The air conditioner includes an indoor unit and an outdoor unit. The indoor unit comprises a shell and an indoor fan installed in the shell. The shell is provided with an air inlet and an air outlet. The air deflector is rotatably arranged at the air outlet. Optionally, the air deflection plate is a horizontal air deflection plate.
Indoor fan of air conditioner having maximum wind speed VmaxAnd minimum wind speed VminThat is, the indoor fan of the indoor unit has a maximum wind speed VmaxAnd minimum wind speed VminFor example, when the rotation speed of the indoor fan is maximum, the wind speed of the corresponding indoor fan is the maximum wind speed, and when the rotation speed of the indoor fan is minimum, the wind speed of the corresponding indoor fan is the minimum wind speed. Therefore, the air speed of the indoor fan can be adjusted by adjusting the rotating speed of the indoor fan.
The air deflector of the air outlet of the indoor unit of the air conditioner has a maximum opening degree and a minimum opening degree, and it can be understood that when the air deflector is in the maximum opening degree, the air volume of the air sent out from the air outlet is maximum, and when the air deflector is in the minimum opening degree, the air volume of the air sent out from the air outlet is minimum. That is, the opening degree of the air guide plate is adjusted to adjust the amount of air blown out from the outlet.
The operation process of the compressor can have a maximum operation frequency FmaxAnd a minimum operating frequency FminThat is, in the cooling operation, the maximum frequency that can be reached by the operation of the compressor is the maximum operation frequency, and the minimum frequency that can be reached by the operation of the compressor is the minimum operation frequency.
Specifically, the air conditioner has a no-wind mode, and it can be understood that the wind sent by the air conditioner has approximately no wind sense in the no-wind mode.

That is, in step S3, the air conditioner is continuously operated t1And detecting the indoor return air temperature T after min, and comparing the detected indoor return air temperature T with a preset value.
When T is more than or equal to T1When so, the air conditioner returns to step S2. That is, when T ≧ T1In the meantime, the air conditioner returns to step S2, and the indoor fan is operated at the maximum wind speed VmaxThe operation is carried out, the opening degree of the air outlet is the maximum opening degree, and the operation frequency of the compressor is the maximum operation frequency FmaxAnd the air conditioner is continuously operated t1min。
When T is2≤T＜T1In time, the wind speed V of the indoor fan is adjusted to x1% Vmax, reducing the operating frequency F of the compressor to F1And reaches F at the operating frequency of the compressor1Continuous operation t of rear air conditioner2And (5) min. That is, when T2≤T＜T1In time, the wind speed V of the indoor fan is reduced to x1% Vmax, reducing the operating frequency F of the compressor to F1And reaches F at the operating frequency of the compressor1Continuous operation t of rear air conditioner2And (5) min. Alternatively, t2The value range of (1) is 20-30. It will be understood that t2The value range of (A) can be adjusted according to actual needs.
When T is3≤T＜T2In time, the wind speed V of the indoor fan is adjusted to x2% Vmax, reducing the operating frequency F of the compressor to F2, and the air conditioner continuously operates for t3min after the operating frequency of the compressor reaches F2, wherein x1＞x2，F1＞F2. That is, when T3≤T＜T2In time, the wind speed V of the indoor fan is reduced to x2% Vmax, reducing the operation frequency F of the compressor to F2, and the air conditioner continuously operates t after the operation frequency of the compressor reaches F23And (5) min. Alternatively, t3The value range of (1) is 20-30. It will be understood that t3The value range of (A) can be adjusted according to actual needs.
When T is less than T3In the meantime, the wind speed V of the indoor fan is adjusted to the minimum wind speed VminAdjusting the opening degree of an air deflector of the air outlet to the minimum opening degree, and reducing the operation frequency F of the compressor to the minimum operation frequency FminAnd reaches F at the operating frequency of the compressorminContinuous operation t of rear air conditioner4And (5) min. That is, when T < T3In time, the wind speed V of the indoor fan is reduced to the minimum wind speed VminAdjusting the opening degree of an air deflector of the air outlet to the minimum opening degree, and reducing the operation frequency F of the compressor to the minimum operation frequency FminAnd reaches F at the operating frequency of the compressorminContinuous operation t of rear air conditioner4And (5) min. Alternatively, t4The value range of (1) is 20-30. It will be understood that t4The value range of (A) can be adjusted according to actual needs.
Here, it is understood that Fmin＜F2＜F1＜Fmax。
According to the control method of the air conditioner, the mute effect of the air conditioner and the comfort level of a user using the air conditioner are improved.
In some embodiments of the invention, in step S2, the indoor return air temperature T is detected, and when T ≧ T4When t is1More than or equal to 30 min; when T is less than T5When t is1Less than 10 min; when T is5≤T＜T4When t is 10 or less1Is less than 30 min. For example, the indoor return air temperature T is detected and compared with a preset value before the operation frequency of the compressor reaches the maximum operation frequency F in step S2, a timer is started when the operation frequency of the compressor reaches the maximum operation frequency, and the air conditioner is continuously operated at an operation time corresponding to the comparison result (for example, the indoor return air temperature T < T is detected before the operation frequency of the compressor reaches the maximum operation frequency F in step S2)5And when the running frequency of the compressor reaches the maximum running frequency, starting timing, and continuously running the air conditioner for 8 minutes). Of course, it will be appreciated that the indoor return air temperature T may also be detected in step S1, and when T ≧ T4When t is1More than or equal to 30 min; when T is less than T5When t is1Less than 10 min; when T is5≤T＜T4When t is 10 or less1＜30min。
Here, the detection of the indoor return air temperature in step S2 and the detection of the indoor return air temperature in step S3 are two independent detections.
Alternatively, T4＝T1，T5＝T2Thereby, the control method is facilitated to be simplified. Alternatively, T1The value range of (A) is 32-36 ℃, T2The value range of the (B) is 28-32 ℃.
