Reference numeral 5 is a height adjusting means for fixing the movable unit to the main body, 6 is an operation part of the air conditioner main body, 7 is an indoor wall surface, 8 is a floor surface, and 9 is a ceiling surface.

2 and 3 are longitudinal sectional views showing the inside of the air conditioner indoor unit body 1 and the movable unit. 2 and 3, 1 is an air conditioner indoor unit main body, 2 is a movable unit, 3 is an upper air flow port provided in the movable unit 2, and 4 is an air conditioner main body 1.
It is a lower air circulation port provided in the lower part of. Reference numeral 5 is a height adjusting means for fixing the movable unit to the main body, 6 is an operation portion of the air conditioner main body, 7 is an indoor wall surface, 8 is a floor surface, and 9 is a ceiling surface. 10 is an air conditioner indoor unit body 1
, A refrigerant pipe to the heat exchanger 10, 12 a first blower arranged inside the movable unit 2, and 13 an inside air conditioner indoor unit main body 1. It is the 2nd blower arranged.

When installing the air conditioner indoor unit, when installing the air conditioner, the movable unit 2 is moved upward after the air conditioner body 1 is installed at a predetermined position. The movable unit 2 is fixed to the air conditioner body 1 by the height adjusting means while the upper surface of the movable unit 2 is in contact with the ceiling surface. The upper air circulation port 3 provided in the movable unit 2 is located very close to the ceiling surface 9, and the lower air circulation port 4 provided in the lower part of the air conditioner indoor unit body 1 is very close to the indoor floor surface 8. To position.

When performing cooling, an air flow designated as CA is set. Heat exchanger 1 via refrigerant pipe 11
