Embodiment
[0019] The experimental analysis method of the vibration characteristics of the frequency conversion air conditioner piping of the present invention comprises the following steps:
[0020] 1) Prepare the prototype for the experiment; prepare the chip for adjusting the frequency; the mass block and the damping block;
[0021] 2) By adjusting the frequency chip, the air conditioner can operate stably at every 2Hz frequency from the lowest frequency to the highest frequency in a wide frequency range under different operating conditions; in this embodiment, the frequency range is from f1 to f2.
[0022] 3) Test the vibration of the piping at each operating frequency and record it; re-test the vibration at each frequency point after adding a mass block to the piping and record it; add a damping block to the piping and then re-test each frequency The vibration situation of the point, and record;
