An air conditioning indoor unit comprising: a casing attached to a wall surface facing an air conditioning target space, the casing having a blow-out port; a fan disposed in the casing and sends air to the blow-out port; a first horizontal blade configured to adjust an up-and-down wind direction of blow-out air flowing from the blow-out port to the air conditioning target space; a first drive unit configured to drive the first horizontal blade; a second horizontal blade disposed closer to the wall surface than the first horizontal blade and configured to adjust the up-and-down wind direction of the blow-out air; a second drive unit configured drive the second horizontal blade; and a control device (100, 200) configured to control the fan and the first and second drive units (73, 74), wherein the air conditioning indoor unit is capable of performing an operation in a first airflow control mode in which a distance between the first horizontal blade and the second horizontal blade is larger on a downstream side of a flow of the blow-out air than on an upstream side of the flow of the blow-out air, the blow-out air flows obliquely downward on an opposite side of the wall surface, a part of the blow-out air flows along a lower wing surface of the first horizontal blade, and another part of the blow-out air flows along an upper wing surface (5 1c) of the second horizontal blade, and the lower wing surface of the first horizontal blade has a protruding curved surface, characterized in that: the upper wing surface (5 1c) of the second horizontal blade includes a curved surface that is curved and protrudes in a thickness direction of the second horizontal blade. a casing attached to a wall surface facing an air conditioning target space, the casing having a blow-out port; a fan disposed in the casing and sends air to the blow-out port; a first horizontal blade configured to adjust an up-and-down wind direction of blow-out air flowing from the blow-out port to the air conditioning target space; a first drive unit configured to drive the first horizontal blade; a second horizontal blade disposed closer to the wall surface than the first horizontal blade and configured to adjust the up-and-down wind direction of the blow-out air; a second drive unit configured drive the second horizontal blade; and a control device (100, 200) configured to control the fan and the first and second drive units (73, 74), wherein the air conditioning indoor unit is capable of performing an operation in a first airflow control mode in which a distance between the first horizontal blade and the second horizontal blade is larger on a downstream side of a flow of the blow-out air than on an upstream side of the flow of the blow-out air, the blow-out air flows obliquely downward on an opposite side of the wall surface, a part of the blow-out air flows along a lower wing surface of the first horizontal blade, and another part of the blow-out air flows along an upper wing surface (5 1c) of the second horizontal blade, and the lower wing surface of the first horizontal blade has a protruding curved surface, characterized in that: the upper wing surface (5 1c) of the second horizontal blade includes a curved surface that is curved and protrudes in a thickness direction of the second horizontal blade.
