An air conditioner for a vehicle and a method of controlling the air conditioner to variably control a position of a rear seat cold air control door depending on a position of a front seat temperature-adjusting door. The position of the rear seat cold air control door is controlled according to rear seat air-conditioning modes (rear seat temperature-adjusting modes). In an air-conditioning case, the rear seat cold air control door is mounted on a rear seat air passageway, thereby distributing an optimal volume of cold air to the front seat air passageway and the rear seat air passageway by preventing a large volume of cold air from being supplied to the rear seat air passageway in the rear seat temperature-adjusting mode, securing linearity of temperature discharged to the rear seat.

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.

A vehicle includes an air conditioning system, a high voltage equipment, a cooling fan, and an intake duct. The air conditioning system is to condition air in an interior of the vehicle which has a vehicle height direction. The cooling fan is to send cooling air which has passed through the air conditioning system to the high voltage equipment. The cooling fan has an intake port. The intake duct is connected to the intake port from upward in the vehicle height direction to supply the cooling air to the cooling fan. A lowermost part of the intake port in the vehicle height direction is positioned higher than a lowermost surface of a duct flow path of the intake duct in the vehicle height direction.

An HVAC assembly for conditioning air within a vehicle passenger cabin. The assembly includes a housing, at least one front air inlet and at least one front air outlet for conditioning air at a front of the cabin, at least one rear air inlet and at least one rear air outlet for conditioning air at a rear of the cabin, and a heater core. A cover is configured to: be mounted to an exterior of the housing over at least one heater core conduit; direct airflow exiting the housing to the at least one heater core conduit to permit heat transfer from heated coolant flowing through the at least one heater core conduit to the airflow to heat the airflow; and direct the heated airflow out from within the cover towards the at least one rear air inlet to mix with air exiting the at least one rear air inlet.

HVAC module has an air inlet, an evaporator downstream of the blower and a heater downstream of the evaporator, and a rear mixing zone downstream of the evaporator and the heater, wherein a control valve prevents cold air from flowing back towards the hot air by regulating the pressure of the cold air. A method is devised to control anti-backflow control valve of such an HVAC module by the steps of reading pressure and temperatures at various points in the HVAC module; setting air flow and temperature discharge targets; calculating the resistance of the control valve and a bland valve; determining corresponding control valve and blend valve positions; and moving the control valve and blend valve to those corresponding positions.

An air conditioning system for motor vehicles is designed to independently cool or heat a plurality of vehicle room regions and to independently adjust discharged air volume levels in the respective vehicle room regions. The air conditioning system includes a control unit configured to, when one of the discharged air volume levels in the respective vehicle room regions is set to a maximum air volume level, dependently control the other discharged air volume level to the maximum air volume level while entering into a maximum air volume control mode.

A first battery provided behind seatbacks of rear seats and a second battery provided between the rear seats are arranged in a T-letter shape in a plan view, right-and-left both end portions of the first battery are fixed to a baggage-compartment part of a floor, a front end portion of the second battery extending forward beyond a kick-up portion toward an inside of a front-seat center console is fixed to the floor, and each back face portion of the respective seatbacks of the rear seats which are positioned in a forward-folded state and an upper face portion of the first battery are configured to form a substantially flat and enlarged floor surface of a baggage compartment.

A center console includes a console body which has a pair of side wall parts, and an AT finisher which is provided between upper ends of the pair of side wall parts. An electric AT device is mounted on a lower surface side of the AT finisher directly or through a mounting bracket. A rigid member is mounted in at least one inner surface of the pair of side wall parts. A device holding part which is supported by an upper portion of the rigid member is provided in the mounting bracket or the electric AT device.

Rear console duct air flow of an air conditioner for a vehicle is provided. An inlet of the rear console duct which is in fluid communication with a rear console register is located at a position where conditioned-air which passes through an evaporator and a heater core flows. The inlet of the rear console is always opened such that the conditioned-air is always introduced into the rear console duct when the air conditioner is operated. A guide member, which guides the conditioned-air to the rear console register through the rear console duct, is disposed between the rear console duct inlet and a face duct inlet that is in fluid communication with a face register. An end of a face door selectively contacts the guide member selectively contacts the guide member when the face door makes a turning movement.

An air-delivery system, for use in a vehicle. The system includes a backrest of a vehicle seat assembly and an air-delivery port connected to or integral to the backrest. The system also includes an input conduit connected to the air-delivery port for delivering air received from an air source to the air-delivery port. The air-delivery port is configured and arranged in the backrest facing a generally aft direction to, during operation of the system, deliver air received from the air source aftward from the backrest.
