Description

Method and device for dehumidifying air conditioner, air conditioner and storage medium Technical Field The application relates to the technical field of intelligent household appliances, in particular to a method and a device for dehumidifying an air conditioner, the air conditioner and a storage medium. Background The dehumidification (Air conditioning dehumidification) of the air conditioner means that the whole air conditioner is in a dehumidification operation state, and at the moment, a fan of the indoor unit is operated slowly, so that the air conditioner is convenient for condensing moisture in air into liquid to achieve the dehumidification effect. The existing air conditioner dehumidification method is to determine the temperature according to the outdoor environment temperature and then correct according to the difference between the indoor environment temperature and the set temperature. When the difference is small, the target evaporation temperature can be increased, and the frequency of the compressor during refrigeration can be reduced.
