This notice publishes the U.S. Department of Energy's (DOE) decision and order in Case No. CAC-024. DOE grants a waiver to Daikin from the existing DOE test procedure applicable to residential central air conditioners and heat pumps. The waiver request is specific to the Daikin Altherma air-to-water heat pump with integrated domestic water heating. The test method for central air conditioners and heat pumps contained in 10 CFR part 430, subpart B, appendix M does not include any provisions to account for the operational characteristics of an air-to-water heat pump, or any central air-conditioning heat pump with an integrated domestic hot water component. As a condition of this waiver, Daikin must test and rate its Altherma heat pump products according to the alternate test procedure set forth in this notice.
