PROBLEM TO BE SOLVED: To provide a control device of a continuous ventilator which continuously performs ventilation in low air volume, while operating in such low air volume that does not give a sense of coldness to a person at the time when the person enters a ventilation area, and operating in large air volume for a predetermined time at the time when the presence of the person is out, so as to promote the improvement in an environment. SOLUTION: A human detecting means 2 that detects the presence of a person is provided in an area to be ventilated of a continuous ventilator 1 that is constantly operated to ventilate in predetermined air volume. A control means 4 is provided to continue the continuous ventilating operation during the time when the detection of a person continues after the person is detected, and it is provided with a large air volume operating means 3 that operates in large air volume when the detection of the person is out. Thereby, when a person enters the ventilation area, it is operated in such low air volume that does not give a sense of coldness to the person. When the presence of the person is out, it is operated in large air volume for a predetermined time, so as to promote the improvement of an environment. |
