By the suction effect of the blower 330, the air flow passes through the casing of the air conditioner 1 and enters the inside of the air conditioner 1. The air flow passes through the heat exchanger 10 under the suction effect of the fan 330 and enters the two air inlet cavities, and at this time, the air flow is heated or cooled by the heat exchanger 10. The air flow entering the air inlet cavity enters the fan 330 through the air inlets of the two fans 330 under the action force of the fan 330 and is guided out of the shell of the air conditioner 1 through the fan 330, so that heating or refrigerating is completed. When the heating effect does not meet the user requirement, the electric auxiliary heating device 20 is used for carrying out auxiliary heating on the air flow, so that the heating effect is improved. Wherein, can separate two air inlet cavities that form through guide plate 320 and advance air to two fans 330 respectively, can avoid the mutual influence between two fans 330, and then guarantee that the air inlet of two fans 330 is stable even, can guarantee that the intake of two fans 330 is roughly the same, further realize the even stable purpose of air-out of air conditioner 1.
