Specifically, the operation frequency of the compressor can be adjusted according to the difference between the current indoor return air temperature T1 and the target temperature Ts 0. Further, when the correction can be needed, in order to keep the inner fan damper matched with the operating frequency of the compressor, the inner fan damper can be controlled according to the difference between the current indoor return air temperature T1 and the target temperature Ts0, for example, in a refrigeration mode, when the inner fan damper is controlled according to the difference, the larger the difference is, the larger the corresponding rotating speed of the inner fan damper is, so that the inner fan damper is kept matched with the operating frequency of the compressor, and further, an unreasonable phenomenon in the operating process of the air conditioner is avoided, for example, when the operating frequency of the compressor is low, and the inner fan damper is in a gear which is not matched with the operating frequency, the wind leakage phenomenon of the inner fan may occur.

The rotating speed of the inner fan corresponding to the second gear is smaller than that of the inner fan corresponding to the first gear, the second temperature is smaller than the first temperature, and the first temperature and the second temperature can be determined according to a difference value delta Te between the current evaporation temperature Te and the target evaporation temperature Tes.
And S456, if the difference is greater than or equal to the third preset temperature, performing S457, and if the difference is less than the third preset temperature, performing S458.
And S457, controlling the inner fan to operate at a third gear, and correcting the target energy to be the target evaporation temperature from the current evaporation temperature. And the rotating speed of the inner fan corresponding to the third gear is less than that of the inner fan corresponding to the second gear.

It is understood that, referring to fig. 4, after the steps S453, S455, S457, S459, and S4511 are respectively performed, the current indoor return air temperature T1 of the air conditioner may be obtained to continue the subsequent inner fan wind gear control and possibly be corrected, and then the process may return to step S3.
It should be noted that, in this example, as shown in fig. 5, the relationship between the difference between the indoor return air temperature T1 and the target temperature Ts0 and the air conditioner energy correction factors a, b, c, d, e may be set, different differences may correspond to different energy correction factors, and the magnitudes of the first preset temperature, the second preset temperature, the third preset temperature, the fourth preset temperature and the fifth preset temperature may be sequentially decreased, for example, referring to fig. 5, the first preset temperature may be 4 ° f, the second preset temperature may be 2 ° f, the third preset temperature may be 0 ° f, the fourth preset temperature may be-2 ° f, and the fifth preset temperature may be-4 ° f. The relations between the correction-capable coefficients a, b, c, d and e and the difference value delta Te between the inner fan wind gear, the current evaporation temperature Te and the target evaporation temperature Tes are shown in Table 1.
Specifically, when the air conditioner operates in the cooling mode, a correction-required coefficient may be determined according to a difference between the indoor return air temperature T1 and the target temperature Ts0 and the first preset temperature, the second preset temperature, the third preset temperature, the fourth preset temperature and the fifth preset temperature with reference to fig. 5, then, a table 1 is looked up according to the correction-required coefficient to obtain an inner fan wind gear and a difference Δ Te corresponding to the correction-required coefficient, the current wind gear of the inner fan is adjusted to the inner fan wind gear corresponding to the correction-required coefficient, and the target energy is corrected from the current evaporation temperature to a sum of the target evaporation temperature and the difference Δ Te, that is, Tes + Δ Te, so as to improve the accuracy of the correction-required. Thus, in conjunction with Table 1, it is understood that the first temperature may be 2F and the second temperature may be 1F.
