Abstract
An air conditioner defrosting method. In the air conditioner's heating process, after the end of every defrosting procedure, the temperature of the outdoor heat exchanger coil and the time used over the course of the defrosting procedure can be measured and recorded. The defrosting situation of the air conditioner is reflected, and an initial determination of whether there is frost accumulation is made. After the initial determination, the air conditioner continues carrying out the heating procedure, and when specific conditions are met, it carries out a third defrosting procedure. When second determination results indicate that there is frost accumulation, the frost accumulation problem is deemed to be quite severe with a risk of icing up, and it is necessary to conduct forced intervention and carry out forced defrosting steps.
