Patent ID: 10883737

Abstract:
Provided is a ventilation control device (2) configured to control operation of one or more ventilators communicably connected thereto, the ventilation control device including: a target total exhaust volume storage unit (14) configured to store a target total exhaust volume that is a target total volume of exhaust to be discharged within a predetermined time; an exhaust capacity storage unit (13) configured to store the exhaust capacity of each of the one or more ventilators connected to the ventilation control device (2); an exhaust volume acquisition unit (17) configured to acquire an already-discharged exhaust volume discharged from each of the one or more ventilators connected to the ventilation control device (2); an integrating unit (18) configured to calculate a total already-discharged exhaust volume by adding up the already-discharged exhaust volumes of the one or more ventilators acquired by the exhaust volume acquisition unit; and an exhaust volume control unit (11) configured to, based on the total already-discharged exhaust volume calculated by the integrating unit (18), the target total exhaust volume stored in the target total exhaust volume storage unit (14), a remaining time until the elapse of the predetermined time, and the exhaust capacity of each of the one or more ventilators stored in the exhaust capacity storage unit (13), control each of the one or more ventilators connected to the ventilation control device (2) to achieve exhaust in the target total exhaust volume within the remaining time.
