{"abstract":"The U.S. Department of Energy (\"DOE\" or \"the Department\") proposes to amend its test procedure for air-cooled, three-phase, small commercial package air conditioning and heating equipment with a cooling capacity of less than 65,000 British thermal units (\"Btu/h\") per hour and air-cooled, three-phase, variable refrigerant flow air conditioners and heat pumps with a cooling capacity of less than 65,000 Btu/h to incorporate by reference the latest version of the relevant industry test standard. DOE also proposes to adopt the seasonal energy efficiency ratio 2 (\"SEER2\") and heating seasonal performance factor 2 (\"HSPF2\") metrics specified by that industry test standard in the DOE test procedures for the three-phase equipment that is the subject of this notice of proposed rulemaking (\"NOPR\"). Additionally, DOE proposes to amend certain provisions for representations and enforcement to harmonize with single-phase products.","action":"Notice of proposed rulemaking and request for
