An air ionization system is provided for creating an ionized airflow within a transit vehicle. The air ionization system includes a block having electronic control circuitry therein, air ionizing electrodes, and wiring electrically coupling the air ionizing electrodes to the electronic control circuitry. The air ionizing electrodes are mounted remote to the block in the transit vehicle and are mounted within an air distribution unit of the transit vehicle.

A vehicular air conditioning system includes an air-conditioning case having a plurality of passages divided by a partition wall, and an ion generator configured to emit anions and cations into the passages. The ion generator includes a plurality of discharge electrodes installed to extend into the passages of the air-conditioning case and configured to emit anions and cations into the passages. The partition wall of the air-conditioning case includes a communication portion configured to bring the passages into communication with each other so that the discharge electrodes installed in the passages face each other in the same space.

The present inventive concept relates to an air treatment device adapted to treat air in a confined space. The air treatment device comprises a device body having a central axis, the device body comprising a supporting structure being substantially transverse to the central axis and a side section being substantially parallel to the central axis. The air treatment device further comprises an air treatment section arranged in the device, an ionizing arrangement, a fan arrangement, and a filter extending in a first direction being parallel to the central axis, wherein the filter comprises an upper end and a lower end in the first direction, wherein the ionizing arrangement and the fan arrangement are arranged between the upper and lower end.

An ionized air delivery system, such as a vehicle ionized air delivery system, includes an outlet body that is situated within a duct of a heating, ventilation, and air conditioning (HVAC) system. The outlet body delivers ions to air flow in the duct of the HVAC system. The outlet body has an outer surface that is generally spherical at a region of the outer surface that confronts the air flow in the duct. Further, the outlet body has an outlet passage with a primary axis that is directed away from an exit of the duct of the HVAC system. Air flow in the duct passes across an exit opening of the outlet body and draws ions out of the outlet passage to mix with the air flow in the duct of the HVAC system.

A device includes a housing including an inlet and an outlet, the inlet being configured to intake an infectious agents contaminated air, and the outlet being configured to output a sterilized air. The device also includes a superheating heat exchanger configured to increase a temperature of the infectious agents contaminated air by superheating the contaminated air, the infectious agents contaminated air becoming the sterilized air after being superheated. The device further includes a cooling heat exchanger configured to cool down the sterilized air and direct the sterilized air to the outlet of the housing.

A vehicle system includes: an olfaction sensor comprising: a blower configured to draw air through an inlet; a filter configured to filter particulate from the air; and a volatile organic compounds (VOC) sensor disposed downstream of the filter and configured to measure an amount of VOCs in air after the air flows through the filter; and a control module configured to selectively take one or more remedial actions based on the amount of VOCs.

An ion generating device can include a housing having an opening, an anode and a cathode disposed within the housing and having a space between them in fluid communication with the opening, a power source having a negative terminal and a positive terminal with a first connection between the negative terminal and the anode and a second connection between the positive terminal and the cathode, and an air mover disposed to direct an air flow through the space and out of the opening.

The present invention relates to an electrification apparatus for electric dust collection and an air conditioner for a vehicle comprising the same. According to the teachings of the present invention, there is provided an electrification apparatus for electric dust collection including: a frame, conductive microfiber and conductive. The frame includes a main body frame in which the conductive plate is installed and an installation frame in which a fixing groove in which the conductive microfiber is installed is formed. At this time, the electrification apparatus for electric dust collection further includes a rubber which is coupled with the conductive microfiber and is inserted into the fixing groove.

A built-in apparatus and method for treating air including a housing with an air inlet and an air outlet. An air mover positioned near the air outlet is configured to draw the air through the air inlet. The housing encloses an air treatment zone, such as including an oxidizing zone, and an ozone removal zone positioned downstream of the air treatment zone and oxidizing zone. The air treatment zone includes UV light and/or ozone that partially oxidizes the chemical contaminants in the air treatment zone. A catalyst in the oxidizing zone oxidizes elements within the air treatment zone. The ozone removal zone includes a second, different catalyst material. A UV bulb that may or may not generate ozone is positioned within or downstream of the first and/or second catalyst materials to assist catalyst oxidation and/or self-clean the apparatus.
