For example, in the heating working state of the air conditioner, when the outdoor environment temperature is 20 ℃, the difference value between the outdoor environment temperature and the second preset temperature of 16 ℃ is less than 6, so that the relay of the outer unit fan is set to be on for 1 second, off for 1 second, on for 1 second, and off for 1 second, so that the outer unit fan performs a corresponding intermittent operation mode.
