AI Technical Summary

Technical Problem

Conventional air filtration systems in vehicles, particularly aircraft, struggle to effectively remove small particles like viruses and bacteria while managing high energy consumption and electromagnetic interference from electrostatic filters.

Method used

An air cleaning system with an electrostatic filter module surrounded by an electromagnetic pulse (EMP) shielding device, using honeycomb panels made of electrically conductive or non-conductive materials, combined with mechanical and physicochemical filters to enhance filtration efficiency and safety.

Benefits of technology

The system effectively removes viruses, bacteria, and other pollutants while preventing electromagnetic interference, ensuring a safe and clean cabin environment by integrating EMP shielding and multiple filtration stages.

Abstract

Vehicle interior air purification system with at least one electrostatic precipitator module (30) through which air to be purified can flow, which has at least one high-voltage electrode (30') and at least one control electrode (30"), between which an electric field can be generated by applying a high voltage provided by a power supply module (32), wherein the electrostatic precipitator module (30) is surrounded by a shielding device (31) and forms an electrostatic precipitator unit (3) with the shielding device; wherein, in the flow direction (V) of the air to be cleaned, at least one shielding module (34, 36) through which the air can flow is provided upstream and / or downstream of the electrostatic precipitator module (30), which shielding module has a plurality of air passage elements, each of which defines an air passage channel (38, 39) surrounded by a channel wall (38', 39'), wherein the shielding module (34, 36) through which the air can flow has at least one honeycomb panel (35, 37), the individual honeycombs (35', 37') of which are open at both ends and each form one of the air passage channels (38, 39), and wherein the respective channel wall (38', 39') is electrically conductive or has an electrically conductive surface, characterized by that the honeycomb panel (35, 37) consists of electrically non-conductive material as a carrier material, the surface of which is provided at least in regions with an electrically and / or magnetically conductive material.
