When the wall air conditioner is operated, indoor air is introduced into the indoor unit through the suction grills 5 and 5 'by driving an indoor fan (centrifugal fan) 11, and the indoor air introduced as described above is indoors. The heat is exchanged with the refrigerant flowing in the heat exchanger while the temperature is lowered through the evaporation of the refrigerant.

The indoor air, ie, cold air, whose temperature is reduced in this way, flows to the discharge grill 13 installed at the bottom of the front panel 3 and the indoor heat exchanger 9 by the indoor fan, and flows to the discharge grill 13. The cold air is discharged by the louver 16 and the vane 15 to be discharged into the room.

In the case of the wall-mounted air conditioner configured as described above, since the suction grille 5 is exposed while the front panel 3 protrudes rounded forward, that is, the structure of the air conditioner currently being pursued by the user's demand, that is, the front panel.
