Indoor unit and air-conditioning apparatus

An indoor unit comprising:

• at least one air outlet having formed therein an inner air-passage wall and an outer air-passage wall located at outside of the inner air-passage wall, the outer air-passage wall being between an installation surface of the indoor unit and the inner air-passage wall;
• and
• at least one air flow direction louver disposed in the air outlet, the air flow direction louver being rotatable about a rotation axis and configured to deflect air blown from the air outlet by an angular position thereof in rotation, wherein
• while the indoor unit is in an operating state, the outer air-passage wall and the air flow direction louver define therebetween an outer air passage through which the blown air passes, and the inner air-passage wall and the air flow direction louver define therebetween an inner air passage through which the blown air passes, and
• the air flow direction louver is rotatable to an upward position, being the angular position, at which
• the outer air passage between the outer air-passage wall and the air flow direction louver and
• the inner air passage between the inner air-passage wall and the air flow direction louver
• are narrowed, and the outer air-passage has a higher air flow resistance than the inner air passage.
