This testing system uses energy efficiency values from reference standards IEC60879-2019, GB/T13380-2018, and GB12019-2008 "Energy Efficiency Limits and Grades for AC Fans" to measure the air volume and energy efficiency usage of the electric fan according to the requirements of GB/T13380-2018 "AC Fans and Speed Governors", and determines its qualification based on national standards; The testing system has the characteristics of accurate data, good repeatability, high efficiency, and convenient data storage

The testing system mainly consists of a room, a test screen, a control system, and an air volume acquisition system. It is controlled by a Japanese Mitsubishi PLC+industrial computer and displays and sets relevant test data through a 17 inch touch screen display It includes the movement distance, speed, test height, air volume, temperature/humidity, speed, voltage, current, power, etc. of the X, Y, and Z coordinate axes. The relevant test data has automatic saving and can be exported via USB
