SUPPLEMENTARY INFORMATION: 

I. Background and Authority 

Title III of the Energy Policy and 

Conservation Act (EPCA) sets forth a 

variety of provisions concerning energy 

efficiency, including Part B of Title III, 

which establishes the ‘‘Energy 

Conservation Program for Consumer 

Products Other Than Automobiles.’’ (42 

U.S.C. 6291–6309) part C of Title III 

provides for a similar energy efficiency 

program titled ‘‘Certain Industrial 

Equipment,’’ which includes 

commercial air conditioning equipment, 

package boilers, water heaters, and other 

types of commercial equipment.1 (42 

U.S.C. 6311–6317) 

Today’s 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, part C 

authorizes the Secretary of Energy (the 

Secretary) to prescribe test procedures 

that are reasonably designed to produce 

results that measure 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 airconditioning 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), if the industry test 

procedure for commercial package airconditioning and heating equipment is 

amended, EPCA directs the Secretary to 

amend the corresponding DOE test 

procedure unless the Secretary 

determines, by rule and based on clear 

and convincing evidence, 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. Table 1 

to Title 10 of the Code of Federal 

Regulations (10 CFR) 431.96 directs 

manufacturers of commercial package 

air conditioning and heating equipment 

to use the appropriate procedure when 

measuring energy efficiency of those 

products. For small commercial 

packaged air conditioning and heating 

water-source heat pumps with 

capacities less than 135,000 Btu/h, ISO 

Standard 13256–1 (1998) is the 

applicable test procedure. For 

commercial package air-source 

equipment with capacities between 

65,000 and 760,000 Btu/h, ARI Standard 

340/360–2004 is the applicable test 

procedure. 

DOE’s regulations for covered 

products permit a person to seek a 

waiver from the test procedure 

requirements for covered commercial 

equipment if at least one of the 

following conditions is met: (1) The 

petitioner’s basic model contains one or 

more design characteristics that prevent 

testing according to the prescribed test 

procedures; or (2) 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). 

Petitioners must include in their 

petition any alternate test procedures 

known to the petitioner 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). Waivers remain in effect 

pursuant to the provisions of 10 CFR 

431.401(g). 

The waiver process also permits 

parties submitting 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 180 

days or until DOE issues its 

determination on the petition for 

waiver, whichever occurs first. It may be 

extended by DOE for an additional 180 

days. 10 CFR 431.401(e)(4). 

II. Petition for Waiver 

On April 8, 2011, LG filed a petition 

for waiver from the test procedures at 10 

CFR 431.96 applicable to commercial 

package air-source and water-source 

central air conditioners and heat pumps, 

as well as an application for interim 

waiver. LG’s petition requested a waiver 

for the LG Multi V SYNC II multi-split 

heat pumps with capacities range from 

76,400 Btu/h to 310,000 Btu/h. The 

applicable test procedure for these airsource heat pumps is ARI 340/360– 

2004. LG’s petition also requested a 

waiver for the LG Multi V Water II 

water-source products with capacities 

ranging from 72,000 Btu/h to 573,400 

Btu/h. The applicable test procedure for 

these products with capacities less than 

135,000 Btu/h is ISO Standard 13256– 

1 (1998). The LG water-source products 

with capacities greater than or equal to 

135,000 Btu/h are not covered by this 

waiver because the DOE test procedure 

only covers water-source heat pumps 

with capacities less than 135,000 Btu/h. 

Manufacturers are directed to use these 

test procedures pursuant to Table 1 of 

10 CFR 431.96. 

LG seeks a waiver from the applicable 

test procedures under 10 CFR 431.96 on 

the grounds that its Multi V SYNC II 

and Multi V Water II multi-split heat 

pumps contain design characteristics 

that prevent testing according to the 

current DOE test procedures. 

Specifically, LG asserts that the two 

primary factors that prevent testing of 

its Multi V SYNC II and Multi V Water 

II multi-split variable speed products 

are the same factors stated in the 

waivers that DOE granted to Mitsubishi 

Electric & Electronics USA, Inc. 

(Mitsubishi) and other manufacturers 

for similar lines of commercial multisplit air-conditioning systems: 

• Testing laboratories cannot test 

products with so many indoor units; 

and 


srobinson on DSK4SPTVN1PROD with NOTICES
Federal Register / Vol. 76, No. 99 / Monday, May 23, 2011 / Notices 29735 

• There are too many possible 

combinations of indoor and outdoor 

units to test. 

See, e.g., 72 FR 17528 (April 9, 2007) 

(Mitsubishi); 76 FR 19069 (April 6, 

2011) (Daikin); 76 FR 19078 (April 6, 

2011) (Mitsubishi). 

The Multi V SYNC II and Multi V 

Water II systems have operational 

characteristics similar to the commercial 

multi-split products manufactured by 

Mitsubishi, Samsung, Sanyo, Fujitsu 

and Daikin. As indicated above, DOE 

has already granted waivers for these 

products. The Multi V SYNC II and 

Multi V Water II system consists of 

multiple indoor units connected to an 

air-cooled outdoor unit. These multisplits are used in zoned systems where 

an outdoor or water-source unit can be 

connected with up to 16–64 separate 

indoor units, which need not be the 

same models. According to LG, the 

various indoor and outdoor models can 

be connected in a multitude of 

configurations, with many thousands of 

possible combinations. Consequently, 

LG requested that DOE grant a waiver 

from the applicable test procedures for 

its Multi V SYNC II and Multi V Water 

II product designs until a suitable test 

method can be prescribed. 

III. Application for Interim Waiver 

On April 8, 2011, LG also submitted 

an application for an interim waiver 

from the test procedures at 10 CFR 

431.96 for its Multi V SYNC II and Multi 

V Water II equipment. DOE determined 

that LG’s application for interim waiver 

does not provide sufficient market, 

equipment price, shipments, and other 

manufacturer impact information to 

permit DOE to evaluate the economic 

hardship LG might experience absent a 

favorable determination on its 

application for an interim waiver. DOE 

understands, however, that if it did not 

issue an interim waiver, LG’s products 

would not be tested and rated for energy 

consumption in the same manner as 

equivalent products for which DOE 

previously granted waivers. 

Furthermore, DOE has determined that 

it appears likely that LG’s petition for 

waiver will be granted and that is 

desirable for public policy reasons to 

grant LG immediate relief pending a 

determination on the petition for 

waiver. DOE believes that it is likely 

LG’s petition for waiver for the new 

Multi V SYNC II and Multi V Water II 

multi-split models will be granted 

because, as noted above, DOE has 

previously granted a number of waivers 

for similar product designs. The two 

principal reasons supporting the grant 

of the previous waivers also apply to 

LG’s Multi V SYNC II and Multi V 

Water II products: (1) Test laboratories 

cannot test products with so many 

indoor units; and (2) it is impractical to 

test so many combinations of indoor 

units with each outdoor unit. In 

addition, DOE believes that similar 

products should be tested and rated for 

energy consumption on a comparable 

basis. For these same reasons, DOE also 

determined that it is desirable for public 

policy reasons to grant immediate relief 

pending a determination on the petition 

for waiver. 

Therefore, it is ordered that: 

The application for interim waiver 

filed by LG is hereby granted for LG’s 

Multi V SYNC II and Multi V Water II 

multi-split heat pumps, subject to the 

specifications and conditions below. 

1. LG shall not be required to test or 

rate its Multi V SYNC II and Multi V 

Water II commercial multi-split 

products on the basis of the existing test 

procedures under 10 CFR 431.96, which 

incorporates by reference ARI 340/360– 

2004 (SYNC II) and ISO Standard 

13256–1 (1998) (Water II). 

2. LG shall be required to test and rate 

its Multi V SYNC II and Multi V Water 

II commercial multi-split products 

according to the alternate test procedure 

as set forth in section IV(3), ‘‘Alternate 

test procedure.’’ 

The interim waiver applies to the

48,000 and 54,000 Btu/h respectively. 

This interim waiver is issued on the 

condition that the statements, 

representations, and documents 

provided by the petitioner are valid. 

DOE may revoke or modify this interim 

waiver at any time if it determines the 

factual basis underlying the petition for 

waiver is incorrect or the results from 

the alternate test procedure are 

unrepresentative of the basic models’ 

true energy consumption characteristics. 

DOE makes decisions on waivers and 

interim waivers for only those models 

specifically set out in the petition, not 

future models that may be manufactured 

by the petitioner. LG may submit a new 

or amended petition for waiver and 

request for grant of interim waiver, as 

appropriate, for additional models of 

commercial package air conditioners 

and heat pumps for which it seeks a 

waiver from the DOE test procedure. In 

addition, DOE notes that grant of an 

interim waiver or waiver does not 

release a petitioner from the 

certification requirements set forth at 10 

CFR part 429. 

IV. Alternate Test Procedure 

In responses to two 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. See 72 FR 

17528 and 72 FR 17533. For reasons 

similar to those published in these prior 

notices, DOE believes that an alternate 

test procedure is appropriate in this 

instance. 

DOE understands that existing testing 

facilities have limited ability to test 

multiple indoor units simultaneously. 

This limitation makes it impractical for 

manufacturers to test the large number 

of possible combinations of indoor and 

outdoor units for some variable 

refrigerant flow zoned systems. We 

further note that after DOE granted a 

waiver for Mitsubishi’s R22 multi-split 

products, ARI formed a committee to 

discuss testing issues and to develop a 

testing protocol for variable refrigerant 

flow systems. The committee has 

developed a test procedure which has 

been adopted by AHRI—‘‘ANSI/AHRI 

1230—2010: Performance Rating of 

Variable Refrigerant Flow (VRF) MultiSplit Air-Conditioning and Heat Pump 

Equipment’’ and incorporated into 

ASHRAE 90.1—2010. The commercial 

multisplit waivers that DOE has granted 

to Mitsubishi and several other 

manufacturers and the alternate test 

procedure set forth in those waivers are 

consistent with ANSI/AHRI 1230–2010. 

The waivers use a definition of ‘‘tested 

combination’’ that is substantially the 

same as the definition in ANSI/AHRI 

1230–2010. As a result, DOE is 

considering prescribing ANSI/AHRI 

1230–2010 in the subsequent decision 

and order as the alternate test procedure 

for this LG waiver. For the interim 

waiver, however, DOE will continue to 

require the use of the alternate test 

procedure prescribed in previous 

multisplit waivers. 

Therefore, as a condition for granting 

this interim waiver to LG, DOE is 

including an alternate test procedure 

similar to those granted to Mitsubishi 

for its R22 and R410A products. This 

alternate test procedure will allow LG to 

test and make energy efficiency 

representations for its Multi V SYNC II 

and Multi V Water II products. DOE has 

applied a similar alternate test 

procedure to other waivers for similar 

residential and commercial central air 

conditioners and heat pumps 

manufactured by Mitsubishi (72 FR 

17528, April 9, 2007); Samsung (72 FR 

71387, Dec. 17, 2007); Fujitsu (72 FR 

71383, Dec. 17, 2007); Daikin (73 FR 

39680, July 10, 2008); Daikin (74 FR 

15955, April 8, 2009); Daikin (74 FR 

16193, April 9, 2009); Daikin (74 FR 

16373, April 10, 2009); Mitsubishi (74 

FR 66311, 66315, December 15, 2009) 

and LG (74 FR 66330, December 15, 

2009). 

The alternate test procedure 

developed in conjunction with the 

Mitsubishi waiver permits LG to 

designate a ‘‘tested combination’’ for 

each model of outdoor unit. The indoor 

units designated as part of the tested 

combination must meet specific 

requirements. For example, the tested 

combination must have from two to 

eight indoor units so that it can be 

tested in available test facilities. (The 

‘‘tested combination’’ was originally 

defined to consist of one outdoor unit 

matched with between 2 and 5 indoor 

units. The maximum number of indoor 

units in a tested combination is 

increased in this instance from 5 to 8 to 

account for the fact that these largercapacity products can accommodate a 

greater number of indoor units.) The 

tested combination must be tested 

according to the applicable DOE test 

procedure, as modified by the 

provisions of the alternate test 

procedure as set forth below. The 

alternate test procedure also allows 

manufacturers of such products to make 

valid and consistent representations of 

energy efficiency for their airconditioning and heat pump products. 

DOE is including the following waiver 

language in the interim waiver for LG’s 

Multi V SYNC II and Multi V Water II 

commercial multi-split water-source 

heat pump models: 

(1) The petition for waiver filed by LG 

Corporation is hereby granted as set 

forth in the paragraphs below. 

(2) LG shall not be required to use 

existing test procedures to test or rate its 

Multi V SYNC II and Multi V Water II 

variable capacity multi-split heat pump 

products listed above, 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) LG 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 LG 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, 

LG shall make representations 

concerning the Multi V SYNC II and 

Multi V Water II products covered in 

this waiver according to the provisions 

of subparagraph (C) below. 

(B) Tested combination. The term 

tested combination means a sample 

basic model comprised of units that are 

production units, or are representative 

of production units, of the basic model 

being tested. For the purposes of this 


srobinson on DSK4SPTVN1PROD with NOTICES
Federal Register / Vol. 76, No. 99 / Monday, May 23, 2011 / Notices 29737 

waiver, the tested combination shall 

have the following features: 

(1) The basic model of a variable 

refrigerant flow system used as a tested 

combination shall consist of one 

outdoor unit, with one or more 

compressors, that is matched with 

between two and five indoor units. (For 

systems with nominal cooling capacities 

greater than 150,000 Btu/h, as many as 

eight indoor units may be used, to 

enable testing of non-ducted indoor unit 

combinations). 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 cooling 

capacity that is between 95% and 105% 

of the nominal cooling capacity of the 

outdoor unit; 

(iii) Not, individually, have a nominal 

cooling capacity that is greater than 

50% of the nominal cooling capacity of 

the outdoor unit; 

(iv) Operate at fan speeds that are 

consistent with the manufacturer’s 

specifications; and 

(v) 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 

§ 2.4.1 of 10 CFR part 430, subpart B, 

appendix M. 

(C) Representations. In making 

representations about the energy 

efficiency of its Multi V SYNC II and 

Multi V Water II variable capacity multisplit heat pump products for 

compliance, marketing, or other 

purposes, LG must fairly disclose the 

results of testing under the DOE test 

procedure in a manner consistent with 

the provisions outlined below: 

(1) For Multi V SYNC II and Multi V 

Water II combinations tested in 

accordance with this alternate test 

procedure, LG may make 

representations based on these test 

results. 

(2) For Multi V SYNC II and Multi V 

Water II combinations that are not 

tested, LG may make representations of 

non-tested combinations at the same 

energy efficiency level as the tested 

combination. The outdoor unit must be 

the one used in the tested combination. 

The representations must be based on 

the test results for the tested 

combination. The representations may 

also be determined by an Alternative 

Rating Method approved by DOE. 

V. Summary and Request for Comments 

Through today’s notice, DOE 

announces receipt of the LG petition for 

waiver from the test procedures 

applicable to the Multi V SYNC II and 

Multi V Water II commercial multi-split 

heat pump products specified in LG’s 

petition. For the reasons articulated 

above, DOE also grants LG an interim 

waiver from those procedures. As part 

of this notice, DOE is publishing LG’s 

petition for waiver in its entirety. The 

petition contains no confidential 

information. Furthermore, today’s 

notice includes an alternate test 

procedure that LG is required to follow

Re: Petition for Waiver and Application for 

Interim Waiver, LG Electronics Multi V 

Multi-Split Air-Source and Water-Source 

Heat Pump Systems 

Dear Assistant Secretary Kelly: LG 

Electronics, Inc. (LG) respectfully submits 

this Petition for Waiver and Application for 

Interim Waiver, pursuant to 10 CFR 431.401, 

for certain LG Multi V variable refrigerant 

flow (VRF) multi-split air-source heat 

recovery systems, specifically the Multi V 

SYNC II heat recovery (3; 460V 60 Hz), and 

LG Multi V VRF multi-split water-source heat 

pump systems, specifically the Multi V Water 

II and Multi V Water II heat recovery systems 

listed in Appendix A hereto. This request 

adds models to the waiver that DOE already 

granted to LG for Multi V SYNC II and Multi 

V Water II systems. 74 FR 66330 (Dec. 15, 

2009); see also id. 20688 (May 5, 2009) 

(interim waiver). 

Among other things, the applicable DOE 

test procedure does not provide a method for 

testing and rating a system that utilizes so 

many indoor units; the applicable test 

procedure does not provide a method for 

rating systems where the type and capacity 

of the indoor unit can be mixed in the same 

system; and no testing laboratories can test 

products with so many indoor units. See, 

e.g., 75 FR 41845, 41848 (July 19, 2010) 

(existing testing facilities ‘‘have a limited 

ability to test multiple indoor units 

simultaneously,’’ and ‘‘it is impractical to test 

some variable refrigerant flow zoned 

systems’’). 

Waiver relief has been granted for many 

other comparable commercial multi-splits, 

including LG, Mitsubishi, Samsung, Fujitsu, 

Sanyo, and Daikin. See 69 FR 52660 (Aug. 

27, 2004) (Mitsubishi); 70 FR 9629 (Feb. 28, 

2005) (Samsung); 71 FR 14858 (March 24, 

2006) (Mitsubishi); 72 FR 17528 (April 9, 

2007) (Mitsubishi); id. 71387 (Dec. 17, 2007) 

(Samsung); id. 71383 (Dec. 17, 2007) 

(Fujitsu); 73 FR 179 (Jan. 2, 2008) (Sanyo); id. 

1207, 1213 (Jan. 7, 2008) (Daikin); id. 39680 

(July 10, 2008) (Daikin); id. 75408 (Dec. 11, 

2008) (Mitsubishi); 74 FR 15955 (April 8, 

2009) (Daikin); id. 16373 (April 10, 2009) 

(Daikin); id. 20688 (May 5, 2009) (LG); id. 

66330 (Dec. 15, 2009) (LG); id. 66324 (Dec. 

15, 2009) (Daikin); id. 66311, 66315 (Dec. 15, 

2009) (Mitsubishi); 75 FR 4795 (Jan. 29, 2010) 

(Daikin); id. 13114 (March 18, 2010) (Sanyo); 

id. 22581 (April 29, 2010) (Daikin); id. 25224 

(May 7, 2010) (Daikin); id. 41845 (July 19, 

2010) (Sanyo); 76 FR 19069 (April 6, 2011) 

(Daikin); id. 19078 (April 6, 2011) 

(Mitsubishi). As stated above, LG’s current 


srobinson on DSK4SPTVN1PROD with NOTICES
29738 Federal Register / Vol. 76, No. 99 / Monday, May 23, 2011 / Notices 

1 DOE has taken the position that water-source 

products with capacities greater than or equal to 

135,000 Btu/h do not require a waiver because the 

DOE test procedure only covers water-source heat 

pumps with capacities less than 135,000 Btu/h. See, 

e.g., 75 FR 41845, 41846 (July 19, 2010) (Sanyo); id. 

22581 (April 29, 2010) (Daikin). While LG believes 

that it can rely on DOE’s position in this regard, it 

is nonetheless including products with capacities 

greater than or equal to135,000 Btu/h in this waiver 

request as a precautionary measure. 

request simply adds additional models to the 

waiver relief already granted to LG. 

LG is a manufacturer of digital appliances, 

as well as mobile communications, digital 

displays, and digital media products. Its 

appliances include air-conditioners, washing 

machines, clothes dryers, refrigerators, 

refrigerator-freezers, air cleaners, ovens, 

microwave ovens, dishwashers, and vacuum 

cleaners and are sold worldwide, including 

in the United States. LG’s U.S. operations are 

LG Electronics USA, Inc., with headquarters 

at 1000 Sylvan Avenue, Englewood Cliffs, NJ 

07632 (tel. 201–816–2000). Its worldwide 

headquarters are located at LG Twin Towers 

20, Yoido-dong, Youngdungpo-gu Seoul, 

Korea 150–721 (tel. 011–82–2–3777–1114) 

URL: http.www.LGE.com. LG’s principal 

brands include LG® and OEM brands, 

including GE® and Kenmore®. LG’s 

appliances are produced in Korea and 

Mexico. 

LG’s Multi V VRF systems are beneficial 

products, each consisting of a single outdoor 

or water source unit, using a scroll type 

inverter compressor with variable capacity, 

that can connect to multiple indoor units and 

that uses VRF and control systems. (In 

certain high capacity applications [152,900 

Btu/h and above], a consumer can choose 

between a system using a single outdoor or 

water-source unit and a system using two or 

three outdoor or water-source units.) These 

multi-splits are intended to be used in zoned 

systems where an outdoor or water-source 

unit can be connected with up to between 16 

and 64 separate indoor units, which need not 

be the same models. The operating 

characteristics allow each indoor unit to have 

a different set temperature and a different 

mode of operation (i.e., on/off/fan). All of the 

indoor units are capable of operating 

independently, with their own temperature 

and fan speed setting. Based on those 

controls, the outdoor or water-source unit 

will then determine the cooling or heating 

capacity delivered into the zones. The system 

therefore offers great flexibility and 

convenience to the consumer, permitting 

precise space conditioning control 

throughout the building, and thus saving 

energy. The cooling capacities of the systems 

are between 72,000 and 573,400 Btu/h.1

The variable speed, constant speed or dual 

compressors and the associated system 

controls can direct refrigerant flow 

throughout the system to precisely meet the 

various heating or cooling loads required in 

the conditioned areas. The compressor is 

capable of reducing its operating capacity to 

as little as 10 percent of its rated capacity. 

The outdoor fan motor also has a variable 

speed drive to properly match the outdoor 

coil to indoor loads. Zone diversity enables 

the system to have a total connected indoor 

unit capacity of up to 130 percent of the 

capacity of the outdoor or water-source unit. 

As discussed above, up to between 16 and 

64 indoor units can be matched with each 

related outdoor or water-source unit. Thus, 

for each outdoor or water-source unit there 

is a multitude of possible combinations of 

indoor units that can be matched in a system 

configuration. And since there are so many 

outdoor or water-source units and indoor 

units, there is an enormous total of possible 

combinations. 

A waiver and interim waiver for the 

specified LG Multi V VRF systems are 

warranted because test procedures under the 

Energy Policy and Conservation Act (EPCA), 

42 U.S.C. 6291 et seq., namely 10 CFR 

431.96, evaluate the basic models in a 

manner so unrepresentative of their true 

energy consumption characteristics as to 

provide materially inaccurate comparative 

data, and/or the basic models contain one or 

more design characteristics that prevent 

testing of the basic model according to the 

prescribed test procedures. In such 

circumstances DOE ‘‘will grant’’ waiver relief. 

10 CFR 431.401(e)(3), (f)(4). In that regard: 

—The test procedure provides for testing of 

a pair of indoor and outdoor assemblies 

making up a typical split system, but does 

not specify how LG Multi V VRF systems, 

with so many combinations of indoor units 

for each outdoor or water-source unit, 

could be evaluated. The situation is further 

complicated by the fact that there are so 

many outdoor or water-source units. It is 

not practical to test each possible 

combination, and the test procedure 

provides no alternative rating method for 

generating efficiency ratings for systems 

with more than one indoor unit. Thus, the 

test procedure does not contemplate, and 

cannot practically be applied to, LG Multi 

V VRF systems. DOE has already 

recognized this by granting waiver relief to 

LG, and to other manufacturers for 

comparable systems. 

—Testing laboratories cannot test products 

with so many indoor units. In that regard, 

the testing of multi-splits when all indoor 

units are connected cannot be physically 

located in a single room. 

—The test procedure provides for testing 

‘‘matched assemblies,’’ which does not 

apply to LG Multi V VRF systems. Indoor 

and outdoor coils in split systems are 

typically balanced; that is, the capacity of 

the outdoor coil is equivalent to the 

capacity of the indoor coil. The test 

procedure’s application to ‘‘matched 

assemblies’’ contemplates such a balance 

between indoor and outdoor coil capacity. 

With the Multi V VRF systems, however, 

the sum of the capacity of the indoor units 

connected into the system can be as much 

as 130 percent of the capacity of the 

outdoor coil. Such unbalanced 

combinations of LG indoor and outdoor or 

water-source units are permitted by the 

zoning characteristics of the system, the 

use of electronic expansion valves to 

precisely control refrigerant flow to each 

indoor coil, and the system intelligence for 

overall system control. The test procedure 

designed for ‘‘matched assemblies’’ 

therefore does not contemplate or address 

testing for substantially unbalanced zoning 

systems such as the LG Multi V VRF 

systems. 

—The indoor units are designed to operate at 

many different external static pressure 

values, which compounds the difficulty of 

testing LG Multi V VRF systems. A test 

facility could not maintain proper airflow 

at several different external static pressure 

values for the many indoor units that 

would be connected to the outdoor unit. 

* * * * * 

For all of these reasons, the existing test 

procedures evaluate the LG Multi V VRF 

systems in a manner so unrepresentative of 

their true energy consumption characteristics 

as to provide materially inaccurate 

comparative data and/or the basic models 

contain one or more design characteristics 

that prevent testing of the basic model 

according to the prescribed test procedures. 

Therefore, DOE should grant a waiver for the 

LG Multi V VRF systems set forth in 

Appendix A. See 10 CFR 431.401(a)(1). The 

waiver should continue until a test procedure 

can be developed and adopted that will 

provide the U.S. market with a fair and 

accurate assessment of the LG Multi V VRF 

system energy consumption and efficiency 

levels. LG intends to work with DOE, 

stakeholders, and the Air-Conditioning, 

Heating and Refrigeration Institute (AHRI) to 

develop the appropriate test procedure. 

There are no alternative test procedures 

known to LG that could evaluate these 

products in a representative manner (other 

than perhaps the procedures provided by 

DOE in its waiver decisions for comparable 

products). 

That a waiver is warranted is borne out by 

the fact that DOE has granted waiver relief to 

LG, as well as to Mitsubishi, Samsung, 

Fujitsu, Sanyo, and Daikin for comparable 

commercial multi-splits. 

Manufacturers of all other basic models 

marketed in the United States and known to 

LG to incorporate similar design 

characteristics as found in the LG Multi V 

VRF systems include Mitsubishi Electric and 

Electronics USA, Samsung Air Conditioning, 

Fujitsu General Limited, SANYO North 

America Corp., and Daikin AC (Americas), 

Inc. 

LG also requests immediate relief by grant 

of an interim waiver. Grant of an interim 

waiver is fully justified: 

—The petition for waiver is likely to be 

granted, as evidenced not only by its 

merits, but also because DOE has already 

granted waiver relief to LG, Mitsubishi, 

Samsung, Fujitsu, Sanyo, and Daikin for 

their commercial VRF multi-splits. In such 

instances, it is in the public interest to 

have similar products tested and rated for 

energy consumption on a comparable 

basis. 

—Without waiver relief, LG will be at a 

competitive disadvantage in the market 

and suffer economic hardship. LG would 

be placed in an untenable situation: the 

Multi V VRF systems involved here would 

be subject to a set of regulations that DOE 

already acknowledges should not apply to 

such a product, while at the same time 

other manufacturers are allowed to operate 

relieved from such regulations.

1718.20 (1971 Transfer Binder); 49 FR 32213 (Aug. 

13, 1984); 52 FR 49141, 49147–48 (Dec. 30, 1987). 

—Significant investment has already been 

made in LG Multi V VRF systems. Lack of 

relief would not allow LG to recoup this 

investment as it relates to the models 

involved here and would deny LG 

anticipated sales revenue. This does not 

take into account significant losses in 

goodwill and brand acceptance. 

—The basic purpose of EPCA is to foster 

purchase of energy-efficient products, not 

hinder such purchases. LG Multi V VRF 

systems produce a benefit to consumers 

and are in the public interest. To encourage 

and foster the availability of these products 

is in the public interest. Standards 

programs should not be used as a means 

to block innovative, improved designs.2

DOE’s rules should accommodate and 

encourage—not act to block—such a 

product. 

—Granting the interim waiver and waiver 

would also eliminate a non-tariff trade 

barrier. 

—Grant of relief would also help enhance 

economic development and employment, 

including not only LG Electronics USA’s 

operations in New Jersey, Georgia, Texas, 

California, Illinois and Alabama, but also at 

major national retailers and regional 

dealers that carry LG products. 

Furthermore, continued employment 

creation and ongoing investments in its 

marketing, sales and servicing activities 

will be fostered by approval of the interim 

waiver. Conversely, denial of the requested 

relief would harm the company and would 

be anticompetitive. 

Conclusion 

LG respectfully requests that DOE grant a 

waiver and interim waiver from existing test 

standards for LG Multi V VRF multi-split 

systems set forth in Appendix A hereto until 

such time as a representative test procedure 

is developed and adopted for such products. 

We would be pleased to discuss this 

request with DOE and provide further 

information as needed. 

We hereby certify that all manufacturers of 

domestically marketed units of the same 

product type have been notified by letter of 

this petition and application, copies of which 

letters are attached (Appendix B hereto).
