The requirements of "Fan Energy Efficiency Limit and Energy Efficiency Rating" are for the convenience of writing and because the test method is basically the same, it can meet the air volume test requirements of table fans, table fans, and floor fans.

This test system is used to measure the energy efficiency value of AC fans in accordance with GB12019-2008 "AC Fan Energy Efficiency Limits and Energy Efficiency Ratings", and measure the air volume of electric fans in accordance with the requirements of GB/T13380-2007 "AC Fans and Speed Governors" And use value, and judge whether it is qualified according to national standards; ordinary air volume test device is operated by hand, the operator enters the test room, destroys the wind field, the accuracy of test data is low, and the test efficiency is also very low; this test system is mainly Using computer control, stepping motor drive, the operator is outside the test room, the personnel will not have an impact on the wind field, the equipment test work is completed automatically, and the test data is recorded, saved, and automatically generated air volume reports and energy efficiency ratings, with data Accuracy, good repeatability, high efficiency, and convenient data storage.

2.1 Main technical parameters

It can meet the air volume test requirements of table fans, bi fans, table fans, floor fans and ceiling fans

Laboratory size: 6000×4500×3000 Unit: mm

2.2 Main functions

Used to test wind speed, temperature, humidity, electrical parameters (voltage/current/power/power factor), speed and time

Principle of the test system:

The equipment is mainly composed of the air volume testing mechanical part and the computer control system. The equipment is installed in a L6000mmXW4500Xh3000mm test room. The air volume testing mechanism is as shown in the figure above. The sample platform can be manually raised and lowered to adjust the center height of the fan. The anemometer seat can be moved back and forth along the XY axis. The horizontal position of the anemometer and the fan sample can be adjusted by moving left and right. Its position is three times the diameter of the fan impeller. It is driven by a stepping motor. When the diameter of the fan is set, it will automatically move to the corresponding position; the left and right movement also uses steps. When the motor moves, its initial position is in the middle zero position. During the automatic test, the computer controls the stepping motor to move the left anemometer to the left 20mm to collect a wind speed value, while the right anemometer collects a wind speed value on the right 20mm sheet to complete a wind ring Wind speed test; then enter another wind ring (that is, left 60mm, right 60mm) to measure the wind speed value, each wind ring radius difference is 40mm, until the measured wind speed value is less than 24m/min
