ARLINGTON, Va. — The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) recently published an industry-first standard for variable frequency drives (VFDs). As with all AHRI standards, 1210 (I-P)-2011 and 1211 (SI)-2011, Performance Rating of Variable Frequency Drives, are available for free on the AHRI website, 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 president and CEO.

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 certification program is expected to launch this summer and will include AHRI member companies ABB, Danfoss, Emerson Climate Technologies, Honeywell, Johnson Controls, McQuay International, Schneider-Electric, and Trane.
