Abstract: The national mandatory standard GB 12021.9-2021 "Minimum allowable values of energy efficiency and energy efficiency grade of electric fan" has been released and will be implemented, the standard adds the type of "wind gathering fans" and puts forward new technical requirements for the energy efficiency of such fans. It introduces the characteristics and principles of concentrated fan, analyzes the factors affecting its air volume, and interprets the air volume test method and energy efficiency calculation method of concentrated fan. Make readers have a more comprehensive understanding of the new energy efficiency standards for electric fans, and provide reference for relevant design and development personnel.

Key words: Air circulation fans, Wind gathering, Air volume, Energy efficiency
