A heating, ventilation, and air conditioning (HVAC) airflow distribution module including a passenger side face outlet and a passenger center face outlet both defined by the module. A passenger face door sub assembly within the module includes a passenger side face door (outer portion) at the passenger side face outlet and movable to control airflow through the passenger side face outlet. A passenger center face door (inner portion) is at the passenger center face outlet and is movable to control airflow through the passenger center face outlet. The passenger side face door and the passenger center face door are movable independent of one another to independently control airflow through the passenger side face outlet and the passenger center face outlet.

The present disclosure provides an air-conditioning device and an air-conditioning system of an integrated heat exchanger, wherein an integrated heat exchanger for generating heating air or cooling air is used to generate air-conditioning air by utilizing cooling water, thereby securing cooling/heating efficiency. A decreased number of doors are used to adjust the temperature of air-conditioning air with regard to each mode, thus reducing the entire package. In addition, front and rear indoor spaces can be temperature-controlled individually, and comfort can be provided for each passenger seat.

An air conditioning unit includes an air conditioning case, a connector that is attached to an end of a first pipe connected to a first heat exchanger, a second pipe connected to a second heat exchanger, and a gasket being a sheet in shape. The gasket includes a first opening and a second opening. The gasket is adhered to a contact surface of the air conditioning case with the connector inserted into the first opening and with the second pipe inserted into the second opening. The periphery of the second opening in the gasket is compressed by the second pipe. The gasket includes a surface including an adhesive area that includes at least a periphery of the first opening and an adhesive-less area that includes at least a periphery of the second opening. The adhesive is applied to the adhesive area and is not applied to the adhesive-less area.

Disclosed is a vehicle air conditioning device, which is an air conditioning device using an integrated heat pump system, and in which left and right independent air conditionings can be implemented in a simple structure such that the left and right air volumes may be automatically controlled, the ability to mix hot and cold air is improved, and sufficient space can be secured inside a vehicle.

A heating, ventilation, and air conditioning (HVAC) airflow distribution module is integrated with a driver-focus mode operation mechanism for a vehicle. The module utilizes: a driver face door to control airflow through driver face outlets; a passenger face door sub assembly to control airflow through a passenger center face outlet and a passenger side face outlet independently; a foot door sub assembly including a passenger front foot door and a main foot door to control airflow through a passenger front foot outlet independently from driver front and rear foot outlets and a passenger rear foot outlet; and a separator to separate airflow through passenger front and rear foot outlets. The present disclosure enables an HVAC airflow distribution module to focus airflow on the driver's seat and maintain the vehicle recirculation at a comfortable level when no passenger is present.

The invention relates to a multi-zone air conditioning system for vehicles (1) with several air conditioning zones (2), in particular for buses, characterized thereby that an air temperature control unit (3) is implemented to generate simultaneously warm air and cold air, wherein the cold air across a cold air duct (5) and the warm air across a warm air duct (6) extend separated from one another as a double conduit over the length of the vehicle (1) and that decentralized air mixing units (4) with at least one air outlet (20) are disposed along the double conduit and that the air outlets (20) are assigned to the air conditioning zones (2) of the vehicle (1).

An air conditioner for a vehicle which can reduce ventilation resistance and secure a sufficient cross-sectional area of an air outlet to prevent deterioration in air volume. The air conditioner includes: an air-conditioning case having an air passageway formed therein and a plurality of air outlets formed at an exit thereof, and at least one heat exchanger disposed in the air passageway of the air-conditioning case to exchange heat with air passing through the air passageway, wherein the air outlet includes a center vent for discharging air-conditioned wind toward the center of a vehicle width and a side vent for discharging the air-conditioned wind toward the side of the vehicle width, and one between the center vent and the side vent is arranged in an upper side of the air-conditioning case, and the other is arranged in one side of the air-conditioning case in a back-and-forth direction of the vehicle.

A method for servicing a heater core installed in a heating, ventilation, and air-conditioning (HVAC) assembly for a motor vehicle includes removing a sealing attachment from an interfacing connection interfacing with the heater core. The method includes sliding the heater core in a direction of insertion. The method includes disconnecting, from the heater core, the interfacing connection. The method includes removing the heater core in a direction of extraction, the direction of extraction being orthogonal to the direction of insertion.

An air conditioner for a vehicle includes: a casing to accommodate a cooler and a heater; a front temp door disposed in the casing to control a temperature of air supplied to a front seat zone; a rear temp door disposed under the front temp door to control a temperature of air supplied to a rear seat zone; and a rear vent disposed at a lower portion of the casing to discharge air to the rear seat zone. The air conditioner can secure the flow rate of the air that is supplied to the rear seat zone of the interior of a vehicle by improving the route for flow of the air that is supplied to the rear seat zone.

An HVAC module for an automotive vehicle includes a housing defining an air inlet, an upper front zone outlet, a lower front zone outlet, and a rear zone air outlet. An evaporator and a heater downstream of the evaporator are disposed in the housing. The air inlet of the housing is divided by a first divider into an OSA portion exclusively receiving outside air and a REC portion exclusively receiving recycled air. Each of the evaporator and the heater has a respective OSA portion receiving the outside air and a REC portion receiving the recycled air entering the HVAC module through the inlet. A second divider between the evaporator and the heater directs the outside air from the REC portion of the evaporator to the REC portion of the heater. Two temperature doors control access of separate partial streams of the recycled air from the evaporator to the heater.
