An open architecture HVAC module is disclosed having a housing defining an air inlet and at least two adjacent air outlets. An evaporator and a heater unit are disposed within the housing. A cold air chamber is defined between the evaporator and heater unit, and a hot air chamber is defined downstream of the heater unit. A partition extends into the cold and hot air chambers from an interior surface of the housing between the two adjacent air outlets. The partition is spaced from the evaporator and heater unit. The partition cooperates with the housing to define a first mixing chamber in fluid communication with the first outlet and a second mixing chamber in fluid communication with the second outlet. A blend valve is disposed in each mixing chambers. The blend valves are configured to selectively direct air flow from the cold and hot air chambers to the air outlets.

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.

Features for a vapor compression system configured to cool and/or cat (i.e. thermally condition) two or more distinct climate controlled vehicle interior components via a common thermal bus are disclosed. Some embodiments employ a single compressor. Some embodiments employ multiple compressors and/or thermal buses, each servicing components located within respective interior thermal zones of a vehicle, for example a front row seat zone, second and/or third row seat zones, and/or an overhead zone and/or a trunk zone.

Disclosed herein is an air conditioner for a vehicle, which can perform a bleeding function to discharge air to a rear seat floor vent in a rear seat vent mode, and optimize the size of an outlet and the shape of doors to adjust a bleeding amount of a rear seat floor. The air conditioner for a vehicle, which includes an air-conditioning case having an air passageway formed therein, and a heat exchanger for cooling and a heat exchanger for heating which are disposed in the air passageway of the air-conditioning case to exchange heat with air passing the air passageway, includes: a front seat temp door for adjusting the degree of opening between a front seat cold air passageway and a part of a warm air passageway; a first rear seat temp door arranged between the heat exchanger for cooling and the heat exchanger for heating to adjust the degree of opening of another part of the warm air passageway; and a rear seat mode door for adjusting the degree of opening of a rear seat air outlet, wherein the rear seat mode door has a rear seat closing function to close an air flow to a rear seat air outlet, and has a bypass part to bleed some of air.

An air conditioner for a vehicle, which includes an air conditioning case having an air passage formed therein, a cooling heat exchanger provided in the air passage of the air conditioning case to heat-exchange with air passing through the air passage, and a heating heat exchanger, comprises: a front seat temperature door which adjusts an opening degree between a front seat cold air passage and a part of a hot air passage; a first rear seat temperature door which is disposed between the cooling heat exchanger and the heating heat exchanger and adjusts an opening degree of another part of the hot air passage; and a second rear seat temperature door which is disposed in the downstream of the heating heat exchanger and adjusts an opening degree between the hot air passage and a rear seat cold air passage, wherein the second rear seat temperature door includes an asymmetric dome.

A motor vehicle includes a passenger space and a HVAC system. The HVAC system includes a heater, an air conditioner, and ducts configured to heat and/or cool air to the passenger space. The HVAC system is configured to increase humidity of air while the air is flowing through the HVAC system, and to introduce a sanitizing agent into air while the air is flowing through the HVAC system. A controller is configured to actuate the HVAC system to circulate humidified air containing the sanitizing agent through the passenger space to neutralize pathogens that may be present in the passenger space.

An air conditioning case configuring a vehicular air conditioning device is configured from first through third case sections capable of being divided in a width direction, the third case section in a center in the width direction and the first case section being connected via a first dividing section, and the third case section and the second case section being connected via a second dividing section. Moreover, the first and second dividing sections are formed in such a manner that their lower section sides facing a lower passage divided in a space between an evaporator and a heating unit are positioned on outer sides in the width direction with respect to an upper section of the air conditioning case provided with a vent blast port blasting air into a vehicle interior.

A vehicle HVAC system includes: a casing to direct air from outdoors into the interior of a passenger compartment, an air blower blowing the air into the casing, an evaporator disposed in the casing, a heater core disposed downstream of the evaporator, and front and rear seat side temperature doors disposed between the evaporator and the heater core. A method for controlling the HVAC system includes: determining, by a controller, whether a required temperature for cooling rear seats is set to be lower than a required temperature for cooling front seats after an outdoor condition of a vehicle meets a reference high temperature condition; and lowering, by the controller, a target temperature of the evaporator based on the set required temperature for cooling the rear seats when the required temperature for cooling the rear seats is set to be lower than the required temperature for cooling the front seats.
