The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) publishes standards 570 (I-P)-2012 and 571 (SI)-2012, Performance Rating of Positive Displacement Carbon Dioxide Refrigerant Compressors and Compressor Units, providing 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."
AHRI developed the standards 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, thereby ensuring consistency.
AHRI expressed appreciation to several members whose work was invaluable to the effort:
* Peter Narreau, Bitzer U.S. Inc.
* Herman Renz, Bitzer U.S. Inc.
* Steve Holden, Carrier Corp.
* John Galyen, Danfoss
* Rajan Rajendran, Emerson Climate Technologies.
