A vehicle air conditioner includes an external air introduction port, an internal air introduction port, an internal/external air-switching door, an air blower, a plurality of types of blowing ports, an internal/external air changeover switch, and a control device. The plurality of types of blowing ports blow conditioning air from a place that corresponds to a selected blowing mode. Even in a case where the internal/external air changeover switch is operated such that the external air introduction port is opened, when a blowing mode that opens a predetermined blowing port having a large total opening area among the blowing ports is selected and when an output of the air blower is equal to or more than a predetermined value, the control device controls the internal/external air-switching door such that the internal air introduction port is partially opened.

An air-guiding element for arrangement in an interior compartment, which is at least partially enclosed by windows, of a motor vehicle is provided. The air-guiding element is designed to generate a turbulent flow downstream of the air-guiding element when an air flow impinges on the air-guiding element. A motor vehicle having said air-guiding element is also described.

A vehicle dashboard includes a trim panel defining an airflow opening. At least one register duct defines a register opening. The at least one register duct is disposed adjacent to the trim panel and the register opening aligns with the airflow opening. At least one demister duct defines a demister opening. The at least one demister duct is disposed adjacent to the trim panel and the demister opening aligns with the airflow opening. A first air deflector slidably engaged with the at least one register duct. A second air deflector slidably engaged with the at least one register duct.

A vehicle and method are provided for monitoring and changing quality of air in a passenger compartment of a vehicle so that the air quality remains above a predeterminable threshold value. The vehicle has an air quality sensing device and an air quality changing device. The method includes sensing the quality of the air in the passenger compartment and in the surroundings of the vehicle with the air quality sensing device; and in the event that the quality of the air in the passenger compartment of the vehicle drops below the predeterminable threshold value, changing the quality of the air in the passenger compartment of the vehicle with the air quality changing device so that the quality of the air in the passenger compartment rises above the predeterminable threshold value.

Various disclosed embodiments include illustrative door assemblies, vehicles, and methods of assembling door assemblies. In an illustrative embodiment, a seat includes a base section, a back section, a first section of duct, and one or more vents couplable to the first section of duct. The first section of duct is configured to receive air from an air supply source and the first section of duct is disposed at least partially within the base section. The one or more vents are disposed at an aft surface of a section chosen from the base section and the back section.

The present embodiments relate to an air distribution apparatus for distributing conditioned airflow from a roof mounted air conditioner to the inside of a vehicle, which includes an inlet port adapted to receive the conditioned airflow from the roof mounted air conditioner. An outlet port, which is disposed adjacent to each longitudinal end of the apparatus, delivers conditioned airflow to the vehicle. An internal supply duct is adapted to evenly split the conditioned airflow to the outlet ports.

A vehicle air conditioner, including a first duct having a first ventilation opening that is disposed on first side in a width direction of a seat provided in a vehicle, a second duct having a second ventilation opening that is disposed on second side in the width direction of the seat, the second side being opposite side of the first side, and a third duct having a third ventilation opening that is disposed in front of the seat.

A vehicle cabin airflow forming device includes an airflow forming unit. The airflow forming unit is configured to form airflows circulating around seating space of a seat and form, as part of the airflows, an ascending airflow on one lateral side of the seating space, and a descending airflow on the other lateral side of the seating space. The seat is provided inside a vehicle cabin, and the airflows circulate around the seating space as viewed from a front side of the seat.

The present disclosure provides an air conditioning device for a vehicle. The air conditioning device includes an air conditioning unit disposed in at least one of front or rear of the vehicle. The air conditioning device further includes a duct unit blowing air of the air conditioning unit into an interior and extending inside of at least one of a front pillar or a rear pillar. The air conditioning device further includes a vent unit communicating with the duct unit through a connecting duct and selectively opening and closing a discharge path of at least one of a main path, a first path, or a second path so as to discharge the blown air to a side of a roof frame.
