{"abstract":"The U.S. Department of Energy (\"DOE\") proposes to amend the test procedure for variable refrigerant flow multi-split air conditioners and heat pumps (\"VRF multi-split systems\") to incorporate by reference the latest version of the industry test standard. DOE also proposes to adopt the integrated energy efficiency ratio metric in its test procedures for VRF multi-split systems. Additionally, DOE proposes to adopt provisions in the updated industry test procedure relevant to certification and enforcement, including a controls verification procedure. DOE welcomes written comment from the public on any subject within the scope of this document (including topics not specifically raised in this proposal), as well as the submission of data and other relevant information.","action":"Notice of proposed rulemaking and request for comment.","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/2021/12/10/2021-26288.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"429","title":10},{"chapter":null,"citation_url":null,"part":"431","title":10}],"citation":"86 FR 70644","comment_url":null,"comments_close_on":"2022-02-08","correction_of":null,"corrections":[],"dates":"Comments: DOE will accept written comments, data, and information regarding this notice of proposed rulemaking (NOPR) on or before February 8, 2022.
