Federal Register / Vol. 86, No. 158 / Thursday, August 19, 2021 / Rules and Regulations
No. 19, at p. 1 PG&E, SCE, SDG&E
commented that including the terms commercial and industrial with fan would limit confusion with residential products, i.e., circulating fans and furnace fans. PG&E, SCE, SDG&E, No.
17, at p. 2 CTI generally supported the adoption of the AMCA 21421
definition of fan as the definition for commercial and industrial fans but asserted that the definition was unclear as to which fans would fall within DOEs scope of coverage. CTI explained that they were neutral on the term commercial and industrial to further describe fans, but expressed concern with the fans that could fall under such descriptor. In addition, CTI expressed concerns that embedded fans were not explicitly excluded from the scope of AMCA 21421, only its foreword, and thought that embedded fans should be specifically excluded from the scope of AMCA 21421. CTI, No. 13, pp. 12
AMCA recommended that ceiling fans and furnace fans be explicitly excluded from the scope of any potential DOE
regulation because of the existing regulations of those products. AMCA, No. 12, at p. 3
While generally supporting use of the AMCA 21421 definition as the DOE
definition for fan, AHRI expressed that commercial and industrial had a special meaning not identical to the 21421 definition of fan and that hat required further elaboration by DOE.
AHRI recommended that the definition for commercial and industrial fan needs to make clear that fans within scope are industrial equipment, including commercial fans per 42 U.S.C.
63112, and exclude ceiling fans, furnace fans, and fans embedded in other consumer products. AHRI, No.
16.2, at p. 2. AHRI also suggested a definition for commercial and industrial fans that would exclude equipment that utilizes single-phase electricity and exclude equipment with a rated fan shaft power less than or equal to 1 hp or fan electrical input power above 0.89 kilowatts, and listed specific equipment categories containing fans for which AHRI
recommends exclusions AHRI, No.
16.1, at p. 1; 16.2, at pp. 2, 3. AHRI
asserted that collectively these exclusions would be consistent with the scope of the AMCA 21421 test procedure, the scope of the test procedure as recommended in the petition presented in the April 2020
Notice of Petition, and the scope of the test procedure and energy conservation standards as recommended by the Working Group. AHRI also expressed concern that manufacturers of DOE

regulated equipment that contain commercial and industrial fans would be subject to double regulations. AHRI, No. 16.2, at p. 3. Ebm-pabst, while stating its support of the AMCA 21421
fan definition for use in DOEs coverage determination, also suggested that furnace fans and ceiling fans, as defined in 10 CFR 430.2, should be specifically excluded in the commercial and industrial fan definition and commented that fans operating at three-phase or rated at greater than 127 volts would typically be considered as commercial and industrial fans ebm-papst, No. 19, at p.1. MEP recommended that the definition for a commercial and industrial fan should include a requirement for polyphase electric current with a fan shaft power greater than 3 hp, to avoid including residential fans in regulations. MEP, No. 15, at p. 1. AMCA commented that the scope of any potential DOE
regulation should be based on a lower shaft power limit of 1 horsepower to align with ASHRAE 90.12019 and the 2021 International Energy Conservation Code. AMCA, No.12, at p. 3
While generally supporting use of the AMCA 21421 definition as the DOE
definition for fan, Greenheck recommended establishing a separate definition for fans that are embedded in a manufactured assembly where the assembly includes functions other than air movement require further definition that considers the utility, function and overall energy consumption and efficiency of the manufactured assembly. Greenheck, No. 18, p. 1 MEP
also recommended that DOE establish a separate definition for embedded fans as provided by AMCA 21421 and to make clear that embedded fans are not included in the definition of fans.
MEP, No. 15, at p. 1 CTI commented that the majority of fan energy savings derive from standalone fans as opposed to embedded fans. CTI commented that an exemption for fans used in heat rejection equipment is appropriate because the overall performance of the heat rejection equipment is the key metric and not the performance of the individual fan component. CTI, No. 13, at p. 2
In response to the April 2020 Notice of Petition, DOE received a number of comments relevant to the scope of the determination. AHRI commented that DOE should initiate a new coverage determination process and that the final scope of coverage should be limited to stand-alone fans. AHRI commented that HVACR and water heating equipment is built, tested, rated, and certified as a completed design; and that modifying a

component, including fans, would change the performance of the equipment. AHRI commented that energy conservation standards could create a safety issue for replacement fans in equipment to the extent that compliance with safety and performance standards could be affected by a change in the fan performance.
Docket No. EERE2020BTPET0003;
AHRI, No. 14 at p. 3 22 Daikin commented in support of AHRIs comment. Docket No. EERE2020BT
PET0003; Daikin, No. 8 at p. 1 Lennox similarly opposed regulating fans that are components of HVACR equipment.
Docket No. EERE2020BTPET0003;
Lennox, No. 5 at pp. 23
In response to the April 2020 Notice of Petition, Johnson Controls commented in support of initiating a coverage determination for commercial and industrial fans and blower products within the same scope and noted exemptions of the petition by AMCA, the Air Conditioning Contractors of America, and the Sheet Metal & Air Conditioning Contractors of America.
Johnson Controls commented that they strongly oppose any regulatory measures aimed at fans that are components of heating, ventilation, and air conditioning HVAC equipment where the primary purpose of the equipment is to heat or cool a space, and for which there are already wellestablished equipment-level energy efficiency. Docket No. EERE2020BT
PET0003; Johnson Controls, No. 10 at p. 1
In this final rule, DOE is no longer including the description commercial and industrial with the term fan, since DOE has determined that this language is redundant, given the statutory definition of industrial equipment in 42 U.S.C. 63112. In addition, as noted above, comments also raised questions as to whether including commercial and industrial would provide more clarity or provoke more uncertainty. The definition of industrial equipment explicitly excludes covered products, other than a component of a covered product. 42
U.S.C. 63112Aiii Therefore, the inclusion of commercial and industrial is not necessary to clarify the exclusion of ceiling fans and furnace fans, both covered products defined at 10 CFR 430.2.
While fans would typically operate on three-phase power and not on singlephase power, this criterion does not necessarily distinguish a fan as industrial equipment, because some 22 As previously discussed, AHRI repeated these arguments in response to the May 2021 RFI.
