The embodiment of the invention provides an air conditioner, a control method thereof, an operation control device and a storage medium. The air conditioner comprises the operation control device anda temperature detection device, wherein the temperature detection device is electrically connected with the operation control device and is configured to be used for detecting a working condition temperature parameter, feeding back the detected working condition temperature parameter to the operation control device, and triggering the operation control device to determine to switch into a breezeless mode from a current cooling or heating mode according to the acquired working condition temperature parameter or maintain the current cooling or heating mode. According to the air conditioner provided by the scheme, the temperature detection device is arranged for detecting the working condition temperature parameter, an operating mode of the air conditioner is timely adjusted according to thechange of the working condition temperature parameter, and meanwhile, the mode switching of the air conditioner is realized by control through the operation control device according to the detected working condition temperature parameter, so that compared with manual control of a user, automatic control is realized, the convenience in control is realized, and the accuracy in mode switching controlis high.
