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.

For air-conditioning within a vehicle interior of a motor vehicle, an air vent is provided with at least one air-directing device located in the region of an air outlet opening. The air vent is configured to allow air flowing out of the air outlet opening to flow, by way of the Coanda effect, in a directed manner along a surface which is adjacent to the air outlet opening. The air-directing device and the adjacent surface are inclined in relation to each other by an angle of inclination which is between 23° and 27°, and the directed air has a volumetric flow of between 30 m.sup.3/h and 700 m.sup.3/h.

The invention relates to an air-conditioning device (1) for a motor vehicle, comprising an element for circulating air towards an evaporator (4), characterised in that the device (1) also comprises a bypass circuit (9) allowing air circulation between a zone located upstream of the evaporator (4) and a zone located downstream of the evaporator (4), the air bypass circuit (9) being arranged above the evaporator (4).

A device for distribution of conditioning air for vehicle turret comprises at least one air duct sheath, the sheath comprising a chute adapted to be made integral with the vehicle and a shutter adapted to be made integral with the turret. The sheath is the form of an arch of circle coaxial with the rotation axis of turret. The device comprises at least one duct in the form of an arch of circle having the same average radius as that of the sheath and able to slide with respect to the sheath between a closed position in which the duct connects one end of the sheath to another end of said sheath, or to another sheath, for continuity of airflow between the sheaths, and an open position in which the duct is slid within the sheath so as to leave a passage transverse to the sheath along a circular sector.

A vehicle air-conditioning unit includes an air-conditioning case, a heater, and an opening-closing device. The air-conditioning case includes a first air passage, a second air passage and a third air passage provided in parallel with each other. The heater is provided in the third air passage and heating the air flowing in the third air passage. The opening-closing device opens and closes the third air passage on a downstream side of the heater. The third air passage includes an opening hole that is an opening end of the third air passage on an upstream side of the heater, and the air-conditioning case includes a hole separation portion dividing the opening hole of the third air passage into a plurality of separation holes.

A foam duct is provided. Among other applications, it may be used in automotive HVAC systems. The method of making this duct reduces material waste and provides an unexpectedly reliable joint in a duct at a sharp or rounded corner. In place, the airflow further supports the joint. In the method, a first portion of a hollow pre-duct is joined with a second portion of a hollow pre-duct by bending the portions at a cut-out positioned between the portions. The bending is complete when the portions form a mechanical connection, which may be signaled by tactile or audible feedback.

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.

A ventilation duct for a motor vehicle includes an air inlet, a duct body, and a duct opening generally in a shape of a quadrilateral having first, second, third, and fourth sides. The duct opening further includes a generally L-shaped extension extending away from the first and second sides of the duct body, and a first seal attached to the L-shaped extension. The ventilation duct further includes an outlet generally in the shape of the quadrilateral of the duct opening. The outlet further includes an outlet assembly, a generally L-shaped seal extension, and a second seal affixed to the L-shaped seal extension. The outlet is installed in the duct body in a direction perpendicular to the airflow to maintain the seal around the assembly point.
