A motor vehicle includes a passenger space and a HVAC system. The HVAC system includes a heater, an air conditioner, and ducts configured to heat and/or cool air to the passenger space. The HVAC system is configured to increase humidity of air while the air is flowing through the HVAC system, and to introduce a sanitizing agent into air while the air is flowing through the HVAC system. A controller is configured to actuate the HVAC system to circulate humidified air containing the sanitizing agent through the passenger space to neutralize pathogens that may be present in the passenger space.

A sterilizer for a vehicle includes a controller, a supply water storage configured to accommodate water required for generating hypochlorous acid water (HOCL) under control of the controller, an HOCL generator configured to generate HOCL by using water accommodated in the supply water storage under the control of the controller, and a sprayer configured to inject the HOCL generated in the HOCL generator to the vehicle under the control of the controller.

A heat exchanger for an air-conditioning circuit of a vehicle. The heat exchanger enables heat exchange between fluids and has a surfaces in contact with one of the fluids. The surface is formed from aluminum and/or from aluminum alloy. The surface is coated with an alumina layer and a reinforcing layer. The reinforcing layer includes an organic substance and a mineral substance. The organic substance includes at least one polymer and the mineral substance is capable of reacting with the aluminum in order to form an anticorrosion material.

An antimicrobial, injection molded air duct for use in an air distribution system which delivers air to a passenger cabin of a vehicle or into an enclosed space within a residential structure is provided. The air duct includes a hollow, injection molded housing having an air passageway for communicating airflow therethrough. The housing includes a layer of molded material which at least partially defines the passageway and which absorbs airborne liquid droplets containing infectious, disease-causing pathogens moving with the airflow. The molded material includes antimicrobial agents disbursed throughout the layer to reduce the number of pathogens contained within droplets absorbed by the layer.

A vehicle after blow control apparatus includes a processor configured to perform an after-blow function by driving a blow motor using a high voltage battery after a vehicle is turned off; and a storage configured to store data and algorithms obtained by the processor.

Disclosed is a coating composition for preventing odor. The coating composition may include one or more types of odorless microorganisms selected from the group consisting of Caulobacter vibrioides, Bradyrhizobium diazoefficiens, Bradyrhizobium daqingense and Methylobacterium brachiatum or a culture solution thereof. Further provided is a method for preventing odor, and the method may include applying the coating composition for preventing odor. When a biofilm is formed from the microorganisms in the coating composition by coating an object on which an odor-causing microorganism can live, the inflow and the inhabitation of external microorganisms generating odor may be significantly blocked, thereby enabling odor to be effectively prevented.

A vehicle-mounted intelligent fragrance generator includes a casing and a plurality of essence boxes. The casing includes a base. Each essence box includes an outer sleeve, an inner sleeve, an essence block and a fragrance front cover, the outer sleeve has a protrusion, and the protrusion is disposed at a front end portion of an inner wall of the outer sleeve. A rear end of the inner sleeve is a closed end, a front end is an open end, and the front end of an outer wall of the inner sleeve is provided with an anti-rotation strip. The outer sleeve is fixed inside the base, the outer sleeve, the inner sleeve and the essence block are sequentially sleeved, the front end of the inner sleeve protrudes from the outer sleeve and extends out of the base, and the anti-rotation strip is clamped on the protrusion of the outer sleeve.

An air-conditioning system for a vehicle includes: a blower unit connected to an internal air flow path and an external air flow path and configured to selectively suction or discharge air; a flow path housing configured to guide air suctioned through the blower unit to the interior of the vehicle; a carbon dioxide capture module configured to selectively capture carbon dioxide contained in the air flowing into the flow path housing; and a door disposed between the flow path housing and the carbon dioxide capture module in order to selectively open or close the flow path housing.
