The invention provides an air conditioner, a control method and device of the air conditioner and a readable storage medium. The air conditioner comprises at least one outdoor fan. The control method comprises the steps that the frequency of a compressor, the rotating speed of the outdoor fan and high pressure are obtained; in the refrigeration mode or the dehumidification mode, when the frequency of a compressor reaches a first threshold value, the rotating speed of an outdoor fan reaches a second threshold value, and the duration reaches a first time threshold value, the air conditioner is controlled to enter a target control mode; wherein in the target control mode, the rotation direction and the rotation speed of the outdoor fan are controlled according to the high pressure. According to the technical scheme, when the refrigeration mode cannot be operated at the low environment temperature, frequent starting and stopping of the outdoor fan are avoided.

The invention discloses an anti-condensation control method and device for an air conditioner and a multi-connected air conditioner, and relates to the technical field of air conditioners. The method comprises the steps that in the operation process of an oil return mode, the temperature of a coil pipe of a shutdown indoor unit is periodically detected; if the coil pipe temperature is smaller than the preset temperature threshold value, it is determined that the shutdown indoor unit has the condensation risk, and the opening degree of an expansion valve of the shutdown indoor unit is controlled to be increased by the first opening degree to run for the first preset duration; and the gas separation liquid level is detected, if the gas separation liquid level is larger than or equal to the preset alarm liquid level, the opening degree of an expansion valve of the shut-down indoor unit is subjected to opening degree reduction control, and an inner fan of the shut-down indoor unit is controlled ...
