ABSTRACT:
A ventilation device, which comprises a sensor unit, a fan and control units to control on/off operation and the strength, temperature, humidity and directions of the wind or discharged air. The device can be applied to air conditioners, and ventilators. The sensor unit, monitoring the location and existence of human bodies within the ventilating area, enables the fan and the control units to be on or off while sensing the first person who comes into the area or the last person who leaves the area; and to adjust the strength and directions of the wind based on the location of the human bodies. The sensor unit, furthermore, can follow a specific human body and actuate the control units to provide needed wind based on his/her requirement. When the fan stops operating, all the openings of the ventilation device will shut so that the dust cannot get into the ventilation device.
