The present invention relates to an air conditioner for a vehicle, which can send air-conditioned air toward a rear seat of the vehicle in order to perform air-conditioning of a front seat of the vehicle and air-conditioning of a rear seat. The air conditioner includes an air passageway formed in an air-conditioning case, wherein the air passageway includes: a rear seat cold air passageway which is a passageway that the air passed through the heat exchanger for cooling bypasses the heat exchanger for heating and flows toward a rear seat of the vehicle; and a warm air passageway which is a passageway that the air passed through the heat exchanger for cooling passes through the heat exchanger for heating and flows toward a front seat or the rear seat of the vehicle. The air conditioner includes a rear seat temperature adjusting door for controlling an amount of air flowing from the warm air passageway to the rear seat air outlet and an amount of air flowing from the rear seat cold air passageway to the rear seat air outlet.

An air-handling system for a motor vehicle includes a conditioning section having an evaporator core and a heater core. The conditioning section is separated into a primary zone and a secondary zone at a position disposed upstream of the heater core. The heater core extends partially into each of the primary zone and the secondary zone. A primary door assembly is disposed within the conditioning section at a position upstream of the heater core and a secondary door assembly is disposed within the secondary zone of the conditioning section at a position downstream of the primary door and upstream of the heater core.

Disclosed is an air conditioning apparatus for a vehicle, the air conditioning apparatus being applicable to an autonomous vehicle, etc. having console removed therefrom by ensuring a lower space of a driver's seat in a front part of the vehicle and being capable of preventing condensate water from flowing backward. The air conditioning apparatus for a vehicle comprises: an air conditioning case having an air flow path formed therein and a plurality of air discharge ports; and a cooling heat exchanger and a heating heat exchanger provided in the air flow path of the air conditioning case and exchanging heat with the air passing through the air flow path, wherein the air discharge ports include a front seat air discharge port and a back seat air discharge port, and the back seat air discharge port is arranged under the heating heat exchanger in the direction of gravity.

An air handling system of a vehicle includes a main housing interchangeable between a first configuration and a second configuration. The main housing has a primary portion configured to convey a cold air flow and a warm air flow therethrough. A secondary portion is interchangeable between a first plenum in the first configuration of the main housing and a second plenum in the second configuration of the main housing.

A vehicle air conditioner for supplementing and regulating the air volume discharged to front seats and rear seats through a door component that controls a passage, and enabling the length of a package in the direction of a heater core to be reduced. The vehicle air conditioner has an air passage comprising: a front seat air passage through which cold air or hot air is discharged toward the front seats of a vehicle; and a rear seat air passage through which cold air or hot air is discharged toward the rear seats of the vehicle, wherein the front seat air passage comprises a front seat cooling passage and a front seat heating passage, and the rear seat path comprises a rear seat cooling passage and a rear seat heating passage, and includes: a first mixing part in which the cold air of the front seat cooling passage and the hot air of the front seat heating passage are mixed; and a second mixing part in which the cold air of the rear seat cooling path and the hot air of the rear seat heating path are mixed.

Methods and systems are described for air sanitation in vehicles. The system detects a change in a vehicle occupancy in a vehicle. The system then generates an air curtain zone in the vehicle based on the vehicle occupancy. The air curtain zone includes an air curtain to isolate air within the air curtain zone from a portion of the vehicle. The air curtain zone also includes a vent and an air filter to purify air in the air curtain zone.

An air-conditioning unit includes an air-conditioning case including an opening through which air flows, a cooler disposed in the air-conditioning case to cool air flowing to the opening, a heater disposed in the air-conditioning case to heat air flowing to the opening, and an adjusting member disposed to cover the opening and adjusting airflow passing through the opening. The adjusting member is produced separately from the air-conditioning case and includes a first region and a second region. The second region includes a high resistance member giving higher resistance to the airflow than the first region. The first region includes a low resistance member giving lower resistance to the airflow than the second region. The low resistance member is a partition dividing the first region into plural air passing parts through which air flows. The high resistance member is a plate member including a part to interfere the airflow.

Disclosed is a vehicle air conditioner capable of increasing the aft flow effective region of an inner flow path by reducing the space occupied by support parts of doors for opening/closing a plurality of regions. The vehicle air conditioner comprises: an air-conditioning case in which an air flow path is formed; and a cooling heat exchanger and a heating heat exchanger provided in the air flow path of the air-conditioning case, wherein the air flow path is partitioned and divided into a plurality of regions, and has a plurality of doors for opening/closing each region and a shaft for driving the doors, and the distance between one door and the shaft is different from the distance between another door and the shaft.

A multi-zone air conditioner system for large vehicles may include an air conditioning device configured to partition an internal of a vehicle into a plurality of zones to independently cool each zone, a detecting device configured to include a room temperature detector for detecting a room temperature of each zone and a photo detector for detecting an amount of solar radiation, an input device configured to switch an operating state of the air conditioning device to an automatic mode or a manual mode, and a control device configured to generate a control signal for operating the air conditioning device based on a signal transmitted from the detecting device and the input device.

An air conditioning system of a motor vehicle, having a housing with at least two independent air ducts formed therein, which are arranged separately from each other by at least one partition wall in the housing. A cooling heat exchanger is arranged in the housing such that it is flowed through by air, which can flow into the at least two independent air ducts. A heating heat exchanger is arranged in the housing such that it protrudes into the at least two independent air ducts and is flowed through by air of the at least two independent air ducts. The heating heat exchanger being an electrically operable heat exchanger, which is formed with several independently heated heat exchanger areas, so that the air flowing through an heat exchanger area is independently heatable and each independent air duct is provided at least one heat exchanger area.
