<p><P>PROBLEM TO BE SOLVED: To provide a ventilation system that can suppress costs associated with ventilation while making a ventilation amount in each interior space suitable with simple constitution by adjusting the amount of outside air to be introduced according to the number of persons in each interior space, and also adjusting the amount of outside air sent to a duct according to an increase or a decrease in the outside air. <P>SOLUTION: If the number of persons in an interior space 70 estimated from a detection result of a human sensor 30 is sufficiently large when the outside air is blown in blow-off openings 71, 72 of the interior space 70 through a duct 10, constant wind volume adjustments 11, 12 which are upstream from the blowoff openings are controlled to a passage state of a sufficient amount of outside air, but when less than several persons are present, on the other hand, the passage of the outside air by the constant wind volume adjustment portions 11, 12 is suppressed to carry out ventilation corresponding to the number of persons in the space, thereby reducing the air-conditioning load of the interior space while preventing a defect in ventilation. Further, a blower 20 is controlled according to variation in duct pressure accompanying operation switching of the constant wind volume adjustment portions 11, 12 to suppress energy consumption for ventilation with simple control configurations. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
