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 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.

A motor vehicle is provided in which cold air is prevented from flowing forwards from the rear region to the front seats when travelling with an open top. At least one air outlet opening or air outlet nozzle is formed at a rear end of the center console, through which air outlet opening or air outlet nozzle warm air can flow out upwards and/or forwards between the two backrests of the two front seats. Further air outlet openings are provided in the two opposite B body pillars, through which air outlet openings warm air can flow out forwards in the direction of the backrests of the front seats and/or in the transverse direction of the vehicle into the rear region.

A vehicle comprising, a passenger cabin, a door to the passenger cabin, and an air conditioning system is disclosed. The air conditioning system comprise a Peltier device, a blower for directing an airflow over a first side of the Peltier device and ducting for ducting air to the blower, the ducting comprising an inlet located on an underside of the door.

A vehicle comprising a passenger cabin and an air conditioning system is disclosed. The air conditioning system comprises a Peltier device, a first blower for directing a first airflow over a first side of the Peltier device, and a second blower for directing a second airflow over a second side of the Peltier device. The second blower draws the second airflow from inside the passenger cabin, and the second airflow is discharged to outside the passenger cabin.

A natural ventilator is herein disclosed that is free of moving parts, wind-activated, rain-proof, and free of dust or smog infiltration. It is not only suitable to be a standalone natural ventilator, but is also advantageous to be used as an enhanced exhaust exit in a forced-air ventilation system, for such enclosed spaces or objects as buildings and vehicles needing air relief. The ventilator assembly has rainwater-proof shapes or fixtures that serve to defend the vent system, and the interior space being vented, against rainwater invasion, even if raindrop trajectory becomes highly oblique from vertical as driven by strong winds. It also includes shapes or fixtures to prevent fume condensation from drifting outward and staining the exterior of a building or vehicle, or the like, that is being vented.

An air conditioning system for a vehicle may include a front Heating, Ventilation, and Air Conditioning (HVAC), a rear extension duct for supplying air from the front HVAC to a rear seat, a rear blower disposed in a middle of the rear extension duct to blow air drawn in through the rear extension duct from the front HVAC, a vent duct branched from the rear extension duct to discharge air blown by the rear blower to a rear interior space of the vehicle through a vent grille, a rear floor duct branched from the vent duct to discharge air supplied through the vent duct to the rear interior space, and an air direction adjustment door to adjust a direction of air and a volume of the air for the vent duct extending to the vent grille and the rear floor duct extending to the discharge port, and an actuator thereof.

A vehicle including a passenger cabin and a vent assembly is a disclosed. The vent assembly includes a duct for carrying an airflow and having an outlet through which the airflow is discharged into the passenger cabin; a deflector located within the duct, the deflector having a convex surface across which the airflow passes; and a valve extending around at least part of the convex surface for restricting the direction of the airflow across the convex surface. The airflow is discharged through the outlet in a direction defined by the direction of the airflow across the convex surface; and the valve is rotatable to vary the direction of the airflow across the convex surface.

A road vehicle having: two front wheels; two rear wheels; an engine, which transmits the motion to drive wheels; and a cooling system, which is connected to the engine. The cooling system has: a cooling circuit where a cooling liquid flows; two first radiators, which are connected to the cooling circuit and make up, together, a first “V”-shaped structure, which is arranged on a right side of the road vehicle; and two second radiators, which are connected to the cooling circuit and make up, together, a second “V”-shaped structure, which is arranged on a left side of the road vehicle.

Casing (30) intended to be mounted on a motor vehicle door, the casing (30) comprises a first air inlet (35) for admitting a first air flow (FR) into the casing (30), an air outlet (36), a chamber delimited by at least one partition, arranged inside the casing (30), a second air inlet (39) for directly admitting a second air flow (FE) into the chamber.
