The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) has published an industry-first standard for VFDs. As with all AHRI Standards, 1210 (I-P)-2011 and 1211 (SI)-2011, Performance Rating of Variable Frequency Drives, are available free of charge on AHRI’s website.
“What began in 2006 as a small group of members working toward a new Air-Conditioning and Refrigeration Institute (AHRI’s predecessor organization) product section has led to a standard that will level the playing field and lead to yet another world-class AHRI certification program,” said Stephen Yurek, AHRI’s president and CEO. Yurek added that the certification program is expected to launch this summer.
