The present invention relates to an air conditioner for a vehicle, which can remarkably improve resistance against an air flow in an air passageway, thereby enhancing efficiency. The air conditioner for a vehicle includes: a case having an air inlet, an air outlet, and an air passageway formed therein; a blower unit for blowing air to the air inlet; and a cooling means and a heating means disposed in the air passageway of the case in an air flow direction in order, wherein the air outlet of the case includes a floor outlet and vent outlets, the floor outlet and the vent outlets are arranged below the heating means in a height direction, and the floor outlet is arranged within a range of the width of the heating means.

A motor vehicle ventilation system configured to ventilate a cabin of the vehicle. The ventilation system comprises a duct extending about a perimeter of the vehicle cabin, at least one air flow inducer configured to induce a flow of air through the duct, the duct comprising an air inlet to receive a bulk flow of air from the flow inducer, and a first opening that extends about the perimeter of the vehicle cabin and that receives air from the duct. The first opening is configured to expel air into the vehicle cabin. The ventilation system further comprises a second opening that extends about the perimeter of the vehicle cabin and that draws air in from the vehicle cabin into a passage extending about the perimeter of the vehicle cabin, wherein a flow through the first opening entrains a flow from the second opening.

A ventilation assembly for a vehicle includes a duct disposed between a seating assembly and a vehicle floor having a first end with a first opening disposed at a first area of the vehicle and a second end with a second opening disposed at a second area of the vehicle. An air mover is disposed at one or more of the first and second ends of the duct, wherein the air mover is operable to move air along the duct.

An on-vehicle air conditioner includes a suction port disposed on a ceiling of a vehicle cabin to suction air within the vehicle cabin, a door discharge port disposed at an upper end of a door opening portion located on a wall face of the vehicle to discharge air downward, and an upper duct configured to guide to the door discharge port the air suctioned by the suction port.

A vehicle includes a front-row occupant support and a rear-row occupant support. The front-row occupant support includes a climate-control system arranged in the front-row occupant support. The climate control system is configured to provide a conditioned airflow moving from the front-row occupant support toward a rear-row occupant region between the front-row occupant support and the rear-row occupant support.

A closed loop cooling system for a junction box in a vehicle includes a junction box housing and a storage compartment for a vehicle. A cool air duct interior volume of a cool air duct and a warm air duct interior volume of a warm air duct are each in fluidic communication with a housing interior volume of the junction box housing and a compartment interior volume of the storage compartment to form a closed loop cooling system. The cool air duct interior volume is sized to convey cool air from a cool air outlet of the storage compartment to a cool air inlet of the junction box housing, and the warm air duct interior volume is sized to convey warm air, which is warmer than the cool air, from a warm air outlet of the junction box housing to a warm air inlet of the storage compartment.

A module for accommodating electronic circuitry which advantageously is able to take advantage of air in a climate system for cooling of the electronic circuitry. In one aspect, there is provided a module for accommodating electronic circuitry in a vehicle, the module includes: at least one attachment surface for attachment of electronic circuitry thereon, an air guiding structure for receiving an air flow for cooling of the attachment surface, the air guiding structure having a wall member including the attachment surface such that the wall member provides a thermal path between the attachment surface and the air in the air guiding structure, wherein the air guiding structure includes an inlet configured to receive air for cooling of the attachment surface wherein the air flow is an air flow used for climate control in the vehicle.

A vehicle air conditioning duct for introducing air from an air conditioner to a rear seat includes: an air intake section; a curved section arranged on a side face of a floor tunnel and connected to a lower part of the air intake section; a main body section connected to a rear part of the curved section and extending toward the vehicle rear along the floor tunnel; and an air discharge section, which is connected to a lower part of a rear end portion of the main body section, and which, at a location under a rear end of a front seat, extends outward in the vehicle width direction, the air discharge section having a blowing outlet for blowing air toward the rear seat.

A vehicle battery protection structure includes a vehicle frame member, a first duct, and a second duct. The vehicle frame member is disposed in a region including a battery. The vehicle frame member has a through hole. The battery is mountable on a vehicle. The first duct is disposed on an outside of the battery at a location oriented toward an outside of the vehicle. The second duct is inserted through the through hole of the vehicle frame member. The second duct is disposed to overlap the first duct in a vertical direction of the first duct on the outside of the battery at the location oriented toward the outside of the vehicle.

A utility vehicle is described having front and rear passenger area, and an HVAC system provides treated air to both front and rear areas. The front area includes a tunnel extending longitudinally rearwardly, and a low profile duct extends within the tunnel to communicate treated air to the rear passenger area. The frame has been modified to mount a drive shaft carrier bearing to maximize the area under the tunnel for hose routing. The frame has been modified to maximize the ingress area for the foot of the rear passenger. The frame has been modified to better seal the vehicle when doors are utilized.
