Step 11：Air conditioner heat-production is run, and is obtained the real-time rotating speed of indoor fan, is made comparisons with reference rotation velocity.
The real-time rotating speed of indoor fan refers to being obtained according to certain sample frequency in air conditioner heat-production operational process
The rotating speed of indoor fan.The rotating speed of indoor fan is controlled by controller of air conditioner, and therefore, controller can easily be got
Real-time rotating speed.Reference rotation velocity be reflection room air circulation whether a sufficient tachometer value, can be known, prestore
Fixed value, a value can also being determined according to some other real-time parameter, corresponding with real-time rotating speed.
In some preferred embodiments, the real-time wind-guiding of indoor unit wind deflector of the reference rotation velocity corresponding to real-time rotating speed
One value of angle-determining.Specifically, when air conditioner heat-production is run, the real-time wind-guiding angle of indoor unit wind deflector is also obtained
Degree.The wind-guiding angle of wind deflector is controlled by controller of air conditioner, and therefore, controller also can easily get wind deflector
Real-time wind-guiding angle.After the real-time wind-guiding angle for obtaining indoor unit wind deflector, real-time wind-guiding angle and wind deflector are calculated

[0 °, 5 °), corresponding correction factor is 100%；Misalignment angle be [5 °, 10 °), corresponding correction factor be 105%；Misalignment angle
Ranging from [10 °, 20 °), corresponding correction factor is 115%；Misalignment angle be [20 °, 30 °), corresponding correction factor is
130%；Misalignment angle is more than or equal to 30 °, and corresponding correction factor is 140%.Get the real-time wind-guiding angle of indoor unit wind deflector
Degree is 60 °, then, the misalignment angle of real-time wind-guiding angle and default wind-guiding angle is 15 °.According to above-mentioned misalignment angle and amendment
The correspondence of coefficient is it is found that corresponding correction factor is 115%.Determine that reference turns according to misalignment angle and preset reference rotating speed
Speed is specifically reference rotation velocity according to the rotating speed that the product of reference rotation speed and correction factor is determined.Assuming that reference rotation speed
For r0, then reference rotation velocity r=115%*r0.In this embodiment, at least misalignment angle be 0 ° when, correction factor 1, with reference to turn
Speed is equal with preset reference rotating speed.
