Abstract: A disadvantage such as loss of life to a bearing of an indoor fan motor may occur when the number of rotations of the indoor fan falls below a predetermined number of rotations. An indoor unit includes a fan, a casing, a first horizontal flap, a second horizontal flap, and an indoor controller. The casing accommodates the fan, and has a blow-out port through which air provided by the fan is blown out. The indoor controller performs opening and closing operations to bring the first and second horizontal flaps into a first state in decreasing an airflow volume to be blown out through the blow-out port. In the first state, the first horizontal flap is in a position to open a first portion of the blow-out port while the second horizontal flap is in or substantially in a position to close a second portion of the blow-out port.

Abstract: This indoor unit of an air conditioner includes an indoor unit main body having an inlet and an outlet; a heat exchanger; and a cross-flow fan configured to blow out air, which has undergone heat exchange by the heat exchanger. The cross-flow fan has a blow-out flow path that is configured such that a cross-sectional area gradually increases downward, with the blow-out flow path guiding blown-out air to the outlet. When a distance in the lower wall from an intersection, where a tangent inscribing a tongue of the cross-flow fan orthogonally intersects the lower wall, to a lower end of the indoor unit main body is referred to as distance L, a ratio (L/D) of the distance L to outer diameter D of an impeller of the cross-flow fan is less than 0.05. At least part of the blow-out flow path is formed to project out of the outlet at least when air conditioning operation is performed.
