Variable-frequency air conditioner control method and air conditioner

The invention discloses a variable-frequency air conditioner control method and an air conditioner. The variable-frequency air conditioner control method comprises the steps: entering a user setting mode in response to a user operation instruction; acquiring a running frequency, which is set by a user, of an air conditioner compressor; controlling the air conditioner compressor to run at the set running frequency. Furthermore, the user can also set different running time periods of a variable-frequency air conditioner compressor and the running time lengths and the running frequencies of all the time periods; in each running time period set by the user, the air conditioner compressor is controlled to run at the set running time length and the running frequency; moreover, a difference value between the set temperature ts and the indoor temperature t1 can be judged in any time period after the air conditioner compressor runs according to the preset time length or a default time length, and frequency rising and frequency falling are determined according to the difference value or the current frequency is kept until the period is ended; the comfortableness of the air conditioner is guaranteed, and energy conservation of the air conditioner can be realized; more different demands of the user are met.
