Abstract

An individual air conditioning apparatus for a vehicle includes: a driver'"'"'s seat air conditioning module and a passenger seat air conditioning module sequentially provided with an evaporation core and a heater core; a first channel that passes through the evaporation core and is connected to an indoor outlet; a second channel that passes through the evaporation core and the heater core and is connected to the indoor outlet; and a temperature control door that opens and closes the first channel and the second channel.

Claims

1. An individual air conditioning apparatus for a vehicle, comprising:

a driver'"'"'s seat air conditioning module configured to be provided with a driver'"'"'s seat air conditioning duct and have one side provided with a driver'"'"'s seat side inlet and another side provided with a driver'"'"'s seat side indoor outlet, the driver'"'"'s seat side inlet being sequentially provided with an evaporation core and a heater core;

a passenger seat air conditioning module configured to be provided with a passenger seat air conditioning duct and have one side provided with a passenger seat side inlet and another side provided with a passenger seat side indoor outlet, the passenger seat side inlet being sequentially provided with the evaporation core and the heater core;

a partition separating the driver'"'"'s seat air conditioning module and the passenger seat air conditioning module;

a first channel configured to pass through the evaporation core to be connected to the indoor outlet;

a second channel configured to pass through the evaporation core and the heater core to be connected to the indoor outlet;

a first temperature control door configured to open or close the first channel; and

a second temperature control door configured to open or close the second channel, wherein the first temperature control door and the second temperature control door pivot on a same rotational axis,

wherein the driver'"'"'s seat side indoor outlet includes a defroster (DEF) outlet at a driver'"'"'s seat side, and the passenger seat side indoor outlet includes a defroster (DEF) outlet at a passenger seat side,

wherein the partition between the DEF outlet at the driver'"'"'s seat side and the DEF outlet at the passenger seat side is open, such that air at the driver'"'"'s seat side flows to the passenger seat side, and

wherein an air guide Is positioned at the DEF outlet at the driver'"'"'s seat side and extends in a direction in which a channel of the DEF outlet at the driver'"'"'s seat side is reduced to increase pressure of air discharged from the DEF outlet at the driver'"'"'s seat side.

2. The individual air conditioning apparatus of claim 1, wherein the driver'"'"'s seat side indoor outlet and the passenger seat side indoor outlet further include a vent outlet and a floor outlet.

3. The individual air conditioning apparatus of claim 2, further comprising:

a door controller configured to control a temperature control door,

wherein the door controller controls the first channel and the second channel of the passenger seat side to be closed when receiving an individual air conditioning signal.

4. The individual air conditioning apparatus of claim 3, further comprising:

a mode door configured to open and close the DEF outlet,

wherein the door controller increases an open value of the mode door when receiving the individual air conditioning signal and an operation signal of a floor mode or a mix mode.

5. A method of controlling the individual air conditioning apparatus for a vehicle of claim 1, comprising the steps of:

an individual air conditioning operation, by a controller, for supplying air-conditioned air to only either one of a driver'"'"'s seat side and a passenger seat side of the vehicle;

sensing, by the controller, an individual air conditioning operation signal;

determining, by the controller, whether the air conditioning apparatus is operated in a defroster (DEF) mode if it is determined that the individual air conditioning operation signal is sensed; and

releasing, by the controller, the individual air conditioning operation for supplying the air-conditioned air to both of the driver'"'"'s seat side and the passenger seat side of the vehicle, if it is determined that the air conditioning apparatus is operated in the DEF mode.

6. The method of claim 5, further comprising the steps of:

determining, by the controller, whether the air conditioning apparatus is operated in a floor mode or a mix mode if it is determined that the air conditioning apparatus is not operated in the DEF mode; and

controlling, by the controller, a mode door,

wherein if it is determined that the air conditioning apparatus is operated in the floor mode or the mix mode, the mode door is controlled to increase an open value.

7. A non-transitory computer readable medium containing program instructions executed by a processor for controlling the individual air conditioning apparatus of claim 1, the computer readable medium comprising:

program instructions that execute an individual air conditioning operation for supplying air-conditioned air to only either one of a driver'"'"'s seat side and a passenger seat side of a vehicle;

program instructions that sense an individual air conditioning operation signal;

program instructions that determine whether an air conditioning apparatus is operated in a defroster (DEF) mode if it is determined that the individual air conditioning operation signal is sensed; and

program instructions that release the individual air conditioning operation for supplying the air-conditioned air to both of the driver'"'"'s seat side and the passenger seat side of the vehicle, if it is determined that the air conditioning apparatus is operated in the DEF mode.
