Abstract

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: when the air conditioner is in the defrosting state, acquiring the Inlet temperature and outlet temperature; judging whether the inlet temperature and the outlet temperature reach the preset condition for ending the defrosting of the condenser in the air conditioner, wherein the preset condition is based on the outside of the outdoor unit of the air conditioner The external ambient temperature of the environment is generated; if the preset condition is reached, the defrosting operation of the condenser in the air conditioner is ended. Because the preset condition is correlated with the external environment temperature, the present invention fully considers the heat radiation phenomenon of the outdoor heat exchanger during defrosting by judging whether the inlet temperature and the outlet temperature reach the preset condition as the condition for judging the end of defrosting The impact on defrosting is beneficial to accurately judge the time to end defrosting and improve the effect of defrosting.

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 defrost the condenser first, and then perform heating after the defrosting is completed. [0003] At present, the outlet temperature of the condenser often reaches the set value as the condition for ending the defrosting of the outdoor unit. Different, the outlet temperature at the end of defr...
