DOE Sets New Energy Efficiency Test Procedure for Portable Air Conditioners

The Energy Department is setting new energy efficiency test procedures for portable air conditioners, in a final rule (here). The new test procedures apply to any “portable encased assembly, other than a packaged terminal air conditioner, room air conditioner, or dehumidifier, that delivers cooled, conditioned air to an enclosed space, and is powered by single-phase electric current,” including single-duct and dual-duct portable air conditioners. DOE recently determined portable air conditioners are covered by energy efficiency requirements, though the agency has not yet set a standard. Compliance with the new test procedures is required for any representations made on or after Nov. 28.
