Energy Conservation Program for Certain Industrial Equipment: Energy Conservation Standards and Test Procedures for Commercial Heating, Air-Conditioning, and Water-Heating Equipment

摘要

The U.S. Department of Energy (DOE) proposed to amend its energy conservation standards for several classes of commercial heating, air-conditioning, and water-heating equipment and to adopt new energy conservation standards for computer room air conditioners in a January 2012 notice of proposed rulemaking (January 2012 NOPR). The levels that DOE proposed to adopt were equivalent to the efficiency levels contained in the American National Standards Institute (ANSI)/ American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE)/Illuminating Engineering Society of North America (IESNA) Standard 90.1-2010 (ASHRAE Standard 90.1-2010). In addition, DOE proposed in the January 2012 NOPR to update the current Federal test procedures, or for certain equipment types adopt new test procedures, to incorporate by reference the most current versions of several relevant industry test procedures specified in ASHRAE Standard 90.1-2010. The amendments proposed in today's supplemental notice of proposed rulemaking (SNOPR) would modify the definition of "computer room air conditioner" initially proposed in the January 2012 NOPR and incorporate additional provisions to clarify the
