Electric Fan Airflow Laboratory

Purpose:according toBS EN IEC 60879:2019TheGB/T13380-2015Technical specification requirements：

1Scope of application (applicable standards)

The requirements for this air volume testing device are based on, for the convenience of walking, and because the testing methods are basically the same,Can meet the air volume testing requirements for table fans, wall fans, floor fans, and column 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.

2 Main technical parameters and functions

2.1 Main technical parameters

Can meetTable fan, Bi fan, floor fanRequirements for air volume testing

Laboratory size:(Small fan)4500*4500*3000）Unit: mm

2.2 Main functions

Used for testing wind speed, temperature, humidity, and electrical parameters (voltage)/current/power/Power factor, speed, and time
