The method comprises the steps of detecting and recording the temperature of an outer disc of the air conditioner in real time based on a temperature sensor, judging whether the current air outlet angle of the air conditioner is larger than a first preset angle or not, if the current air outlet angle of the air conditioner is smaller than the first preset angle, the current air guide door angle is larger, and further calculating the temperature variation of the temperature of the outer disc within a second preset time so as to judge the operation load of the air conditioner. The first preset angle may be a value of the air guide door angle in a smaller angle range, for example, the value range of the first preset angle may be 0 to 90 degrees. The temperature variation may be a difference between the current outer disc temperature and the outer disc temperature before or after the second preset time period.
In one specific embodiment, the outer disc temperature is within a second predetermined time periodThe temperature variation is the difference between the current outer disc temperature and the outer disc temperature before the second preset time, the value range of the second preset time is 10-30S, the preferred value is 20S, the current time is 0S, the difference between the current outer disc temperature and the outer disc temperature before 20S is calculated and recorded as the temperature variation T 0 s-first 20s . Through calculating the difference of current outer dish temperature and the outer dish temperature before the second preset duration, can calculate the temperature variation who obtains the outer dish temperature fast, and then can judge air conditioner operating load's the situation of change, promoted air conditioner control's reliability.
