SDHV Energy Efficiency Standards for America Act of 2011 - Amends the Energy Policy and Conservation Act (EPCA) to revise energy conservation standards for central air conditioners and central air conditioning heat pumps by requiring: (1) the seasonal energy efficiency ratio of small-duct, high-velocity systems to be no less than 11.00 for products manufactured on or after January 23, 2006; and (2) the heating seasonal performance factor of such systems to be 6.8 for products manufactured on or after such date.
Defines "small-duct, high-velocity systems" to mean a heating and cooling product that contains a blower and indoor coil combination that: (1) is designed for, and produces, at least 1.2 inches of external static pressure when operated at the certified air volume rate of 220-350 cubic feet per minute per rated ton of cooling; and (2) when applied in the field, uses high velocity room outlets generally greater than 1,000 feet per minute that have less than 6.0 square inches of free area.
Authorizes the Secretary of Energy (DOE) to amend by rule the standards established for such systems. Prohibits amended standards from taking effect less than five years after the final rule making the amendment is published. Requires the Secretary to determine whether standards for such systems should be amended no later than June 30, 2012.
