PURPOSE:To heighten a feeling of air-cooling for a worker by providing a cold air outlet port out of which cold air is blown and a human access defecting means for detecting a man present in a detection area on the main body of a spot cooler and controlling the turn of the cold air outlet port to expose the man in the detection area to the cold air. CONSTITUTION:When a first ultrasonic sensor C1 does not detect a man but a second ultrasonic sensor C2 detects him, a controller 13 identifies the presence of the man in a second detection area 22 and regulates a drive motor 7 to direct a duct 3 for cold air outlet in a direction C. As a result, even if a worker moves in the zones of a first detection area Z1, a second defection area 22 and a third defection Z3, the duct 3 for cold air outlet is turned with the movement of the worker. In such a manner, since the two ultrasonic sensors C1, C2 detect where the worker is in the three areas Z1-3 and the duct 3 for cold air outlet is arranged to turn so as to blow the cold air in the direction of the detected area, the cold air can be always directed toward the worker to heighten his feeling of air-cooling, thus making it possible to improve the working environment, even when the worker is required to work throughout all areas Z1-Z3.
