SUPPLEMENTARY INFORMATION: In accordance with Title 10 of the Code of 
Federal Regulations (10 CFR 430.27(f)(2)), DOE gives notice of the 
issuance of its Decision and Order as set forth below. The Decision and 
Order grants GD Midea a waiver from the applicable test procedure in 10 
CFR part 430, subpart B, appendix M for specified basic models of 
central air conditioners and heat pumps, provided that GD Midea tests 
and rates such products using the alternate test procedure specified in 
the Decision and Order. GD Midea's representations concerning the 
energy efficiency of the specified basic models must be based on 
testing according to the provisions and restrictions in the alternate 
test procedure set forth in the Decision and Order, and the 
representations must fairly disclose the test results. Distributors, 
retailers, and private labelers are held to the same requirements when 
making representations regarding the energy efficiency of these 
products. (42 U.S.C. 6293(c))
    Consistent with 10 CFR 430.27(j), not later than January 8, 2019, 
any manufacturer currently distributing in commerce in the United 
States products employing a technology or characteristic that results 
in the same need for a waiver from the applicable test procedure must 
submit a petition for waiver. Manufacturers not currently distributing 
such products in commerce in the United States must petition for and be 
granted a waiver prior to the distribution in commerce of those 
products in the United States. Manufacturers may also submit a request 
for interim waiver pursuant to the requirements of 10 CFR 430.27.

Case #2017-013

Decision and Order

I. Background and Authority

    The Energy Policy and Conservation Act of 1975 (``EPCA''),\1\ 
Public Law 94-163 (42 U.S.C. 6291-6317, as codified), among other 
things, authorizes the U.S. Department of Energy (``DOE'') to regulate 
the energy efficiency of a number of consumer products and industrial 
equipment. Title III, Part B \2\ of EPCA established the Energy 
Conservation Program for Consumer Products Other Than Automobiles, 
which sets forth a variety of provisions designed to improve energy 
efficiency

[[Page 56066]]

for certain types of consumer products. These products include central 
air conditioners (CACs) and heat pumps (HPs), the focus of this 
document. (42 U.S.C. 6292(a)(3)) EPCA also requires the Secretary of 
Energy to prescribe test procedures that are reasonably designed to 
produce results that measure energy efficiency, energy use, or 
estimated operating costs during a representative average-use cycle, 
and that are not unduly burdensome to conduct. (42 U.S.C. 6293(b)(3)) 
The test procedure for CACs and HPs is contained in 10 CFR part 430, 
subpart B, appendix M.
---------------------------------------------------------------------------

    \1\ All references to EPCA in this document refer to the statute 
as amended through the EPS Improvement Act of 2017, Public Law 115-
115 (January 12, 2018).
    \2\ For editorial reasons, upon codification in the U.S. Code, 
Part B was re-designated as Part A.
---------------------------------------------------------------------------

    DOE's regulations set forth at 10 CFR 430.27 contain provisions 
that allow an interested person to seek a waiver from the test 
procedure requirements for a particular basic model when the 
petitioner's basic model for which the petition for waiver was 
submitted contains one or more design characteristics that either (1) 
prevent testing according to the prescribed test procedure, or (2) 
cause the prescribed test procedures to evaluate the basic model in a 
manner so unrepresentative of its true energy consumption 
characteristics as to provide materially inaccurate comparative data. 
10 CFR 430.27(a)(1). A petitioner must include in its petition any 
alternate test procedures known to the petitioner to evaluate the basic 
model in a manner representative of its energy consumption 
characteristics. 10 CFR 430.27(b)(1)(iii).
    DOE may grant a waiver subject to conditions, including adherence 
to alternate test procedures. 10 CFR 430.27(f)(2). As soon as 
practicable after the granting of any waiver, DOE will publish in the 
Federal Register a notice of proposed rulemaking to amend its 
regulations so as to eliminate any need for the continuation of such 
waiver. 10 CFR 430.27(l). As soon thereafter as practicable, DOE will 
publish in the Federal Register a final rule. Id.
    The wavier process also provides that DOE may grant an interim 
waiver if it appears likely that the petition for waiver will be 
granted and/or if DOE determines that it would be desirable for public 
policy reasons to grant immediate relief pending a determination on the 
underlying petition for waiver. 10 CFR 430.27(e)(2). Within one year of 
issuance of an interim waiver, DOE will either: (i) Publish in the 
Federal Register a determination on the petition for waiver; or (ii) 
publish in the Federal Register a new or amended test procedure that 
addresses the issues presented in the waiver. 10 CFR 430.27(h)(1). When 
DOE amends the test procedure to address the issues presented in a 
waiver, the waiver will automatically terminate on the date on which 
use of that test procedure is required to demonstrate compliance. 10 
CFR 430.27(h)(2).

II. GD Midea's Petition for Waiver: Assertions and Determinations

    By letter dated October 27, 2017, GD Midea filed a petition for 
waiver and an application for interim waiver from the applicable CAC 
and HP test procedure set forth in Appendix M.\3\ According to GD 
Midea, Appendix M does not include provisions for determining cooling 
intermediate air volume rate, cooling minimum air volume rate, and 
heating intermediate air volume rate for its variable-speed coil-only 
single-split systems. Consequently, GD Midea stated that it cannot test 
or rate these systems in accordance with the DOE test procedure. GD 
Midea stated that its variable-speed outdoor units are non-
communicative systems (i.e., the outdoor unit does not communicate with 
the indoor unit) for which compressor speed varies based only on 
controls located on the outdoor unit and the indoor unit maintains a 
constant indoor blower fan speed.
---------------------------------------------------------------------------

    \3\ On June 10, 2010, and June 20, 2018, GD Midea supplemented 
the list of basic models listed in its petition to confirm the 
manufacturer and individual model numbers of the paired indoor and 
outdoor units for which it seeks a waiver. The updated list of basic 
models is available at: https://www.regulations.gov/document?D=EERE-2017-BT-WAV-0060-0001.
---------------------------------------------------------------------------

    GD Midea seeks to use an alternate test procedure to test and rate 
specific CAC and HP basic models of its variable-speed coil-only 
single-split systems, which would specify the use of cooling full-load 
air volume rates as determined in section 3.1.4.1.1.c of Appendix M as 
cooling intermediate and cooling minimum air volume rates, and would 
specify the use of heating full-load air volume rates as determined in 
section 3.1.4.4.1.a of Appendix M as heating intermediate air volume 
rate.
    On May 30, 2018, DOE published a notice that announced its receipt 
of the petition for waiver and granted GD Midea an interim waiver. 83 
FR 24767. (``Notice of Petition for Waiver''). In the Notice of 
Petition for Waiver, DOE granted GD Midea's application for an interim 
waiver for specified basic models of CACs and HPs. In the Notice of 
Petition for Waiver, DOE stated that absent an interim waiver, the 
specified variable-speed coil-only single-split models that are subject 
of the waiver cannot be tested under the existing test procedure 
because Appendix M does not include provisions for determining certain 
air volume rates for variable-speed coil-only single-split systems. 83 
FR 24769. Typical variable-speed single-split systems have a 
communicating system, i.e., the condensing units and indoor units 
communicate and indoor unit air flow varies based on the operation of 
the outdoor unit. However, as presented in GD Midea's petition, its 
variable-speed outdoor units are non-communicative systems and the 
indoor blower section maintains a constant indoor blower fan speed.\4\ 
DOE also determined that the alternate test procedure suggested by GD 
Midea allows for the accurate measurement of efficiency of these 
products, while alleviating the testing problems associated with GD 
Midea's implementation of CAC and HP testing for the basic models 
specified in GD Midea's petition. Id.
---------------------------------------------------------------------------

    \4\ DOE reviewed public -facing materials (e.g., marketing 
materials, product specification sheets, and installation manuals) 
for the units identified in the petition, which supported GD Midea's 
assertion that the units are installed as variable-speed coil-only 
systems, in which the indoor fan speed remains constant at full and 
part-load operation.
---------------------------------------------------------------------------

    In the Notice of Petition for Waiver, DOE also solicited comments 
from interested parties on all aspects of the petition and the 
specified alternate test procedure. 83 FR 24770. In response, DOE 
received comments from the Natural Resources Defense Council 
(``NRDC''), Goodman Manufacturing Company, LP (``Goodman''), and 
Advanced Distributor Products, LLC (ADP).\5\
---------------------------------------------------------------------------

    \5\ The comments can be accessed at: https://www.regulations.gov/docket?D=EERE-2017-BT-WAV-0060.
---------------------------------------------------------------------------

    NRDC commented that it understood the issue identified by GD Midea 
with the current test procedure for GD Midea's products, but that it 
was concerned that the alternate test procedure suggested by GD Midea 
would overstate the energy efficiency of variable speed coil-only 
single-split systems. NRDC stated that in the field, it would expect 
these systems to modulate compressor speed to maintain a constant 
capacity regardless of outdoor ambient conditions. However, because the 
fan speed in the specified CACs and HPs is fixed, under test conditions 
the systems may deliver reduced capacity, but at a higher coefficient 
of performance (``COP''). NRDC states that this effect would be more 
pronounced with a slower compressor speed.
    In response to NRDC's comment, DOE notes that the DOE test 
procedure calls for adjusting the measured capacity and the total power 
input to account for the fan input power (see Appendix M, section 
3.3.d) using an adjustment that

[[Page 56067]]

is proportional to air volume rate. In the alternate test procedure, 
this adjustment remains constant because of the constant air volume 
rate. Consequently, the lower the capacity, the more the fan power 
adjustment reduces COP, contrary to NRDC's concern. The fan power 
adjustment is intended to reflect typical fan power of indoor fan 
motors in the field, with which coil-only indoor units would be paired. 
Hence, even if the COP is higher at a lower capacity, that COP would be 
consistent with the pairing of the indoor unit with a typical field air 
moving system. In addition, even though a system may be tested at 
minimum capacity, the seasonal energy efficiency ratio (SEER) and 
heating seasonal performance factor (HSPF) are calculated using the 
energy efficiency ratio (EER) and heating performance factor (HPF) for 
each temperature bin based on capacities matching conditioning loads 
representative for the temperatures (see, e.g., Appendix M section 
4.1.4.2, which provides a method to determine system EER when the 
system delivers capacity between minimum and maximum capacity). Thus, 
the alternate test procedure appropriately measures the energy 
efficiency of the GD Midea products subject to this waiver.
    Goodman stated the alternate test procedure should provide the 
exact same air volume rate for testing of both the cooling mode and 
heating mode, but it was not clear that the alternate test procedure 
accomplished this for heating mode.
    DOE notes that the air volume rates are the same for all tests 
under the alternate test procedure. As instructed in the alternate test 
procedure specified in the interim waiver and this Decision and Order, 
the heating intermediate air volume rate is the same as the heating 
full-load air volume rate determined in section 3.1.4.4.1.a of Appendix 
M. Section 3.1.4.4.1.a requires use of the cooling full-load air volume 
rate for full-load heating. Further, the heating minimum-load air-
volume rate is specified to be equal to the heating full-load air 
volume rate for ducted coil-only systems. Hence, air volume rates are 
the same for all operating conditions under the alternate test 
procedure, as recommended by Goodman.
    ADP agreed that the current test procedure does not allow for 
testing of variable-speed coil-only single-split systems, and that an 
alternate test procedure is needed. ADP suggested that to address other 
potential waiver requests, allowance should be made for different air 
volume rate settings, similar to the allowances in the current DOE test 
procedure for two-stage coil-only systems. ADP also expressed concern 
that GD Midea appeared to publish ratings in the AHRI certification 
database for the specified basic units prior to submission of the 
waiver request, and prior to being granted an interim waiver. ADP also 
noted that this also calls into question any compliance statement made 
to DOE about these products pursuant to 10 CFR 429.12(c). ADP further 
expressed concern regarding the length of time between the submission 
of the petition for waiver and the publication of the Notice of 
Petition for Waiver.
    DOE notes that a Decision and Order applies only to those basic 
models specified in the Order. The petition for waiver for GC Midea did 
not require DOE to consider or evaluate a test procedure that specifies 
different air volume rate settings such as that used in the current 
test procedure for two-stage coil-only systems. Accordingly, DOE is 
treating ADP's comment on this point to apply more generally than to 
the specific waiver request at issue. DOE will consider this issue in 
greater detail if it should decide to amend the CAC and HP test 
procedure in the future, or if it receives an application for a test 
procedure waiver for other basic models in which issues with different 
air volume rates are presented.
    DOE appreciates ADP's remaining comments regarding the timeframe of 
the waiver process and GD Midea's basic models appearing on the AHRI 
Certification Directory, but because they are outside the scope of the 
petition for waiver they will be considered separate from this Decision 
and Order.
    For the reasons explained here and in the Notice of Petition for 
Waiver, DOE understands that absent a waiver, the basic models 
identified by GD Midea in its petition cannot be tested and rated for 
energy consumption on a basis representative of their true energy 
consumption characteristics. DOE has reviewed the recommended procedure 
suggested by GD Midea and concludes that it will allow for the accurate 
measurement of the energy use of the products, while alleviating the 
testing problems associated with GD Midea's implementation of DOE's 
applicable CAC and HP test procedure for the specified basic models. 
Thus, DOE is requiring that GD Midea test and rate the specified CAC 
and HP basic models according to the alternate test procedure specified 
in this Decision and Order, which is identical to the procedure 
provided in the interim waiver.
    This Decision and Order applies only to the basic models listed and 
does not extend to any other basic models. DOE evaluates and grants 
waivers for only those basic models specifically set out in the 
petition, not future models that may be manufactured by the petitioner.
    GD Midea may request that the scope of this waiver be extended to 
include additional basic models that employ the same technology as 
those listed in this waiver. 10 CFR 430.27(g). GD Midea may also submit 
another petition for waiver from the test procedure for additional 
basic models that employ a different technology and meet the criteria 
for test procedure waivers. 10 CFR 430.27(a)(1).
    DOE notes that it may modify or rescind the waiver at any time upon 
DOE's determination that the factual basis underlying the petition for 
waiver is incorrect, or upon a determination that the results from the 
alternate test procedure are unrepresentative of the basic models' true 
energy consumption characteristics. 10 CFR 430.27(k)(1). Likewise, GD 
Midea may request that DOE rescind or modify the waiver if the company 
discovers an error in the information provided to DOE as part of its 
petition, determines that the waiver is no longer needed, or for other 
appropriate reasons. 10 CFR 430.27(k)(2).

III. Consultations With Other Agencies

    In accordance with 10 CFR 430.27(f)(2), DOE consulted with the 
Federal Trade Commission (``FTC'') staff concerning the GD Midea 
petition for waiver. The FTC staff did not have any objections to DOE 
granting a waiver to GD Midea for the specified basic models.

IV. Order

    After careful consideration of all the material that was submitted 
by GD Midea, the various public-facing materials (e.g., marketing 
materials, product specification sheets, and installation manuals) for 
the units identified in the petition, and the comments received in this 
matter, it is ORDERED that:
    (1) GD Midea must, as of the date of publication of this Order in 
the Federal Register, test and rate the GD Midea Heating & Ventilating 
Equipment Co., Ltd brand and Bosch Thermotechnology Corp brand single-
split CAC and HP basic models MOVA-36HDN1-M18M and MOVA-60HDN1-M18M 
(which contain individual combinations that each consist of an outdoor 
unit that uses a variable speed compressor matched with a coil-only 
indoor unit, and is designed to operate as part of a non-communicative 
system in which the compressor speed varies based only on controls 
located in the outdoor unit and the indoor blower unit maintains a

[[Page 56068]]

constant indoor blower fan speed), using the alternate test procedure 
set forth in paragraph (2):
    GD Midea basic models MOVA-36HDN1-M18M and MOVA-60HDN1-M18M include 
the following individual combinations, which do not specify a 
particular air mover, listed by brand name:

    (2) The alternate test procedure for the GD Midea basic models 
identified in paragraph (1) is the test procedure for CACs and HPs 
prescribed by DOE at 10 CFR part 430, subpart B, appendix M, except 
that as described below, for coil-only combinations: The cooling full-
load air volume rate as determined in section 3.1.4.1.1.c of Appendix M 
shall also be used as the cooling intermediate and cooling minimum air 
volume rates, and the heating full-load air volume rate as determined 
in section 3.1.4.4.1.a of Appendix M shall also be used as the heating 
intermediate air volume rate. All other requirements of Appendix M 
remain applicable.
    In 3.1.4.2, Cooling Minimum Air Volume Rate, include:
    f. For ducted variable-speed compressor systems tested with a coil-
only indoor unit, the cooling minimum air volume rate is the same as 
the cooling full-load air volume rate determined in section 
3.1.4.1.1.c.
    In 3.1.4.3, Cooling Intermediate Air Volume Rate, include:
    d. For ducted variable-speed compressor systems tested with a coil-
only indoor unit, the cooling intermediate air volume rate is the same 
as the cooling full-load air volume rate determined in section 
3.1.4.1.1.c.
    In 3.1.4.6, Heating Intermediate Air Volume Rate, include:
    d. For ducted variable-speed compressor systems tested with a coil-
only indoor unit, the heating intermediate air volume rate is the same 
as the heating full-load air volume rate determined in section 
3.1.4.4.1.a.
    (3) Representations. GD Midea may not make representations about 
the efficiency of the basic models identified in paragraph (1) of this 
Order for compliance, marketing, or other purposes unless the basic 
model has been tested in accordance with the provisions set forth above 
and such representations fairly disclose the results of such testing in 
accordance with 10 CFR part 430, subpart B, appendix M, as specified in 
this Order, and 10 CFR part 429, subpart B.
    (4) This waiver shall remain in effect according to the provisions 
of 10 CFR 430.27.
    (5) If GD Midea makes any modifications to the controls or 
configurations of these basic models, the waiver would no longer be 
valid and GD Midea would either be required to use the current Federal 
test method or submit a new application for a test procedure waiver. 
DOE may revoke or modify this 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

[[Page 56069]]

characteristics. 10 CFR 430.27(k)(1). Likewise, GD Midea may request 
that DOE rescind or modify the waiver if GD Midea discovers an error in 
the information provided to DOE as part of its petition, determines 
that the waiver is no longer needed, or for other appropriate reasons. 
10 CFR 430.27(k)(2).
    (6) Granting of this waiver does not release GD Midea from the 
certification requirements set forth at 10 CFR part 429.
