The electric fan air volume testing system is built according to Appendix A of the national standard GB/T 13380-2015 "AC Fans and Governors", meeting the requirements of GB/T 13380-2015 "AC Fans and Governors" and GB 12021.9-2008 "Energy Efficiency Limits and Grades for AC Fans". For the convenience of walking, and because the testing methods are basically the same, it can meet the air volume testing requirements of table fans, wall fans, platform fans, floor fans, and ceiling fans Four anemometers are used to collect wind speed (two anemometers are added in the vertical direction on top of the original two horizontal anemometers on the test plane) to represent the average wind speed on the same ring.

4、 Technical conditions:

1. Environmental temperature control: 20 ± 5 ℃. Therefore, it is recommended to install the test shielding room in an air-conditioned room or install an independent air conditioner, and control the outdoor ground temperature of the shielding room to be below 20 ℃ to ensure that the testing requirements are met.

2. The distance between the center of the tested electric fan blades and the ground is 1200mm for table fans, wall fans, platform fans, top fans, and turning fans, and 1500mm for floor fans (when floor fans with a length of 4500mm or less are tested in a laboratory, their height is 1200mm);

3. The blade plane of the anemometer is parallel to the fan blades of the tested electric fan, with a distance of three times the diameter of the fan blades of the tested electric fan; Add a testing device positioning mechanism that can automatically locate;

4. The anemometer moves in two directions, left and right, along a horizontal line perpendicular to the axis of the fan blades in the test plane. The system is equipped with a laser beam for direct positioning of the anemometer, ensuring that the axis of the anemometer blades is always parallel to the axis of the electric fan blades. The installation mechanism of the anemometer should minimize the obstruction of airflow.
