The present provides an air conditioner having the photocatalytic module installed therein and an LED disposed upstream of the photocatalytic filter on the flow path of the duct.

An HVAC system for a vehicle includes an evaporator, an ionizer, and an HVAC controller. The evaporator is configured to cool air. The ionizer is disposed in the HVAC system downstream from the evaporator and configured to ionize the cool air prior to disbursing the cool air into an environment. The HVAC controller determines a state of the air in the HVAC system. The HVAC controller determines whether a condition is present based on the state of the air in the HVAC system. When the condition is present, the HVAC controller activates the ionizer to ionize the air from the evaporator prior to the air being disbursed into the environment.

A vehicle air-conditioning system includes a cold-air circulation section in which indoor air of a vehicle is cooled via heat exchange with a refrigerant and is again supplied to a passenger compartment, a hot-air circulation section in which the indoor air is raised in temperature via heat exchange and is then again supplied to the passenger compartment, a purification circulation section in which the indoor air is introduced and purified and is then again supplied to the passenger compartment, and a refrigerant circulation section in which the refrigerant circulates to undergo heat exchange with the cold-air circulation section and the hot-air circulation section. The vehicle air-conditioning system separates an indoor air flow-path from an outdoor air flow-path to block outdoor air when performing air conditioning, and performs air conditioning of the passenger compartment using only the indoor air without entry of the outdoor air.

An air cleaner may include an electrostatic air cleaner including: an air cleaner casing; an air cleaner main body; and an air cleaner return grille cover which is coupled to the air cleaner casing, wherein the air cleaner main body may include: a filter unit which has a size greater than a predetermined particle size; a dust collector unit which secondarily filters out dust, which passes through the filter unit and has a size equal to or smaller than the predetermined particle size, by collecting the dust on an electrode plate by generating a high-tension arc; a converter unit which generates the high-tension arc on the dust collector unit; and a sensor unit which measures concentration of the dust having a size equal to or smaller than the predetermined particle size to operate the dust collector unit and the converter unit.

An apparatus for treating air includes a housing with an air inlet and an air outlet, the housing enclosing an air treatment zone and an ozone removal zone, wherein the ozone removal zone is positioned downstream of the air treatment zone with respect to a flow direction of the air being treated, an ultraviolet (UV) light source in the air treatment zone configured to generate ozone from the air, wherein the UV light from the UV light source and the ozone generated by the UV light source treat the air in the air treatment zone, catalyst in the ozone removal zone that removes at least a portion of the ozone generated by the UV light source, and an air mover positioned near the air outlet configured to draw the air through the air inlet into the air treatment zone from outside the housing.

A multilayer filter material for an interior air filter element of an air conditioning system of a vehicle may include an ion exchange layer including ion exchange particles and a plurality of further layers. The ion exchange layer may directly adjoin at least one of the plurality of further layers. The plurality of further layers may include an active layer including non-impregnated active carbon particles, and an impregnation layer including impregnated active carbon particles. The active layer may be arranged between the ion exchange layer and the impregnation layer. The ion exchange layer may be hygroscopic and may contain ions which form a toxic environment with water. The impregnation layer may include a component of active carbon particles impregnated with potassium iodide and a component of active carbon particles impregnated with potassium carbonate. The component impregnated with potassium iodide may be greater than the component impregnated with potassium carbonate.

A detection system for a vehicle comprises at least one detection device configured to detect conditions in a passenger compartment of the vehicle and a controller. The controller is in communication with the at least one detection device. The controller is configured to monitor data from the at least one detection device prior to an entry of an occupant. Based on the data from the at least one detection device, the controller is further configured to identify at least one change in the passenger compartment of the vehicle. The at least one change in the passenger compartment indicates at least one of an item left behind in the passenger compartment, damage to the vehicle, and contamination of the vehicle.

Described herein is a system and method for detecting malodor within a cabin of an autonomous vehicle, wherein initiation of a remediation system and/or dispatch of the autonomous vehicle to a service hub for mitigating the malodor is based upon sensor signals that monitor the cabin of the autonomous vehicle. The remediation system can include devices such as an HVAC system or a window, which are operated to reduce the concentration of airborne molecules in the cabin of the autonomous vehicle when the concentration of airborne molecules exceeds an air quality threshold. A dispatch protocol may be initiated to dispatch the autonomous vehicle to a service hub when the malodor is associated with certain predefined incidents or when remediation fails to reduce the concentration of airborne molecules below the air quality threshold.

An air purification device includes an adsorption block, a housing, an introduction port for indoor air, an introduction port for heated air, a return port for indoor air, and a discharge port for used regeneration air. The adsorption block adsorbs purification target substances in indoor air, and is regenerated by dispersing the adsorbed purification target substances by circulating heated air. The housing accommodates the adsorption block therein. The introduction port for indoor air and the introduction port for heated air are provided on one end side of the housing. The return port for indoor air and the discharge port for used regeneration air are provided on the other end side of the housing.
