30,000, 36,000, 42,100, 48,000 and 54,000 

Btu/h, respectively. 

(3) Alternate test procedure. 

(A) LG shall be required to test the 

equipment with cooling capacities of 

300,000 Btu/h and below listed in 

paragraph (2) above according to the test 

procedure prescribed in ANSI/AHRI 

1230–2010. 

(B) LG shall be required to test the 

equipment listed in paragraph (2) above 

with cooling capacities above 300,000 

Btu/h according to the test procedures 

for commercial central air conditioners 

and heat pumps prescribed by DOE at 

10 CFR 431.96, except that LG shall test 

each model of outdoor unit with two or 

more combinations of indoor units. The 

first system combination shall be tested 

using only non-ducted indoor units that 

meet the definition of a tested 

combination, as set forth in paragraph C. 

The second system combination shall be 

tested using only ducted indoor units 

that meet the definition of a tested 

combination, as set forth in paragraph C. 

LG shall make representations 

concerning the Multi V SYNC II and 

Multi V Water II VRF multi-split heat 

pump equipment covered in this waiver 

according to the provisions of 

subparagraph (D). 

(C) 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 

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, so as to 

be able to test 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 

section 2.4.1 of 10 CFR Part 430, subpart 

B, appendix M. 

(D) Representations. In making 

representations about the energy 

efficiency of its Multi V SYNC II and 

Multi V Water II VRF multi-split 

commercial heat pumps, 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: 

(i) For Multi V SYNC II and Multi V 

Water II VRF multi-split combinations 

tested in accordance with this alternate 

test procedure, LG may make 

representations based on those test 

results. 

(ii) For Multi V SYNC II and Multi V 

Water II VRF multi-split combinations 

that are not tested, LG may make 

representations based on the testing 

results for the tested combination and 

that are consistent with one of the 

following methods: 

(a) Rating of non-tested combinations 

according to an alternative rating 

method approved by DOE. 

(b) Rating of non-tested combinations 

having the same outdoor unit and all 

non-ducted indoor units shall be set 

equal to the rating of the tested system 

having all non-ducted indoor units. 

(c) Rating of non-tested combinations 

having the same outdoor unit and all 

ducted indoor units shall be set equal to 

the rating of the tested system having all 

ducted indoor units. To be considered a 

ducted unit, the indoor unit must be 

intended to be connected with ductwork 

and have a rated external static pressure 

capability greater than zero (0). 

(d) Rating of non-tested combinations 

having the same outdoor unit and a mix 

of non-ducted and ducted indoor units 

shall be set equal to the average of the 

ratings for the two required tested 

combinations. 

(4) This waiver shall remain in effect 

from the date this Decision and Order is 

issued, consistent with the provisions of 

10 CFR 431.401(g). 

(5) This waiver is issued on the 

condition that the statements, 

representations, and documentary 

materials provided by the petitioner are 

valid. DOE may revoke or modify the 

waiver at any time if it determines that 

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. 

(6) This waiver applies only to those 

basic models set out in LG’s petition for 

waiver. 

(7) Grant of this waiver does not 

release a petitioner from the 

certification requirements set forth at 10 

CFR part 429.

1For editorial reasons, upon codification in the 

U.S. Code, Part C was re-designated Part A–1. 

SUPPLEMENTARY INFORMATION: DOE 

issues notice of this Decision and Order 

in accordance with Title 10 of the Code 

of Federal Regulations (10 CFR) 

431.401(f)(4). In this Decision and 

Order, DOE amends the current waivers 

applicable to Mitsubishi’s S&L Class 

and WR2 and WY Series products to 

require the use of AHRI 1230 as the 

alternative test procedure. Amendment 

is appropriate in this specific 

circumstance because DOE has recently 

issued waivers to other manufacturers 

using AHRI 1230 as the alternate test 

procedure for the same types of 

equipment, and AHRI 1230 is very 

similar to the alternate test procedure 

previously prescribed to Mitsubishi, but 

will provide a more conservative 

estimate of the energy consumed by this 

equipment. The waiver requires 

Mitsubishi use AHRI 1230 to test and 

rate specified models from its CITY 

MULTI WR2 and WY Series and CITY 

MULTI S&L Class multi-split equipment 

line. 

Today’s decision requires Mitsubishi 

to make representations concerning the 

energy efficiency of this equipment 

consistent with the provisions and 

restrictions of the alternate test 

procedure in the Decision and Order 

below, and the representations must 

fairly disclose the test results. (42 U.S.C. 

6314(d)) The same standard applies to 

distributors, retailers, and private 

labelers when making representations of 

the energy efficiency of this equipment. 

Id. 

Issued in Washington, DC, on October 18, 

2011. 

Kathleen B. Hogan, 

Deputy Assistant Secretary for Energy 

Efficiency, Energy Efficiency and Renewable 

Energy. 

Decision and Order 

In the Matter of: Mitsubishi Electric & 

Electronics USA, Inc. (Mitsubishi) (Case 

No. CAC–037). 

Background 

Title III, Part C of the Energy Policy 

and Conservation Act of 1975 (EPCA), 

Pub. L. 94–163 (42 U.S.C. 6311–6317), 

established the Energy Conservation 

Program for certain industrial 

equipment, which includes commercial 

air conditioning equipment, the focus of 

this decision and order.1

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 this 

equipment. For small commercial 

packaged 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 and equipment 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 

according to the provisions of 10 CFR 

431.401(g). 

On December 15, 2009, DOE granted 

Mitsubishi waivers from the DOE 

commercial air conditioner and heat 

pump test procedures for Mitsubishi’s 

CITY MULTI WR2 and WY Series 

equipment and its CITY MULTI S&L 

Class equipment. 74 FR 66311; 74 FR 

66315. On July 11, 2011, DOE granted 

Mitsubishi a waiver for additional 

indoor units. 76 FR 40714. On August 

11, 2011, Mitsubishi requested that DOE 

amend its orders granting test procedure 

waivers for these products to allow 

Mitsubishi to test and rate its WR2 and 

WY Series products, and those S&L 

Class systems that have capacities less 

than or equal to 300,000 Btu/h, 

according to the American National 

Standards Institute (ANSI)/Airconditioning, Heating and Refrigeration 

Institute (AHRI) Standard 1230–2010: 

Performance Rating of Variable 

Refrigerant Flow (VRF) Multi-Split AirConditioning and Heat Pump 

Equipment (AHRI 1230). Mitsubishi also 

requested that DOE amend the 

definition of ‘‘tested combination’’ in 

the current alternate test procedure to 

allow for the use of up to 12 indoor 

units in the configuration of a basic 

model. The alternate test procedure 

Mitsubishi is currently permitted to use 

specifies a maximum of eight indoor 

units for testing. 

Assertions and Determinations 

Mitsubishi’s Petition for Waiver 

Amendment 

Mitsubishi’s S&L Class and WR2 and 

WY Series products are part of 

Mitsubishi’s CITY MULTI Variable 

Refrigerant Flow (VRF) line of multisplit central air conditioners and heat 

pumps. As explained in Mitsubishi’s 

waivers for the WR2 and WY Series and 

the S&L Class products, these systems 

cannot be tested according to the 

prescribed test procedures for 

commercial products. Specifically, they 

contain one or more design 

characteristic that prevents testing 

according to the test procedures.

65712 Federal Register / Vol. 76, No. 205 / Monday, October 24, 2011 / Notices 

According to DOE’s grant of the 

December 2009 and July 2011 waivers, 

Mitsubishi is not required to test or rate 

the products listed in the waivers based 

on the current DOE test procedure. 

Instead, Mitsubishi is required to test 

and rate these products according to the 

alternate test procedure set forth in the 

waivers. 

The alternate test procedure 

prescribed in the December 2009 and 

July 2011 waivers was first prescribed in 

2007, in response to two other petitions 

for waiver from Mitsubishi. DOE 

specified alternate test procedures for 

representing the energy efficiency of 

Mitsubishi’s R410A and R22 CITY 

MULTI multi-split products. The 

alternate test procedure was published 

on April 9, 2007. 72 FR 17528, 72 FR 

17533. Since then, DOE has prescribed 

the same alternate test procedure for 

other manufacturers of multi-split 

products. 

After DOE granted a waiver to 

Mitsubishi’s CITY MULTI products, the 

Air-Conditioning and Refrigeration 

Institute (ARI) (now AHRI) formed a 

committee to develop a general testing 

protocol for VRF systems. The 

committee developed AHRI 1230, which 

has been incorporated into ASHRAE 

90.1–2010. AHRI 1230 establishes a test 

procedure for VRF multi-split air 

conditioners and heat pumps. The test 

procedure covers matched VRF systems 

with cooling and heating capacities for 

outdoor units between 12,000 Btu/h and 

300,000 Btu/h. DOE is assessing AHRI 

1230 with respect to the requirements 

EPCA specifies for test procedures, and 

will make a preliminary determination 

regarding AHRI 1230 in a future 

rulemaking. 

AHRI 1230 is very similar to the 

alternate test procedure in the 

commercial multi-split waivers that 

DOE previously granted to Mitsubishi 

and other manufacturers, but contains 

minor differences in the definition of 

tested combination, the testing of 

ducted versus non-ducted indoor units, 

and the line lengths. These differences 

are discussed below. 

First, the definition of ‘‘tested 

combination’’ in AHRI 1230 and the 

alternate test procedure prescribed by 

DOE in the earlier multi-split waivers 

are identical in all relevant respects, 

except that AHRI 1230 allows the use of 

up to 12 indoor units, as opposed to 

eight in the earlier alternate test 

procedure. 

Second, ANSI/AHRI 1230–2010 

requires an additional test. The earlier 

alternate test procedure provides for 

efficiency rating of a non-tested 

combination in one of two ways: (1) at 

an energy efficiency level determined 

using a DOE-approved alternative rating 

method; or (2) at the efficiency level of 

the tested combination utilizing the 

same outdoor unit. In AHRI 1230, 

similar to the residential test procedure 

set forth in 10 CFR part 430, subpart B, 

appendix M, multi-split manufacturers 

must also test two or more combinations 

of indoor units with each outdoor unit. 

The first system combination is tested 

using only non-ducted indoor units that 

meet the definition of a tested 

combination. The rating given to any 

untested multi-split system combination 

having the same outdoor unit and all 

non-ducted indoor units is set equal to 

the rating of the tested system having all 

non-ducted indoor units. The second 

system combination is tested using only 

ducted indoor units that meet the 

definition of a tested combination. The 

rating given to any untested multi-split 

system combination having the same 

outdoor unit and all ducted indoor units 

is set equal to the rating of the tested 

system having all ducted indoor units. 

The rating given to any untested multisplit system combination having the 

same outdoor unit and a mix of nonducted and ducted indoor units is set 

equal to the average of the ratings for the 

two required tested combinations. 

Third, the alternate test procedure 

and AHRI 1230 require the use of 

different line lengths for the cooling 

refrigerant line when performing 

efficiency testing. AHRI 1230 requires 

longer line lengths depending on the 

type and capacity of the connected 

indoor units. 

As DOE continues to evaluate AHRI 

1230, DOE has granted manufacturers’ 

request to use AHRI 1230 as the 

alternate test procedure for testing and 

rating their commercial multi-split 

products subject to a waiver of DOE’s 

test procedures. DOE prescribed AHRI 

1230 as the alternate test procedure for 

those Daikin AC (Americas) Inc. 

(‘‘Daikin’’) commercial multi-split 

products that have cooling capacities 

less than or equal to 300,000 Btu/h, and 

for Carrier Corporation’s (‘‘Carrier’’) 

commercial multi-split products. 76 FR 

34685 (June 14, 2011); 76 FR 31951 

(June 2, 2011). 

Consistent with the requests of these 

other manufacturers, Mitsubishi 

requested that DOE permit it to use 

AHRI 1230 as the alternate test 

procedure to test and rate its WR2 and 

WY Series units and those S&L Class 

systems that have capacities less than or 

equal to 300,000 Btu/h. AHRI 1230 

covers multi-split products with cooling 

and heating capacities for outdoor units 

from 12,000 Btu/h to 300,000 Btu/h. The 

outdoor units of Mitsubishi’s WR2 and 

WY Series products fall within that 

range. Thus, similar to DOE’s decision 

in the Daikin and Carrier waivers, 

Mitsubishi requested that DOE prescribe 

AHRI 1230 as the alternate test 

procedure for Mitsubishi’s WR2 and WY 

Series products. 

Mitsubishi’s S&L Class product line 

includes outdoor units with individual 

capacities from 65,000 to 144,000 Btu/ 

h, which can be combined into systems 

with capacities from 130,000 to 480,000 

Btu/h. Although the individual 

capacities of these outdoor units fall 

within AHRI 1230’s capacity range, 

some of the combinations of outdoor 

units have capacities that are greater 

than the capacity range for AHRI 1230. 

Thus, similar to DOE’s decision in the 

Daikin waiver, Mitsubishi requested 

that DOE prescribe AHRI 1230 as the 

alternate test procedure for those S&L 

Class products that have capacities less 

than or equal to 300,000 Btu/h. For 

those S&L Class system that have 

capacities greater than 300,000 Btu/h, 

Mitsubishi will continue to use the 

alternate test procedure specified in the 

S&L Class waiver. 

DOE has determined that use of AHRI 

1230 is appropriate for Mitsubishi’s 

WR2 and WY Series products and its 

S&L Class products for the reasons set 

forth below. 

As discussed above, AHRI 1230 

requires longer line lengths for the 

cooling refrigerant line during testing, 

depending on the type and capacity of 

the connected indoor units. This 

difference affects the resulting energy 

efficiency determination. Testing 

according to AHRI 1230’s requirements 

provides a more conservative estimate 

of energy consumption because it 

results in a slightly lower efficiency 

rating than testing according to the 

alternate test procedure. 

In addition, the definition of ‘‘tested 

combination’’ in AHRI 1230 is more 

appropriate for these Mitsubishi 

products than the definition in the 

current alternate test procedure. As 

defined in the current alternate test 

procedures for Mitsubishi’s products, 

the ‘‘tested combination’’ of a VRF 

system is defined as one outdoor unit 

matched with between two and eight 

indoor units. The indoor units must 

represent the highest sales model 

family, and, together, must have a 

nominal cooling capacity that is 

between 95% and 105% of the nominal 

cooling capacity of the outdoor unit. 

Due to the relative size of some of 

Mitsubishi’s outdoor units and indoor 

units, permitting the matching of up to 

only eight indoor units may not be 

sufficient to comply with the 

requirement that the indoor units must 

have a combined capacity that is 


tkelley on DSK3SPTVN1PROD with NOTICES
Federal Register / Vol. 76, No. 205 / Monday, October 24, 2011 / Notices 65713 

between 95% and 105% of the nominal 

cooling capacity of the outdoor unit. 

AHRI 1230, as revised in March 2011, 

permits the use of up to twelve indoor 

units. For consistency purposes, DOE 

also agrees with Mitsubishi’s request 

that DOE amend the definition of 

‘‘tested combination’’ in the current 

alternate test procedure to make it 

identical to the definition in AHRI 1230 

for those units with capacities greater 

than 300,000 Btu/h that are outside the 

scope of AHRI 1230. 

For the reasons discussed above, and 

because DOE’s prescribed AHRI 1230 as 

the alternate test procedure in waivers 

granted to Carrier and Daikin, DOE 

determined that allowing Mitsubishi to 

use AHRI 1230 instead of the alternate 

test procedure provided in the WR2 and 

WY Series Waiver and the S&L Class 

Waiver is in the public interest. 

Conclusion 

After careful consideration of all the 

materials submitted by Mitsubishi, it is 

ordered that: 

(A)(1) Mitsubishi is not required to 

test the following equipment with 

cooling capacities of 300,000 Btu/h and 

below according to the test procedure 

for commercial package air conditioners 

and heat pumps prescribed by DOE at 

10 CFR 431.96 (ARI Standard 340/360– 

2004 (incorporated by reference in 10 

CFR 431.95(b)(2)-(3)), but instead shall 

use as the alternate test procedure 

ANSI/AHRI 1230–2010: 

(a) Equipment listed in the WR2 and 

WY Series waiver granted December 15, 

2009 (74 FR 66311); 

(b) Equipment listed in the S&L Class 

waiver granted December 15, 2009 (74 

FR 66315); and 

(c) Basic models of CITY MULTI WR2 

and WY Series and CITY MULTI S&L 

Class equipment listed in the waiver 

granted July 11, 2011 (76 FR 40714). 

(2) Mitsubishi shall be required to test 

the following equipment with cooling 

capacities above 300,000 Btu/h 

according to the test procedures for 

central air conditioners and heat pumps 

prescribed by DOE at 10 CFR 431.96, 

except that Mitsubishi shall test each 

model of outdoor unit with two or more 

combinations of indoor units. The first 

system combination shall be tested 

using only non-ducted indoor units that 

meet the definition of a tested 

combination as set forth in 

subparagraph (B). The second system 

combination shall be tested using only 

ducted indoor units that meet the 

definition of a tested combination as set 

forth in subparagraph (B). Mitsubishi 

shall make representations concerning 

the products covered in this waiver 

according to the provisions of 

subparagraph (C): 

(a) Equipment listed in the WR2 and 

WY Series waiver granted December 15, 

2009 (74 FR 66311); 

(b) Equipment listed in the S&L Class 

waiver granted December 15, 2009 (74 

FR 66315); and 

(c) Basic models of CITY MULTI WR2 

and WY Series and CITY MULTI S&L 

Class equipment listed in the waiver 

granted July 11, 2011 (76 FR 40714). 

(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 

waiver, the tested combination shall 

have the following features: The basic 

model of a variable refrigerant flow 

system (‘‘VRF system’’) used as a tested 

combination shall consist of an outdoor 

unit (an outdoor unit can include 

multiple outdoor units that have been 

manifolded into a single refrigeration 

system, with a specific model number) 

that is matched with between 2 and 12 

indoor units; for multi-split systems, 

each of these indoor units shall be 

designed for individual operation. 

(C) Representations. In making 

representations about the energy 

efficiency of its S&L Class and WR2 and 

WY Series multi-split products, for 

compliance, marketing, or other 

purposes, Mitsubishi must fairly 

disclose the results of testing under the 

DOE test procedure in a manner 

consistent with the provisions outlined 

below: 

(i) For multi-split combinations tested 

in accordance with this alternate test 

procedure, Mitsubishi may make 

representations based on those test 

results. 

(ii) For multi-split combinations that 

are not tested, Mitsubishi may make 

representations based on the testing 

results for the tested combination and 

that are consistent with one of the 

following methods: 

(a) Rating of non-tested combinations 

according to an alternative rating 

method approved by DOE; or 

(b) Rating of non-tested combinations 

having the same outdoor unit and all 

non-ducted indoor units shall be set 

equal to the rating of the tested system 

having all non-ducted indoor units. 

(c) Rating of non-tested combinations 

having the same outdoor unit and all 

ducted indoor units shall be set equal to 

the rating of the tested system having all 

ducted indoor units. To be considered a 

ducted unit, the indoor unit must be 

intended to be connected with ductwork 

and have a rated external static pressure 

capability greater than zero (0). 

(d) Rating of non-tested combinations 

having the same outdoor unit and a mix 

of non-ducted and ducted indoor units 

shall be set equal to the average of the 

ratings for the two required tested 

combinations. 

(D) This waiver amendment shall 

remain in effect from the date this 

Decision and Order is issued, consistent 

with the provisions of 10 CFR
