The invention relates to the technical field of
air conditioning, and discloses a method for condensation-preventing control. The method comprises the steps: the indoor temperature and the indoor
humidity are obtained; and in the case that the indoor
humidity is within the set range, the
operation time of a fan is adjusted according to the indoor
humidity and the indoor temperature to prevent an uneven temperature field from being formed at an air outlet. According to the method for condensation-preventing control of the embodiment, in the case that the indoor humidity is within the set range,namely the humidity range where an air conditioner is prone to generating condensation, in the range, the
operation time of the fan is adjusted by synthesizing the indoor humidity and the indoor temperature, the situation that condensation is generated in the case that the stable operation state of the fan is maintained for a long time and blown out, and consequently the user experience is influenced is avoided, by adjusting the
operation time of the fan, the uneven temperature field is preventing from being formed at the air outlet, and the risk of generating condensation is reduced. The invention further discloses a device for condensation-preventing control, and the air conditioner.
