As shown in Figure 2, the method comprises:
201: determine that the control model of air-conditioner is refrigeration mode.
202: judge whether the environment temperature of air-conditioner is more than or equal to the first temperature threshold.
If so, illustrate that air-conditioner is in overload operating mode, then perform step 203; If not, illustrate that air-conditioner is not in overload operating mode, then terminate.
It should be noted that, the concrete value of the present embodiment to " the first temperature threshold " does not limit, and can the factor such as ventilation effect of environment residing for air-conditioner determine.Optionally, the first temperature threshold can be 45 DEG C.
203: judge that whether the running status of air-conditioner is that low wind runs.
If not, then step 204 is performed; If so, then terminate.
Exemplary, the running status of air-conditioner can comprise: high wind runs, apoplexy is run and low wind runs, and running status can be specified by user.Often kind of running status and inner blower preset rotation speed is corresponding, and wherein, preset rotation speed can be a numerical value also can be a number range.After the running status of air-conditioner is determined, inner blower generally can run according to the preset rotation speed of inner blower corresponding to this running status.
It should be noted that, in order to prevent the phenomenon of inner blower stall from occurring, in air-conditioner, default minimum speed can be set.Usually, " preset minimum speed " and the preset rotation speed that low wind runs correspondence can be set to; Such as, or the value in the adjustable extent being benchmark with the preset rotation speed that low wind operation is corresponding, low wind runs corresponding preset rotation speed and adds 50r/min (rev/min) etc.According to the mode that above-mentioned setting " presets minimum speed ", think in the present embodiment: when the running status of air-conditioner is the operation of low wind, the rotating speed to inner blower can not be reduced; That is, when the judged result of step 203 is "Yes", then terminate.Wherein, the using method presetting minimum speed can with reference to the correlation step in the present embodiment.

Exemplary, " preset rotation speed amplitude of variation " can be a numerical value can be also a number range, can arrange based on experience value.Optionally, preset rotation speed amplitude of variation can be 50r/min (rev/min) etc.The size of preset rotation speed amplitude of variation during any twice this step 208 of execution can be the same or different.
It should be noted that, when the control model of air-conditioner is refrigeration mode, by reducing the rotating speed of inner blower, can evaporating pressure be reduced, thus reduce condensing pressure, reach the object of the load of unloading air-conditioner.
209: i-th second value obtaining the complete machine electric current of air-conditioner.
210: judge whether i-th the second value is greater than predetermined current threshold.
If so, then step 211 is performed; If not, then step 212 is performed.
211:i is from adding 1.
After performing step 211, perform step 206.
212: according to the second value and operating frequency f stable operation of compressor.
213: after air-conditioner stable operation Preset Time, be preset rotation speed by the current rotational speed regulation of the rotating speed of inner blower.
After performing step 213, perform step 202.
Exemplary, " Preset Time " can rule of thumb be arranged, and optionally, Preset Time can be 15min.
It should be noted that, " current rotating speed " when " current rotating speed " in step 213 is last execution step 206, " preset rotation speed " in step 213 is the preset rotation speed of " running status of the air-conditioner " correspondence in step 203.
