V. Summary and Request for Comments
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 establishes the ``Energy Conservation Program for Consumer
Products Other Than Automobiles.'' (42 U.S.C. 6291-6309) Similar to the
Program in Part B, Part C of Title III provides for an energy
efficiency program titled ``Certain Industrial Equipment,'' which
includes commercial air conditioning and heating equipment, package
boilers, water heaters, and other types of commercial equipment. (42
U.S.C. 6311-6317)
This notice involves residential products under Part B, as well as
commercial equipment under Part C. Under both parts, the statute
specifically includes definitions, test procedures, labeling
provisions, energy conservation standards, and the authority to require
information and reports from manufacturers. (42 U.S.C. 6291-6296; 6311-
6316) With respect to test procedures, both parts authorize 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. 6293(b)(3);
6314(a)(2))
Relevant to the current Petition for Waiver, the test procedure for
residential central air conditioning and heat pump products is set
forth in 10 CFR Part 430, Subpart B, Appendix M. 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 [Illuminating Engineering Society
of North America] 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 in the Federal
Register adopting test procedures for commercial package air
conditioning and heating equipment, effective January 8, 2007. 71 FR
71340. DOE adopted ARI Standard 210/240-2003 for commercial package air
conditioning and heating equipment with capacities < 65,000 British
thermal units per hour (Btu/h) and ARI Standard 340/360-2004 for
commercial package air conditioning and heating equipment with
capacities >=65,000 Btu/h and <240,000 Btu/h. Id. at 71371. Pursuant
[[Page 181]]
to this rulemaking, DOE's regulations at 10 CFR 431.95(b)(2)
incorporate by reference the relevant ARI standards, and DOE's
regulations at 10 CFR 431.96 direct 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 Sanyo's ECO-i VFR commercial and residential multi-split
products respectively fall in the ranges covered by ARI Standard 340/
360-2004 and the DOE test procedure for residential products referred
to above.)
DOE's regulations contain provisions allowing a person to seek a
waiver from the test procedure requirements for covered consumer
products, if the petitioner's basic model contains one or more design
characteristics that prevent testing according to the prescribed test
procedures, or if the test procedures may evaluate the basic product in
a manner so unrepresentative of its true energy consumption as to
provide materially inaccurate comparative data. 10 CFR 430.27(a)(1).
The waiver provisions for commercial equipment are substantively
identical to those for covered consumer products and are found at 10
CFR 431.401(a)(1). 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 430.27(b)(1)(iii); 10
CFR 431.401(b)(1)(iii). The Assistant Secretary for Energy Efficiency
and Renewable Energy (the Assistant Secretary) may grant the waiver
subject to conditions, including adherence to alternate test
procedures. 10 CFR 430.27(l); 10 CFR 431.401(f)(4). Waivers generally
remain in effect until the effective date of a final rule 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 430.27(m); 431.401(g).
The waiver process also permits parties submitting a Petition for
Waiver to file an Application for Interim Waiver from the prescribed
test procedure requirements. 10 CFR 430.27(a)(2); 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
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
430.27(g); 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 is sooner, and may be extended for an
additional 180 days, if necessary. 10 CFR 430.27(h); 10 CFR
431.401(e)(4).
II. Petition for Waiver
On February 22, 2007, Sanyo filed a Petition for Waiver from the
test procedures applicable to residential and commercial package air-
conditioning and heating equipment and an Application for Interim
Waiver. The applicable test procedure for Sanyo's residential ECO-i
multi-split products is the DOE residential test procedure found in 10
CFR Part 430, Subpart B, Appendix M. For Sanyo's commercial ECO-i
multi-split products, the applicable test procedure is ARI 340/360-
2004, because, as discussed in the previous section I above (Background
and Authority), this is the test procedure specified in Tables 1 and 2
to 10 CFR 431.96.
Sanyo seeks a waiver from the DOE test procedures for this product
class on the grounds that its ECO-i multi-split heat pump and heat
recovery systems contain design characteristics that prevent testing
according to the current DOE test procedures. Specifically, Sanyo
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 waiver granted to Mitsubishi Electric &
Electronics USA, Inc. (Mitsubishi) for a similar line of commercial
multi-splits:
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 52660, 52661 (August 27, 2004).
Further, Sanyo states that its ECO-i product offering is a multi-
split system incorporating a diverse amount and configuration of indoor
units for connection to a single outdoor unit, and that it is
impractical to test the performance of each system under the current
DOE test procedure. The number of connectable indoor units for each
outdoor unit ranges from 6 to 28. Furthermore, the indoor units are
designed to operate at many different external static pressure values,
which compounds the difficulty of testing. A testing facility could not
manage proper airflow at several different external static pressure
values for the many indoor units that would be connected to an ECO-i
outdoor unit.
Accordingly, Sanyo requests that DOE grant a test procedure waiver
for its ECO-i product designs, until a suitable test method can be
prescribed. Furthermore, Sanyo states that failure to grant the waiver
would result in economic hardship because it would prevent the company
from marketing its ECO-i products. Also, Sanyo states that it is
willing to work closely with DOE, the Air-Conditioning and
Refrigeration Institute (ARI), and other agencies to develop
appropriate test procedures, as necessary.
III. Application for Interim Waiver
On February 22, 2007, in addition to its Petition for Waiver, Sanyo
also submitted an Application for Interim Waiver to DOE. Sanyo's
Application for Interim Waiver does not provide sufficient information
to evaluate the level of economic hardship Sanyo 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 a similar
product design, 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 Fujitsu, Samsung, and Daikin for
comparable residential and commercial multi-split air conditioners and
heat pumps. 70 FR 5980 (Feb. 4, 2005); 70 FR 9629 (Feb. 28, 2005); 72
FR 53237 (Sept. 18, 2007), respectively.
Moreover, as noted above, DOE approved the Petition for Waiver from
Mitsubishi for its comparable line of commercial multi-split air
conditioners and heat pumps. 69 FR 52660 (August 27, 2004). The two
principal reasons for granting these waivers also apply to Sanyo's VRV-
II-S products: (1) Test laboratories cannot test products with so many
indoor units \1\; 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 Sanyo's Petition for Waiver will be
granted for its new ECO-i multi-split models. Therefore, it is ordered
that:
---------------------------------------------------------------------------
\1\ According to the Sanyo petition, up to 28 indoor units are
possible candidates for testing of its residential and commercial
multi-split air conditioners and heat pumps. However, DOE believes
that the practical limits for testing would be about five units.
---------------------------------------------------------------------------
The Application for Interim Waiver filed by Sanyo is hereby granted
for Sanyo's ECO-i multi-split central air conditioners and central air-
conditioning heat pumps, subject to the specifications and conditions
below.
[[Page 182]]
The Interim Waiver applies to the following models:
1. Sanyo shall not be required to test or rate its ECO-i
residential products on the basis of the currently applicable test
procedure, which is set forth in 10 CFR 430, Subpart B, Appendix M.
Sanyo shall not be required to test or rate its ECO-i commercial
products on the basis of the currently applicable test procedure, which
is set forth in ARI Standard 340/360-2004.
2. Sanyo shall be required to test and rate its ECO-i products
according to the alternate test procedure as set forth below in section
IV(3), ``Alternate test procedure.''

This Interim Waiver is conditioned upon the presumed validity of
statements, representations, and documentary materials provided by the
petitioner. DOE may revoke or modify this Interim Waiver at any time
upon a determination that the factual basis 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. The Mitsubishi petitions, including the alternate test
procedure, were published in the Federal Register on April 9, 2007. 72
FR 17528, 17532. For similar reasons, DOE believes that alternate test
procedures are necessary here.
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.
Therefore, as discussed below, DOE is including an alternate test
procedure as a condition in granting the Interim Waiver for Sanyo's
products, and plans to consider the same alternate test procedure in
the context of the subsequent Decision and Order pertaining to Sanyo's
Petition for Waiver. Utilization of this alternate test procedure will
allow Sanyo to test and make energy efficiency representations for its
ECO-i products. More broadly, DOE has also applied 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 Decision and Order for its multi-split products at 72 FR
71387 (Dec. 17, 2007), and Fujitsu's Decision and Order 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 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
products. In the present case, DOE is modifying the alternate test
procedure taken from the above-referenced waiver granted to Mitsubishi
for its R410A CITY MULTI products, and plans to consider inclusion of
the following similar waiver language in the Decision and Order for
Sanyo's ECO-i multi-split air conditioner and heat pump models:
(1) The ``Petition for Waiver'' filed by Sanyo Fisher Company
(Sanyo) is
[[Page 183]]
hereby granted as set forth in the paragraphs below.
(2) Sanyo shall not be required to test or rate its ECO-i variable
refrigerant volume multi-split air conditioner and heat pump products
listed above in section III, on the basis of the current 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) Sanyo 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 Parts 430 and 431, except
that:
(i) For products covered by 10 CFR Part 430 (consumer products),
Sanyo shall not be required to comply with: (1) The first sentence in
10 CFR 430.24(m)(2), which refers to ``that combination manufactured by
the condensing unit manufacturer likely to have the largest volume of
retail sales''; and (2) the third sentence in 10 CFR 430(m)(2),
including the provisions of 10 CFR 430(m)(2)(i) and (ii). Instead of
testing the combinations likely to have the highest volume of retail
sales, Sanyo may test a ``tested combination'' selected in accordance
with the provisions of subparagraph (B) of this paragraph.
Additionally, instead of following the provisions of 10 CFR
430(m)(2)(i) and (ii) for every other system combination using the same
outdoor unit as the tested combination, Sanyo shall make
representations concerning the ECO-i products covered in this waiver
according to the provisions of subparagraph (C) below.
(ii) For products covered by 10 CFR Part 430 (consumer products),
Sanyo shall be required to comply with 10 CFR Part 430, Subpart B,
Appendix M, as amended by the final rule published in the Federal
Register on October 22, 2007. 72 FR 59906. The test procedure changes
applicable to multi-split products are in sections: 2.1, 2.2.3, 2.4.1,
3.2.4 (including Table 6), 3.6.4 (including Table 12), 4.1.4.2, and
4.2.4.2.
(iii) For products covered by 10 CFR Part 431 (commercial
products), Sanyo 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, Sanyo shall make representations concerning the
ECO-i 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 ECO-i variable refrigerant volume multi-split air
conditioner and heat pump products, for compliance, marketing, or other
purposes, Sanyo 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 ECO-i multi-split combinations tested in accordance with
this alternate test procedure, Sanyo must disclose these test results.
(ii) For ECO-i multi-split combinations that are not tested, Sanyo
must make a disclosure 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 (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 Sanyo's Petition
for Waiver from the test procedures applicable to Sanyo's ECO-i
residential and commercial multi-split air conditioner and heat pump
products, and for the reasons articulated above, DOE is granting Sanyo
an Interim Waiver from those procedures. As part of this notice, DOE is
publishing Sanyo's Petition for Waiver in its entirety. The petition
contains no confidential information. Furthermore, today's notice
includes an alternate test procedure that Sanyo is required to follow
as a condition of its Interim Waiver and which DOE is considering
including in its subsequent Decision and Order. In this alternate test
procedure, DOE is defining a ``tested combination'' which Sanyo could
use in lieu of testing all retail combinations of its ECO-i multi-split
air conditioner and 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 approved by DOE, or to rate
waived products in the same manner as that for the specified tested
combination. DOE has applied 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 Waiver for its Digital Variable Multi (DVM) products at 72
FR 71387 (Dec. 17, 2007), and Fujitsu's Petition for Waiver for its
Airstage variable refrigerant flow products at 72 FR 71383 (Dec. 17,
2007).
DOE is interested in receiving comments on the issues addressed in
this notice. Pursuant to 10 CFR 430.27(d) and 10 CFR 431.401(d), any
person submitting written comments must also send a copy of such
comments to the petitioner, whose contact information is included in
the ADDRESSES section above.

Re: Petition for Waiver of Test Procedure and Application for Interim
Waiver for ECO-I Air Source Heat Pumps and Heat Recovery Products.
Dear Assistant Secretary Karsner, Sanyo Fisher Company (``SFC'') is
most excited with the opportunity to
[[Page 184]]
introduce to the United States HVAC market one of our most successful
products marketed throughout much of the world. We refer to this as our
ECO-i product line. ECO-i incorporates Variable Refrigerant Flow (VRF)
and Multi-Split Zoning characteristics with a highly advanced
integrated control system. We utilize variable speed compressor
technology to provide high efficiency operation and individual zone
control for each indoor unit.
As a result of this product line's unique design and operating
characteristics, it is currently not possible to conduct testing as
defined by ARI Standard 210/240 or ARI Standard 340/360. Therefore, SFC
respectfully submits this Petition for Waiver from Test Procedure and
simultaneously an Application for Interim Waiver of Test Procedure for
our ECO-i product line in accordance with the requirements set forth in
10 CFR 431.401 (1-1-06 Edition).
Section 1--Background
SFC's ECO-i product contains characteristics that prevent testing
of the system using the procedures outlined in ARI 210/240 as well as
ARI 340/360. Simply stated, testing laboratories cannot test products
with so many indoor units connected to a single outdoor unit. There are
also too many possible indoor unit combinations to test them all. As a
result of these issues, SFC seeks a waiver from test procedures until
such time as a permanent or interim method of testing and rating VRF
Multi-Split products is adopted.
The Department of Energy (DOE) has previously granted waivers and/
or interim waivers to other manufacturers of equipment that contain the
same basic design characteristics as that of SFC's ECO-i product line.
Table 1 as shown below provides such detail and verification related to
current and previous waiver requests for similar product.

Section 3--Design Characteristics Constituting the Grounds for Petition
ECO-i VRF products enable the connection of multiple indoor units
to a single outdoor unit. The outdoor unit is capable of part load
operation by varying refrigerant flow through the use of inverter
driven variable speed compressor technology. This results in the
outdoor units operating capacity closely matching the actual indoor
load. The ECO-i product line is designed to optimize overall system
performance and efficiency when operating at part load which
significantly decreases energy usage.
Each indoor unit of the ECO-i system may have an individual remote
controller that allows the occupant to adjust their temperature
independently of the set temperature of other indoor units connected to
the same outdoor unit. Some of the indoor units may be set to the
``off'' mode which increases energy savings even further when heating
or cooling is not required.
The variable speed compressor is capable of reducing its capacity
to approximately 7,000 BTU/hr. When this variable speed compressor is
coupled with another high performance single speed compressor(s) of
similar size in the same outdoor unit a truly remarkable minimum
capacity of as little as 7% of the rated system capacity could be
achieved resulting in significant energy savings when only a small
amount of heating or cooling is required.
Multi-split VRF technology that is incorporated in the ECO-i system
allows up to 130% of indoor unit capacity to the rated capacity of the
outdoor unit. VRF technology allows this mis-match of indoor to outdoor
capacity to save energy while still meeting the HVAC requirements of
the building.
ECO-i series ``CHDZ'' outdoor units go one step further by allowing
the consumer to operate both heating and cooling simultaneously. In the
simultaneous mode, heat is actually being removed from the ``cooling
zones'' and deposited in the ``heating zones'' via the system's heat
recovery ability. Although there is no approved or existing DOE, ARI or
ASHRAE method to recognize the systems performance during simultaneous
operation, it is certainly reasonable to believe that system efficiency
is increased. This increase in efficiency occurs because some indoor
units within the building are acting as condensers while other indoor
units are acting as evaporators at the same time. This means that heat
is transferred within the building rather than being wasted to the
outdoor environment.
Multi-split VRF technology will help our nation to reduce the
amount of energy needed to heat and cool our buildings. Sanyo is
pleased to introduce this technology to not only improve the control
that the end user has over their environment but also to help with our
nation's desire to reduce overall energy usage.
Section 4--Specific Requirements Sought to be Waived
Sanyo Petitions Waiver from the Test Procedures for all ECO-i
Series outdoor units along with their matching indoor units. Due to the
wide capacity ratings available for the ECO-i outdoor units, a waiver
is sought from the testing procedures outlined in ARI 210/240 and ARI
340/360 as identified below:
For Sanyo outdoor units with model numbers of CHX03652 and
CHX06052 (and all listed indoor units) we seek Waiver from Test
Procedures as outlined in ARI Standard 210/240-2006 (Performance Rating
of Unitary Air Conditioning and Air Source Heat Pump Equipment). This
rating and testing standard applies to unitary air conditioners and
unitary air source heat pumps rated with capacities below 65,000 BTU/
hr.
For Sanyo outdoor units with model numbers of CHDX09053,
CHDZ09053, CHDX14053 and CHDZ14053 we seek Waiver from Test Procedures
as outlined in ARI Standard 340/360-2004 (Performance Rating of
Commercial and Industrial Unitary Air Conditioning and Heat Pump
Equipment). This rating and testing standard applies to unitary air
conditioners and heat pumps with capacities ranging from 65,000 to
250,000 BTU/hr.
Regardless of the capacity of ECO-i products the basic performance,
application and utility of the equipment remain virtually identical in
that they all utilize VRF multi-split technology. All ECO-i products
utilize the same indoor units, the same piping and wiring
configurations and the same control systems regardless of capacity. The
above referenced testing and rating standards do not address the
details required to select or configure multi-split systems in a
testing facility.
SFC takes this opportunity to also request an Interim Waiver from
Test Procedure for all referenced products.
Section 5--Identity of Manufacturers of Similar Basic Models
To the best of our knowledge the following manufacturers either
currently market or previously marketed, similar VRF products within
the United States.
Daikin U.S. Corporation
Fujitsu General America
LG Electronics U.S.A., Inc.
Mitsubishi Electric & Electronics USA, Inc.
Samsung Electronics Company, Ltd.
Section 6--Alternate Testing Procedures
There is no alternative testing and rating procedures for VRF
multi-split products that SFC is aware of which could adequately
represent the performance or efficiency of this product. Our company is
an active member of the ARI Ductless Section Engineering Committee.
This committee is developing a proposed testing and rating standard for
VRF multi-split products (ARI Standard 1230) with a goal to eliminate
the need for existing and future waivers for such product.
Section 7--Need for Waiver from Test Procedure
In previous waiver petitions DOE noted that VRF multi-split systems
incorporate design characteristics that virtually eliminate the
possibility of broad testing of this type of technology. An example of
this is provided in Federal Register/Vol. 69, No. 166/Friday, August
27, 2004/Notices, page 52662 which contain the following statements:
``However, the two testing problems discussed above, (test
laboratories cannot test products with so many indoor units, and
there are too many possible combinations of indoor and outdoor units
to test), do prevent testing of the basic model according to the
prescribed test procedures.''
``The Department also consulted with the National Institute of
Standards & Technology (NIST), who agreed that many VFRZ systems
could not be tested in the laboratory.''
SFC's ECO-i product offering is a multi-split system incorporating
such a diverse amount and configuration of possible indoor units that
are able to be connected to a single outdoor unit that it is virtually
impossible to test the performance of this system. Compounding the
difficulty of testing is the fact that the indoor units are designed to
operate at so many different external static pressure values. A testing
facility could not manage proper airflow at several different external
state pressure values to the many indoor units that would be connected
to an ECO-i outdoor unit.
The challenges associated with current test procedures (of ARI 210/
240 and ARI 340/360) are being addressed by the ARI Ductless Section
Engineering Committee in hopes of overcoming such
[[Page 186]]
difficulties while still providing a means to compare the performance
of the various VRF manufacturers.
Section 8--Application for Interim Waiver
In accordance with 10 CFR 431.401 (a)(2) SFC takes this opportunity
to also submit an Application for Interim Waiver of test procedures for
our ECO-i models listed in Section 2 of this document and there
matching indoor units. SFC believes that it is likely that our Petition
for Waiver will be granted based upon, but not limited to, the
following:
The approvals of similar waiver requests as identified in
Table 1 of Section 1 of this document.
Failure to approve our Petition for Waiver and Application
for Interim Waiver will result in significant economic hardship due to
the following:
[cir] It is our intention to introduce our ECO-i product in the
Spring of 2007. A great deal of company emphasis has been, and will be,
placed on the introduction of this product, including show exhibitions
(such as AHR, ACCA, etc.), marketing/advertising campaign, customer
training and other expenditures of both financial and human resources.
Delaying our entry into the U.S. market with the ECO-i product will
impede our ability to compete in this growing market.
[cir] A significant portion of our projected sales revenues are
dependent upon the timely introduction of this product.
DOE's statement:
``* * * an interim waiver will be granted 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 Assistance
Secretary determines that it would be desirable for public policy
reasons to grant immediate relief pending a determination for the
Petition for Waiver'' (Case CAC-009), 70 Fed Reg 9629, at 9630 (Feb
28, 2005 Samsung Interim Waiver). See 10 CFR 431.201(e)(3)(2005).
SFC's ECO-i product line is quite similar to that of
Fujitsu's VRF system, Mitsubishi's City Multi system and Samsung's DVM
system. Realizing these similarities, DOE granted an:
[cir] Interim waiver to Fujitsu in January 2006 for their AirStage
Air Source product.
[cir] Interim waiver to Samsung Air Conditioning in 2005 for their
DVM System.
[cir] Interim waiver to Mitsubishi for their R-410a City Multi air
source product in March 2006.
[cir] Petition for Waiver to Mitsubishi for their R-22 City Multi
air source product in 2004.
The approval of this waiver and interim waiver is in the
best interest of our public/and government initiatives to reduce
national energy usage.
It is therefore reasonable for one to believe that SFC's petition
will also be granted.
Section 9--Conclusion
It is clear that without the approval of this Petition for Waiver
and Application for Interim Waiver that SFC will result in our
inability to compete in the United States VRF market, a market in which
our company has proven success in many other countries throughout the
world. We are pleased to have an opportunity to bring this leading edge
technology to the United States market, to not only improve the comfort
of Americans, but also to reduce the amount of energy consumed on
building cooling and heating.
SFC respectfully requests the Department of Energy to grant our
Application for Interim Waiver and our Petition for Waiver from Test
Procedure to enable our introduction of our advanced ECO-i products to
the U.S. market. Granting these requested waivers will permit us to
effectively compete in the marketplace.
Due to our near term introduction of our ECO-i product offering we
would greatly appreciate a timely response to this Petition for Waiver
from Test Procedure and Application for Interim Waiver.
Should you or any parties have questions related to this Petition
for Waiver from Test Procedure and Application for Interim Waiver,
please contact Gary Nettinger at 678-384-3115 or Davis Watkins at 678-
384-3112.
Sincerely,
Davis Watkins, Vice President; Applied Products Group, Sanyo Fisher
Company, 1690 Roberts Blvd., NW., Suite 110, Kennesaw, GA 30144.
