and Order Granting a Waiver to Daikin AC (Americas), Inc. From the
Department of Energy Commercial Package Air Conditioner and Heat Pump
Test Procedures
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Decision and order.
-----------------------------------------------------------------------
SUMMARY: This notice publishes the Department of Energy's Decision and
Order in Case No. CAC-019, which grants a waiver to Daikin AC
(Americas), Inc. (Daikin) from the existing Department of Energy (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) (commercial)
multi-split heat pumps and heat recovery systems. As a condition of
this waiver, Daikin must test and rate its VRV-III multi-split products
according to the alternate test procedure set forth in this notice.
DATES: This Decision and Order is effective April 8, 2009, and will
remain in effect until the effective date of a DOE final rule
prescribing amended test procedures appropriate for the model series of
Daikin VRV-III multi-split central air conditioners and heat pumps
covered by this waiver.

SUPPLEMENTARY INFORMATION: In accordance with 10 CFR 431.401(f)(4), DOE
gives notice of the issuance of its Decision and Order as 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 \1\ for its VRV-III multi-split products, subject to a
condition requiring Daikin to test and rate its VRV-III multi-split
products pursuant to the alternate test procedure provided in this
notice. Further, today's decision requires that Daikin may not make any
representations concerning the energy efficiency of these products
unless such product has been tested in accordance with the DOE test
procedure, consistent with the provisions and restrictions in the
alternate test procedure set forth in the Decision and Order below, and
such representations fairly disclose the results of such testing.\2\
(42 U.S.C. 6314(d))
---------------------------------------------------------------------------
\1\ The applicable 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)).
\2\ Consistent with the statute, distributors, retailers, and
private labelers are held to the same standard when making
representations regarding the energy efficiency of these products.

Principal Deputy Assistant Secretary, Energy Efficiency and Renewable
Energy.
Decision and Order
In the Matter of: Daikin AC (Americas) Inc., (Daikin) (Case No.
CAC-019).
Background
Title III of the Energy Policy and Conservation Act (EPCA) sets
forth a variety of provisions concerning energy efficiency, including
Part A\3\ of Title III which establishes the ``Energy Conservation
Program for Consumer Products Other Than Automobiles.'' (42 U.S.C.
6291-6309) Similar to the program in Part A, Part A-1\4\ of Title III
provides for an 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)
---------------------------------------------------------------------------
\3\ Part B of Title III of EPCA was redesignated Part A in the
United States Code for editorial reasons.
\4\ Part C of Title III of EPCA was redesignated Part A-1 in the
United States Code for editorial reasons.
---------------------------------------------------------------------------
Today's notice involves commercial equipment under Part A-1. The
statute specifically includes definitions, test procedures, labeling
provisions, energy conservation standards, and provides the Secretary
of Energy (the Secretary) with the authority to require information and
reports from manufacturers. 42 U.S.C. 6311-6317. With respect to test
procedures, the statute generally authorizes the Secretary to prescribe
test procedures that are reasonably designed to produce test results
which 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))
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 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 must amend the test procedure for a
covered commercial product if the applicable industry test procedure is
amended, unless the Secretary determines 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 commercial package air-
cooled air conditioning and heating equipment with capacities >=65,000
Btu/h and <240,000 Btu/h. Id. at 71371. Pursuant to this final rule,
DOE's regulations at 10 CFR 431.95(b)(1)-(2) incorporate by reference
the relevant ARI standards, and 10 CFR 431.96 directs manufacturers of
commercial package air conditioning and heating equipment to use the
appropriate procedure when measuring energy efficiency of those
products. The cooling capacities of Daikin's VRV-III VRF commercial
multi-split products, which have capacities between 72,000 Btu/hr and
240,000 Btu/hr, fall in the range covered by ARI Standard 340/360-2004.
In addition, DOE's regulations contain provisions allowing a person
to seek a waiver for a particular basic model from the test procedure
requirements for covered commercial equipment if that basic model
contains one or more design characteristics which prevent testing
according to the prescribed test procedures, or if the prescribed test
procedures may evaluate the basic model in a manner so unrepresentative
[[Page 15956]]
of its true energy consumption characteristics as to provide materially
inaccurate comparative data. 10 CFR 431.401(a)(1). The waiver
provisions for commercial equipment are found at 10 CFR 431.401 and are
substantively identical to those for covered consumer products. A
waiver petition must include any alternate test procedures known 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 (Assistant
Secretary) may grant a waiver subject to conditions, including
adherence to alternate test procedures. 10 CFR 431.401(f)(4). In
general, a waiver terminates on the effective date of a final rule,
published in the Federal Register, which prescribes amended test
procedures appropriate to the model series manufactured by the
petitioner, thereby eliminating any need for the continuation of the
waiver. 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 will terminate 180 days after issuance
or upon the issuance of DOE's determination on the Petition for Waiver,
whichever occurs first, which may be extended by DOE for an additional
180 days. 10 CFR 431.401(e)(4).
On August 31, 2007, 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,
because, as discussed above, this is the test procedure specified in
Tables 1 and 2 to 10 CFR 431.96. On January 7, 2008, DOE published
Daikin's Petition for Waiver in the Federal Register and granted the
Application for Interim Waiver. 73 FR 1207.
In a similar and relevant 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 responded favorably to DOE's proposed alternate test
procedure. Id. at17529. Also, there was general agreement 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 alternate test procedure adopted by DOE. Id
DOE received no comments on the Daikin petition.
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 multi-split heat pump and heat
recovery systems contain design characteristics that prevent testing
according to the current DOE test procedures. Specifically, Daikin
asserts 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 MEUS, Fujitsu General
Ltd. (Fujitsu), and Samsung Air Conditioning (Samsung) for similar
lines of commercial multi-split air-conditioning systems:
Testing laboratories cannot test products with so many
indoor units.
There are too many possible combinations of indoor and
outdoor unit to test. 69 FR 52661 (August 27, 2004) (MEUS); 72 FR 17528
(April 9, 2007) (MEUS); 72 FR 71383 (December 17, 2007) (Fujitsu); 72
FR 71387 (December 17, 2007) (Samsung).
Further, Daikin states that its VRV-III indoor units have nine
different indoor static pressure ratings, and the test procedure does
not provide for operation of indoor units at several different static
pressure ratings during a single test. The indoor units are designed to
operate at many different external static pressure values, which
compounds the difficulty of testing. The number of connectable indoor
units for each outdoor unit ranges up to 64. A testing facility could
not manage proper airflow at several different external static pressure
values to the many indoor units that would be connected to a VRV-III
outdoor unit. Daikin further states that its VRV-III products'
capability to perform simultaneous heating and cooling is not captured
by the DOE test procedure. Notwithstanding this fact, DOE is required
by EPCA to use the full-load descriptor Energy Efficiency Ratio (EER)
for these products, and simultaneous heating and cooling does not occur
when operating at full load.
Accordingly, Daikin requests that DOE grant a waiver from the
applicable test procedures for its VRV-III product designs, until a
suitable test procedure can be prescribed. DOE believes that the VRV-
III Daikin 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 is therefore granting to
Daikin a VRV-III product waiver similar to the previous MEUS multi-
split waivers.
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.
Daikin did not include an alternate test procedure in its Petition
for Waiver. However, in response to two recent Petitions for Waiver
from MEUS, DOE specified an alternate test procedure to provide a basis
from which MEUS could test and make valid energy efficiency
representations for its R410A CITY MULTI products, as well as for its
R22 multi-split products. Alternate test procedures related to the MEUS
petitions were published in the Federal Register on April 9, 2007. 72
FR 17528; 72 FR 17533.
To enable Daikin to make energy efficiency representations for its
specified VRV-III multi-split products, DOE has decided to require use
of the alternate test procedure described below, as a condition of
Daikin's waiver. This alternate test procedure is substantially the
same as the one that DOE applied to the waiver for MEUS's R22 and R410A
products, which was published at 72 FR 17528.
[[Page 15957]]
In general, DOE understands that existing testing facilities have a
limited ability to test multiple indoor units at one time, and the
number of possible combinations of indoor and outdoor units for some
variable refrigerant flow zoned systems is impractical to test. We
further note that subsequent to the waiver that DOE granted for MEUS's
R22 multi-split products, ARI formed a committee to discuss the issue
and to work on developing an appropriate testing protocol for variable
refrigerant flow systems. However, to date, no additional test
methodologies have been adopted by the committee or submitted to DOE.
Therefore, as discussed below, as a condition for granting this
Waiver to Daikin, DOE is including an alternate test procedure similar
to those granted to MEUS for its R22 and R410A products. DOE is issuing
today's Decision and Order granting Daikin a test procedure waiver for
its commercial VRV-III multi-split heat pumps, but is requiring the use
of the alternate test procedure described below as a condition of
Daikin's waiver. This alternate test procedure is substantially the
same as the one that DOE applied to the MEUS waiver.
Alternate Test Procedure
The alternate test procedure developed in conjunction with the MEUS
waiver has two basic components. First, it 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 from two to
eight \5\ indoor units so that it can be tested in available test
facilities. 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.
---------------------------------------------------------------------------
\5\ The ``tested combination'' was originally defined to consist
of one outdoor unit matched with between 2 and 5 indoor units. The
maximum number of indoor units in a tested combination is here
increased from 5 to 8 to account for the fact that these larger-
capacity products can accommodate a greater number of indoor units.
---------------------------------------------------------------------------
Second, having an alternate DOE test procedure that can be applied
to its products allows Daikin to represent the energy efficiency of
that product. These representations must fairly disclose the results of
such testing. 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 under a DOE-approved alternative rating
method; or (2) if the first method is not available, then at the
efficiency level of the tested combination utilizing the same outdoor
unit. Until an alternative rating method is developed, all combinations
with a particular outdoor unit may use the rating of the combination
tested with that outdoor unit.
As in the MEUS matter, DOE believes that allowing Daikin to make
energy efficiency representations for non-tested combinations by
adopting this alternative test procedure as described above 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. The multi-zoning feature of these
products, which enables them to cool only those portions of the
building that require cooling, would be expected to use less energy
than if the unit is operated to cool the entire home or a comparatively
larger area of a commercial building in response to a single
thermostat. This feature would not be captured by the current test
procedure, which requires full-load testing. Full load testing, under
which the entire building would require cooling, disadvantages these
products because they are optimized for their highest efficiency when
operating with less than full loads. Therefore, the alternate test
procedure will provide a conservative basis for assessing the energy
efficiency for such products.
With regard to the laboratory testing of commercial products, some
of the difficulties associated with the existing 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 of the indoor units must be
subject to meeting the same minimum external static pressure. This
requirement allows the test lab to manifold the outlets from each
indoor unit into a common plenum that supplies air to a single airflow
measuring apparatus and 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. This would require that the test
laboratory be equipped with multiple airflow measuring apparatuses
(which is unlikely), or that the test laboratory connect its one
airflow measuring apparatus to one or more common indoor units until
the contribution of each indoor unit has been measured.
Furthermore, DOE stated in the notice publishing the MEUS Petition
for Waiver that if the Department decided to specify an alternate test
procedure for MEUS, it would consider applying the procedure to waivers
for similar residential and commercial central air conditioners and
heat pumps produced by other manufacturers. 71 FR 14858, 14861 (March
24, 2006). Most of the comments received by DOE in response to the
March 2006 notice favored the proposed alternate test procedure. 72 FR
17529. Commenters responding to that prior notice generally agreed that
an alternate test procedure is appropriate for an interim period while
a final test procedure for these products is being developed. Id.
Based on the discussion above, DOE believes that the testing
problems described above would prevent testing of Daikin's VRV-III
multi-split products according to the test procedure currently
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 adopt the proposed
alternate test procedure for Daikin's commercial water-source products,
with the clarifications discussed 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 the issuance of 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 AC (Americas),
Inc., (Daikin) (Case No. CAC-019) is hereby granted as set forth in the
paragraphs below.
(2) Daikin shall not be required to test or rate its VRV-III VRF
multi-split air conditioner and heat pump models listed below on the
basis of the currently applicable 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 shall be 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 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) All be subject to the same minimum external static pressure
requirement.
(C) Representations. In making representations about the energy
efficiency of its VRV-III multi-split products, for compliance,
marketing, or other purposes, Daikin must fairly disclose the results
of testing under the DOE test procedure, doing so in a manner
consistent with the provisions outlined below:
(i) For VRV-III multi-split combinations tested in accordance with
this alternate test procedure, Daikin may make representations based on
these test results.
(ii) For VRV-III multi-split combinations that are not tested,
Daikin may make representations based on the testing results for the
tested combination and which are consistent with either of the two
following methods, except that only method (a) may be used, if
available:
(a) Representation of non-tested combinations according to an
alternative rating method 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 of issuance of
this Order until the effective date of a DOE final rule prescribing
amended test procedures appropriate to the model series manufactured by
Daikin listed above.
(5) This waiver is conditioned upon the presumed validity of
statements, representations, and documentary materials provided by the
petitioner. This waiver may be revoked or modified at any time upon a
determination that the factual basis underlying the Petition for Waiver
is incorrect, or DOE determines that the results from the alternate
