Over the years, frequency converters have become integral to energy saving in HVAC/R applications. The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) recently announced the availability of AHRI Standard 1210 (I-P)-2011 & 1211 (SI)-2011, Performance Rating of Variable Frequency Drives, which provides specific criteria for efficiency, harmonics and motor stress in variable frequency drive (VFD) products. This industry-first standard will allow customers to compare products from major suppliers on equal terms.
