescribed by DOE in previous multi-
split commercial heat pump waivers provides for efficiency rating of a
non-tested combination in one of two ways: (1) At an energy efficiency
level determined using a DOE-approved alternative rating method or (2)
at the efficiency level of the tested combination utilizing the same
outdoor unit. ANSI/AHRI 1230-2010 requires an additional test and in
this respect is similar to the residential test procedure set forth in
10 CFR part 430, subpart B, appendix M. Under AHRI 1230, multi-split
manufacturers must test two or more combinations of indoor units with
each outdoor unit. The first system combination is tested using only
non-ducted indoor units that meet the definition of a tested
combination. The rating given to any untested multi-split system
combination having the same outdoor unit and all non-ducted indoor
units is set equal to the rating of the tested system having all non-
ducted indoor units. The second system combination is tested using only
ducted indoor units that meet the definition of
[[Page 65709]]
a tested combination. The rating given to any untested multi-split
system combination having the same outdoor unit and all ducted indoor
units is set equal to the rating of the tested system having all ducted
indoor units. The rating given to any untested multi-split system
combination having the same outdoor unit and a mix of non-ducted and
ducted indoor units is set equal to the average of the ratings for the
two required tested combinations.
With regard to the laboratory testing of commercial equipment, some
of the difficulties associated with the existing DOE test procedure are
avoided through the alternate test procedure's requirements for
choosing the indoor units to be used in the manufacturer-specified
tested combination. For example, in addition to limiting the number of
indoor units, another requirement is that all the indoor units must be
subject to the same minimum external static pressure. This requirement
enables the test laboratory to manifold the outlets from each indoor
unit into a common plenum that supplies air to a single airflow
measuring apparatus, thereby eliminating situations in which some of
the indoor units are ducted and some are non-ducted. Without this
requirement, the laboratory would have to evaluate the capacity of a
subgroup of indoor coils separately and then sum the separate
capacities to obtain the overall system capacity. Measuring capacity in
this way would require that the test laboratory be equipped with
multiple airflow measuring apparatuses. It is unlikely that any test
laboratory would be equipped with the necessary number of such
apparatuses. Alternatively, the test laboratory could connect its one
airflow measuring apparatus to one or more common indoor units until
the contribution of each indoor unit had been measured. However, that
approach would be so time-consuming as to be impractical.
For the reasons discussed above, DOE believes LG's Multi V SYNC II
and Multi V Water II VRF multi-split commercial heat pumps cannot be
tested using the procedures prescribed in 10 CFR 431.96. After careful
consideration, DOE has decided to prescribe ANSI/AHRI 1230-2010 as the
alternate test procedure for LG's commercial multi-split products with
cooling capacities less than or equal to 300,000 Btu/hr (the maximum
size covered by ANSI/AHRI 1230-2010) and the alternate test procedure
specified in LG's interim waiver for its multi-split commercial heat
pumps with cooling capacity greater than 300,000 Btu/hr,\2\ except that
tests of both ducted and non-ducted indoor units must now be conducted.
---------------------------------------------------------------------------
\2\ There is no technical justification for the 300,000 Btu/hr
limit, which was simply the largest multi-split capacity at the time
ANSI/AHRI 1230 was drafted.
---------------------------------------------------------------------------
Consultations With Other Agencies
DOE consulted with the Federal Trade Commission (FTC) staff
concerning the LG petition for waiver. The FTC staff did not have any
objections to issuing a waiver to LG.
Conclusion
After careful consideration of all the materials submitted by LG,
the absence of any comments, and consultation with the FTC staff, it is
ordered that:
(1) The petition for waiver filed by LG (Case No. CAC-032) is
hereby granted as set forth in the paragraphs below.
(2) LG shall not be required to test or rate its Multi V SYNC II
and Multi V Water II VRF multi-split commercial heat pump models listed
below according to the test procedures cited in 10 CFR 431.96, which
incorporates by reference ARI 340/360-2004 for the Multi V SYNC II air-
source equipment and ISO Standard 13256-1 (1998) for the Multi V Water
II water-source equipment. Instead, LG shall be required to test and
rate such equipment according to the alternate test procedure as set
forth in paragraph (3).

(3) Alternate test procedure.
(A) LG shall be required to test the equipment with cooling
capacities of 300,000 Btu/h and below listed in paragraph (2) above
according to the test procedure prescribed in ANSI/AHRI 1230-2010.
(B) LG shall be required to test the equipment listed in paragraph
(2) above with cooling capacities above 300,000 Btu/h according to the
test procedures for commercial central air conditioners and heat pumps
prescribed by DOE at 10 CFR 431.96, except that LG shall test each
model of outdoor unit with two or more combinations of indoor units.
The first system combination shall be tested using only non-ducted
indoor units that meet the definition of a tested combination, as set
forth in paragraph C. The second system combination shall be tested
using only ducted indoor units that meet the definition of a tested
combination, as set forth in paragraph C. LG shall make representations
concerning the Multi V SYNC II and Multi V Water II VRF multi-split
heat pump equipment covered in this waiver according to the provisions
of subparagraph (D).
(C) Tested combination. The term tested combination means a sample
basic model comprised of units that are production units, or are
representative of production units, of the basic model being tested.
For the purposes of this waiver, the tested combination shall have the
following features:
(1) The basic model of a variable refrigerant flow system used as a
tested combination shall consist of one outdoor unit, with one or more
compressors, that is matched with between two and five indoor units.
(For systems with nominal cooling capacities greater than 150,000 Btu/
h, as many as eight indoor units may be used, so as to be able to test
non-ducted indoor unit combinations). For multi-split systems, each of
these indoor units shall be designed for individual operation.
(2) The indoor units shall--
(i) Represent the highest sales model family or another indoor
model family if the highest sales model family does not provide
sufficient capacity (see ii);
(ii) Together, have a nominal cooling capacity that is between 95%
and 105% of the nominal cooling capacity of the outdoor unit;
(iii) Not, individually, have a nominal cooling capacity that is
greater than 50% of the nominal cooling capacity of the outdoor unit;
(iv) Operate at fan speeds that are consistent with the
manufacturer's specifications; and
(v) Be subject to the same minimum external static pressure
requirement while being configurable to produce the same static
pressure at the exit of each outlet plenum when manifolded as per
section 2.4.1 of 10 CFR Part 430, subpart B, appendix M.
(D) Representations. In making representations about the energy
efficiency of its Multi V SYNC II and Multi V Water II VRF multi-split
commercial heat pumps, for compliance, marketing, or other purposes, LG
must fairly disclose the results of testing under the DOE test
procedure in a manner consistent with the provisions outlined below:
(i) For Multi V SYNC II and Multi V Water II VRF multi-split
combinations tested in accordance with this alternate test procedure,
LG may make representations based on those test results.
(ii) For Multi V SYNC II and Multi V Water II VRF multi-split
combinations that are not tested, LG may make representations based on
the testing results for the tested combination and that are consistent
with one of the following methods:
(a) Rating of non-tested combinations according to an alternative
rating method approved by DOE.
(b) Rating of non-tested combinations having the same outdoor unit
and all non-ducted indoor units shall be set equal to the rating of the
tested system having all non-ducted indoor units.
(c) Rating of non-tested combinations having the same outdoor unit
and all ducted indoor units shall be set equal to the rating of the
tested system having all ducted indoor units. To be considered a ducted
unit, the indoor unit must be intended to be connected with ductwork
and have a rated external static pressure capability greater than zero
(0).
(d) Rating of non-tested combinations having the same outdoor unit
and a mix of non-ducted and ducted indoor units shall be set equal to
the average of the ratings for the two required tested combinations.
(4) This waiver shall remain in effect from the date this Decision
and Order is issued, consistent with the provisions of 10 CFR
431.401(g).
(5) This waiver is issued on the condition that the statements,
representations, and documentary materials provided by the petitioner
are valid. DOE may revoke or modify the waiver at any time if it
determines that 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.
(6) This waiver applies only to those basic models set out in LG's
petition for waiver.
(7) Grant of this waiver does not release a petitioner from the
certification requirements set forth at 10 CFR part 429.
Issued in Washington, DC, on October 18, 2011.

Deputy Assistant Secretary, Energy Efficiency and Renewable Energy.
