Abstract

The invention provides an air conditioner defrosting control method and device, a storage medium and an air conditioner. The air conditioner defrosting control method comprises the steps that when the air conditioner operates in a heating mode, whether an air conditioner outer disc temperature sensor falls off or not is judged; if yes, the air conditioner is controlled to execute timing defrosting; and if not, the air conditioner is controlled to execute normal defrosting. According to the technical scheme, under the condition that cost is not increased, whether the outer disc temperature sensor falls off from a heat exchanger or not is judged according to the change condition of the outer disc temperature, if the outer disc temperature sensor does not fall off, normal defrosting is executed, once it is found that the outer disc temperature sensor falls off, simple and reliable timing defrosting is adopted, it is ensured that a frost layer of the heat exchanger is not accumulated, it is ensured that the air conditioner can still conduct defrosting normally under the condition that an outer disc temperature sensor falls off, whether frost is completely melted or not can be judged through current changes during defrosting so that defrosting can be stopped in time, and heating can be recovered in time.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner defrosting control method, device, storage medium and air conditioner. Background technique [0002] When the air conditioner is heating in winter, due to the low outdoor temperature, the outdoor heat exchanger will always produce a frost layer, which hinders the heat exchange efficiency of the outdoor heat exchanger. Therefore, it is necessary to perform defrosting action periodically to ensure the heating effect of the air conditioner. . Generally, the defrosting entry and exit conditions of the inverter air conditioner are judged by the change of the temperature of the outdoor heat exchanger coil (referred to as the temperature of the external panel). Frost needs defrosting; when defrosting is in progress, once it is detected that the difference between the outdoor temperature and the temperature of the external disk is lower than the prese...
