This standard applies to modulating refrigerant mass flow positive displacement refrigerant compressors or compressor units operating in subcritical applications.  Liquid and vapor injection compressors will be covered in this standard.  This standard also applies to the presentation of performance data for positive displacement refrigerant compressors and compressor units for air-cooled, evaporative-cooled or water-cooled air-conditioning, heat pump and refrigeration applications.  The manufacturer is solely responsible for the determination of values to be used in published product information.  This standard only prescribes a description of the minimum amount of information to be provided and proscribes a method to be used to verify the accuracy of that information.

Project need:

The purpose of this standard is to establish, for variable refrigerant-mass-flow positive-displacement refrigerant compressors and compressor units: definitions, test requirements, rating requirements, minimum data requirements for Published Ratings, operating requirements, marking and nameplate data, and conformance conditions. This standard applies to electric-motor-driven, variable-refrigerant mass-flow, positive-displacement refrigerant compressors or compressor units. This standard also applies to the presentation of performance data for positive-displacement refrigerant compressors and compressor units for air-cooled, evaporative-cooled or water-cooled air-conditioning, heat-pump, and refrigeration applications.

Note: The information provided above was obtained by the Standards Council of Canada (SCC) and is provided as part of a centralized, transparent notification system for new standards development. The system allows SCC-accredited Standards Development Organizations (SDOs), and members of the public, to be informed of new work in Canadian standards development, and allows SCC-accredited SDOs to identify and resolve potential duplication of standards and effort.

Individual SDOs are responsible for the content and accuracy of the information presented here. The text is presented in the language in which it was provided to SCC.
