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.

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.

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.

A work vehicle includes a cabin to cover an operator's seat on a traveling body. A cabin frame that constitutes a framework of the cabin includes a pair of left and right front pillars, a pair of left and right rear pillars, a front beam, a rear beam, and side beams. The front beam couples upper end portions of the front pillars to each other. The rear beam couples upper end portions of the rear pillars to each other. Each of the side beams couples to each other upper end portions of each of the front pillars and each of the rear pillars that stand at a front and rear. The rear beam is formed to have a U-shaped cross-section by presswork of a metal plate material.

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 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 fans.

An in-vehicle air conditioning device includes a plurality of air conditioning openings provided for each of a plurality of seats of the vehicle at at least one of an upper part and a lower part of the vehicle corresponding to each seat; a plurality of airflow generators that are provided for each of the air conditioning openings and generate an airflow discharged from the air conditioning openings while controlling a temperature and an amount of the airflow; and a controller that individually controls the plurality of airflow generators, wherein at least some of the plurality of airflow generators include an air volume distribution adjustor adjusts planar distribution of a volume of air that passes through the air volume distribution adjustor, and wherein the controller control an amount of the planar distribution of the volume of air adjusted by the air volume distribution adjustor.

A vehicle headliner is equipped with an air vent system, which includes a vent base member having a surface which faces a roof panel and on which a roof duct is mounted. The vent base member has multiple vent holes so that a fluid is sprayed toward a vehicle interior. A breathable surface layer is mounted on a surface of the vent base member which is exposed to the vehicle interior. The vent base member may include a polyurethane foam, fiberglass mats, which are attached to both surfaces of the polyurethane foam by glue, respectively, and non-woven fabrics, which are attached through hot melt films to surfaces of the fiberglass mats, respectively, which are opposite to the surfaces attached to the polyurethane foam.

A vent shade assembly for a recreational vehicle ceiling vent comprises a vent shade outer frame having an inner flange, a vent shade inner frame having an inner flange, and a pair of side walls disposed between the inner flange of each of the outer and inner frame to form a slot. A movable pleated shade element disposed within the slot is operable between a closed position and a plurality of positions there between. A first and a second shade string is disposed at least partially alongside and parallel to a first and second of the pair of side walls, respectively, and proximate a first and a second side edge of the movable pleated shade element, respectively. A portion of the inner flange of the vent shade outer frame supports the first and second side edge of the movable pleated shade element.

According to the invention, there is provided a positive pressure vent (10) for a vehicle (12). The vent (10) includes an inlet chamber (14) having an air intake port (16) facing into an air stream generated by motion of the vehicle (12) so as to collect air and form a positive pressure inside the inlet chamber (14). There is further provided a filter (18) adapted to filter air from the inlet chamber (14) of particulate matter. A filtered air path (25) is further provided for allowing filtered air from the filter (18) to travel to the interior of the vehicle (12) under the urging of the positive pressure from the inlet chamber (14).
