The invention discloses an air conditioner shell facilitating air conditioner air inlet area adjustment, and relates to the field of air conditioner shells. The air conditioner shell comprises a main outer shell, an air outlet groove channel is formed in one side edge of the main outer shell, a control plate groove hole is horizontally formed in one side edge of the main outer shell, a clamping hole plate is connected to one side edge of the main outer shell in a clamped mode, a temperature sensing probe is inserted into one side edge of the clamping hole plate, an air inlet channel is vertically formed in one side edge of the main outer shell, a movable sealing plate is clamped to the inner side edge of the air inlet channel, an adjusting guide plate is horizontally arranged on the inner side edge of the air inlet channel, a rear frame body is fixedly welded to the side, away from the air inlet channel, of the main outer shell, and a sealing rear plate is connected to the side, away from the air inlet channel, of the main outer shell through bolts. The device is integrated in design, simple in structure and convenient to operate, more humanization is achieved through the intelligent centralized control design, and control over the air inlet area is more accurate and efficient through the dual regulation and control structure.
