AHRI 570 (I-P) and 571 (SI): Performance Rating of Positive Displacement Carbon Dioxide Refrigerant Compressors and Compressor Units (Consolidated into AHRI 540-2020 (SI/I-P))
This standard applies to electric motor-driven, single and variable capacity, single and two-stage positive displacement refrigerant compressors and compressor units operating with carbon dioxide in subcritical and transcritical applications for refrigeration. It also applies to the presentation of performance data for positive displacement compressors and compressor units operating with carbon dioxide.
This standard has been consolidated into AHRI Standard 540-2020 (SI/I-P).
