Air disinfection apparatus for use in air conditioning systems

An air disinfection apparatus based on hydrogen peroxide for use with an air conditioning system configured to create an airflow, the air disinfection apparatus comprising:

• a hollow housing for conveying said airflow therethrough between an air inlet and an opposite air outlet in an airflow direction;
• a screen forming a non-ionizing electrode extending along a screen longitudinal extension axis, said non-ionizing electrode being mounted in the hollow housing between the air inlet and the opposite air outlet so that a screen surface is parallel to the airflow direction;
• a wire forming an ionizing electrode, said wire being suspended in said hollow housing between the air inlet and the opposite air outlet and having a wire axis aligned with the screen longitudinal extension axis so as to face said screen surface;
• terminals electrically connected to the wire and the screen for coupling thereto high and low voltage outputs of a high voltage generator of sufficient voltage to create a corona discharge zone across the airflow between the wire and the screen;
• wherein the screen includes an ion receiver screen portion positioned downstream of the corona discharge zone relative to the airflow direction, said ion receiver screen portion causing ions produced in the corona discharge zone to be attracted thereon, the ion receiver screen portion extending parallel to the airflow direction so as to prevent release of ions outside of the air disinfection apparatus.
