An indoor unit of air conditioner, comprising an air outlet duct (16) of a crossflow impeller and an air outlet duct wall (15) of the crossflow impeller. An air drafting opening (13) is provided on the air outlet duct wall (15) of the crossflow impeller. With the upper extremity (12) and the lower extremity (14) of the air drafting opening (13) being in a projection plane perpendicular to the axis line of the crossflow impeller of the indoor unit and on which an air outlet (17) of the indoor unit is located at the lower left side, the clockwise angle (131) between the line running from the upper extremity to the lower extremity and the positive direction segment of a tangent to the air outlet duct wall with the upper extremity serving as the point of tangency is greater than or equal to 0° and less than or equal to 220°. The indoor unit of the air conditioner provides a large air outlet volume and outputs an airflow that exchanges heat with indoor air to form a mixed airflow that is cool but not cold. |
