Abstract
A filtering system for filtering air is provided, which contains a filter and an electrode assembly downstream of the filter that contains an electrode and a counter electrode for an ionizer, between which there is a voltage for generating a corona discharge when in operation. An improved and lasting filtering effect is obtained in that the counter electrode is connected electrically to the filter in the reactivation mode. An air conditioner and a vehicle that has such a filtering system.
Claims16
A filtering system for filtering air, in particular for a vehicle, comprising
- a filter for filtering particles out of the air, through which a flow path for the air passes,
- an ionizer, which contains an electrode assembly, through which the flow path passes upstream of the filter,
- wherein the electrode assembly contains an electrode that has at least one emitter and a counter electrode, between which there is a voltage for generating a corona discharge in the air, when in operation,
- wherein the filter contains at least one electrically conductive section and at least one dielectric section, which are arranged successively along the flow path,
- with a control unit designed to operate the filtering system successively in a regular operating mode and a reactivation mode,
- wherein at least one of the conductive sections, in particular the respective conductive section, is electrically connected to the counter electrode in the reactivation mode, and disconnected therefrom in the regular operating mode.
