This notice publishes the U.S. Department of Energy's (DOE) decision and order in Case No. CAC-028. 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 Title 10 of the Code of Federal Regulation (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.
