The invention discloses an air conditioner frosting detection method and device, a storage medium and equipment. The method comprises the steps that corresponding relation between operation parametersof an air conditioner in the heating mode and frosting states of a condenser is established through self-learning capability of an artificial neural network; current operation parameters of the air conditioner are obtained; and the current frosting state corresponding to the current operation parameters is determined according to the corresponding relation. According to the scheme, the defects that in the prior art, the frosting judgment accuracy is low, the refrigerating effect is poor and user experience is poor can be overcome, and the beneficial effects that the frosting judgment accuracyis high, the refrigerating effect is good and user experience is good are achieved.
