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 Start Printed Page 9630prescribed 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 Start Printed Page 9631have 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).Start Signature

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. Start Printed 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.
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.
