A roof structure for an agricultural vehicle includes an upper roof assembly and a lower roof assembly connectable to the upper roof assembly. The lower roof assembly or the upper roof assembly includes a ventilation opening for guiding air-conditioned air and a circulation opening for supplying recirculated air. An air-guiding element is arranged between the lower and upper roof assembly. The air-guiding element is further disposed at the circulation opening and the ventilation opening such that a region sealed in relation to an external environment is formed.

A roof structure for an agricultural vehicle includes an upper roof assembly, a lower roof assembly, and an air-conditioning chamber formed in the lower roof assembly. The upper roof assembly is connectable to the lower roof assembly to surround the air-conditioning chamber. An inlet chamber and an outlet chamber for air-conditioned air are provided such that the inlet chamber and the outlet chamber between the lower roof assembly and the upper roof assembly include chambers separated from each other. The structure also includes a circulation opening for supplying recirculated air arranged at the inlet chamber and an air-guiding element arranged in the inlet chamber, at the circulation opening, and at the air-conditioning chamber. A region is sealed in relation to an external environment.

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.

Systems and methods to distribute airflow in an internal space of a transport unit are described. The airflow distribution system may include an airflow distributor forming an airflow passage with a roof of the transport unit. The airflow distribution system may be also configured to allow airflow to discharge from a gap between the airflow distributor and the roof. The gap may be provided by at least one spacer between the airflow distributor and the roof. A back end of the airflow distribution system may be configured to provide a back pressure to the airflow passage while allowing the airflow to discharge. In operation, a front end of the airflow distribution system may be configured to receive airflow. The airflow can be distributed along the airflow passage and be discharged from the gap and the back end.

A roof system for a vehicle having a roof opening in a roof part thereof comprises a transparent panel in the roof opening, and a ventilation system for moving air into and/or out of the vehicle interior. The ventilation system includes an air guiding channel guiding air between the vehicle interior and the environment through at least one ventilation opening. The air guiding channel is fitted centrally below the transparent panel and extends in longitudinal direction of the vehicle, substantially completely along the panel and communicates with the interior at least along a substantial length of the panel through holes.

A vehicle ventilation system is provided to exhaust hot air from the interior of a motor vehicle to the ambient environment. The vehicle ventilation system includes a roof vent having an elongated housing pivotally disposed on a roof of a motor vehicle, wherein the roof vent is movable between an open and a closed configuration. A fan assembly is disposed within the opening and serves to exhaust hot air from the interior of the vehicle. Further, one or more front seat vents are provided that allow cool air to flow into the vehicle as hot air escapes through the roof vent. The vehicle ventilation system further includes a control circuit having a temperature sensor configured to actuate the roof panel and front seat vents when a predetermined temperature is reached.

A vehicle overhead console is provided herein. The vehicle overhead console includes a housing operably coupled with a bracket. The bracket is configured to further couple to a headliner. An air-monitoring device is disposed on a first side of the housing. The air-monitoring device draws air from a first side of the housing and exhausts the air on an opposing side of the housing.

A covering structure for use with a roof opening in a vehicle to ventilate an interior cabin thereof comprises a base supported on an exterior side of a vehicle roof, an upstanding peripheral wall enclosing a space above the roof and registered with the roof opening, one or more openings in the wall to communicate the space with an ambient environment and a securement device for anchoring to the vehicle, which is configured to extend from the space enclosed by the peripheral wall and through the roof opening to the interior cabin so as to attach inside the vehicle. The covering structure can be operated as an air scoop by closing, using movable covers, the majority of the wall openings except for those facing the wind, so that the peripheral wall acts to duct the admitted air into the cabin through the roof opening.

A roof assembly for an autonomous work vehicle includes a roof panel having an outer surface. The roof assembly also includes a lighting assembly having a light-transmissive panel and a light source. The light-transmissive panel is coupled to the roof panel, the light-transmissive panel has an outer surface, the outer surface of the roof panel completely surrounds the outer surface of the light-transmissive panel, and the light source is configured to emit light through the light-transmissive panel. The light source is configured to receive a signal from a controller indicative of a selected status indication of a group of status indications and to emit the light based on the selected status indication, the group of status indications correspond to a respective group of operating states of the autonomous work vehicle, and the selected status indication corresponds to a current operating state of the group of operating states.

A downdraft fan assembly mountable on a vehicle roll bar, which may be used for providing a flow of ambient air over the vehicle operator, and a canopy carried by the fan assembly, which may be used for providing solar and precipitation protection for the operator. The downdraft fan may draw air through a roof cap with a rear-facing outlet, or may draw air through a series of vents disposed around the canopy of the assembly, or through some combination of the two, such as may be desired. In some variations, multiple openings may be provided in the roof, if desired.
