Frequency control method and device based on air conditioner

The invention relates to the technical field of intelligent household appliances, in particular to a frequency control method and device based on an air conditioner. According to the method, when it is determined that the air conditioner is started, the outdoor environment temperature and the operation mode are obtained, and the initial frequency matched with the outdoor environment temperature and the operation mode is obtained; in the operation process at the initial frequency, the current first indoor environment temperature is obtained, and when it is determined that the outdoor environment temperature and the first indoor environment temperature are both in the memory data and the absolute value of the difference between the user set temperature and the first indoor environment temperature is larger than a first preset temperature, according to the user set temperature and the first indoor environment temperature, the first indoor environment temperature is obtained; determining whether to adjust the ini
