A vehicle roof assembly includes a roof that defines an aperture. A heating, ventilation, and air conditioning assembly is selectively disposed within the aperture. The heating, ventilation, and air conditioning assembly includes a housing defining an interior. The housing defines an intake and a vent opening. The intake is defined on a first side of the housing. A fan is disposed within the interior on a second side of the housing. The second side opposes the first side. A duct is disposed within the interior. The duct extends between the first side and the second side of the housing. The duct fluidly couples the intake with the vent opening.

A vehicle having a body including a roof supported between spaced roof rails. A plurality of roof bows extend between and are attached to the roof rails that reinforce the roof. The roof bows define an air distribution duct that includes an air inlet and at least one air vent. The air distribution duct defines a downwardly facing open channel that is closed by a headliner.

A cooling device includes a duct, a passageway, and a plurality of nozzles spaced around the duct. The duct is sized to extend around at least a portion of the dome. The passageway may extend through the duct. The plurality of nozzles may be spaced around the duct and have first openings oriented toward the passageway and second openings oriented toward the surface.

A conditioning device for a ventilation intake, the conditioning device having a frame with a mounting side, an access side, and a plurality of walls coupled between the mounting side and the access side. The mounting side defines a ventilation intake opening that is configured to receive at least a portion of the ventilation intake. The access side defines an access opening. An access panel has coupling features for removably coupling the access panel to the frame, where the access opening of the frame is accessible when the access panel is removed from the frame. The conditioning device is configured to cover the ventilation intake. At least one inlet is defined within at least one of the frame and the access panel and air enters the conditioning device through the at least one inlet.

An air conditioning unit includes a conditioning chamber, a fan with a fan air input and a fan air output, and an evaporative unit. The fan and the evaporative unit are arranged in the conditioning chamber. The fan draws in entry air to enter the air conditioning unit, then through the evaporative unit, to condition the entry air to produce conditioned air. Within the conditioning chamber, the fan is positioned and configured such that at least 30% of an area of the fan air output are positioned above an average top surface of the evaporative unit, and that air from the at least 30% of the area of the fan air output is directed towards a wall of the conditioning chamber prior to being redirected downwards and through the evaporative unit.

A vehicle having a body including a roof supported between spaced roof rails. A plurality of roof bows extend between and are attached to the roof rails that reinforce the roof. The roof bows define an air distribution duct that includes an air inlet and at least one air vent. The air distribution duct defines a downwardly facing open channel that is closed by a headliner.

A public transport land vehicle, in particular of the bus type, includes a passenger compartment intended to accommodate several people, and at least one technical compartment which can be accessed from the passenger compartment, at least one technical compartment, called upper compartment, is arranged on/in the upper wall of the passenger compartment.

A vehicle body structure includes spaced roof rails and a structural air duct. The air duct has at least two bows connecting between the roof rails and defining first and second channels. An interconnecting member is connected between the bows and defines a third channel connecting the first and second channels in fluid communication with each other. At least one of the bows defines an outlet port configured to supply air to a cabin.

A vehicle roof fan for providing air conditioning to a user of a vehicle. The vehicle roof fan may include a plurality of individually controlled fans. The apparatus includes power management features to limit the power consumption, such as a user presence detector and/or battery threshold monitoring. The plurality of fans may be associated with one or more optical sensors that each control the operation of one or more of the fans based upon the presence of a user. The air conditioning apparatus may also include heating and/or cooling components to modify the air temperature from the apparatus.

A molded ceiling material for vehicles having a substrate layer containing a porous core layer, a surface member and a ventilation control mechanism to control the ventilation volume that is vented from a cabin side of the surface member to the substrate layer. Sound generated in the vehicle cabin is absorbed by the substrate layer through the ventilation control mechanism. That is, the molded ceiling material is equipped with sound-absorption performance for sound from the cabin side of the vehicle. If the sound-absorption rate is increased, the ventilation volume to the substrate layer is increased. If the sound-absorption rate is decreased, the ventilation volume to the substrate layer is reduced. The sound-absorption rate of the molded ceiling material can be controlled regardless of the thickness of the substrate layer. Consequently, the molded ceiling materials for vehicles can be provided with sound-absorption performance corresponding to the sound-absorption characteristics of the vehicle.
