The present disclosure relates to an air vent structure. The air vent structure at least includes a tubular housing through which an air-conditioned air flows, and an annular finisher in an air flow-out end of the housing. The air vent structure further includes an air restrictor that restricts the inflow of the air-conditioned air into a clearance between the air flow-out end of the housing and the finisher.

Provided is a silencer including: an expansion chamber having a cuboid shape; a first pipe for being coupled to a noise source, the first pipe being coupled to an approximate center of a first surface of the expansion chamber; and a second pipe coupled to an approximate center of a second surface of the expansion chamber adjacent to the first surface. The expansion chamber has an internal space and a partition in the internal space, the partition is disposed upright on a third surface of the expansion chamber opposed to the second surface of the expansion chamber to extend from the third surface toward the second surface, and the second pipe has a central axis substantially included in the partition.

A connection apparatus, a manufacturing method of the connection apparatus, and a thermal management component are provided. The connection apparatus includes two or more plate bodies; the adjacent plate bodies are fixed and connected in a sealed manner; the connection apparatus is provided with a channel; at least one channel part is arranged in at least one of the adjacent plate bodies; the adjacent plate bodies define a channel at the channel part. One of the side walls of at least one plate body is provided with a mounting portion and/or a connecting portion along the axial direction or radial direction of the connection apparatus; the mounting portion is internally provided with a mounting hole for communication with the channel; the the connecting portion is provided with a connecting hole.

A valve in receiver (VIR) for a climate control system includes a receiver drier shell having an outer surface and an inner surface defining an interior portion having an opening. A drier housing is disposed in the receiver drier shell and a molded desiccant is disposed internal to the drier housing. The molded desiccant is configured to form a restrictive fluid flow passage along an interior surface of the drier housing.

An air conditioning system having an air conditioner housing and a condensation drain device, the air conditioner housing having a condensation outlet, the condensation drain device being connectable to the condensation outlet, an essentially rotationally symmetrical connecting element having an undercut being provided on the air conditioner housing, and a compatible receiving element being provided on the condensation drain device, so that the condensation drain device may be detachably fastened to the air conditioner housing for transport purposes.

A device for reducing the noise of motor vehicle air conditioning units, having at least one air flow limiting element which projects laterally on an outer circumference of an axial air inlet opening vertically out of an air inlet opening plane and has a surface which limits or blocks a flow path next to the axial air inlet opening, at least two plate-shaped air guiding elements, which are arranged on an inside of a recirculation air flap in mutually spaced parallel planes at right angles to an axis of rotation of the recirculation air flap, and an air flow guiding element which is arranged on a fan tongue and extends radially from the fan tongue at a distance from a fan wheel into a spiral flow channel.

The invention proposes a method for recovering a liquid collected on an interior or exterior surface (1, 19) of a motor vehicle bodywork (17) or glazing (2) element, characterized in that it consists in analysing a quantity of the collected liquid stream using a device (30) for measuring or estimating a parameter indicative of a state of pollution of the collected liquid, such as its turbidity, in comparing a measured value of the turbidity against a threshold value and, when the measured value is below the threshold value, in directing the collected liquid stream towards a recovery unit (9) or, when the measured value is above the threshold value, in discharging the collected liquid stream, for example in the form of waste.

A hood article and a method of use for a seat conditioning assembly. The hood article including an air-impermeable housing with an internal hollow chamber and at least a first aperture adapted and a second aperture to connect an air mover to a collar device of an air distribution system assembly. The hood article used for fluidly connecting the air mover to the air distribution system assembly.

The present invention discloses an air quality monitoring device that can measure the hazardous gas contents, including benzene, formaldehyde and VOCs, and other air quality measurements inside train cars in real time. The air quality monitoring device can be installed inside a train car, either in the middle of the car, or at the end, or other locations. Each air quality device is equipped with a unique ID (e.g., MAC address, IP address, and RFID), which can be associated with a car or location inside the train. When hazardous gas level in a train car exceeds the safety level, this car or location can be identified and an air quality control unit injects or sprays photocatalyst material to the air to improve the air quality.
