Step S102: judging whether the environmental information meets a preset condition or not;
because the time slot of daytime, the user can be according to the operating condition that self experience adjusted the air conditioner, and the operating condition of air conditioner is after taking place to change, and the operating condition of the outer machine of air conditioner can change thereupon, and at this moment, the extravagant problem of the outer machine energy of air conditioner can not appear, consequently, the technical scheme that this application discloses mainly used user falls asleep the control of outer machine of air conditioner evening, promptly, predetermine the condition for being used for the representation night user and fall asleep predetermine the condition, these predetermine the condition can be according to environmental information's difference is different, for example, when environmental information is indoor sound information, predetermine the condition can be for the intensity of indoor sound information is less than predetermineeing the decibel value in predetermineeing in the time length in succession, for example, the intensity of indoor sound information is less than 22. When the environment information is outdoor light intensity information, the preset condition may be that the intensity of the outdoor light information is less than a preset light intensity value within a preset duration, for example, the intensity of the outdoor light intensity information is less than 1lm for 30 consecutive minutes. When the environment information includes both indoor sound information and outdoor light intensity information, the preset conditions are specifically: within the present continuous preset duration, the outdoor light intensity is lower than the continuous preset light intensity value and the intensity of the indoor sound information is continuously lower than the preset decibel value, for example, the outdoor light intensity is smaller than 1lm, and the indoor sound information intensity is lower than 22 decibels for 30 minutes. In this scheme, only when the environmental information satisfies the above-mentioned preset condition, just carry out the detection of outdoor wind speed and indoor temperature detection, wherein, the purpose of the detection of indoor temperature is based on the rotational speed of outdoor axial fan of indoor temperature regulation, and this technical scheme specifically is: the detected indoor temperature is compared with the set night temperature, when the air conditioner is in a refrigerating working condition, if the indoor temperature exceeds the set night temperature, the rotating speed of the outdoor axial flow fan is controlled to be increased, if the indoor temperature is lower than the set night temperature, the rotating speed of the outdoor axial flow fan is controlled to be reduced, if the indoor temperature exceeds the set night temperature, the rotating speed of the outdoor axial flow fan is controlled to be reduced, if the indoor temperature is lower than the set night temperature, the rotating speed of the outdoor axial flow fan is controlled to be increased, and the increased or reduced step length can be set according to the requirements of users. For example, when the set night temperature is 20 °, the rotational speed of the outdoor axial flow fan is controlled to be increased by 50 rotations when the detected indoor temperature is greater than 20 °.
Step S103: detecting the ambient wind speed of the environment where the air conditioner outdoor unit is located;
in the scheme, when the environment information meets the preset condition, the ambient wind speed of the environment where the outdoor unit is located can be detected through a wind speed detector arranged on the outdoor unit of the air conditioner or other equipment; in this scheme, in order to prevent the rotating speed value of the axial flow fan of the outdoor unit of the air conditioner from being frequently adjusted when the outdoor environment wind speed is unstable, in this application, the environment wind speed may refer to an average wind speed value of the outdoor environment within a current preset time period.

When the indoor temperature is detected to be lower than 20 ℃, the outdoor axial flow fan operates in a speed reduction mode, the controller operates at a rotating speed of 725r/min, at the moment, if the ambient wind speed is higher than 8m/s, the rotating speed of the outdoor axial flow fan is controlled to be reduced by 25r/min to 700r/min, and when the ambient wind speed is detected to be lower than 8m/s, the rotating speed of the outdoor axial flow fan is controlled to be increased by 25r/min to 750 r/min. Under the heating condition, the speed change of the axial flow fan of the air conditioner is opposite.
Further, in a technical solution disclosed in another embodiment of the present application, when the rotating speed of the axial flow fan of the outdoor unit is adjusted based on the ambient wind speed, an adjustment amount of the rotating speed value may be determined according to a difference between the ambient wind speed and a preset wind speed, for example, the reducing the rotating speed value of the axial flow fan of the outdoor unit of the air conditioner may specifically include:
