Abstract: A discharge unit includes a discharge electrode, a counter electrode opposed to the discharge electrode, and an insulation member having a surface. The surface is continuous from the discharge electrode to the counter electrode. A wall portion is provided on one side with respect to a discharge region formed by the discharge electrode. The wall portion is configured to suppress a contaminant from adhering to the surface of the insulation member.

Abstract: An air purification device includes a controller configured to perform a normal discharge operation in which a discharger generates streamer discharge to purify air, and an emergency discharge operation in which, in order to remove substances, which are components contained in air, adhering to electrodes of the discharger due to the normal discharge operation, a higher voltage than that in the normal discharge operation is applied to the electrodes to cause the discharger to generate spark discharge. The controller adjusts an application voltage such that a current value between the electrodes is maintained constant, and the upper limit V of the application voltage is set at a value greater than an inter-electrode distance of d×1.2 (V≧d×1.2).

Abstract: A ventilation system includes an inside air passage having inflow and outflow ends communicating with an indoor space to be ventilated, at least one permeable film unit including a permeable film, and an air supply passage having an inflow end communicating with an outdoor space and an outflow end connected to a downstream side of the permeable film in the inside air passage. The permeable film allows a target gas to pass and allows the target gas that has passed through the permeable film to be discharged into outdoor air. The target gas contains at least one of carbon dioxide and a volatile organic compound in indoor air that flows in the inside air passage. Alternatively or in addition, the ventilation system can include an outside air passage and a discharge passage in place of or in addition to the inside air passage and the air supply passage, respectively.
