Compensating rotational speed adjusts the rotating speed of indoor fan 120, to make up horizontal air ducting 151 and after longitudinal air ducting 152 offsets
Because resistance increases to the influence of the air-supply air quantity of air outlet 140, thus no matter horizontal air ducting 151 and longitudinal air ducting
152 run to where, can guarantee that air-conditioner is run with constant air quantity, so as to be effectively guaranteed the refrigeration of air-conditioner
Heating effect and comfortableness.
It is that the control method of the air-conditioner of the present embodiment permanent wind amount is further illustrated, is come with specific operating process below
Illustrate：
When horizontal air ducting 151 is in middle position A0（Maximum air-out position）, longitudinal air ducting 152 is in most
When the standard working speed Nb of air-out position B0, and indoor fan 120 greatly is 1200rpm, the air-supply air quantity Qmax of air outlet 140
It is 600 M3/H；Horizontal stepper motor 161 controls horizontal air ducting 151 to be displaced to left-most position A1 by middle position A0
When, the step number Lz of the operating of horizontal stepper motor 161 is 50 steps, and now the air-supply air quantity Qz of air outlet 140 is 570 M3/ H, that is, send
The change of wind air quantity turns to 30 M3/H；Horizontal stepper motor 161 controls horizontal air ducting 151 to be displaced to by middle position A0
During right-most position A2, the step number Ry of the operating of horizontal stepper motor 161 is 60 steps, and now the air-supply air quantity Qy of air outlet 140 is
560 M3The change of/H, i.e. air-supply air quantity turns to 40 M3/H；Longitudinal stepper motor 162 controls longitudinal air ducting 152 to be gone out by maximum
When wind position B0 is displaced to uppermost position B1, the step number Us of the operating of longitudinal stepper motor 162 is 40 steps, now air outlet 140
Air-supply air quantity Qs be 575 M3The change of/H, i.e. air-supply air quantity turns to 25 M3/H；Longitudinal stepper motor 162 controls longitudinal wind-guiding to fill
When putting 152 and being displaced to lowermost position B2 by maximum air-out position B0, the step number Dx of the operating of longitudinal stepper motor 162 is 50 steps,
Now the air-supply air quantity Qx of air outlet 140 is 565 M3The change of/H, i.e. air-supply air quantity turns to 35 M3/H。
After air-conditioner is opened, horizontal stepper motor 161 control horizontal air ducting 151 by middle position BO to the left
During skew, if the step number L that horizontal stepper motor 161 is rotated is 30 steps, the compensating rotational speed Ncz=(Nb/ of indoor fan 120
Qmax) * (Qmax-Qz) * (L/Lz)=(1200/600) * (600-570) * (30/50)=36rpm, analysis and processing module 171 is led to
The rotating speed that control module 172 adjusts indoor fan 120 is crossed, makes the current rotating speed Ns=1200+36=1236rpm of indoor fan 120,
It is 30 that the current rotating speed Ns operatings of indoor fan 120 with 1236rpm can make up the step number L rotated in horizontal stepper motor 161
Horizontal air ducting 151 offsets the wind loss for bringing to the left during step.
When horizontal stepper motor 161 controls horizontal air ducting 151 to be offset to the right by middle position BO, if laterally step
