Because the fan does not relate to the refrigerant and the rotating speed of the fan is not higher than that of the compressor, the operating environment temperature of the fan is higher than that of the compressor under the general condition, and the fan can still operate under the general condition when the compressor cannot operate. The temperature sensor is positioned in an air duct of the fan, is used for monitoring the outdoor environment temperature, and is arranged at a position which is not influenced by the operation of the fan under special conditions.

When the first temperature value is less than or equal to the first preset temperature, the fan and the compressor are controlled to operate according to the operation parameters corresponding to the starting instruction.
According to the control method of the air conditioner, when the start-up instruction of the air conditioner is detected, the first temperature value currently detected by the temperature sensor is obtained, whether the obtained first temperature value is larger than a first preset temperature is determined, then the first temperature value is larger than the first preset temperature, the operation parameter corresponding to the first temperature value is obtained, the fan and the compressor are controlled based on the obtained operation parameter, the fan and the compressor can be controlled according to the corresponding operation parameter when the detection result of the temperature sensor is high, the problem that the air conditioner cannot be started up and operated when the ambient temperature is high due to solar radiation is avoided, the reliable operation of the air conditioner is guaranteed, and the user experience is improved.

In the control method of the air conditioner provided by this embodiment, it is determined whether the first temperature value is greater than a second preset temperature by determining whether the first temperature value is greater than the second preset temperature, wherein the second preset temperature is greater than the first preset temperature, then when the first temperature value is less than or equal to the second preset temperature, the fan is controlled to start, the second temperature value detected by the temperature sensor is obtained in real time, then when the second temperature value is less than or equal to the first preset temperature and the duration of the fan operation is less than or equal to the first preset duration, the compressor is controlled to start, and when the first temperature value is higher and is caused by solar radiation, the compressor is controlled to start and operate after the detection result of the temperature sensor is reduced by the fan, so as to avoid that the air conditioner cannot start and operate when the ambient temperature is higher due to solar radiation, the reliable operation of the air conditioner is ensured, and the user experience is further improved.

In this embodiment, when the duration of the stop operation of the fan reaches a second preset duration, the fan is controlled to start, and even if the fan starts to operate again, the fan is controlled to operate at a rotating speed corresponding to the start-up instruction of the air conditioner, so that the detection result of the temperature sensor is reduced as much as possible, and a third temperature value detected by the temperature sensor is obtained in real time.
It should be noted that, in order to increase the reduction rate of the temperature value detected by the temperature sensor, when the fan is started, the fan may operate according to a preset rotation speed, where the rotation speed is greater than the rotation speed corresponding to the start-up instruction, or the rotation speed may also be the maximum rotation speed of the fan.
