Updates to the Minimum Cooling Efficiency Standards for Air Conditioning and Heating Equipment

Last updated: 9 June 2020

The code (10 CFR § 431.97 - Energy efficiency standards) defines energy efficiency ratio and combined energy efficiency ratio of commercial air conditioners and heat pumps.

 

Hereafter the Minimum Cooling Efficiency Standards for Air Conditioning and Heating Equipment will be enumerated, this foes not include single package vertical air conditioners and single package vertical heat pumps, packaged terminal air conditioners and packaged terminal heat pumps, computer room air conditioners, variable refrigerant flow multi-split air conditioners and heat pumps, and double-duct air-cooled commercial package air conditioning and heating equipment. These are enumerated in other policy entries.

 

The compliance date varies across different equipment and it is thus specified next to the relative standers. Compliance dates have to be intended as the date equipment manufactured after which need to comply with the standard.
