The U.S. Department of Energy has finalized new rules amending the test procedures for central air conditioners and heat pumps, incorporating updated industry standards. The changes include adding new cooling and heating efficiency measures, SCORE and SHORE, which factor in energy use during off modes. The rule updates various testing standards and clarifies the requirements for systems like dual-fuel heat pumps and those using newer refrigerants. These rules aim to provide more accurate efficiency ratings without increasing testing costs for manufacturers.
