The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) and Zero Zone Inc., a manufacturer of refrigerated display cases and refrigeration systems, filed a petition with the U.S. Court of Appeals for the Seventh Circuit on May 27 asking the U.S. Department of Energy (DOE) to review its March 28 final rule, which revised the 2009 efficiency standards for certain commercial refrigeration equipment.
The rule includes maximum daily energy-consumption values as a function of either refrigerated volume or total display area for various equipment classes and “sets an efficiency level for these products that doesn’t even exist yet,” said Francis Dietz, vice president of public affairs for AHRI.
