March 12, 2013: AHRI Files Comments on Rulemaking for Commercial Package A/C and Heating Equipment
AHRI said that, in its comments, it noted that the energy consumption of commercial package air conditioners has been significantly reduced over the past few years due to the implementation of design requirements in ASHRAE Standard 90.1. AHRI urged DOE to properly model these products to fully capture the energy savings that have been achieved since DOE last amended the energy conservation standards. Finally, AHRI cautioned DOE against switching to the IEER metric before addressing and resolving issues related to the alternative efficiency determination method (AEDM), the basic model definition, and the uncertainty in testing measurements due to the use of part-load metrics.
