[0096] refer to figure 2 , figure 2 It is the first embodiment of the defrosting method of the air conditioner of the present invention, and the defrosting method of the air conditioner includes the following steps:
[0097] Step S10, after the air conditioner operates in heating mode for a preset period of time, collect the effective current of the external fan of the air conditioner at multiple moments;
[0098] The defrosting method of the air conditioner of the present invention is applied to the control center of the air conditioner, and is suitable for the control center of the air conditioner to control the defrosting operation of the condenser in the air conditioner according to the current change of the external fan under the heating mode, so as to avoid The condenser keeps frosting, affecting the heating effect. Specifically, the operating modes of the air conditioner include a heating mode and a cooling mode. In the heating mode, outdoor air with low temperature...

The invention discloses an air conditioner and its defrosting method and computer-readable storage medium. The defrosting method of the air conditioner includes the following steps: after the air conditioner operates in a heating mode for a preset time, collect the The effective current of the outdoor fan at multiple times; according to each effective current, judge whether the condition for defrosting the condenser in the air conditioner is reached; if the condition for defrosting the condenser in the air conditioner is reached , defrost the condenser in the air conditioner. In the present invention, the effective current at multiple times indicates that the external fan has more frosting, and when the defrosting condition is reached, the defrosting is started, and the outlet temperature of the condenser is avoided as the starting defrosting condition, which is beneficial to accurately starting the defrosting and improving the defrosting temperature. frost effect.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner, its defrosting method and a computer-readable storage medium. Background technique [0002] With the improvement of people's living standards, air conditioners have become standard electrical appliances in families. During the heating operation of the air conditioner, the outdoor low-temperature and high-humidity environment will easily cause frost to form on the condenser in the outdoor unit. As the amount of frost increases, the heating effect will be greatly reduced. Therefore, in order to ensure the heating effect of the air conditioner, it is necessary to perform a defrosting operation when the frost is formed to a certain extent. [0003] At present, the outlet temperature of the condenser is often used as the condition for starting to defrost the outdoor unit, but the outlet temperature of the condenser is affected by factors such as frequency...
