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.

An air conditioning system for an open motorized vehicle can include a cab assembly defining an interior volume, the cab assembly includes an enclosed frame configured to be attached to an open vehicle, and an air conditioning unit positioned at least partially within the cab assembly, the air conditioning unit being configured to deliver conditioned air to the interior volume of the cab assembly.

A utility vehicle capable of off-road travelling includes a cabin, a floor panel including a floor tunnel, an air blower and a duct. The duct includes a first end part that is connected to the air blower, a second end part including an opening part open to a rear half portion of the cabin, and an extending part that extends between the first and second end parts. The extending part includes a first part extending in the front-rear direction. The whole duct is arranged above the floor tunnel.

The invention provides a ventilation member attached to a wall member having a wall opening. The ventilation member includes: an outer surface member attached to an outer surface of the wall member to cover the wall opening; and an inner surface member attached to an inner surface of the wall member to cover the wall opening and coupled to the outer surface member. The outer surface member and the inner surface member are configured as identical members and each have an opening and at least one fin provided in the opening.

A motion driven cooling system configured to operate with one or more transportation devices. The motion driven cooling system includes a moving object in communication with a transportation device. The moving object transfers power from the movement of the transportation device and operates a water pump system and a fan system. The cooling system includes a water housing configured to retain water. The water pump communicates with the moving object and is configured to move water from the water housing to a second location where the water passes through one or more elements and returns to the water housing. The fan communicates with the moving object and is configured to move air across the water at the second location so as to lower the temperature of the air. An outlet port directs the flow of air as desired.

Implementations of vehicle seating systems may include a movable chair including a metal frame having a seat portion and a back portion. The seat portion may have a first end and a second end and the back portion may have a first bar, a second bar, and a lock bar coupled between the first bar and the second bar. A latch pin may be configured to receive a first end of the lock bar coupled to the first bar of the seat portion when the movable chair is in a fully upright portion. The back portion may be configured to fold down and the seat portion may be configured to rotate upwardly on the seat hinge. The movable chair may be configured to lock into place in a fully upright position when the vehicle is in operation through a latching mechanism, the latch pin, and the lock bar.

A blower fan is driven, and conditioning air flows down through an evaporator and then is supplied into a vehicle compartment. An idling-stop condition in a roof-open state is set to make an idling stop to be relatively easily attained, compared to a roof-closed state, so that a fuel economy can be improved. When an outside-air temperature is a specified temperature or higher or a solar-radiation intensity is a specified degree or greater at an engine's automatic stop, the blower fan is driven, so that the conditioning air is supplied toward a passenger in a manner of an electric fan. The evaporator through which the conditioning air flows down is sufficiently cool at the timing right after the automatic stop of the engine. Accordingly, it is preferable to configure such that the sufficiently-cooled conditioning air is supplied for a properly-long period of time.

A paver work machine comprises of a hopper, a screed, a thermal manage system with a heat pump, and a controller. The hopper receives and distributes paving material, and the screed levels the paving material on the ground surface. The thermal management system includes a thermal energy circuit for circulating a medium through an evaporator, a compressor, a condenser, and an expansion device. The compressor receives the medium from the evaporator and is operable to compress and circulate the medium through the thermal energy circuit. The evaporator receives the medium from the expansion device and is operable to transfer heat to the medium. The condenser is operable to desorb heat form the medium and adapted to transfer heat desorbed from the medium to one or more the hopper or the screed. A controller controls heat transfer between the condenser and one or more of the screed and the hopper.

An off-road vehicle includes: a dash panel separating a cabin space and a front space; a dashboard located behind the dash panel and facing an occupant seat; a front panel located in front of the dash panel; and an air conditioner located in an accommodating space defined between the dash panel and the dashboard. An outside air suction port of the air conditioner is located in an intake space that is covered with the dash panel from a rear side and is covered with the front panel from a front side.
