In another optional embodiment, the target maximum air output can be determined according to the proportion of the air outlet in the open state. For example, when the number of the air outlet gears supported by the indoor adjusting part 10 is S, the total number of all the air outlets is N, and the number of the air outlets in the open state is N. At this time, the proportion of the outlets in the open state to the total number of all the outlets is P ═ N/N.

The first preset value is greater than the second preset value.
It should be understood that the temperature difference between the indoor ambient temperature and the set temperature may be obtained by subtracting a small value from a large value of the indoor ambient temperature and the set temperature. For example, in the heating mode, the temperature difference is obtained by subtracting the indoor ambient temperature from the set temperature; in the refrigeration mode, the temperature difference value is obtained by subtracting the set temperature from the indoor environment temperature.
Optionally, taking the target maximum air outlet gear as 3 gears (speed 3) as an example, the following describes in detail a switching scheme of the air outlet gear in an automatic wind scene in the heating process and the cooling process.

Indoor ambient temperature (Ti2) -set temperature (Ts2) ≥ 2 ℃: the air outlet gear is 3;
indoor ambient temperature (Ti2) -set temperature (Ts2) ≥ 1 ℃: the air outlet gear is 2;
indoor ambient temperature (Ti2) — set temperature (Ts2) <1 ℃: the air outlet gear is 1 gear.
As shown in fig. 3, in the case that the target maximum air outlet gear of the operation of the indoor adjusting part 10 is 3 gears, the following manner may be adopted to adjust the air outlet gear according to the temperature difference value.
Set temperature (Ts2) -indoor ambient temperature (Ti2) ≥ 2 ℃: the air outlet gear is 3;
