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.

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 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.

This vehicle cooling device includes a duct communicating with a heating element disposed in a vehicle, an opening provided in the duct, positioned below a seat surface part of a seat disposed above a floor panel, and opening to a passenger compartment, and a fan supplying air suctioned into the duct from the opening to the heating element, in which the opening is positioned on a vehicle-body rear side with respect to a seat fixing part on a vehicle-body front side among seat fixing parts for fixing the seat to the floor panel in a state in which it is disposed on a vehicle-body rear side of a front end of the seat surface part.

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 rear passenger seat air ventilation system for an electric vehicle includes a rigid tunnel positioned within a passenger compartment of the electric vehicle. The rigid tunnel covers a portion of a battery assembly that extends above a floor structure of the electric vehicle such that the passenger compartment is sealed from the battery assembly. The rigid tunnel defines a forward opening and a rear opening connected by a conduit extending along at least a portion of a length of the rigid tunnel. The conduit is disposed within an interior of the rigid tunnel. A center console is positioned above at least a portion of the rigid tunnel. An air supply system interfaces with the forward opening and to deliver air to the conduit. At least one air vent receives air from the conduit and deliver the air to a rear seating area of the passenger compartment.

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 includes a battery module and an exhaust duct to discharge air from the battery module. A first side member is provided along a first side trim to provide a space between the first side member and the first side trim in a vehicle width direction. The space is connected to the battery module via the exhaust duct. A rear seat is provided in a vehicle interior. A first exhaust port is connected to the exhaust duct via the space and provided in the vehicle interior below the rear seat in a vehicle height direction. A second exhaust port is connected to the exhaust duct via the space and provided in the vehicle interior behind the rear seat in a front-rear direction. The air is discharged from the exhaust duct through the first exhaust port and the second exhaust port via the space.

A vehicle includes a floor panel, a battery module, a heater duct, and an exhaust duct. The battery module is disposed on the floor panel under a seat. The heater duct is disposed on the floor panel to discharge air output from an air conditioner through the heater duct. The exhaust duct is provided on the floor panel to discharge air output from the battery module through the exhaust duct. The exhaust duct intersects the heater duct viewed in a height direction of the vehicle.
