Working method and working device for air-conditioner and air-conditioner

The invention discloses a working method and a working device for an air-conditioner and the air-conditioner. The method comprises the steps that a control mode and the working condition of the air-conditioner are determined, wherein the working condition comprises refrigeration and/or heating; the air-conditioner works according to the control mode and initial operating parameters corresponding to the working condition; after continuously working for preset time, the air-conditioner adjusts the operating parameters according to the law corresponding to the control mode, and works according to the operating parameters after being adjusted. By means of the working method, the problems that a set temperature control mode is single without change and the true requirements of users on various occasions can not be well met in the correlation technology, the intelligence performance of the air-conditioner is improved, and the user experience is improved.
