PURPOSE:To prevent dew condensation at a wall surface of a room opposing to a side surface of a main body of the unit by a method wherein air blowing ports arranged at both side surfaces of a casing of the main body of the unit is clogged by a blind cap in response to a hanging position of the main body of the unit. CONSTITUTION:In case that a blowing port 4 at the right side surface is placed near a wall surface 35 of an interior 34 and a main body 1 of the unit is hung and fixed, a blank cap 17 for the blowing port 5 at the left side surface is removed while the blank cap 17 for the blowing port 4 at the right side surface is closed, the cold air is blown at the front surface blowing port 3 and the left side blowing port 5. Also in this case, the interior air passed from the blowing grills 10 and 10 through the filter 13 into the nozzle port 7 is blown to the entire circumference by a turbo fan 6. However, since the blowing port 4 at the right side surface is closed by the blank cap 17, the blowing pressure is increased, the cold air is blown from the two blowing ports 3 and 5 at a high speed, a reaching distance of the cold air is extended and the room 34 is substantially uniformly cooled every nook and corner in it. |
