Abstract:
A method of disinfecting one or more surfaces and an apparatus for use in the method. The method includes a securing step arranged for creating an isolation of the surfaces to be disinfected, a disinfection step for emitting UV radiation for the generation of ozone and/or for the sterilization of air from one or more ultra violet (UV) light sources, and adding the generated ozone to the isolation, and a termination step arranged for terminating the generation of ozone and terminating the securing step.
Abstract:
An air purification device with ozone and find dust cleaning, and optionally heating, cooling and dehumidifying function, is formed for installation in a room of a building. The air purification device comprises a first air channel to supply fresh air and a second air channel to discharge extract air. The two air channels lead through a heat exchanger. The air purification device further comprises a third air channel which opens into the first air channel after the heat exchanger. An electric filter/ozone generator is arranged in the first air channel after the first inlet and in the third air channel after the third inlet. A first fan is arranged in the first air channel after the electric filter/ozone generator and a second fan is arranged before the active carbon filter. A control unit is programmed to operate in at least one first operating mode the second fan with a higher suction power than the first fan.

Abstract:
When the electrically driven fan (14) of a vacuum cleaner is driven, air containing dust is drawn into the cleaner main body (1) through a hose (7) connected to a hose socket (8) and is exhausted into the outside of the cleaner main body (1) through an exhaust port (1b) via first and second suction passageways (10, 13). Disposed outside the first suction passageway (10) is an ion generator (23), it being arranged that plus and minus ions generated in the ion generator (23) are fed to the air stream flowing in the first suction passageway (10). Since the plus and minus ions kill floating germs in the air stream, the exhaust can be purified.
Abstract:
An ion generating apparatus prevents a determination that no ions are being generated even when ions are being generated. The ion generating apparatus includes: an ion generator that generates ions; an ion detector that detects generated ions; an air blower that blows the generated ions to an outside through an air supply passage; and a control section that controls driving of the ion generator and the air blower. The control section stops the air blower at a start of operation, performs ion detection using the ion detector, and determines whether ions are being generated. When the control section determines that no ions are being generated, the control section continuously performs a determination of ion generation. When the control section determines that no ions are being generated in all determinations, it is finally determined that no ions are being generated.
Abstract:
An air conditioner comprises a housing, a main fan, a heat exchanger, and a discharge generator. The housing is formed with an inlet, an outlet, a main airflow path. The inlet is provided for introducing outside air. The main airflow path extends from the inlet to the outlet. The main fan is disposed in the housing. The main fan is provided for generating a forced flow of the air through the main airflow path. The heat exchanger is disposed in the housing to heat and/or cool the air which flows through the main airflow path. The discharge generator has a casing, an emitter electrode, and an electrical insulator. The casing is formed with an intake, an outtake, and a second airflow path. The intake is provided for taking in the air into the casing. The outtake is communicated with the intake via the second airflow path within the casing in order to pass airflow through the casing. The electrical insulator is made of an electrical insulating material. The emitter electrode and the electrical insulator are disposed within the casing so as to form a discharge space. The emitter electrode is configured to apply high voltage to the discharge space. The emitter electrode has a circumferential surface. The circumferential surface is spaced from an inside surface of the casing by a clearance. The inside surface of the casing is opposed to the circumferential surface of the emitter electrode. The second airflow path is shaped to flow the airflow both through the clearance and the discharge space.
Abstract:
A method and device for cleaning air. The air to be cleaned is directed as a continuous flow in succession through a) a first zone wherein the air is treated with ozone and possibly also water, ammonia or other aerosol growth promoters; b) a second zone wherein the air is subjected to ultraviolet light; c) a third zone wherein the air is maintained for a sufficient time to allow aerosol growth; d) a fourth zone where particles in the air are given an electrical charge; e) a fifth zone wherein the air is passed through an electrostatic filter; and f) a sixth zone wherein the air flows over a catalyst to break down residual ozone. The air in confined spaces including indoor rooms, public vehicles with limited access to fresh air is subjected to a low energy consuming universal broad-spectrum removal of the various types of indoor air pollution including toxic gases, organic compounds, microorganisms and liquid and solid particles being hazardous to health and detrimental to quality of life.
Abstract:
The present invention generally relates to a system for the decontamination of air wherein airborne particles and other pollutants are either neutralized and/or destroyed by ozone. The system generally comprises an access chamber for receiving the air to be decontaminated, an ozone generator generally fluidly connected to the access chamber, and at least one treatment chamber, in communication with the access chamber, in which ozone, present in high concentration, can effectively neutralize and/or destroy the airborne particles and/or the other pollutants contained in the air. The air decontamination system is typically used in cooperation with the ventilation system of a building.
