SUPPLEMENTARY INFORMATION: In
accordance with 10 CFR 431.401(f)(4),
DOE gives notice that it issues the
decision and order set forth below. In
this decision and order, DOE grants
Daikin a waiver from the existing DOE
commercial package air conditioner and
heat pump test procedures for its VRV–
III–C multi-split products. This waiver
requires Daikin use the alternate test
procedure provided in this notice to test
and rate the specified models from its
VRV–III–C multi-split product line. The
current test procedure is the AirConditioning and Refrigeration Institute
(ARI) Standard 340/360–2004,
‘‘Performance Rating of Commercial and
Industrial Unitary Air-Conditioning and
Heat Pump Equipment’’ (incorporated
by reference at 10 CFR 431.95(b)(2)).
Today’s decision prohibits Daikin
from making representations concerning
the energy efficiency of these products
unless the product 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 same
standard when making representations
regarding the energy efficiency of these
products. (42 U.S.C. 6293(c)).

Decision and Order
In the Matter of: Daikin AC
(Americas), Inc. (Daikin) (Case No.
CAC–025).
Background
Title III of the Energy Policy and
Conservation Act (EPCA) sets forth a
variety of provisions concerning energy
efficiency, including Part A of Title III,
which establishes the ‘‘Energy
Conservation Program for Consumer
Products Other Than Automobiles.’’ (42
U.S.C. 6291–6309) Part A–1 of Title III
E:\FR\FM\07MYN1.SGM
07MYN1
jlentini on DSKJ8SOYB1PROD with NOTICES
Federal Register / Vol. 75, No. 88 / Friday, May 7, 2010 / Notices
provides for a similar energy efficiency
program titled ‘‘Certain Industrial
Equipment,’’ which includes large and
small commercial air-conditioning
equipment, package boilers, storage
water heaters, and other types of
commercial equipment. (42 U.S.C.
6311–6317) EPCA specifically includes
definitions, test procedures, labeling
provisions, and energy conservation
standards for covered equipment. It also
provides DOE the authority to require
information and reports from
manufacturers. (42 U.S.C. 6311–6317)
With respect to test procedures, the
statute generally authorizes DOE to
prescribe test procedures that are
reasonably designed to produce test
results that reflect energy efficiency,
energy use, and estimated annual
operating costs, and that are not unduly
burdensome to conduct. (42 U.S.C.
6314(a)(2))
Today’s notice involves commercial
package air-conditioning and heating
equipment under Part A–1. EPCA
provides that for such equipment, ‘‘the
test procedures shall be those generally
accepted industry testing procedures or
rating procedures developed or
recognized by the Air-Conditioning and
Refrigeration Institute or by the
American Society of Heating,
Refrigerating and Air-Conditioning
Engineers, 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
Secretary of Energy (the Secretary) must
amend the test procedure for a covered
commercial product if the applicable
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. DOE
adopted Air-Conditioning and
Refrigeration Institute (ARI) Standard
210/240–2003 for small commercial
package air-cooled air-conditioning and
heating equipment with capacities
<65,000 British thermal units per hour
(Btu/h), and ARI Standard 340/360–
2004 for large and very large
commercial package air-cooled airconditioning and heating equipment
with capacities ≥ 65,000 Btu/h and
<760,000 Btu/h, respectively. Id. at
71371. Pursuant to the final rule, DOE’s
regulations at 10 CFR 431.95(b)(1)–(2)
incorporate by reference these two ARI
standards, and 10 CFR 431.96 directs
VerDate Mar<15>2010
19:19 May 06, 2010
Jkt 220001
manufacturers of commercial package
air-conditioning and heating equipment
to use the appropriate procedure when
measuring the energy efficiency of those
products. The cooling capacities of
Daikin’s VRV–III–C commercial multisplit products, which have capacities
between 72,000 Btu/hr and 192,000 Btu/
hr, fall in the range covered by ARI
Standard 340/360–2004.
In addition, DOE’s regulations for
covered equipment permit a person to
seek a waiver for a particular basic
model from the test procedure
requirements for covered commercial
equipment if (1) that basic model
contains one or more design
characteristics which 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
characteristics as to provide materially
inaccurate comparative data. 10 CFR
431.401(a)(1). Petitioner must include in
its waiver petition any alternate test
procedures known to the petitioner to
evaluate characteristics of 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 (the 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
pursuant to the provisions of 10 CFR
431.401(g).
The waiver process also allows any
interested person who has submitted a
petition for waiver to file an application
for interim waiver from the applicable
test procedure requirements. 10 CFR
431.401(a)(2). An interim waiver may be
granted if the Assistant Secretary
determines 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 if 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 September 9, 2009, Daikin filed a
petition for waiver and an application
for interim waiver from the test
procedures applicable to small and large
commercial package air-cooled airconditioning and heating equipment.

The applicable test procedure is ARI
340/360–2004, specified in Tables 1 and
2 of 10 CFR 431.96. Daikin asserted that
the two primary factors that prevent
testing of multi-split variable speed
products, regardless of manufacturer,
are the same factors stated in the
waivers that DOE granted to Mitsubishi
Electric & Electronics USA, Inc.
(Mitsubishi) for a similar line 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. Mitsubishi (72 FR 17528,
April 9, 2007); Samsung (72 FR 71387,
Dec. 17, 2007); Fujitsu (72 FR 71383,

April 10, 2009); and LG (74 FR 66330,
December 15, 2009).
On December 15, 2009, DOE
published Daikin’s petition for waiver
in the Federal Register, seeking public
comment pursuant to 431.3401(b)(1)(iv),
and granted the application for an
interim waiver. 74 FR 66324. DOE
received one comment on the Daikin
petition; discussion of and DOE’s
response to this comment are set forth
below.
In a similar case, DOE published a
petition for waiver from Mitsubishi
Electric and Electronics USA, Inc.
(MEUS), for products very similar to
Daikin’s multi-split products. 71 FR
14858 (March 24, 2006). In the March
24, 2006 Federal Register notice, DOE
also published and requested comment
on an alternate test procedure for the
MEUS products at issue. DOE stated
that if it specified an alternate test
procedure for MEUS in the subsequent
decision and order, DOE would
consider applying the same procedure
to similar waivers for residential and
commercial central air conditioners and
heat pumps, including such products
for which waivers had previously been
granted. Id. at 14861. Comments were
published along with the MEUS
decision and order in the Federal
Register on April 9, 2007. 72 FR 17528
(April 9, 2007). Most of the comments
were favorable. Though one commenter
indicated that a waiver was
unnecessary, the commenter did not
present a satisfactory way to test the
products. Id. at 17529. Generally,
commenters agreed that an alternate test
procedure is necessary while a final test
procedure for these types of products is
being developed. Id. The MEUS
decision and order included the

Assertions and Determinations
jlentini on DSKJ8SOYB1PROD with NOTICES
Daikin’s Petition for Waiver
Daikin seeks a waiver from the DOE
test procedures for this product class on
the grounds that its VRV–III–C multisplit heat pump and heat recovery
systems contain design characteristics
that prevent them from being tested
using the current DOE test procedures.
As stated above, Daikin asserts that
there are two primary factors that
prevent testing of multi-split variable
speed products, regardless of
manufacturer: Testing laboratories
cannot test products with so many
indoor units; there are too many
possible combinations of indoor and
outdoor units to test.
The VRV–III–C systems have
operational characteristics similar to
other commercial multi-split products
manufactured by Mitsubishi, Samsung,
Sanyo, Fujitsu and LG, all of which
have been granted waivers. The Daikin
VRV–III–C system can be connected to
the complete range of Daikin ceiling
mounted, concealed, ducted, corner,
cassette, wall-mounted and floormounted, and other indoor fan coil
units. Each of these units has nine
different standard indoor static pressure
ratings. Additional pressure ratings are
available. There are over 1,000,000
possible combinations of the VRV–III–C
products. Consequently, Daikin requests
that DOE grant a waiver from the
applicable test procedures for its VRV–
III–C product designs until a suitable
test method can be prescribed. DOE
believes that the Daikin VRV–III–C
equipment and equipment for which
waivers have previously been granted
are alike with respect to the factors that
make them eligible for test procedure
waivers. DOE therefore grants Daikin a
VRV–III–C multi-split product waiver
similar to the multi-split product
waivers already issued to other
manufacturers.
Previously, in addressing MEUS’s
R410A CITY MULTI VRFZ products,
which are similar to the Daikin products
at issue here, DOE stated:
To provide a test procedure from which
manufacturers can make valid
representations, the Department is
considering setting an alternate test
procedure for MEUS in the subsequent
decision and order. Furthermore, if DOE
specifies an alternate test procedure for
MEUS, DOE is considering applying the
alternate test procedure to similar waivers for
residential and commercial central air
conditioners and heat pumps. Such cases
include Samsung’s petition for its DVM
products (70 FR 9629, February 28, 2005),
VerDate Mar<15>2010
19:19 May 06, 2010
Jkt 220001
Fujitsu’s petition for its Airstage variable
refrigerant flow (VRF) products (70 FR 5980,
February 4, 2005), and MEUS’s petition for
its R22 CITY MULTI VRFZ products. (69 FR
52660, August 27, 2004).
71 FR 14861 (March 24, 2006).
In granting the petitions for waiver
from MEUS, DOE specified an alternate
test procedure that MEUS could use to
test, and make valid energy efficiency
representations for, its R410A CITY
MULTI products and its R22 multi-split
products. This alternate test procedure
was published in the Federal Register
on April 9, 2007 and on December 15,
2009. 72 FR 17528; 74 FR 66311. While
Daikin did not include an alternate test
procedure in its petition for waiver,
DOE believes that the same alternate test
procedure specified in the MEUS
decision could be used to test the Daikin
products at issue here.
DOE understands that existing testing
facilities have a limited ability to test
multiple indoor units at one time. It also
understands it is impractical to test
some variable refrigerant flow zoned
systems because of the number of
possible combinations of indoor and
outdoor units. DOE further notes that
after the waiver granted MEUS’s R22
multi-split products, AHRI formed a
committee to develop a testing protocol
for variable refrigerant flow systems.
The committee developed AHRI
Standard 1230–2009: ‘‘Performance
Rating of Variable Refrigerant Flow
(VRF) Multi-Split Air-Conditioning and
Heat Pump Equipment.’’ AHRI has
adopted the standard.
Carrier Corporation (Carrier)
commented that DOE should deny
Daikin’s petition for waiver and repeal
all the other commercial multi-split
waivers because of the availability of
AHRI 1230–2009. However, AHRI 1230–
2009, which is substantially the same as
DOE’s alternate test procedure with
respect to the testing of these Daikin
products, is not a part of DOE’s test
procedure. In addition, AHRI 1230–
2009 has not yet been adopted by
ASHRAE 90.1.
DOE issues today’s decision and order
granting Daikin a test procedure waiver
for its commercial VRV–III–C multi-split
heat pumps. As a condition of this
waiver, Daikin must use the alternate
test procedure described below. This
alternate test procedure is the same in
all relevant particulars as the procedure
specified in DOE’s decision and orders
granting the MEUS waivers.
Alternate Test Procedure
The alternate test procedure permits
Daikin to designate a tested combination
for each model of outdoor unit. The
indoor units designated as part of the
PO 00000
Frm 00042
Fmt 4703
Sfmt 4703
tested combination must meet specific
requirements. For example, the tested
combination must have between two to
eight indoor units so it can be tested in
available test facilities. The tested
combination was originally defined in
the MEUS waivers to consist of one
outdoor unit matched with between two
and five indoor units. The maximum
number of indoor units in a tested
combination is increased in this Daikin
waiver from five to eight because these
larger-capacity products can
accommodate more indoor units. The
tested combination must be tested
according to the applicable DOE test
procedure, as modified by the
provisions of the alternate test
procedure as set forth below.
The alternate DOE test procedure also
allows Daikin to represent the product’s
energy efficiency. These representations
must fairly disclose the test results. The
DOE test procedure, as modified by the
alternate test procedure set forth in this
decision and order, 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.
As in the MEUS waivers, DOE
believes that allowing Daikin to make
energy efficiency representations for
non-tested combinations by adopting
the alternative test procedure is
reasonable because the outdoor unit is
the principal efficiency driver. The
current DOE test procedure for
commercial products tends to rate these
products conservatively because it does
not account for their multi-zoning
feature. The multi-zoning feature
enables these products to cool only
those portions of the building that
require cooling. Products with a multizoning feature would be expected to use
less energy than units controlled by a
single thermostat, which cool the entire
home or commercial building regardless
of whether only portions need cooling.
The multi-zoning feature would not be
properly evaluated by the current test
procedure, which requires full-load
testing. Full load testing requires the
entire building to be cooled. Products
using a multi-zoning feature and
subjected to full load testing would be
at a disadvantage because they are
optimized for highest efficiency when
operating with less than full loads. The
alternate test procedure will provide an
appropriate basis for assessing the
energy efficiency of such products.
With regard to the laboratory testing
of commercial products, some of the
difficulties associated with the existing
E:\FR\FM\07MYN1.SGM
07MYN1
25227
Federal Register / Vol. 75, No. 88 / Friday, May 7, 2010 / Notices
test procedure are avoided by 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 subjected to the
same minimum external static pressure.
This requirement enables the test lab to
manifold the outlets from each indoor
unit into a common plenum that
supplies air to a single airflow
measuring apparatus. This eliminates
situations in which some of the indoor
units are ducted and some are nonducted. Without this requirement, the
laboratory must 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, which would be so
time-consuming as to be impractical.
For the reasons discussed above, DOE
believes Daikin’s VRV–III–C multi-split
products cannot be tested using the
procedure prescribed in 10 CFR 431.96
(ARI Standard 340/360–2004) and
incorporated by reference in DOE’s
regulations at 10 CFR 431.95(b)(2). After
careful consideration, DOE has decided
to prescribe the alternate test procedure
first developed for the MEUS waiver for
Daikin’s commercial multi-split
products. The alternate test procedure
for the Daikin products must include
the modifications described above.
Consultations With Other Agencies
DOE consulted with the Federal Trade
Commission (FTC) staff concerning the
Daikin petition for waiver. The FTC staff
did not have any objections to issuing
a waiver to Daikin.
Conclusion
After careful consideration of all the
materials submitted by Daikin, the
absence of any comments, and
consultation with the FTC staff, it is
ordered that:
(1) The petition for waiver filed by
Daikin Electronics, Inc., (Daikin) (Case
No. CAC–025) is hereby granted as set
forth in the paragraphs below.
(2) Daikin shall not be required to test
or rate its VRV–III–C multi-split air
conditioner and heat pump models
listed below on the basis of the test
procedure cited in 10 CFR 431.96,
specifically, ARI Standard 340/360–
2004 (incorporated by reference in 10
CFR 431.95(b)(2)), but shall be required
to test and rate such products according
to the alternate test procedure as set
forth in paragraph (3).

SUMMARY: This notice publishes the U.S. Department of Energy's (DOE)
decision and order in Case No. CAC-025, which grants a waiver to Daikin
from the existing DOE test procedure applicable to commercial package
central air conditioners and heat pumps. The waiver is specific to the
Daikin variable speed and variable refrigerant volume VRV-III-C
(commercial) multi-split heat pumps and heat recovery systems. As a
condition of this waiver, Daikin must use the alternate test procedure
set forth in this notice to test and rate its VRV-III-C multi-split
products.

SUPPLEMENTARY INFORMATION: In accordance with 10 CFR 431.401(f)(4), DOE
gives notice that it issues the decision and order set forth below. In
this decision and order, DOE grants Daikin a waiver from the existing
DOE commercial package air conditioner and heat pump test procedures
for its VRV-III-C multi-split products. This waiver requires Daikin use
the alternate test procedure provided in this notice to test and rate
the specified models from its VRV-III-C multi-split product line. The
current test procedure is the Air-Conditioning and Refrigeration
Institute (ARI) Standard 340/360-2004, ``Performance Rating of
Commercial and Industrial Unitary Air-Conditioning and Heat Pump
Equipment'' (incorporated by reference at 10 CFR 431.95(b)(2)).
Today's decision prohibits Daikin from making representations
concerning the energy efficiency of these products unless the product
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
same standard when making representations regarding the energy
efficiency of these products. (42 U.S.C. 6293(c)).
Issued in Washington, DC, on April 30, 2010.

Assistant Secretary, Energy Efficiency and Renewable Energy.
Decision and Order
In the Matter of: Daikin AC (Americas), Inc. (Daikin) (Case No.
CAC-025).
Background
Title III of the Energy Policy and Conservation Act (EPCA) sets
forth a variety of provisions concerning energy efficiency, including
Part A of Title III, which establishes the ``Energy Conservation
Program for Consumer Products Other Than Automobiles.'' (42 U.S.C.
6291-6309) Part A-1 of Title III
[[Page 25225]]
provides for a similar energy efficiency program titled ``Certain
Industrial Equipment,'' which includes large and small commercial air-
conditioning equipment, package boilers, storage water heaters, and
other types of commercial equipment. (42 U.S.C. 6311-6317) EPCA
specifically includes definitions, test procedures, labeling
provisions, and energy conservation standards for covered equipment. It
also provides DOE the authority to require information and reports from
manufacturers. (42 U.S.C. 6311-6317) With respect to test procedures,
the statute generally authorizes DOE to prescribe test procedures that
are reasonably designed to produce test results that reflect energy
efficiency, energy use, and estimated annual operating costs, and that
are not unduly burdensome to conduct. (42 U.S.C. 6314(a)(2))
Today's notice involves commercial package air-conditioning and
heating equipment under Part A-1. EPCA provides that for such
equipment, ``the test procedures shall be those generally accepted
industry testing procedures or rating procedures developed or
recognized by the Air-Conditioning and Refrigeration Institute or by
the American Society of Heating, Refrigerating and Air-Conditioning
Engineers, 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 Secretary of Energy (the Secretary) must amend the
test procedure for a covered commercial product if the applicable
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. DOE adopted Air-
Conditioning and Refrigeration Institute (ARI) Standard 210/240-2003
for small commercial package air-cooled air-conditioning and heating
equipment with capacities <65,000 British thermal units per hour (Btu/
h), and ARI Standard 340/360-2004 for large and very large commercial
package air-cooled air-conditioning and heating equipment with
capacities >= 65,000 Btu/h and <760,000 Btu/h, respectively. Id. at
71371. Pursuant to the final rule, DOE's regulations at 10 CFR
431.95(b)(1)-(2) incorporate by reference these two ARI standards, and
10 CFR 431.96 directs manufacturers of commercial package air-
conditioning and heating equipment to use the appropriate procedure
when measuring the energy efficiency of those products. The cooling
capacities of Daikin's VRV-III-C commercial multi-split products, which
have capacities between 72,000 Btu/hr and 192,000 Btu/hr, fall in the
range covered by ARI Standard 340/360-2004.
In addition, DOE's regulations for covered equipment permit a
person to seek a waiver for a particular basic model from the test
procedure requirements for covered commercial equipment if (1) that
basic model contains one or more design characteristics which 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 characteristics as to
provide materially inaccurate comparative data. 10 CFR 431.401(a)(1).
Petitioner must include in its waiver petition any alternate test
procedures known to the petitioner to evaluate characteristics of 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 (the 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 pursuant to
the provisions of 10 CFR 431.401(g).
The waiver process also allows any interested person who has
submitted a petition for waiver to file an application for interim
waiver from the applicable test procedure requirements. 10 CFR
431.401(a)(2). An interim waiver may be granted if the Assistant
Secretary determines 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 if 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 September 9, 2009, Daikin filed a petition for waiver and an
application for interim waiver from the test procedures applicable to
small and large commercial package air-cooled air-conditioning and
heating equipment. The applicable test procedure is ARI 340/360-2004,
specified in Tables 1 and 2 of 10 CFR 431.96. Daikin asserted that the
two primary factors that prevent testing of multi-split variable speed
products, regardless of manufacturer, are the same factors stated in
the waivers that DOE granted to Mitsubishi Electric & Electronics USA,
Inc. (Mitsubishi) for a similar line 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. Mitsubishi (72 FR 17528, April 9, 2007); Samsung
(72 FR 71387, Dec. 17, 2007); Fujitsu (72 FR 71383, Dec. 17, 2007);
Daikin (73 FR 39680, July 10, 2008); Daikin (74 FR 15955, April 8,

10, 2009); and LG (74 FR 66330, December 15, 2009).
On December 15, 2009, DOE published Daikin's petition for waiver in
the Federal Register, seeking public comment pursuant to
431.3401(b)(1)(iv), and granted the application for an interim waiver.
74 FR 66324. DOE received one comment on the Daikin petition;
discussion of and DOE's response to this comment are set forth below.
In a similar case, DOE published a petition for waiver from
Mitsubishi Electric and Electronics USA, Inc. (MEUS), for products very
similar to Daikin's multi-split products. 71 FR 14858 (March 24, 2006).
In the March 24, 2006 Federal Register notice, DOE also published and
requested comment on an alternate test procedure for the MEUS products
at issue. DOE stated that if it specified an alternate test procedure
for MEUS in the subsequent decision and order, DOE would consider
applying the same procedure to similar waivers for residential and
commercial central air conditioners and heat pumps, including such
products for which waivers had previously been granted. Id. at 14861.
Comments were published along with the MEUS decision and order in the
Federal Register on April 9, 2007. 72 FR 17528 (April 9, 2007). Most of
the comments were favorable. Though one commenter indicated that a
waiver was unnecessary, the commenter did not present a satisfactory
way to test the products. Id. at 17529. Generally, commenters agreed
that an alternate test procedure is necessary while a final test
procedure for these types of products is being developed. Id. The MEUS
decision and order included the
[[Page 25226]]
alternate test procedure adopted by DOE. Id.
Assertions and Determinations
Daikin's Petition for Waiver
Daikin seeks a waiver from the DOE test procedures for this product
class on the grounds that its VRV-III-C multi-split heat pump and heat
recovery systems contain design characteristics that prevent them from
being tested using the current DOE test procedures. As stated above,
Daikin asserts that there are two primary factors that prevent testing
of multi-split variable speed products, regardless of manufacturer:
Testing laboratories cannot test products with so many indoor units;
there are too many possible combinations of indoor and outdoor units to
test.
The VRV-III-C systems have operational characteristics similar to
other commercial multi-split products manufactured by Mitsubishi,
Samsung, Sanyo, Fujitsu and LG, all of which have been granted waivers.
The Daikin VRV-III-C system can be connected to the complete range of
Daikin ceiling mounted, concealed, ducted, corner, cassette, wall-
mounted and floor-mounted, and other indoor fan coil units. Each of
these units has nine different standard indoor static pressure ratings.
Additional pressure ratings are available. There are over 1,000,000
possible combinations of the VRV-III-C products. Consequently, Daikin
requests that DOE grant a waiver from the applicable test procedures
for its VRV-III-C product designs until a suitable test method can be
prescribed. DOE believes that the Daikin VRV-III-C equipment and
equipment for which waivers have previously been granted are alike with
respect to the factors that make them eligible for test procedure
waivers. DOE therefore grants Daikin a VRV-III-C multi-split product
waiver similar to the multi-split product waivers already issued to
other manufacturers.
Previously, in addressing MEUS's R410A CITY MULTI VRFZ products,
which are similar to the Daikin products at issue here, DOE stated:
To provide a test procedure from which manufacturers can make
valid representations, the Department is considering setting an
alternate test procedure for MEUS in the subsequent decision and
order. Furthermore, if DOE specifies an alternate test procedure for
MEUS, DOE is considering applying the alternate test procedure to
similar waivers for residential and commercial central air
conditioners and heat pumps. Such cases include Samsung's petition
for its DVM products (70 FR 9629, February 28, 2005), Fujitsu's
petition for its Airstage variable refrigerant flow (VRF) products
(70 FR 5980, February 4, 2005), and MEUS's petition for its R22 CITY
MULTI VRFZ products. (69 FR 52660, August 27, 2004).
71 FR 14861 (March 24, 2006).
In granting the petitions for waiver from MEUS, DOE specified an
alternate test procedure that MEUS could use to test, and make valid
energy efficiency representations for, its R410A CITY MULTI products
and its R22 multi-split products. This alternate test procedure was
published in the Federal Register on April 9, 2007 and on December 15,
2009. 72 FR 17528; 74 FR 66311. While Daikin did not include an
alternate test procedure in its petition for waiver, DOE believes that
the same alternate test procedure specified in the MEUS decision could
be used to test the Daikin products at issue here.
DOE understands that existing testing facilities have a limited
ability to test multiple indoor units at one time. It also understands
it is impractical to test some variable refrigerant flow zoned systems
because of the number of possible combinations of indoor and outdoor
units. DOE further notes that after the waiver granted MEUS's R22
multi-split products, AHRI formed a committee to develop a testing
protocol for variable refrigerant flow systems. The committee developed
AHRI Standard 1230-2009: ``Performance Rating of Variable Refrigerant
Flow (VRF) Multi-Split Air-Conditioning and Heat Pump Equipment.'' AHRI
has adopted the standard.
Carrier Corporation (Carrier) commented that DOE should deny
Daikin's petition for waiver and repeal all the other commercial multi-
split waivers because of the availability of AHRI 1230-2009. However,
AHRI 1230-2009, which is substantially the same as DOE's alternate test
procedure with respect to the testing of these Daikin products, is not
a part of DOE's test procedure. In addition, AHRI 1230-2009 has not yet
been adopted by ASHRAE 90.1.
DOE issues today's decision and order granting Daikin a test
procedure waiver for its commercial VRV-III-C multi-split heat pumps.
As a condition of this waiver, Daikin must use the alternate test
procedure described below. This alternate test procedure is the same in
all relevant particulars as the procedure specified in DOE's decision
and orders granting the MEUS waivers.
Alternate Test Procedure
The alternate test procedure permits Daikin to designate a tested
combination for each model of outdoor unit. The indoor units designated
as part of the tested combination must meet specific requirements. For
example, the tested combination must have between two to eight indoor
units so it can be tested in available test facilities. The tested
combination was originally defined in the MEUS waivers to consist of
one outdoor unit matched with between two and five indoor units. The
maximum number of indoor units in a tested combination is increased in
this Daikin waiver from five to eight because these larger-capacity
products can accommodate more indoor units. The tested combination must
be tested according to the applicable DOE test procedure, as modified
by the provisions of the alternate test procedure as set forth below.
The alternate DOE test procedure also allows Daikin to represent
the product's energy efficiency. These representations must fairly
disclose the test results. The DOE test procedure, as modified by the
alternate test procedure set forth in this decision and order, 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.
As in the MEUS waivers, DOE believes that allowing Daikin to make
energy efficiency representations for non-tested combinations by
adopting the alternative test procedure is reasonable because the
outdoor unit is the principal efficiency driver. The current DOE test
procedure for commercial products tends to rate these products
conservatively because it does not account for their multi-zoning
feature. The multi-zoning feature enables these products to cool only
those portions of the building that require cooling. Products with a
multi-zoning feature would be expected to use less energy than units
controlled by a single thermostat, which cool the entire home or
commercial building regardless of whether only portions need cooling.
The multi-zoning feature would not be properly evaluated by the current
test procedure, which requires full-load testing. Full load testing
requires the entire building to be cooled. Products using a multi-
zoning feature and subjected to full load testing would be at a
disadvantage because they are optimized for highest efficiency when
operating with less than full loads. The alternate test procedure will
provide an appropriate basis for assessing the energy efficiency of
such products.
With regard to the laboratory testing of commercial products, some
of the difficulties associated with the existing
[[Page 25227]]
test procedure are avoided by 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 subjected to the same minimum external static
pressure. This requirement enables the test lab to manifold the outlets
from each indoor unit into a common plenum that supplies air to a
single airflow measuring apparatus. This eliminates situations in which
some of the indoor units are ducted and some are non-ducted. Without
this requirement, the laboratory must 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, which would be
so time-consuming as to be impractical.
For the reasons discussed above, DOE believes Daikin's VRV-III-C
multi-split products cannot be tested using the procedure prescribed in
10 CFR 431.96 (ARI Standard 340/360-2004) and incorporated by reference
in DOE's regulations at 10 CFR 431.95(b)(2). After careful
consideration, DOE has decided to prescribe the alternate test
procedure first developed for the MEUS waiver for Daikin's commercial
multi-split products. The alternate test procedure for the Daikin
products must include the modifications described above.
Consultations With Other Agencies
DOE consulted with the Federal Trade Commission (FTC) staff
concerning the Daikin petition for waiver. The FTC staff did not have
any objections to issuing a waiver to Daikin.
Conclusion
After careful consideration of all the materials submitted by
Daikin, the absence of any comments, and consultation with the FTC
staff, it is ordered that:
(1) The petition for waiver filed by Daikin Electronics, Inc.,
(Daikin) (Case No. CAC-025) is hereby granted as set forth in the
paragraphs below.
(2) Daikin shall not be required to test or rate its VRV-III-C
multi-split air conditioner and heat pump models listed below on the
basis of the test procedure cited in 10 CFR 431.96, specifically, ARI
Standard 340/360-2004 (incorporated by reference in 10 CFR
431.95(b)(2)), but shall be required to test and rate such products
according to the alternate test procedure as set forth in paragraph
(3).

(3) Alternate test procedure.
(A) Daikin is required to test the products listed in paragraph (2)
above according to the test procedure for central air conditioners and
heat pumps prescribed by DOE at 10 CFR Part 431 (ARI 340/360-2004,
(incorporated by reference in 10 CFR 431.95(b)(2)), except that Daikin
shall test a tested combination selected in accordance with the
provisions of subparagraph (B) of this paragraph. For every other
system combination using the same outdoor unit as the tested
combination, Daikin shall make representations concerning the VRV-III-C
products covered in this waiver according to the provisions of
subparagraph (C) below.
(B) 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:
(i) The basic model of a variable refrigerant flow system used as a
tested combination shall consist of an outdoor unit that is matched
with between two and eight indoor units. For multi-split systems, each
of these indoor units shall be designed for individual operation.
(ii) The indoor units shall:
(a) Represent the highest sales model family, or another indoor
model family if the highest sales model family does not provide
sufficient capacity (see b);
(b) Together, have a nominal cooling capacity that is between 95
percent and 105 percent of the nominal cooling capacity of the outdoor
unit;
(c) Not, individually, have a nominal cooling capacity greater than
50 percent of the nominal cooling capacity of the outdoor unit;
(d) Operate at fan speeds that are consistent with the
manufacturer's specifications; and
(e) Be subject to the same minimum external static pressure
requirement.
(C) Representations. In making representations about the energy
efficiency of its VRV-III-C multi-split products for compliance,
marketing, or other purposes, Daikin must fairly disclose the results
of testing under the DOE test procedure in a manner consistent with the
provisions outlined below:
(i) For VRV-III-C multi-split combinations tested in accordance
with this alternate test procedure, Daikin may make representations
based on these test results.
(ii) For VRV-III-C multi-split combinations that are not tested,
Daikin may make representations based on the testing results for the
tested combination and that are consistent with either of the two
following methods:
(a) Representation of non-tested combinations according to an
alternative rating method (ARM) approved by DOE; or
(b) Representation of non-tested combinations at the same energy
efficiency level as the tested combination with the same outdoor unit.
(4) This waiver shall remain in effect from the date this 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 be revoke or modify the 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.
Issued in Washington, DC, on April 30, 2010.
