It is understood that the first cooling high rotation speed, the second heating high rotation speed, the first cooling high rotation speed, and the second cooling high rotation speed are all greater than the rotation speed of the centrifugal fan 1. The third preset value is greater than the first preset value, and the second preset value is greater than the fourth preset value. The specific values of the parameters are set according to actual needs, which is not limited in this embodiment.
In the practical application process, the optimization can be further performed according to the practical requirements, for example, when the indoor temperature is not less than the third preset value and less than the fifth preset value during the air-conditioning refrigeration, the controller is used for controlling the refrigeration high rotating speed to be the third refrigeration high rotating speed; when the indoor temperature is not less than the fifth preset value, the controller is used for controlling the refrigeration high rotating speed to be a fourth refrigeration high rotating speed; and the fourth refrigeration high rotating speed is greater than the third refrigeration high rotating speed, and the fifth preset value is greater than the third preset value. When the air conditioner heats, when the indoor temperature is not more than the fourth preset value and is more than the sixth preset value, the controller is used for controlling the heating high rotating speed to be a third heating high rotating speed; when the indoor temperature is not more than the sixth preset value, the controller is used for controlling the heating high rotating speed to be a fourth heating high rotating speed; and the fourth heating high rotating speed is greater than the third heating high rotating speed, and the fourth preset value is greater than the sixth preset value. Similar to this optimization, all fall within the scope of protection of the present invention.
