I. Background and Authority
Title III of the Energy Policy and Conservation Act (EPCA) sets
forth a variety of provisions concerning energy efficiency. Part B of
Title III provides for the ``Energy Conservation Program for Consumer
Products Other Than Automobiles.'' (42 U.S.C. 6291-6309) Part C of
Title III provides for an energy efficiency program entitled ``Certain
Industrial Equipment,'' which is similar to the program in Part B, and
which includes commercial air conditioning and heating equipment,
packaged boilers, water heaters, and other types of commercial
equipment. (42 U.S.C. 6311-6317)
This notice involves commercial equipment under Part C. 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, it generally authorizes the Secretary of Energy (the
Secretary) to prescribe test procedures that are reasonably designed to
produce 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 [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 a covered commercial product if the 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 ARI
Standard 340/360-2004, ``Performance Rating of Commercial and
Industrial Unitary Air-Conditioning and Heat Pump Equipment,'' for
small and large commercial package air-cooled heat pumps with
capacities >=65,000 Btu/h and <760,000 British thermal units per hour
(Btu/h). Id. at 71370. Pursuant to this rulemaking, DOE's regulations
at 10 CFR 431.95(b)(2) incorporate by reference the relevant ARI
Standard, and Table 1 to 10 CFR 431.96 directs manufacturers of
commercial package air-cooled air conditioning and heating equipment to
use the appropriate procedure when measuring energy efficiency of those
products. (The cooling capacities of Daikin's commercial VRV-III multi-
split heat pump products range from 72,000 Btu/hr to 240,000 Btu/hr,
thereby resulting in these products falling within the range covered by
ARI Standard 340/360-2004.)
In addition, DOE's regulations contain provisions allowing a person
to seek a waiver from the test procedure requirements for covered
commercial equipment, for which the petitioner's 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 of its
true energy consumption 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. Petitioners must include in
their petition any alternate test procedures known 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). 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 person who has submitted 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 a
period of 180 days or until DOE issues its determination on the
Petition for Waiver, whichever occurs first, and it may be extended by
DOE for an additional 180 days, if necessary. 10 CFR 431.401(e)(4).
II. Petition for Waiver
On August 31, 2007, Daikin filed a Petition for Waiver from the
test procedures at 10 CFR 431.96 which are applicable to commercial
package air-cooled heat pumps and an Application for Interim Waiver. As
noted above, the applicable test procedure for Daikin's commercial VRV-
III multi-split heat pumps is ARI Standard 340/360-2004, which
manufacturers are directed to use pursuant to Table 1 of 10 CFR 431.96.
The capacities of the Daikin VRV-III multi-split heat pumps range from
72,000 Btu/hr to 240,000 Btu/hr. Accordingly, the applicable test
procedure for all these sizes is ARI Standard 340/360-2004.\1\
---------------------------------------------------------------------------
\1\ Daikin's Petition mistakenly requested a waiver from ARI
210/240-2006. The capacities of the products for which the waiver is
requested are not in the range covered by ARI 210/240. ARI 340/360-
2004 is the test procedure relevant to the Daikin Petition.
---------------------------------------------------------------------------
Daikin seeks a waiver from the applicable test procedures under 10
CFR 431.96 on the grounds that its VRV-III multi-split heat pumps 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 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.
There are too many possible combinations of indoor and
outdoor units to test.
69 FR 52661 (August 27, 2004); 72 FR 17528 (April 9, 2007); 72 FR
71383 (December 17, 2007); 72 FR 71387 (December 17, 2007).
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
[[Page 1209]]
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. This is
true, but not relevant. DOE is required by EPCA to use the full-load
descriptor 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 method can be prescribed. DOE believes that there is no
substantive difference between the Mitsubishi and Daikin equipment
which would preclude it from granting the same waiver to both.
Furthermore, Daikin states that failure to grant the waiver would
result in economic hardship because it would prevent the company from
marketing its VRV-III products. Also, Daikin states that it is willing
to work closely with DOE, ARI, and other agencies to develop
appropriate test procedures, as necessary.
III. Application for Interim Waiver
On August 31, 2007, in addition to its Petition for Waiver, Daikin
submitted to DOE an Application for Interim Waiver. Daikin's
Application for Interim Waiver does not provide sufficient information
to evaluate the level of economic hardship Daikin will likely
experience if its Application for Interim Waiver is denied. However, in
those instances where the likely success of the Petition for Waiver has
been demonstrated, based upon DOE having granted a waiver for similar
product designs, it is in the public interest to have similar products
tested and rated for energy consumption on a comparable basis. DOE has
previously granted Interim Waivers to Mitsubishi, Fujitsu, and Samsung
for comparable commercial multi-split air conditioners and heat pumps.
72 FR 17533 (April 9, 2007), 70 FR 5980 (Feb. 4, 2005), 70 FR 9629
(Feb. 28, 2005), respectively.
Moreover, as noted above, DOE approved the Petition for Waiver from
Mitsubishi, Fujitsu, and Samsung for their comparable lines of multi-
split air conditioners and heat pumps. 72 FR 17528 (April 9, 2007); 72
FR 71383 (Dec. 17, 2007); 72 FR 71387 (Dec. 17, 2007). The two
principal reasons for granting the waivers also apply to Daikin's VRV-
III products: (1) Test laboratories cannot test products with so many
indoor units\2\; and (2) it is impractical to test so many combinations
of indoor units with each outdoor unit. Thus, DOE has determined that
it is likely that Daikin's Petition for Waiver will be granted for its
new VRV-III multi-split models. Therefore, it is ordered that:
---------------------------------------------------------------------------
\2\ According to the Daikin petition, up to 64 indoor units are
possible candidates for testing of its commercial package multi-
split heat pump and heat recovery systems. However, DOE believes
that the practical limits for testing would be about five units.
---------------------------------------------------------------------------
The Application for Interim Waiver filed by Daikin is hereby
granted for Daikin's VRV-III air-cooled multi-split central air
conditioning heat pumps, subject to the specifications and conditions
below. The Interim Waiver applies to the following models:

2. Daikin shall be required to test and rate its VRV-III commercial
air-cooled multi-split products according to the alternate test
procedure as set forth in section IV(3), ``Alternate test procedure.''

This Interim Waiver is conditioned upon the presumed validity of
statements, representations, and documents provided by the petitioner.
DOE may revoke or modify this Interim Waiver at any time upon a
determination that the factual basis
[[Page 1210]]
underlying the Petition for Waiver is incorrect, or upon a
determination that the results from the alternate test procedure are
unrepresentative of the basic models' true energy consumption
characteristics.
IV. Alternate Test Procedure
In response to two recent Petitions for Waiver from Mitsubishi, DOE
specified an alternate test procedure to provide a basis from which
Mitsubishi 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 Mitsubishi petitions
were published in the Federal Register on April 9, 2007. 72 FR 17528;
72 FR 17533.
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
Mitsubishi'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. The ARI committee has considered a draft ISO
methodology, ISO CD 15042, for multi-split systems. However, it
contains no guidance that would affect this waiver.
Therefore, as discussed below, DOE is including a similar alternate
test procedure as a condition in granting the Interim Waiver for
Daikin's products, and plans to consider the same alternate test
procedure in the context of the subsequent Decision and Order
pertaining to Daikin's Petition for Waiver. Utilization of this
alternate test procedure will allow Daikin to test and make energy
efficiency representations for its VRV-III products. More broadly, DOE
is also considering applying a similar alternate test procedure to
other existing waivers for similar residential and commercial central
air conditioners and heat pumps. Such cases include Samsung's Petition
for Waiver for its multi-split products at 72 FR 71387 (Dec. 17, 2007),
and Fujitsu's Petition for Waiver for its multi-split products at 72 FR
71383 (Dec. 17, 2007). As noted above, the alternate test procedure has
been applied to Mitsubishi's Petition for Waiver for its R410A CITY
MULTI and R22 and R410A multi-split products. 72 FR 17528 (April 9,
2007). DOE believes that an alternate test procedure is needed so that
manufacturers of such products can make valid and consistent
representations of energy efficiency for their air-conditioning and
heat pump products.
In the present case, DOE is modifying the alternate test procedure
taken from the above-referenced waiver granted to Mitsubishi for its
R410A and R22 CITY MULTI products, and plans to consider inclusion of
the following similar waiver language in the Decision and Order for
Daikin's VRV-III commercial multi-split air-cooled heat pump models:
(1) The ``Petition for Waiver'' filed by Daikin AC (Americas), Inc.
is hereby granted as set forth in the paragraphs below.
(2) Daikin shall not be required to test or rate its VRV-III
variable refrigerant volume multi-split heat pump products listed above
in section III, on the basis of the currently applicable test
procedures, 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 section
III above according to the test procedures for central air conditioners
and heat pumps prescribed by DOE at 10 CFR 431.96, 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 means a multi-split system with multiple
indoor coils having the following features:
(1) The basic model of a system used as a tested combination shall
consist of one outdoor unit, with one or more compressors, that is
matched with between 2 and 5 indoor units; 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 capacity that is between 95% and 105%
of the nominal capacity of the outdoor unit;
(iii) Not, individually, have a capacity that is greater than 50%
of the nominal capacity of the outdoor unit;
(iv) Operate at fan speeds that are consistent with the
manufacturer's specifications; and
(v) All 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.
(C) Representations. In making representations about the energy
efficiency of its VRV-III variable speed and variable refrigerant
volume air-cooled multi-split heat pump and heat recovery system
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 combinations tested in accordance with this
alternate test procedure, Daikin must disclose these test results.
(ii) For VRV-III combinations that are not tested, Daikin must make
a disclosure based on the testing results for the tested combination
and which is 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 (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.
V. Summary and Request for Comments
Through today's notice, DOE announces receipt of the Daikin
Petition for Waiver from the test procedures applicable to Daikin's
VRV-III commercial multi-split heat pump products, and for the reasons
articulated above, DOE is granting Daikin an Interim Waiver from those
procedures. As part of this notice, DOE is publishing Daikin's Petition
for Waiver in its entirety. The Petition contains no confidential
information. Furthermore, today's notice includes an alternate test
procedure that Daikin is required to follow as a condition of its
Interim Waiver and that DOE is considering including in its subsequent
Decision and Order. In this alternate test procedure, DOE is defining a
``tested combination'' which Daikin could use in lieu of testing all
retail combinations of its VRV-III multi-split heat pump products.
Furthermore, should a subsequent manufacturer be unable to test all
retail combinations, DOE is considering allowing such manufacturers to
rate waived products according to an ARM
[[Page 1211]]
approved by DOE, or to rate waived products the same as the specified
tested combination with the same outdoor unit. DOE is also considering
applying a similar alternate test procedure to other comparable
Petitions for Waiver for residential and commercial central air
conditioners and heat pumps. Such cases include Samsung's Petition for

Re: Petition for Waiver of Test Procedure
Dear Assistant Secretary Karsner: Daikin AC (Americas) Inc.
(DACA) respectfully petitions the Department of Energy (DOE)
pursuant to 10 CFR. Sec. Sec. 430.27(a)(1) and 431.401(a)(1) for
waivers of the test procedures applicable to residential and
commercial package air conditioners and heat pumps, as established
in ARI Standard 210/240-2006 and ARI Standard 340/360-2004,\1\ for
DACA's variable speed compressor driven air-cooled multi-split
systems for combinations exceeding two indoor units to a single
outdoor unit. The specific systems for which DACA requests these
waivers are in DACA's VRV-III product classes. The specific models
subject to the waiver requests are listed below. The basis for
DACA's requests is that the basic model contains design criteria
that prevent testing of the basic models according to the prescribed
test procedures. We are simultaneously requesting an interim waiver
for the same systems pursuant to 10 CFR Sec. Sec. 430.27(a)(2) and
431.401(a)(2).

Design Characteristics Constituting the Grounds for DACA's Petition
DACA's VRV-III product offerings consist of multiple indoor
units being connected to one or more air-cooled outdoor units. The
indoor units for these products are available in a very large number
of potential configurations, including but not limited to the
following: 4-Way Cassette, Ceiling Concealed, Wall Mounted, Ceiling
Suspended, and Floor Standing. Each of these units has nine
different indoor static pressure ratings as standard, with addition
pressure ratings available. There are over one million combinations
possible with the DACA VRV-III product offerings. It is completely
impractical for testing laboratories to test a product such as the
VRV-III with multiple indoor units because of the astronomical
number of potential system configurations.
DACA's VRV-III products share many of the design characteristics
and features of similar equipment for which DOE has already approved
either interim waivers or waivers, including DACA's VRV and VRV-S
product lines, and Mitsubishi Electric and Electronics USA, Inc.'s
(MEUS) CITY MULTI product class.\3\ The same testing constraints and
limitations apply to all of these products.
---------------------------------------------------------------------------
\3\ DOE granted DACA an interim waiver for its VRV and VRV-S
product lines in a letter dated August 14, 2006, and DOE renewed
this interim waiver on July 2, 2007 (72 FR 35,986). DOE granted MEUS
a waiver for its CITY MULTI VRFZ class of products. 69 FR 52,660
(August 27, 2004).
---------------------------------------------------------------------------
The DOE relied on similar rationales to grant MEUS' petition for
waiver and DACA's interim waiver. DOE stated the following in its
August 14, 2006 letter to DACA granting an interim waiver:
A waiver for a similar type of variable refrigerant flow zoned
central air conditioner [i.e., similar to the DACA VRV, VRV-S and
VRV-III products] was requested by MEUS. DOE decided to grant the
waiver, based on the difficulty of testing the products. There are
two major testing problems: (1) test laboratories cannot test
products with so many indoor units (up to sixteen); and (2) there
are too many possible combinations of indoor and outdoor units--only
a small fraction of the combinations could be tested.
DOE also noted in its August 14, 2006 interim waiver approval,
and in its July 2, 2007 renewal for DACA's VRV and VRV-S products
that ``[w]aivers for similar products have already been granted to *
* * Samsung, and Fujitsu General * * *.''
After reviewing its previously granted waivers for similar
products under the same rationale in its August 14, 2006 letter, DOE
concluded that DACA's VRV and VRV-S systems ``will likely suffer the
same testing
[[Page 1212]]
problems that prompted DOE to grant MEUS a waiver.'' DOE continued
by saying that ``[w]ith up to eleven indoor units of nine different
types, thousands of combinations are possible, and it would not be
practicable to test so many combinations [of DACA's VRV and VRV-S
product class].'' Based on these conclusions, the DOE proceeded to
grant DACA's interim waiver request, Id., and DOE then renewed this
interim waiver on the same basis. 72 FR 35,986 (July 2, 2007).
The DACA VRV-III system operates in the same configurations as
the VRV and VRV-S models for which DOE previously granted an interim
waiver. The reasons and rationale that DOE has already articulated
to support the previous DACA, MEUS, Sanyo, and Fujitsu waivers for
multi-split, multi-zoned air conditioners also apply to the DACA
VRV-III products. Therefore, DOE should conclude that the design
characteristics of DACA's VRV-III product classes prevent testing of
these basic models according to the prescribed test procedures.
Specific Testing Requirements Sought To Be Waived
The test procedures from which DACA is requesting a waiver are
ARI Standards 210/240-2006 and 340/360-2004. ARI Standard 210/240-
2006, which is applicable to small commercial packaged air
conditioning and heating equipment with a capacity of < 65,000 Btu/
hr, is referenced in Table 1 to 10 CFR Sec. 431.96, and is made
applicable to DACA's small commercial VRV-III products in 10 CFR
Sec. 431.96(a). ARI Standard 340/360-2004, which is applicable to
large commercial and industrial unitary air conditioning and heat
pump equipment with a capacity of >=65,000 Btu/hr to <240,000 Btu/
hr, is referenced in Table 2 to 10 CFR Sec. 431.96, and is made
applicable to DACA's large commercial VRV-III products in 10 CFR
Sec. 431.96(a).
Detailed Discussion of Need for Requested Waiver
Although the capacity of DACA's VRV-III small and large
commercial air conditioning product class are within the scope of
ARI Standard 210/240-2006 and ARI 340/360-2004, the design
characteristics of these product classes prevent testing of the
basic model according to the prescribed test procedures. The testing
procedures outlined in these two ARI standards do not provide for:
The testing of multi-split products when all connected
indoor units physically cannot be located in a single room.
The operation of indoor units at several different
static pressure ratings during a single test.
The precise number of part load tests that ARI Standard
340/360-2004 requires for fully or infinitely variable speed
products.
DACA especially requires the requested waiver because ARI
Standard 210/240-2006 and ARI Standard 340/360-2004 provide no
direction or guidance about how to test systems with millions of
combinations of indoor units configurable to a single outdoor unit.
A further reason that DACA needs the requested waiver is that
ARI Standard 210/240-2006 and ARI Standard 340/360-2004 do not
provide a test method to measure part load performance of a system
operating in simultaneous cooling and heating modes (i.e.,
performing both heating and cooling functions at the same time).
Another problem that prevents testing of the VRV-III product
classes under these ARI standards, and another major reason why DACA
requires the requested waiver, is the wide variety of indoor unit
static pressure ratings available with these and other multi-split
products. Testing facilities cannot effectively control multiple
indoor static pressures as would be required to test many of the
indoor unit combinations available. To accomplish such testing, a
testing lab would be required to use a large number of test rooms
simultaneously, and each test room would have to be networked into
the data recording instrumentation. Also, extensive piping
configurations would need to be routed throughout the various test
rooms. This process would be extraordinarily expensive, and the
logistical challenges presented by the testing might be
insurmountable.
Manufacturers of Other Basic Models Incorporating Similar Design
Characteristics
DACA is aware of the following manufacturers that produce basic
models incorporating similar design characteristics to the VRV-III
in the United States market:
Fujitsu General
Sanyo Fisher (USA) Corp.
Mitsubishi Electric & Electronics USA, Inc.
Alternative Test Procedures
There are no alternative test procedures available within the
United States to provide a means to test and to rate the performance
of such variable speed, multi-split, multi-zone product types. A
draft ISO standard (ISO CD 15042 Multi-Split Systems) is nearing
completion and is expected to soon be distributed as a Draft
International Ballot for comments. The Engineering Committee of
ARI's Ductless Section is currently working on a new draft standard
to provide testing and rating of such systems, but ARI has not
adopted a new standard and test method for this category of
equipment as of this date.
Application for Interim Waiver
DACA also hereby applies pursuant to 10 CFR Sec. 431.401(a)(2)
for an interim waiver of the applicable test procedure requirements
for its VRV-III product class models listed above. The basis for
DACA's Application for Interim Waiver follows.
DACA is likely to succeed in its Petition for Waiver because
there is no reasonable argument that ARI Standards 210/240-2006 and
340/360-2004 can be properly applied to DACA's VRV-III product
classes. As explained above in the DACA's Petition for Waiver, the
design characteristics of the VRV-III product classes clearly
prevent testing of the basic model according to the prescribed test
procedures. The likelihood of DOE approving DACA's Petition for
Waiver is buttressed by the DOE's history of approving previous
waiver requests from DACA and from several other manufacturers for
other products that are similar to the VRV-III product classes,
based on the same rationale put forth by DACA in this Petition for
Waiver. See preceding discussion of waivers granted by DOE to DACA,
MEUS, Fujitsu General, and Sanyo Fisher (USA) Corp.
Additionally, DACA is likely to suffer economic hardship and
competitive disadvantage if DOE does not grant its interim waiver
request. DACA is now preparing to introduce its VRV, VRV-S and VRV-
III models covered by this petition in a matter of months. If we
must wait for completion of the normal waiver consideration and
issuance process, DACA will be forced to delay the opportunity to
begin recouping through product sales its research, development and
production costs associated with the VRV-III product classes.
DOE approval of DACA's interim waiver application is also
supported by sound public policy reasons. As DOE stated in its
August 14, 2006 approval of DACA's interim waiver for the VRV and
VRV-S product classes:
[I]n those instances where the likely success of the Petition
for Waiver has been demonstrated, based upon DOE having granted a
waiver for a similar product design, it is in the public interest to
have similar products tested and rated for energy consumption on a
comparable basis.
The VRV-III product classes will provide superior comfort to the
end user, will allow for independent zoning of facilities from a
single outdoor unit, and will incorporate state of the art
technology such as variable speed compressors utilizing neodymium
magnets to increase efficiency and electronic control of compressor
speed, fan speed and even metering device opening positions. The
VRV-III product classes will introduce technologies that will
increase system efficiency and reduce national energy consumption,
and that will also offer a new level of comfort and control to end
users.
DACA requests that DOE grant our Application for Interim Waiver
so we can bring the new highly energy efficient technology
represented by the VRV-III product classes to the market as soon as
possible, thereby allowing the U.S. consumer to benefit from our
high technology and high efficiency product, and from competition
for other manufacturers who may have already received waivers.
Confidential Information
DACA makes no request to DOE for confidential treatment of any
information contained in this Petition for Waiver and Application
for Interim Waiver.
Conclusion
Daikin AC (Americas), Inc. Corporation respectfully requests DOE
to grant its Petition for Waiver of the applicable test procedure to
DACA for the VRV-III product designs, and to grant its Application
for Interim Waiver. DOE's failure to issue an interim waiver from
test standards would cause significant economic hardship and
competitive disadvantage to DACA by preventing DACA from marketing
these products even though DOE has previously granted a waiver to
other products currently being offered in the market with similar
design characteristics.
