Feb. 3, 2012: AHRI Publishes Industry Standard for Variable Frequency Drives

ARLINGTON, Va. — The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) has announced the publication of an industry-first standard for variable frequency drives (VFDs). As with all AHRI Standards, 1210 (I-P)-2011 & 1211 (SI)-2011, Performance Rating of Variable Frequency Drives, are available free of charge on AHRI’s website at www.ahrinet.org.

“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.

Once considered a high-tech option for only the most elaborate HVACR systems, VFDs have been in the mainstream for several years, providing better efficiency with improved reliability. VFDs produce fast-rising, high frequency pulses of electrical energy to control and power motors.

The VFD section includes the following member companies: ABB; Danfoss; Emerson Climate Technologies; Honeywell; Johnson Controls; McQuay International; Schneider-Electric; and Trane.
