SUPPLEMENTARY INFORMATION: Title III of the Energy Policy and 
Conservation Act (EPCA) sets forth a variety of provisions concerning 
energy efficiency. Part B of Title III (42 U.S.C. 6291-6309) provides 
for the ``Energy Conservation Program for Consumer Products other than 
Automobiles.'' Part C of Title III (42 U.S.C. 6311-6317) 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 equipment, packaged boilers, water heaters, 
and other types of commercial equipment.
    Today's notice involves both residential products under Part B, and 
commercial equipment under Part C. Both parts specifically provide for 
definitions, test procedures, labeling provisions, energy conservation 
standards, and the authority to require information and reports from 
manufacturers. With respect to test procedures, both parts generally 
authorize the Secretary of Energy 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, 6314)
    Samsung's petition requests a waiver from both the residential and 
commercial test procedures for its DVM products, which are sold for 
both residential and commercial use.
    As noted above, the test procedures for residential products appear 
at 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 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)) This section also provides for 
the Secretary of Energy to amend the test procedure for a product if 
the industry test procedure is amended, unless the Secretary determines 
that such a modified test procedure does not meet the statutory 
criteria. (42 U.S.C. 6314(a)(4)(B)) On October 21, 2004, the Department 
published a direct final rule, effective December 20, 2004, adopting 
ARI Standard 210/240-2003 for small commercial package air conditioning 
and heating equipment with capacities <=65,000 Btu/h and ARI Standard 
340/360-2000 for small commercial package air conditioning and heating 
equipment with capacities >=65,000 Btu/h and <135,000 Btu/h. (69 FR 
61962) The capacities of Samsung's DVM products sold for commercial use 
fall in a range covered by ARI Standard 340/360-2000. Therefore, it is 
the applicable test procedure for this commercial equipment.
    The Department's regulations contain provisions allowing a person 
to seek a waiver from the test procedure requirements for covered 
consumer products. These provisions are set forth in 10 CFR 430.27. The 
Department proposed waiver provisions for covered commercial equipment 
on December 13, 1999 (64 FR 69597), as part of the commercial furnace 
test procedure rule. The waiver provisions for commercial equipment are 
substantively identical to those for covered consumer products. The 
Department published a final rule on October 21, 2004, codifying this 
process in 10 CFR 431.201, effective November 22, 2004. (69 FR 61915)
    The waiver provisions allow the Assistant Secretary for Energy 
Efficiency and Renewable Energy to waive temporarily test procedures 
for a particular basic model when a petitioner shows that the basic 
model contains one or more design characteristics that prevent testing 
according to the

[[Page 9630]]

prescribed test procedures, or when 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 Sections 430.27(a)(1), 431.201(a)(1)) Waivers generally 
remain in effect until final test procedure amendments become 
effective, thereby resolving the problem that is the subject of the 
waiver.
    The waiver process also allows the Assistant Secretary for Energy 
Efficiency and Renewable Energy (Assistant Secretary) to grant an 
Interim Waiver from test procedure requirements to manufacturers that 
have petitioned DOE for a waiver of such prescribed test procedures. 
(10 CFR 430.27(a)(2), 431.201(a)(2)) 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.
    On October 7, 2003, Samsung filed an Application for Interim Waiver 
and a Petition for Waiver from the test procedures applicable to 
residential and commercial package air conditioning and heating 
equipment. In particular, Samsung requested a waiver from the 
residential test procedures contained in 10 CFR Part 430, Subpart B, 
Appendix M, and, for commercial products, a waiver from the test 
procedures in ARI 210/240 (1989), and from the test procedures 
contained in ARI 210/240 (1994), that the Department, at the time, 
proposed to adopt. As discussed above, for Samsung's commercial 
products, the applicable test procedure is now ARI 340/360-2000. 
Samsung requests a waiver from the test procedures for the following 
basic product models:
    Commercial: Any product using these outdoor units: RVMH100FAMOU, 
RVMC100FAMOU, RVMC070FAMOU. For these products, the applicable test 
procedure is ARI 340/360-2000.
    Residential: Any product using these outdoor units: RVMH050CBMOU, 
RVMC050CBMOU. DVM indoor units: AVMKH020CAOU, AVMKC020CAOU, 
AVMKH032CAOU, AVMKC032CAOU, AVMKH040CAOU, AVMKC040CAOU, AVMCH052CAOU, 
AVMCC052CAOU, AVMCH072CAOU, AVMCC072CAOU, AVMCH105CAOU, AVMCC105CAOU, 
AVMBH020CAOU, AVMBC020CAOU, AVMBH032CAOU, AVMBC032CAOU, AVMBH040CAOU, 
AVMBC040CAOU, AVMBH052CAOU, AVMBC052CAOU, AVMBH072CAOU, AVMBC072CAOU, 
AVMHH105CAOU, AVMHC105CAOU, AVMHH128CAOU, AVMHC105CAOU, AVMDH052CAOU, 
AVMDC052CAOU, AVMDH072CAOU, AVMDC072CAOU, AVMWH020CAOU, AVMWCH020CAOU, 
AVMWH032CAOU, AVMWC032CAOU, AVMWH040CAOU, AVMWC040CAOU, AVMWH052CAOU, 
AVMWC052CAOU, AVMWH072CAOU, AVMWC072CAOU. For these products, the 
applicable test procedure is the residential test procedure contained 
in 10 CFR Part 430, Subpart B, Appendix M.
    Samsung seeks a waiver from the applicable test procedures because, 
Samsung asserts, the current test procedures evaluate its DVM (Digital 
Variable Multi) systems in a manner not representative of their true 
energy efficiency. Samsung claims that the energy usage of its DVM 
systems cannot be representatively measured using the current test 
procedures for the following reasons:
    1. Unlike the DVM system, no product currently for sale in the U.S. 
offers the ability of a direct expansion system to vary its capacity 
every 20 seconds between 10% and 100% of the building design load, and 
no existing test procedure can provide a method for rating at those 
capacity points.
    2. No existing test procedure requires calculating Integrated Part 
Load Values (IPLV) in the heating mode.
    3. No existing test procedure accounts for the benefits of the DVM 
system's zoned cooling. No existing test standard allows for the 
inherent benefits of eliminating duct loss in a ductless system.
    4. No existing test procedure provides a method for testing and 
rating a system that utilizes one outdoor unit and sixteen indoor 
units.
    5. No existing test procedure can provide a method for rating 
systems where the type and capacity of the indoor unit can be mixed in 
the same system. The DVM system can mix together six different indoor 
models with seven different capacities, resulting in over 1,000 
combinations.
    The Samsung petition requests that DOE grant a waiver from existing 
test procedures until such time as a representative test procedure is 
developed and adopted for this class of products. Samsung intends to 
work with ARI to develop appropriate test procedures.
    Samsung also requested an Interim Waiver to allow it to work with 
manufacturers of similar products and industry organizations to develop 
a test procedure that accurately reflects the operation and energy 
consumption of these types of units. 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 
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), 431.201(e)(3))
    Samsung's Application for Interim Waiver does not provide 
sufficient information to evaluate what, if any, economic hardship 
Samsung 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. For Samsung's commercial DVM 
products, it appears likely that the Petition for Waiver will be 
granted. The Samsung DVM products are quite similar to the Mitsubishi 
City Multi products, for which DOE granted a waiver. (69 FR 52660, 
August 27, 2004) The Mitsubishi waiver was granted because Mitsubishi's 
products cannot be tested according to the prescribed test procedures, 
for two reasons: (1) Test laboratories cannot test products with so 
many indoor units (up to sixteen--the practical limit is about five); 
and (2) there are 58 indoor unit models, so for each outdoor unit, 
there are well over 1,000,000 combinations, and it is impractical to 
test so many combinations.
    Samsung's commercial outdoor units are capable of operating up to 
sixteen indoor units. Samsung's system also allows for over 1,000 
combinations of indoor and outdoor units. The upper limit on the number 
of indoor units that are currently able to be tested is about six. The 
Samsung commercial systems (with 100k and 72k Btu/hr outdoor units) 
will therefore experience the same testing problems that prompted DOE 
to grant Mitsubishi a waiver.
    Samsung's residential models, with a 50k Btu/hr outdoor unit, are 
capable of operating up to seven indoor units. This would still be 
difficult to test, but it is not clear that it could not be tested. 
However, although it may be possible to test Samsung's residential DVM 
systems, it is not practical to do so. For standard split system air 
conditioners with one indoor unit, DOE's regulations allow use of an 
alternative rating method (ARM) for generating efficiency ratings of 
different combinations of indoor and outdoor units. There is no such 
ARM for systems with more than one indoor unit, so Samsung would

[[Page 9631]]

have to test every combination offered for sale. With up to seven 
indoor units of six different types, thousands of combinations are 
possible, and it would not be practical to test so many combinations. 
This is the second of the two reasons for which Mitsubishi received a 
waiver; therefore, it appears likely that Samsung's residential DVM 
products will also be granted a waiver.
    Therefore, Samsung's Application for an Interim Waiver from the DOE 
test procedure for its DVM systems is granted. Hence, it is ordered 
that:
    The Application for Interim Waiver filed by Samsung is hereby 
granted for any Samsung DVM product using these outdoor units: 
RVMH100FAMOU, RVMC100FAMOU, RVMC070FAM0U, RVMC050CBM0U, and 
RVMH050CBM0U. Samsung shall not be required to test or rate these 
products on the basis of the currently applicable test procedure, which 
is ARI 340/360-2000 for the first three of the above outdoor units, 
which are commercial, and the test procedures contained in 10 CFR Part 
430, Subpart B, Appendix M, for the latter two, which are residential.
    This Interim Waiver is based upon the presumed validity of 
statements and allegations submitted by the company. This Interim 
Waiver may be removed or modified at any time upon a determination that 
the factual basis underlying the Application is incorrect.
    The Interim Waiver shall remain in effect for a period of 180 days 
or until DOE acts on the Petition for Waiver, whichever is sooner, and 
may be extended for an additional 180-day period, if necessary.
    The Department is publishing Samsung's Petition for Waiver in its 
entirety. The Petition contains no confidential information. The 
Department solicits comments, data, and information with respect to the 
Petition. The Department is particularly interested in receiving 
comments and views of interested parties concerning any alternate test 
procedures, modifications to test procedures, or alternative rating 
methods, which the Department could use to fairly represent the energy 
efficiency of Samsung's DVM products. Any person submitting written 
comments must also send a copy of such comments to the petitioner. 10 
CFR 430.27(b)(1)(iv).

October 7th 2003

Mr. Michael Raymond
Office of Building Research and Standards
United States Department of Energy
1000 Independence Avenue, SW
Washington, DC 20585-0121

Dear Mr. Raymond

    I am writing this letter to you in regard to the process for a 
Petition for Waiver and application for interim waiver of test 
procedures.
    Samsung Air Conditioning, acting through it's exclusive 
distributors in the USA, Quietside Corporation hereby petitions the 
United States Department of Energy for a Waiver of all Test 
procedures and makes application for an interim waiver pursuant to 
the provisions of 10 CFR 431.29.
    To support this petition, please consider the following 
submission.

1. Models Covered by the Scope of This Petition

    The Samsung DVM system products consist of three capacities of 
Outdoor units, nominally 100,000 Btu/h, 72,000 Btu/h and 50,000 Btu/
h, operating on 208/230V-3Ph-60Hz (100k & 72k units) and 208/230V-
1Ph-60Hz (50k unit).
    These units are available in both Cooling only and Heat Pump 
models (72k is Cooling only) and these outdoor units can be matched 
with six different types of indoor unit--

Built in Duct
Low Silhouette Duct
High Static Pressure Duct
4 Way Ceiling Cassette
1 Way Ceiling Cassette
High Wall Mount unit

    These indoor units are available in capacities from 7,000 Btu/h 
to 44,000 Btu/h depending on the model type.

Appendix 1: Full model list and description of items covered by 
petition

2. Inherent Characteristics of the Samsung DVM System

    The Samsung DVM system is a Commercial and Residential multi 
split, multi zoned variable refrigerant flow system that will 
provide either heating or cooling to the building as dictated by the 
individual zone temperature.
    The 100k & 72k Outdoor units are capable of operating up to 16 
indoor units, and the 50,000 Btu/h Outdoor unit is capable of 
operating up to 7 indoor units
    All of the indoor units are capable of operating independently, 
with their own temperature and fan speed setting. Based on those 
controls the outdoor unit will then determine the cooling or heating 
capacity delivered into the zones. The outdoor unit uses the 
following inputs to determine the capacity required by the zone--

Set Temperature (User selectable)
Room temperature (Measured in the return air of the unit)
Refrigerant temperature at the Evaporator Inlet
Refrigerant temperature at the Evaporator Outlet
Outdoor ambient temperature

    The Samsung DVM system cannot provide simultaneous Heating and 
Cooling functions into the zones, however it will operate to satisfy 
the building demands in the following manner--

First unit calling for operation
Majority rules for the building
All other zone requirements

    The Outdoor and Indoor units communicate the control information 
listed above every 20 seconds to calculate the indoor capacity 
required for the next 20 seconds of operation, allowing the unit to 
correctly assess the load characteristics of the building and adjust 
the capacity output accordingly.
    The method for controlling the capacity is to vary the quantity 
of refrigerant flowing through the entire system at any given time.
    The compressor(s) used in the Samsung DVM system are 
manufactured by Copeland in Sidney OH, and are a ``Digital Scroll'' 
type. This revolutionary compressor allows the system capacity to be 
varied from 10% to 100% depending on the indoor load. This is 
accomplished by allowing the fixed and orbiting scrolls inside the 
compressor to separate during unloaded periods, which stops 
refrigerant flow through the compressor and operates the compressor 
motor in an unloaded fashion, which greatly reduces the power 
consumed by the compressor,
    The outdoor unit also uses variable speed condenser fan motor(s) 
which can alter condenser airflow to exactly suit the outdoor air 
temperature and building load to ensure the unit operates in the 
most efficient manner possible.
    The Indoor units all utilize an Electronic Expansion Valve (EEV) 
which operates over a 480 step range from fully closed to fully 
open. This extensive range allows precise monitoring of the 
refrigerant quantity entering the evaporator coil and hence the 
cooling or heating capacity of the unit.
    This type of product will almost always operate below the 100% 
capacity threshold (part load versus full load operation), and due 
to the enhanced capacity control range of the DVM system it can 
operate at 10% capacity if the building load has reduced to that 
point.
    This type of operation is very similar to the Water Chilling 
units as detailed in ARI standard 550/590.

3. Waiver Requirements

    Samsung/Quietside seeks a waiver of all current test standards 
until a test standard can be developed and adopted that will provide 
the HVAC market in the United States (US) with a fair and accurate 
assessment of the DVM system energy consumption and efficiency 
levels.
    The current test procedures in place may evaluate the DVM system 
in a manner that is not representative of the true energy efficiency 
of the DVM system and provide inaccurate ratings which would be used 
to compare the DVM system with other forms of Air Conditioning/Heat 
Pumps in the market.
    Due to the constant variation of the system capacity it is 
patently inaccurate to rate the unit at its full load capacity or at 
any other fixed point of capacity when the unit capacity is 
constantly varying between 10% and 100% of the capacity.

[[Page 9632]]

    Any test method utilized to rate these types of full variable 
refrigerant flow units should be indicative of the ability of these 
units to operate at 10%, 20%, 30% * * * 100% as this is the true 
operation of the unit in the field.
    During 2002 a committee was formed by ARI to discuss alternate 
test methods for this type of multi split variable refrigerant flow 
unit, however to this date no additional test methodology has been 
adopted by the committee. As the Department is aware the timeframe 
for drafting and approving such a standard may be months or even 
years. The International Standards Organization have been currently 
working on a standard of their own for several years at this point 
in time.
    Due to the lack of an approved standard at this present time, 
the energy savings provided by the DVM System would not be 
accurately represented should it be tested under the current 
standards. This inaccurate representation will have a negative 
impact upon the sales of both the Samsung DVM system and other 
Variable Refrigerant Volume systems. This will not only greatly 
affect the business revenue of Quietside and Samsung, but it will 
prevent the country from realizing energy savings, particularly in 
the area of peak load usage reduction.
    To summarize, the test waiver for the DVM system is requested 
for the following reasons:
    A. No product currently for sale in the USA offers the ability 
of a direct expansion system to vary its capacity every 20 seconds 
between 10% and 100% of the building design load, and no existing 
test standard can provide a method for providing ratings at those 
capacity points.
    B. No existing test standard allows for IPLV to be calculated in 
the Heating mode.
    C. No existing test standard provides for the benefits of 
diversity due to the inherent ability of the DVM System to provide 
zoned cooling. Also no existing test standard provides for credit 
for negating duct loss from the nonducted units available with this 
system.
    D. No existing test standard provides a method to test and rate 
a system that utilizes one outdoor unit and 16 indoor units.
    E. No existing test standard can provide a method for rating 
systems where the type and capacity of indoor unit can be used. The 
DVM system can mix 6 different indoor models in up to 7 different 
capacities. For example a 100,000 Btu/h system can use 2 x 11,000 
Btu/h units of different models, 2 x 13,000 Btu/h units of 
additional models, 2 x 24,000 Btu/h models from additional models 
and still not be at 100% capacity load. The total number of unit 
combinations available is over 1,000, not including the ability to 
over or under size the indoor capacity with regard to the outdoor 
unit capacity.

4. Similar Equipment Currently Offered for Sale in the U.S.

Sanyo
Mitsubishi Comfort Systems
Mitsubishi Electric U.S.
    The above companies currently offer similar systems for sale in 
the United States, these systems offer similar advantages and energy 
savings inherent to all Variable Refrigerant Flow units, however no 
other manufacturer utilizes the ``Digital Scroll'' technology and 
the capacity range of the DVM system.
    Mitsubishi Electric U.S. currently has a test waiver proposal in 
front of the Department that has been published for comment in the 
Federal Register.

5. Reasons for Granting a Test Waiver to the DVM System

    The Samsung DVM System is currently offered for sale in the U.S. 
marketplace, however the lack of an existing or proposed test 
standard has resulted in the unit having to be provided with Energy 
Guide labels detailing a 10 SEER, the lowest possible rating. The 
true SEER of the DVM system would be a minimum of 50% higher.
    This failure to correctly rate the energy efficiency of the unit 
also does not allow the performance of the DVM system to be 
certified by the ARI (no applicable test standard or test 
availability), which causes a misconception of the efficiency level 
of the DVM system and provides wholly inaccurate data to the U.S. 
consumer.
    These types of Variable Refrigerant Flow products are very well 
established in the Asian and European markets, based on the high 
levels of efficiency and comfort provided to the end user. U.S. 
consumers should not be excluded from these benefits due to the lack 
of an applicable test standard, and should not be beholden to 
inaccurate data that will heavily disadvantage the DVM system or any 
other Variable Refrigerant Flow system in a very competitive 
marketplace.
    Independent testing of the DVM system against conventional Air 
conditioning systems shows an average of over 30% reduction on 
energy consumption, not even including the reduction in peak load 
operating consumption.
    Samsung test data, showing EER values (Watt for Watt) shows 
almost a full EER point increase over VAV and compressor control 
units, and a similar increase over an Inverter Variable Refrigerant 
Flow system. This test data is included in Appendix 2.
    The disadvantage of the lack of an applicable test standard will 
not only impact the potential sales of the DVM system, but also 
result in economic losses not only for Samsung and Quietside but 
also for the Copeland Corporation who have spent considerable time 
and resources in developing the ``Digital Scroll'' compressors.
    Samsung/Quietside formally urges the Department to grant an 
interim waiver from existing test standards and allow Quietside to 
work in conjunction with the other manufacturers of Variable 
Refrigerant Flow products and the various organizations involved in 
our industry to formulate a test standard that accurately reflects 
the operation and energy consumption of these types of units.
    Should the Department have any comments or questions regarding 
this petition please do not hesitate to contact the undersigned.
