Control method and device for preventing air conditioner from condensation

The invention discloses a control method and device for preventing an air conditioner from condensation, and belongs to the technical field of air conditioners. The control method comprises the stepsthat the first indoor humidity value and the first outdoor humidity value of the space where the air conditioner is located are obtained; and when the first indoor humidity value is greater than the preset condensation humidity threshold value, and the first outdoor humidity value is less than the preset outdoor humidity threshold value, the air conditioner is controlled to operate a fresh air mode. By switching to the fresh air mode, air with low humidity in the outdoor environment can be introduced into the indoor environment so as to reduce the air humidity and water vapor content in the indoor environment and reduce the water vapor condensation amount when the air conditioner circulates and transports the indoor air, and use experience of users is ensured. 本发明公开了空调防凝露的控制方法及装置，属于空调技术领域。控制方法包括：获取空调所处空间的第室内湿度值和第室
