The invention relates to a headliner system for a motor vehicle, said headliner system comprising at least one air supply connection for connecting the headliner system to an air conditioning and ventilation system of the motor vehicle, and at least one outflow device which is fluidically connected to the at least one air supply connection, wherein at least one outflow device has at least two outflow segments, wherein one outflow segment is designed to deliver a designated air volume flow to the passenger compartment, wherein a first outflow segment surrounds a second outflow segment at least in part, and wherein at least one outflow device is designed such that it can be displaced in at least one axis of the outflow device.

A pop-up roof, for multi-purpose vehicles such as camper vans and similar, includes components for increasing the climatic comfort of the additional interior compartment of the vehicle when the rigid top of the pop-up roof is in a raised operating position. A fixed frame following the shape of the opening of the vehicle roof includes a hollow structure defining an air duct with annular development. At least one air inlet in the duct connects with an air supply channel of the air conditioning system provided in the vehicle and a plurality of air diffusion vents distributed along the air duct, sending air towards the additional internal compartment.

A roof assembly for a work vehicle includes a roof panel having a vertical peak positioned longitudinally between a forward end and a rearward end of the roof panel. In addition, the roof panel includes a forward surface extending from the vertical peak to the forward end of the roof panel, and the roof panel includes a rearward surface extending from the vertical peak to the rearward end of the roof panel. The roof panel also includes a ridge extending around a periphery of the roof panel. The ridge has a first gap positioned at the rearward end of the roof panel, a second gap positioned at the forward end of the roof panel, and a third gap positioned at a first lateral end of the roof panel. In addition, the roof panel does not include a channel extending along the roof panel.

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 vehicle vent top cover still capable of ventilation in a closed state of the top cover, which includes a top cover body, which includes a top plate; a fixed rim and side protection plates are arranged below the top plate; the fixed rim is located at the inner side of the side protection plate; the fixed rim is provided with a first ventilation groove; an air duct structural frame is fixed below the top plate; the air duct structural frame is located above the bottom walls of the side protection plates; the first ventilation groove and an upper surface of the air duct structural frame form an air inlet; one side of the air duct structural frame close to the side protection plate is provided with a second ventilation groove; and the second ventilation groove and the side wall of the side protection plate form an air outlet.

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 operator station (100) for a work vehicle comprises a roof, a roof (102), that defines an outside air inlet (201); a floor (115); several windows (106) extending between the floor (115) and the roof (102) that together define in enclosed operator compartment; an operator seat (108) disposed within the operator compartment; an air-conditioning module (112) disposed adjacent to the floor (115); a first air conduit extending between an outside air inlet (201) and the air-conditioning module (112); and a second air conduit extending between the air-conditioning module (112) and a first conditioned air outlet of the roof (102).

A device, system, and method for creating air capsules enclosing passengers in vehicles is disclosed. The device for creating air capsules enclosing passengers in vehicles includes an attachment portion. The attachment portion is removably attached to a gasper within a vehicle and receives airflow from an outlet port of the gasper. The device further includes a diffuser portion integrated with the attachment portion. The diffuser portion is configured to intake the airflow from the attachment portion. Further, the diffuser portion includes a flow control portion configured to generate at least one airflow stream from the airflow. A first airflow stream of the at least one airflow stream creates an air capsule configured to enclose a passenger in the vehicle.

A canopy downdraft fan assembly for being able to direct air flow like a curtain as selected. The canopy downdraft fan assembly includes a canopy assembly including support members adapted to be mounted upon a prime mover and including a canopy mounted upon the support members; and an air flow generating assembly in communication with the canopy assembly and including one or more fans.

An air conditioning system includes an evaporator, compressor, condenser and an expansion system in a closed system to cycle refrigerant. The components are mounted in a housing with sidewalls, bottom wall and top wall in a vertically stacked configuration with a horizontally mounted frame approximately bisecting the housing. A fan below the frame dissipates heat into or through the bottom of a vehicle and a fan above the frame circulates cool air into a passenger compartment. The air conditioning system is powered by a 12-volt direct current, which is fused (15 amperes) running off the vehicle's battery or the alternator and is operated by an electronic control circuit.
