After the wind speed variation is obtained through calculation, the wind speed of the indoor fan of the air conditioner is adjusted according to the variation direction, namely, the wind speed is adjusted according to the variation on the basis of the current wind speed of the indoor fan. For example, if the calculated wind speed variation is 20% and the adjustment direction is increased, the wind speed is increased by 20% based on the current wind speed.

and step S70, when the adjusted wind speed is larger than the determined wind speed limit value, adjusting the wind speed of the indoor fan of the air conditioner according to the wind speed limit value.
The difference between the present embodiment and the above embodiments is that a preset interval is set, the wind speed adjustment in the preset interval is different from the adjustment in other sense-of-mind intervals, and the wind speed adjustment in the preset interval needs to be limited. The preset interval is a sense-of-fit interval of 3, and can also be other sense-of-fit intervals obtained according to experiments. The specific wind speed regulation control refers to table 6.
Interval 3 continuous running time JSX _ MAX value
ucSectionTim<30 minutes after 80%
30 minutes<ucSectionTim<60 minutes after 60%
60 minutes<ucSectionTim<90 minutes after 40%
90 minutes<ucSectionTim<120 minutes ═ 120 minutes 20%
120 minutes<ucSectionTim 1%
TABLE 6
And when the adjusted wind speed is greater than the determined wind speed limit value, adjusting the wind speed of the indoor fan of the air conditioner according to the wind speed limit value. Specifically, the wind speed limit is associated with the running time ucsectortim of the sensilla zone 3, for example, ucsectortim < 30 minutes, and the maximum wind speed limit is 80%; the maximum wind speed value is limited to 40% at 60 minutes < ucsectortim > -90 minutes. And when the adjusted wind speed is less than or equal to the determined wind speed limit value, adjusting the wind speed of the indoor fan of the air conditioner according to the wind speed variation, namely adjusting the wind speed of the indoor fan according to the actually calculated wind speed variation. The preset personal feeling interval is a comfortable interval, and cannot be adjusted greatly at present, so that adjustment of the wind speed needs to be limited.
