S100, continuous collecting the first temperature value T1 and second temperature value T2.
Environment temperature sensor is for detecting room temperature in air conditioner, and coil temperature sensor is for detecting outdoor unit disk
The temperature of pipe.After air conditioner runs a period of time, it is in metastable state, the temperature of continuous collecting the first temperature value T1 and second
Angle value T2, obtains the collected value of multiple groups different time points, which is the environment of environment temperature sensor acquisition
Temperature, second temperature value T2 are the temperature of the outdoor unit coil pipe of coil temperature sensor acquisition.
If S200, the first temperature value T1 and second temperature value T2 meet the first preset condition, the air-conditioning is controlled
Device operation defrosting operation.
The the first temperature value T1 and second temperature value T2 of the acquisition of multiple groups different time points are obtained by step S100, so
After judge whether the first temperature value T1 and second temperature value T2 meet the first preset condition, the first temperature value T1 and second
Temperature value T2 meets the first preset condition, including following four scene:
Scene 1: after air conditioner runs the first preset time, in first time period, the first temperature value T1 and the
The difference of two temperature value T2, which is consistently greater than, is equal to the first preset threshold, and the second temperature value T2 is less than or equal to the second default threshold
Value.Any one time point of the starting point of the first time period after the first preset time.
Scene 2: after air conditioner runs the second preset time, in second time period, second temperature value T2 is small always
In equal to third predetermined threshold value.Any one time point of the starting point of the second time period after the second preset time.And
When the air conditioner is in different operating statuses, the length of the second time period is also different.
Scene 3: after air conditioner runs third preset time, the first temperature value T1 and second temperature value T2 meet mathematics
Model T1-T2 > T1*x+y, and the first temperature value T1 is greater than the 4th preset threshold, the second temperature value T2 is default less than the 5th
Threshold value, wherein x, y are constant.The trend condition judgement of temperature is carried out by establishing the mathematical model, and combines verification experimental verification knot
Fruit is finally reached the purpose precisely to defrost.
Scene 4: after air conditioner runs the 4th preset time, within the third period, which is less than etc.
In the 6th preset threshold.Any one time point of the starting point of the third period after the 4th preset time.
Collected first temperature value T1 and second temperature value T2 are brought into respectively in scene 1- scene 4, judgement is
It is no at least to meet a scene, as long as meeting any of them, control air conditioner operation defrosting operation.
Optionally, with reference to Fig. 3, which further includes step S300:
If S300, the second temperature value T2 meet the second preset condition, air conditioner defrosting out of service is controlled
Operation.
