Abstract:
An ozone generating apparatus comprises at least one ozone generating unit which includes: two electrodes mutually (2, 31) which are opposed to generate a discharge in response to high voltage applied therebetween; at least one dielectric (4) interposed between the electrodes to provide insulation between the electrodes; and a gas supply mechanism to supply an oxygen-containing gas between the electrodes so as to generate ozone by the discharge. In this unit a spacer (61) is inserted into a discharge space (5) causing the discharge to ensure a predetermined distance or more between the electrodes of the ozone generating unit, and the spacer forms a non-discharge portion where no discharge occurs.
Abstract:
An ozonizer, wherein plate-shaped electric discharge cells are prevented from being deformed, and, even when ozone gas of high concentration and high pressure is produced, an outstanding ozone generation efficiency can be secured. The main body (10) of the ozonizer formed by stacking a plurality of electric discharge cells (11) is housed in a pressure vessel (20). Pressurized gas having a pressure equal to the pressure of material gas supplied to the electric discharge cells (11) is supplied to the pressure vessel (20). The difference between the interior and the exterior of an electric discharge cell (11) is eliminated, so that the deformation of an electric discharge cell (11) is prevented. Dry gas is used as the pressurized gas, whereby the insulation failure due to condensation can be avoided.
Abstract:
The invention relates to a ventilation system (10, 50) comprising a line system (12, 52) which is designed to guide an air stream (14, 54) and to provide the air stream (14, 54) during normal operation (N) via an outlet (16, 56) of the line system (12, 52) for supplying a space (18, 58), wherein the ventilation system (10, 50) comprises a generating unit (34, 66, 100, 170) which is designed to produce reactive oxygen species during a cleaning operation (R) and to feed the same to the air stream (14, 54) conducted in the line system (12, 52). The invention further relates to the use of such a ventilation system (10, 50) for ventilating or air-conditioning a room of a building or an interior of a closed device, a method for operating such a ventilation system (10, 50) and a generating unit (34, 66, 100, 170) for such a ventilation system (10, 50).
Abstract:
Improvements in the supply of high-frequency electrical power to ozone-producing cells can be accomplished using the systems and techniques described herein. Application of a DC-DC converter operating at a switching frequency substantially greater than a load frequency, supports generation of a high- voltage AC for powering such cells, while allowing for reductions in component size and reductions in a quality factor of a load tuning circuit. Controllable power inverters used in obtaining one or more of the switching and load frequencies can be controlled using feedback techniques to provide stable, high-quality power to ozone-producing cells under variations in one or more of externally supplied power and load conditions. An inrush protection circuit can also be provided to selectively introduce a current-limiting resistance until an input DC bus has been sufficiently initialized as determined by measurements obtained from the DC bus. The current limiting resistance can be a positive-temperature coefficient thermistor.
