Changes to Energy Test Procedures for Commercial ACs under Consideration

The U.S. Department of Energy has initiated a data collection process to consider whether to amend the current energy test procedures for three-phase commercial air-cooled air conditioners and heat pumps with a cooling capacity of less than 65,000 British thermal units per hour. Interested parties may submit input on this process by 3 December.

To inform interested parties and to facilitate this process, the DOE has gathered data identifying several issues associated with the currently applicable test procedures on which the agency is interested in receiving comment. The issues outlined in this document mainly concern three-phase commercial air-cooled ACs and heat pumps with a cooling capacity of less than 65,000 Btu/h and whether the test procedures and certification and compliance provisions for this equipment should align with those that apply to single-phase central ACs and heat pumps with rated cooling capacities of less than 65,000 Btu/h, as well as any additional topics that may inform the DOE’s decisions in a future test procedure rulemaking, including methods to reduce regulatory burden while ensuring the accuracy of the procedures.
