A headliner trim for a motor vehicle includes a main body, at least one air channel formed in the main body for conducting an air flow through the main body, and at least one air outlet opening formed in the main body, through which air outlet opening the air flow conducted in the air channel can flow into the interior of the motor vehicle. The main body is formed from a particle foam, such as expanded polypropylene (EPP) or expanded polyethylene (EPE).

An air delivery system for a vehicle comprises an HVAC system and an air duct fluidly coupled with the HVAC system. The air delivery system comprises a rail extending parallel to the air duct. The system comprises a module having a rail rider slidably coupled with the rail. The module defines an air inlet in selective fluid communication with the air duct. The module defines an air chamber in fluid communication with the air inlet. The module comprises an air register fluidly coupled with the air chamber. The air delivery system comprises a sensor that senses at least one of a distance between the module and the HVAC system; and an air flow therebetween. The air delivery system comprises a controller that controls the air flow based upon at least one of the measured distance between the module and the HVAC system and the air flow therebetween.

A work vehicle is provided with a body, a driver section and an air conditioner, and the air conditioner is supported by the body and located on a side of the body.

A mobile power supply housed within a wheeled trailer which can be towed to various locations, particularly remote locations, for providing electrical power as needed for operating equipment or for charging of batteries or other electrical supply devices at such remote locations. The apparatus includes a unique trailer design including venting means for preventing the accumulation of hydrogen normally associated with high power battery operation, particularly charging thereof and therewith, by monitoring hydrogen at all times within the trailer interior and selectively passively and actively venting the interior environment when hydrogen levels are high or whenever necessary. A unique roof design is included for gathering hydrogen near the upper portion of the interior roof construction adjacent to a venting outlet to facilitate expelling thereof.

An air-conditioning device for a vehicle includes a first evaporator and a second evaporator provided on a vehicle roof in a longitudinal direction of the vehicle. A refrigerant distributor is provided at a portion at which a refrigerant is supplied to the first evaporator and the second evaporator. The refrigerant distributor is operated to introduce the refrigerant selectively into the first evaporator and the second evaporator.

A riding vehicle is provided with a downdraft fan assembly mounted on a vehicle roll bar for providing a flow of ambient air over the vehicle operator and a canopy carried by the fan assembly and providing solar and precipitation protection for the operator.

A roof (102) for work vehicle comprises a molded roof portion (200) formed by rotational molding, the molded roof portion (200) having a first surface (202) that is generally planar and faces upward, and a second surface (300) molded integral with the first surface (202), wherein the second surface (300) faces downward and has a plurality of integrally molded troughs (308, 310) that extend upward into the second surface (300).

A roof air vent device includes: a roof provided to cover an upper portion of a vehicle; a duct housing provided in the roof extending in a length direction or width direction of the vehicle to draw air into the duct housing; a guide member provided inside the duct housing in the extending direction of the duct housing to distribute the air drawn into the duct housing; and a rotating nozzle including a discharge unit provided to the duct housing to discharge the air drawn into the duct housing into a vehicle cabin and to change directions of air discharge by rotation of the discharge unit.

Example embodiments relate to an air cooling system for an electronic spinning assembly. An example embodiment includes a plurality of vanes coupled to a static base. A vane cover is rotatably coupled to the static base. The vane cover includes at least one air inlet, at least one air duct extending from the vane cover, and at least one choke point disposed in the cover. The at least one choke point is configured to increase a pressure of the airflow.

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.
