1 Introduction to Testing Device:

This air volume testing device is based onDOE 10 CFR Appendix U to subpart B of part 430 -2018The laboratory requirements specified in the new standard terms will meet the testing requirements of ceiling fan standards.

II Technical conditions:

1、Environmental temperature control:21.1±5℃, humidity50%.Therefore, it is recommended to install the test shielding room in a room with central air conditioning or install independent air conditioning, and control the temperature outside the shielding roombelow21.1℃This can ensure that the testing requirements are met. This plan does not include the temperature control part of the experimental environment.

2Installation device for ceiling fanCoaxial with the center of the ground rotation axis in the middle of the roof.

3Anemometer:12The wind speed probe is installed on a rotating arm that can rotate around the axis according to the standard installation position.

Device requirements:

1The device should comply withDOE 10 CFR Appendix U to subpart B of part 430 -2018The standard requirements for air volume testing include reasonable design, high degree of automation, convenient use, durability, load-bearing and anti vibration capabilities;

2Test scope: Ceiling fan(Customers only test ceiling fans)

It can automatically generate detection results and process curves, and print them out.

3Wind pressure anemometer, total12One. (Brand to be determined)The test results meet the requirements430standard）

4The system should be equipped with a multifunctional electricity meter that can measure voltage, current (true RMS), and power500VAVariable frequency (±)1%）Voltage regulating power supply, please refer to the configuration table for specific configuration;
