ISO/NP 26169

Rating of sound and vibration for positive displacement refrigerant compressors ISO/NP 26169

Scope

This proposed standard specifies normative references, terms and definitions, rating requirements, rating methods and minimum data requirements for published ratings of sound and vibration of positive displacement refrigerant compressors. This standard applies to positive displacement refrigerant compressors and their presentation of rating in air-conditioning, heating, refrigeration, and dehumidification applications. Single stage, two-stage, and refrigerant-injected compressors without intermediate temperature load (only one evaporator) are included in this standard. Subcritical operation and transcritical operation are included in this standard.
