The invention discloses an air conditioner device. The air conditioner device is used for transmitting energy through windows or accessories in an equipment room or other rooms. The air conditioner device comprises a first heat exchanger (1), a compressor (2), a second heat exchanger (3) and an expansion valve which are connected in series in sequence through a pipeline. The first heat exchanger (1) is installed in the room, and a door (4) or a door frame (5) or a window frame is internally provided with a heat transfer channel. An air inlet (6) and an air outlet (7) connected with the two ends of the heat transfer channel are formed in the outer side of the door (4) or the door frame (5) or the window frame, and a draught fan (8) used for sucking air from the air inlet (6) and exhausting the air from the air outlet (7) after the air passes through the heat transfer channel is arranged on the door (4) or the door frame (5) or the window frame. The second heat exchanger (3) is installed in the heat transfer channel. The air conditioner device can be applied to some rooms where existing air conditioners cannot be installed, and therefore the environment of the rooms is improved.
