Wind speed time graph of the wind region under the measurement condition that air-conditioning internal machine 40 to be measured is currently run.
Sub-step S1042, the normal wind speed time graph according to the wind speed time graph relative to corresponding measurement condition
Fluctuation range judge whether that surge noise occurs, wherein, the normal wind speed time graph measures and is stored in test in advance
In main frame 10.
In the present embodiment, the normal wind speed information of each measurement condition can be tested in advance, and according to institute
Normal wind speed time graph corresponding to normal wind speed information generation is stated, and is stored in the test main frame 10.The test main frame
10 obtain its measurement condition for currently running from air-conditioning internal machine 40 to be measured, and according to the measurement condition of its operation from pre-stored pair
The normal wind speed time graph answered.Wind speed time graph corresponding to each air velocity transducer of generation and normal wind speed time is bent
Line is compared.When the wind speed time graph relative to the fluctuation range of the normal wind speed time graph no more than 10%,
Then judge not producing surge noise.When the wind speed time graph exists relative to the fluctuation range of the normal wind speed time graph
Between 10% to 30%, then judge to produce slight surge noise.When the wind speed time graph is relative to the normal wind speed
The fluctuation range of half interval contour then judges to produce obvious surge noise between 30% to 60%.When the wind speed time graph phase
For the normal wind speed time graph fluctuation range more than 60%, then judge to produce serious surge noise.
Step S105, the test main frame 10 generate test report according to judged result and the corresponding measurement condition.
In the present embodiment, test main frame 10 is generating test report corresponding to each measurement condition.It is alternatively possible to root
According to air-conditioning internal machine 40 to be measured in measurement condition running test main frame 10 to whether occur surge noise judged result give birth to
Into test report.To overhaul.
