{"abstract":"This final rule amends the test procedure for variable refrigerant flow (\"VRF\") multi-split air conditioners and heat pumps (\"VRF multi-split systems\") to incorporate by reference the latest version of the applicable industry test standard. This final rule also adopts the integrated energy efficiency ratio metric in its test procedures for VRF multi-split systems. Additionally, this final rule adopts provisions in the updated industry test procedure relevant to certification and enforcement, including a controls verification procedure.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF ENERGY","name":"Energy Department","id":136,"url":"https://www.federalregister.gov/agencies/energy-department","json_url":"https://www.federalregister.gov/api/v1/agencies/136","parent_id":null,"slug":"energy-department"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2022/10/20/2022-22511.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"429","title":10},{"chapter":null,"citation_url":null,"part":"431","title":10}],"citation":"87 FR 63860","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"The effective date of this rule is November 21, 2022.
