  As shown in FIG. 10, an illuminance sensor 38 that detects ambient brightness is provided, and a control unit 35 that controls driving conditions by detecting the brightness of a room is provided. When the surroundings become darker than a certain value ( For example, only 10 to 15 Lx) is configured to increase the air volume of the supply air by increasing the rotation speed of the supply air impeller 9 and the supply air driving motor 10. As a result, it is possible to save energy by ventilating a large air volume only when there is a person. The illuminance sensor only needs to be able to detect brightness, and includes, for example, a quantum infrared sensor such as a photodiode.

  The heat exchange function can be easily provided using the heat exchange element, and by installing the heat exchange element on the indoor side of the ventilator, it can be used for applications such as a heat exchange ventilator with a space-saving and energy-saving air conditioning function. Is also applicable.
