A charger cooling air source selection method includes cooling a vehicle battery charger by opening an outside air vent door in a vehicle and drawing outside air through the outside air vent door; determining whether the outside air vent door will close; and if the outside air vent door will not close, establishing and maintaining positive air pressure in a cabin of the vehicle by ensuring an open configuration of a recirculation door in the vehicle.

An air extractor grill for a vehicle may include a housing fixedly mounted at a portion on the vehicle separating inside and outside spaces of the vehicle and provided with through holes having a plurality of grills, an outer cover coupled with one surface of an outside of the housing and having an opened inner space provided with a plurality of outer barrier ribs, and a plurality of valves including upper portions fitted between the housing and the outer cover to be closely disposed to the housing to seal the through holes when the outer cover is connected with the housing, the plurality of valves being operated to open the through holes while lower portions of the plurality of valves rotate toward the outer cover based on the fixed upper portions when air inside the vehicle needs to be discharged to the outside of the vehicle.

An air intake system for a vehicle comprises an exterior air inlet disposed on the vehicle that receives air from an exterior of the vehicle. An air outlet is disposed on the vehicle that supplies air to an engine of the vehicle. A conduit network connects the exterior air inlet and the air outlet. An interior air device disposed on the vehicle is connected to the conduit network allowing air from an interior of the vehicle into the engine. A base plate with an opening is attached to the conduit network. A hatch connected the base plate allows air from the interior of the vehicle through the opening.

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 barrier door may include a section including an outer stationary portion and an inner movable portion disposed within the outer stationary portion, an actuator, and a controller. The actuator may move the inner movable portion between different positions to control flow of air between a protective enclosure and a volume outside of the protective enclosure. The controller may monitor one or more operating characteristics of the actuator and may modify an operational status of the actuator to control the flow of the air between the protective enclosure and the volume outside of the protective enclosure based at least in part on the one or more operating characteristics.

A vehicle air conditioner installed in a vehicle includes a condenser that causes heat exchange between a coolant and outside air, and a spray nozzle that sprays water to a portion near the condenser that are provided in each of a front side accommodation space positioned in a lower front portion of the vehicle and a rear side accommodation space positioned in lower rear portion of the vehicle.

A vehicle ventilation module for allowing air to exhaust from the inside of a vehicle compartment, comprising a carrier element to be mounted to the vehicle, the carrier element comprising: at least one vent opening for allowing air to exhaust from the inside of a vehicle compartment when the vehicle ventilation module is mounted to the vehicle; at least one flap being pivotable about a swivel axis at the carrier element between a close position and an open position, wherein the vent opening is covered by the flap in the close position and is at least partially uncovered by the flap in the open position so that air may flow through the vent opening; and an actuating mechanism coupled to the flap for pivoting the flap about its swivel axis from the close position to the open position. The actuating mechanism is actuated to pivot the flap to the open position by a current applied to the actuating mechanism.

A vehicle interior ventilation apparatus having at least one pressure relief valve, in particular of a first type, which is received and/or fixed in a first receiving opening in a vehicle body component, and having at least one pressure relief valve (10), in particular of a second type that differs from the first type, which is received and/or fixed in a second receiving opening separated from the first receiving opening in a vehicle body component.

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.
