Updates to the Minimum Heating Efficiency Standards for Air-Cooled Air Conditioning and Heating Equipment [Heat Pumps]

Source: International Energy Agency
Last updated: 5 July 2024

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 Minimum Heating Efficiency Standards for Air Conditioning and Heating Equipment, specifically Heat Pumps, it does 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, which are enumerated in other policy entry. 

 

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

 

Air-Cooled:

Small Commercial Package Air Conditioning and Heating Equipment (3-Phase, Split-System) <65,000 Btu/h - HSPF = 8.2 - Compliance date: January 1, 2017.

Small Commercial Package Air Conditioning and Heating Equipment (3-Phase, Single Package) <65,000 Btu/h - HSPF = 8.0 - Compliance date: January 1, 2017.

Small Commercial Packaged Air Conditioning and Heating Equipment =65,000 Btu/h and <135,000 Btu/h

COP = 3.3 - Compliance date: January 1, 2018

COP = 3.4 - Compliance date: January 1, 2023.

Large Commercial Packaged Air Conditioning and Heating Equipment =135,000 Btu/h and <240,000 Btu/h

COP = 3.2 -  Compliance date: January 1, 2018

COP = 3.3 - Compliance date: January 1, 2023.

Very Large Commercial Packaged Air Conditioning and Heating Equipment =240,000 Btu/h and <760,000 Btu/h - COP = 3.2 - Compliance date: January 1, 2018

 

Small Commercial Package Air Conditioning and Heating Equipment (Water-Source: Water-to-Air, Water-Loop) <135,000 Btu/h - COP = 4.3 - Compliance date: October 9, 2015.
