PROBLEM TO BE SOLVED: To provide an air conditioner that reduces pressure loss by reducing vortexes generated in a heat exchanger circumferential end part of a discharge port and straightening a flow field around a louver, and thereby reduces power consumption.SOLUTION: An indoor unit comprises: a housing; a motor that generates rotational driving force; a centrifugal fan attached to the motor to circumferentially discharge air sucked from a lower part; a heat exchanger 8 that surrounds a discharge direction of the centrifugal fan; and a discharge port 4 that discharges air passed through the heat exchanger. When a region between the heat exchanger 8 and the discharge port 4 out of a leeward region of the heat exchanger 8 is made to be a first region 20 and the other region is made to be a second region 21, a partition member 10 that blocks at least a part of an airflow flowing into the discharge port 4 from the second region 21 is provided.SELECTED DRAWING: Figure 8 【課題】吹出口の熱交換器周方向端部で生じる渦を抑制し、ルーバー付近の流れ場を整流することで、圧力損失を低減し、消費電力を抑制する空気調和機を提供する。【解決手段】筐体と、回転駆動力を発生させるモータと、該モータに取り付けられ、下方から吸い込んだ空気を周方向に吐き出す遠心ファンと、該遠心ファンの吹出し方向を囲う熱交換器８と、該熱交換器を通過した空気を吹き出す吹出口４と、を備え、前記熱交換器８の風下領域のうち、前記熱交換器８と前記吹出口４の間の領域を第一領域２０とし、それ以外の領域を第二領域２１としたとき、該第二領域２１から前記吹出口４に流入する気流の少なくとも一部を遮る仕切部材１０を設けた。【選択図】図８
