Specifically, in a refrigeration mode, the return air temperature is corrected according to the opening angle of the air deflector, so that the return air temperature is increased; and in the heating mode, the return air temperature is corrected according to the opening angle of the air deflector, so that the return air temperature is reduced.

In order to improve the correction efficiency, different angle intervals can be set, each angle interval corresponds to one correction amount, and when the opening angle of the air deflector is located in a certain angle interval, the return air temperature is corrected according to the correction amount corresponding to the angle interval.

Similarly, in the heating mode, the amount of correction is performed on the return air temperature according to the opening angle of the air deflector, so that the return air temperature is reduced, and the method comprises the following steps: determining the correction quantity of the return air temperature according to the opening angle of the air deflector; wherein, the correction quantity is positively correlated with the opening angle of the air deflector; the return air temperature is corrected based on the correction amount.
