Department of Energy June 30, 2015 – Federal Register Recent Federal Regulation Documents

On March 13, 2014, the U.S. Department of Energy (DOE) issued a notice of proposed rulemaking (NOPR) to amend the test procedures for packaged terminal air conditioners (PTACs) and packaged terminal heat pumps (PTHPs). That NOPR serves as the basis for this final rule regarding the test method for PTACs and PTHPs. The amendments adopted here do not affect measured energy use. These changes incorporate by reference certain sections of the latest versions of industry test procedures AHRI Standard 310/380-2014, ANSI/ASHRAE Standard 16-1983 (RA 2014), ANSI/ASHRAE Standard 37-2009, and ANSI/ASHRAE Standard 58-1986 (RA 2014), and specify additional testing provisions that must be followed including an optional break-in period, require that cooling capacity tests be conducted using electricity measuring instruments accurate to +/- 0.5% of reading, explicitly require that wall sleeves be sealed, allow for the pre-filling of the condensate drain pan, and require testing with 14-inch deep wall sleeves and the filter option most representative of a typical installation.
