The invention provides an air conditioner. The air conditioner comprises a shell body (10) and a plurality of rotating wheels (20) arranged at the bottom of the shell body (10); the air conditioner further comprises a human sensing detection part (30), a driving mechanism and a controller, wherein the human sensing detection part (30) is arranged on the outer wall of the shell body (10) and used for monitoring radiation of a user in the environment where the air conditioner is used, and outputting the data; the driving mechanism is arranged in the shell body (10) and is connected with the rotating wheels (20) in a driving mode; and the controller is electrically connected with the human sensing detection part (30) and the driving mechanism, and the controller is used for determining the moving track of the air conditioner in the environment wherein the air conditioner is used according to the data transferred by the human sensing detection part (30), and controlling the driving mechanism to drive the rotating wheels (20) to move along the moving track. According to the technical scheme, the air conditioner effectively solves the problem that in the prior art, idler wheels are arranged at the bottom of an air conditioner, the air conditioner needs to be manually moved in the moving process and consequently time waste, labor waste and inflexibility are caused during moving.
