Similarly, when the temperature of the person is too high, the air duct type air conditioner indoor unit in the room where the person is located is controlled to operate in the second air outlet mode, the volute air outlet 31 is controlled to rotate to the corresponding position of the side air inlet 101, and the heat exchange amount of the heat exchanger 10 is controlled, so that the air duct type air conditioner indoor unit blows cold air from the side direction of the side air inlet 101. Therefore, the user can obtain good experience no matter in the refrigeration working condition or the heating working condition. Furthermore, the air duct type air conditioner indoor unit of the application can play a certain guiding role to the air flow under different working conditions by arranging the rotatable baffle 8, and no matter the air duct type air conditioner indoor unit is a refrigerating working condition or a heating working condition, a complete air duct curve can be formed by rotating the baffle 8 by a certain angle, so that air flow turbulence and turbulence in the air duct are avoided, air supply quantity is increased, and air duct noise is reduced.
