Energy Efficiency Testing System for Electric Fans

1 The installation position of the table fan and floor fan test samples is fixed at a distance from the back wall1.5At the center of the meter, the height can be adjusted within a range of0-1.1Meter (referring to the height of the testing device plane from the ground).

2 Ordinary fan:

2.1 The anemometer device can move longitudinally as a whole, ensuring that the distance between the anemometer and the test sample is1.2Rice or1.5Meter (determined by the sweeping diameter of the tested fan).

2.2 4An anemometer from the center of the fan20mmAlong the diameter direction, towards4In one direction40mmThe increment moves outward.

2.3 Test each position for stopping1Minutes, sampling frequency2HzUse the average value as the wind speed at that point. Circular wind speed is the inner circle4Point and outer circle4Point (total)8The average wind speed of the point.

3 Tower fan and bladeless fan

3.1 adopt4An anemometer scans the air outlet plane of a tower fan or bladeless fan. The anemometer moves left and right on the bracket, and moves up and down on the bracket

4 Move the anemometer until the measured wind speed is below0.4rice/Second（24rice/The test stops in minutes. Automatically plan and calculate the test plane area.

5 The test anemometer is a blade type with a diameter of the impeller40mmfollowing, Measurement range of anemometer0.4-10rice/In seconds.
