Energy Efficiency Testing Room for DOE Qualified Ceiling Fans UL Standard Ceiling Fan Laboratory
Overview:
The ceiling fan energy efficiency test system is designed and manufactured according to the standard of " Office of Efficiency and Renewable Energy 10CFR Parts 429 and430 ", it can test the energy efficiency of high speed small diameter and low speed small diameter ceiling fans.
By testing four points' wind speeds of the sensors on the wind circle which diameter is >8”, the average wind speed of the wind circle is obtained, and the wind circle area is multiplied to calculate out the average wind volume. Finally, the wind volume of all the wind circles are added to calculate out the specific ceiling fan’s total wind volume, the total wind volume multiply by test time then divides the total value of energy consumption during testing plus standby energy consumption of the ceiling fan to determine the ceiling fan energy efficiency ratio. The formula is as following:
Standards:
