IEC60879 Electric Fan Airflow Laboratory Table Fan Floor Fan Airflow Energy Efficiency Laboratoryaccording toGB12021.9-2008, GB/T 13380-2018 standard testing requirements Wind speed and volume of electric fan

Technical specification requirements:

1 Scope of application (applicable standards)

This air volume testing device is based on the national standardGB/T 13380-2018Appendix to AC Fans and GovernorsABuilt to meetGB/T 13380-2018AC Fans and GovernorsGB 12021.9-2008The requirements of the "Energy Efficiency Limit Values and Energy Efficiency Grades for AC Fans" are for the convenience of walking, and because the testing methods are basically the same,Can meet the air volume testing requirements for table fans, Bi fans, platform fans, floor fans, and ceiling fans.Four anemometers are used to collect wind speed (the test plane has existing ones)2On the basis of a horizontal anemometer, an increase is made in the vertical direction2An anemometer is used to represent the average wind speed on the same ring. The test schematic diagram is shown in the figure:
