a housing having a first opening and a second opening;
a heat exchanger arranged in the housing to heat exchange air drawn into the housing;
a fan arranged in the housing and rotatable around a rotation axis, the rotation axis formed to extend along a direction toward the first opening and the second opening;
a first diffuser placed at the first opening, and a second diffuser placed at the second opening, the first diffuser and the second diffuser arranged to be independently rotated, and through which heat exchanged air blown by the fan is discharged; and
a controller configured to control rotation of the first diffuser and the second diffuser,
wherein the first diffuser and the second diffuser include a plurality of vanes configured to guide the heat exchanged air blown by the fan, and the first diffuser and the second diffuser being further configured to be selectively rotatable in a same direction as a rotation direction of the fan,
the plurality of vanes are arranged to guide the heat exchanged air blown by the fan in a rotation direction of the first diffuser and the second diffuser while the first diffuser and/or the second diffuser are rotated, and
the controller is configured to control the first diffuser and the second diffuser by selecting one of:
a first state in which both the first diffuser and the second diffuser are rotated in the rotation direction of the fan,
