July 6, 2012: AHRI Publishes Standards Establishing Rating Method for CO2 Compressors

ARLINGTON, Va. — The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) announced the publication of standards 570 (I-P)-2012 and 571 (SI)-2012, Performance Rating of Positive Displacement Carbon Dioxide Refrigerant Compressors and Compressor Units, which AHRI stated provides for the first time a rating method for compressors and compressor units that use CO2 as a refrigerant.

“The publication of these standards is the result of nearly six years of effort on the part of AHRI and our members,” said Stephen Yurek, AHRI’s president and CEO. “Prior to publication, there was no available method to rate compressors that use CO2 as a refrigerant.”

These standards were developed by AHRI, in cooperation with the Association of European Refrigeration Component Manufacturers (ASERCOM) and the China Refrigeration and Air-Conditioning Industry Association (CRAA), as a way to harmonize the rating conditions with CO2 standards under development in Europe and China. Their publication will allow manufacturers in China, Europe, and the United States to evaluate performance and efficiency of equipment under the same conditions, to ensure consistency.

The standards can be downloaded for free at www.ahrinet.org/hvacr+industry+standards.aspx.

Publication date: 7/2/2012
