Kind Code:
A1
Abstract:
This ventilation system comprises a supply air passage, an exhaust air passage, a supply air blower, an exhaust air blower, a supply air volume adjustment unit, an exhaust air volume adjustment unit, an air quality detection unit, and a control unit. The supply air passage connects an intake port for drawing in external air to a first air supply port provided in a first area and a second air supply port provided in a second area. The exhaust air passage connects a first exhaust port provided in the first area and a second exhaust port provided in the second area, to a discharge port for discharging the air in the space to the outside. The supply air volume adjustment unit is capable of changing the distribution between the first supply air volume from the first air supply port and the second supply air volume from the second air supply port. The exhaust air volume adjustment unit is capable of changing the distribution between the first exhaust air volume at the first exhaust port and the second exhaust air volume at the second exhaust port. The air quality detection unit independently detects the quality of air in the first area and the second area. The control unit controls the supply air blower, the exhaust air blower, the supply air volume adjustment unit, and the exhaust air volume adjustment unit on the basis of the detection results of the air quality detection unit.
