Airflow efficiency definition

Airflow efficiency means the ratio of airflow divided by power at a specific ceiling fan- speed setting expressed in cfm/watt.
Airflow efficiency means the ratio of airflow divided by power at a specific ceiling fan-speed setting expressed in CFM per watt (CFM/watt).3. Test Apparatus and General Instructions: The test apparatus and instructions for testing ceiling fans shall conform to the requirements specified in Chapter 3, ‘‘Air-Delivery Room Construction and Preparation,’’ Chapter 4, ‘‘Equipment Set-up and Test Procedure,’’ and Chapter 6, ‘‘Definitions and Acronyms,’’ of the EPA’s ‘‘ENERGY STAR Testing Facility Guidance Manual: Building a Testing Facility and Performing the Solid State Test Method for ENERGY STAR Qualified Ceiling Fans,’’ Version 1.1, December 9, 2002 (Incorporated by reference, see § 430.22). Record measurements at the resolution of the test instrumentation. Round off calculations to the same number of significant digits as the previous step. Round the final energy consumption value to the nearest whole number as follows:
