AMCA International Revises Air-Circulating-Fans Standard 230
Air Movement and Control Association International Inc. has published ANSI/AMCA Standard 230-23, Laboratory Methods of Testing Air Circulating Fans for Rating and Certification.
Superseding ANSI/AMCA Standard 230-15, ANSI/AMCA Standard 230-23 establishes uniform methods of laboratory testing air-circulating fans to determine performance for rating or certification purposes. It applies to electrically powered air-circulating fan heads with an input power greater than or equal to 125 W and ceiling fans. Excluded are:
- Jet fans as defined in ANSI/AMCA Standard 214-21, Test Procedure for Calculating Fan Energy Index for Commercial and Industrial Fans and Blowers
- Powered roof ventilators, induced-flow fans and laboratory exhaust fans
- Positive-pressure ventilators as defined in ANSI/AMCA Standard 240-22, Laboratory Methods of Testing Positive Pressure Ventilators for Aerodynamic Performance Rating
- Compressors
- Positive-displacement machines
ANSI/AMCA Standard 230-23 includes:
- Updated definitions related to air-circulating-fan classification
- Revised classification of air-circulating fans into three product groups: unhoused air-circulating fan head, housed air-circulating fan head and ceiling fan
- Clarification on the use of fan outlet area as opposed to fan discharge area with housed air-circulating fans
- The ceiling-fan-energy-index and thrust-efficiency-ratio metrics
- Clarified procedures for measuring fan speed
- 2021 errata to ANSI/AMCA Standard 230-15
- Equations for calculating fan total pressure, which is required to calculate CFEI
- A new annex (Annex C) defining subcategories of air-circulating fans.
Stakeholders for ANSI/AMCA Standard 230 are fan manufacturers, testing laboratories, fan engineers, fan equipment specifiers, HVAC professionals, energy-efficiency regulators, utility-incentive-program developers and building owners.
