PROBLEM TO BE SOLVED: To prevent the generation of dew condensation in a louver near an air outlet on an indoor side. SOLUTION: A front panel 7 is mounted on the front of an outside box 9 where the front panel is provided with an air outlet 7a in the upper part and an air inlet 7b in the lower part. A plurality of flat board-like louvers 8 provided with a turning shaft are pivotally mounted on both ends. A rib 8a, which is projected upward substantially at right angles and whose height is approximately 1/3 of the thickness of the louvers 8, is formed on the end on the lee side while an angle corner on the opposite side of the rib 8a of the louvers 8 is chamfered. |
