• Air conditioning components that can be placed between the fan (20R, 20L) and the back of the casing (10) and between the two fans (20R, 20L) include a switch box (61), a drain pump, and a refrigerant pipe (62a). ), Drain piping (62b), etc., and any air conditioning components may be appropriately selected and arranged. Further, when the fans (20R, 20L) are arranged in the casing (10) of the indoor unit (1) having the front outlet (43) and the side outlet (44) as in the above embodiment. In addition, the corners of the casing (10) tend to be dead spaces regardless of the number of fans (20R, 20L) used. Thus, the casing (10) can be further reduced in size.
