Problems solved by technology

Neither of the above two methods can fundamentally solve the problem that the operating frequency of the compressor of the air conditioner cannot be effectively adjusted due to the failure of the outdoor temperature sensor, resulting in the shutdown or low-efficiency operation of the entire air conditioner, which is not conducive to user experience.

Abstract

The invention provides a control method and control device of an air conditioner and the air conditioner. The control method of the air conditioner comprises the steps that whether a temperature detecting device of the air conditioner works normally or not is judged; when it is judged that the temperature detecting device does not work normally, the current running parameter of the air conditioner is detected, and a database prestored in the air conditioner is searched for target outdoor temperature corresponding to the current running parameter according to the current running parameter; the real-time running frequency of a compressor of the air conditioner is controlled according to the target outdoor temperature. According to the technical scheme, the situation that due to the fact that the temperature detecting device breaks down, and the outdoor temperature at this moment cannot be acquired, the real-time running frequency of the compressor cannot be effectively adjusted, and the air conditioner cannot work normally can be avoided, and meanwhile the situation that due to the fact that the running frequency of the compressor exceeds the highest compressor running frequency corresponding to the estimated outdoor temperature value, the service life of the air conditioner is shortened is avoided.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner control method, an air conditioner control device and an air conditioner. Background technique [0002] At present, in the air-conditioning system, the outdoor temperature is a relatively important reference quantity, which is often used to set the upper limit of the operating frequency of the air-conditioning compressor. When the outdoor temperature sensor of the air conditioner fails, the operating frequency of the compressor cannot be effectively adjusted due to the inability to obtain the outdoor temperature of the air conditioner at this time, and the compressor may run beyond the upper limit of the operating frequency. The service life of the air conditioner is reduced. In this case, two methods are generally adopted: one method is to shut down the air conditioner and send an alarm to indicate that the air conditioner is faulty, so that t...
