Energy Conservation Program: Test Procedure for Room Air Conditioners

On June 11, 2020, the U.S. Department of Energy ("DOE") issued a notice of proposed rulemaking ("NOPR") to amend the test procedure for room air conditioners ("room ACs"). That proposed rulemaking serves as the basis for the final rule. Specifically, this final rule adopts the following updates to the test procedure for room ACs at appendix F: Incorporate by reference current versions of applicable industry standards; establish test provisions to measure energy use of variable-speed room ACs during a representative average use cycle; update definitions to define key terms and support provisions for testing variable-speed room ACs; and incorporate specifications and minor corrections to improve the test procedure repeatability, reproducibility, and overall readability. This final rule does not modify the test procedures for single-speed room ACs and does not affect the measured energy use for these models. The provisions established to measure energy use of variable-speed room ACs will improve the representativeness of the measured energy use of these models.
