and reducing the air output of the air outlet to be adjusted.
Referring to fig. 2, fig. 2 is a flowchart illustrating an exemplary embodiment of an air conditioner control method according to the present invention. In this embodiment, the air conditioner control method includes the steps of:

After the air conditioner is started, the frequency of a compressor required by the operation of the air conditioner is determined, wherein the determined frequency of the compressor is the frequency of the compressor when the compressor operates for heat exchange in order to meet the heat exchange requirement and the requirement on the indoor environment.
In one embodiment, the compressor frequency may be determined according to a difference between an indoor ambient temperature and an outdoor ambient temperature, for example, in a cooling mode, the indoor ambient temperature is higher than the indoor ambient temperature, and the compressor frequency needs to be increased, for example, to a maximum compressor frequency; for another example, in the heating mode, the indoor ambient temperature is greater than the outdoor ambient temperature, and the compressor frequency is maintained or decreased, for example, by 20HZ or 10 HZ. The frequency of the compressor can be determined according to the difference value between the indoor environment temperature and the set temperature, and specifically, the indoor environment temperature is obtained; determining the difference value between the indoor environment temperature and the set temperature; and determining the frequency of the compressor required by the operation of the air conditioner according to the difference value.

after determining a compressor frequency required for the operation of the air conditioner, it is determined whether the compressor frequency is less than a compressor minimum operation frequency. Each air conditioner sets a maximum operating frequency and a minimum operating frequency of the compressor in order to prevent the compressor from being damaged. The minimum compressor operating frequency may be any value from 5HZ to 10 HZ. When the frequency of the compressor is smaller than the minimum operating frequency of the compressor, the requirement cannot be met after the frequency of the compressor is adjusted to the minimum operating frequency, at the moment, the air outlet to be adjusted needs to be determined according to the indoor environment temperature and the set temperature, namely, when the frequency of the compressor is smaller than the minimum operating frequency, the requirement of the heat exchange/environment adjustment can be met by adjusting parameters except the frequency of the compressor.

And when the air output of the air outlet to be adjusted is reduced, determining other air outlets except the air outlet to be adjusted, and controlling the other air outlets to keep the current operation parameters running. Namely, other air outlets are not adjusted, the previous operation state is continuously maintained, and the heat exchange and air supply for the indoor environment are continuously performed.
In the running process of the air conditioner, if the determined compressor frequency is less than the minimum compressor running frequency, judging whether the compressor frequency runs at the minimum compressor frequency at the moment, and if not, controlling the compressor frequency of the air conditioner to be adjusted to the minimum compressor frequency to run; and determining the air outlet to be adjusted and the adjusting mode of the air outlet to be adjusted according to the indoor environment temperature and the set temperature, for example, reducing the wind shield of the fan or closing the air outlet, and determining according to the indoor environment temperature and the set temperature after adjusting the frequency of the compressor. In one embodiment, the compressor frequency set by the compressor frequency value may be adjusted for less start-stop of the compressor, maintenance of the stability of the compressor, and life of the compressor, wherein the set compressor frequency is greater than the minimum operating frequency, and the set compression frequency is greater than the minimum operating frequency by 5HZ or 10 HZ.
According to the embodiment of the application, the air conditioner is operated in the process of changing the operation frequency of the compressor, when the adjustment of the operation frequency of the compressor cannot meet the heat exchange requirement, the heat exchange quantity is adjusted by adjusting the air supply quantity of 1 or 2 air outlets in the air outlets, the situation that the compressor is continuously started and stopped to cause damage to the compressor or reduce the service life of the compressor due to continuous closing of the compressor or adjustment of the frequency of the compressor is avoided, the operation of the air conditioner is more accurately controlled, and the comfort level of the air conditioner is improved.

And after the sleeping mode is entered, the step of determining the air outlet to be adjusted according to the indoor environment temperature and the set temperature when the frequency of the compressor is less than the minimum running frequency of the compressor is executed.
