Energy Conservation Program: Test Procedure for Room Air Conditioners;
Correction Office of Energy Efficiency and Renewable Energy, Department of Energy.
ACTION: Final rule; correction.
AGENCY:

On March 29, 2021, the U.S.
Department of Energy DOE
published a final rule adopting test procedures for room air conditioners hereafter the March 2021 final rule.
This document corrects errors and omissions in the Federal test procedure for room air conditioners as amended by the March 2021 final rule, including an incorrect mathematical notation and missing detail regarding the full compressor speed setpoint in the testing instructions. Neither the errors and omissions, nor the corrections in this document, affect the substance of the rulemaking or any conclusions reached in support of the final rule.
DATES: Effective May 7, 2021. The incorporation by reference of certain publications listed in the rule was approved by the Director of the Federal Register on April 28, 2021.

SUPPLEMENTARY INFORMATION:
I. Background DOE published a final rule in the Federal Register on March 29, 2021, establishing test procedures for room air conditioners in appendix F to subpart B
of Title 10 of the Code of Federal Regulations CFR part 430 appendix F. 86 FR 16446. Following publication of the March 2021 final rule, DOE
received a request on April 12, 2021
from the Association of Home Appliance Manufacturers to correct an error to a mathematical notation in the calculation for annual energy consumption in inactive and off mode.1
DOE reviewed the test procedure as amended and agrees that the mathematical notation as finalized in the March 2021 final rule is incorrect.
Upon review, DOE also identified an omission in the regulatory text as amended by the March 2021 final rule regarding a detail for the full compressor speed setpoint in the testing instructions. As discussed in the following paragraphs, the errors and omission in the regulatory text were correctly presented in the preamble to the March 2021 final rule. This correction rule revises appendix F to correct these typographical errors.
The appendix F test procedure specifies a formula to calculate annual energy consumption in inactive and off mode. Section 5.1 of appendix F.
However, the formula as established by the March 2021 final rule does not properly size one of the subscripts and inadvertently uses an incorrect mathematical notation. DOE is therefore fixing these issues in this notice, and notes that the ia in the Pia variable should be in subscript, and the addition symbol in the second parenthetical term should instead be a multiplication symbol. The parenthetical term refers to the annual energy consumption of the room air conditioner in off mode, in kilowatt-hours kWh per year, which is the product of the measured average power in off mode, Pom, in watts W, and the annual operating hours in off mode multiplied by a conversion factor 1 The Association of Home Appliance Manufacturers request is filed in the docket of this test procedure rulemaking Docket No. EERE2017

from watt-hours to kWh, tom, in kWh/W.
It would therefore be mathematically incorrect to sum Pom and tom to obtain an annual energy consumption term, rather than multiply the two variables.
The corrected equation is as follows:
AECia/om = Pia tia + Pom tom.
The March 2021 final rule amended appendix F to include a definition of full compressor speed full, which is referenced in the procedure for testing variable-speed room air conditioners. 86
FR 16446, 16477; see also section 2.12
of appendix F. Although the preamble to the March 2021 final rule stated that the full compressor speed is achieved when testing using a 75 F setpoint, that testing instruction was inadvertently omitted in the regulatory text. 86 FR
16446, 16456. Thus, DOE revises the definition for full compressor speed as discussed in the preamble of the March 2021 final rule as follows:
2.12 Full compressor speed full means the compressor speed at which the unit operates at full load test conditions, when using user settings with a unit thermostat setpoint of 75 F
to achieve maximum cooling capacity, according to the instructions in ANSI/
ASHRAE Standard 162016 Section 6.1.1.4.
II. Need for Correction As published, the regulatory text in March 2021 final rule may result in confusion due to the typographical errors and omission explained above.
Because this final rule would simply correct errors in the text without making substantive changes in the March 2021
final rule, the changes addressed in this document are technical in nature.
III. Procedural Issues and Regulatory Review DOE has concluded that the determinations made pursuant to the various procedural requirements applicable to the March 2021 final rule remain unchanged for this final rule technical correction. These determinations are set forth in the March 2021 final rule. 86 FR 16446, 16472.
Pursuant to the Administrative Procedure Act, 5 U.S.C. 553b, DOE has determined there is good cause to find that prior notice and opportunity for public comment on the changes contained in this document are impracticable, unnecessary, and
