In the case where the rear seat air volume discharging structure is combined with the console vent and the center pillar vent as described above, the air volume distribution ratio between the console vent and the center pillar vent is fixed at 50:50, which causes the following problems.
First, if the air-conditioning airflow distribution is 50:50 between the console vent and the center pillar vent during the summer season, there is a problem that the discharge temperature increases due to the heat loss of the discharge air volume through the center pillar vent duct or the like.
That is, since the flow path from the air conditioner to the center pillar vent grill is long and the cent filler vent flow path is adjacent to the outside air (high temperature during the summer season), a cold airflow loss is generated, There is a problem that the temperature of the airflow increases.
Accordingly, as the air volume distribution between the console vent and the center pillar vent is 50:50 during the summer season, the average indoor temperature in the backstroke (behind the driver's seat / passenger's seat) ≪ / RTI > < RTI ID = 0.0 > C, < / RTI >
Second, if the heater airflow distribution is 50:50 between the console vent and the center pillar vent during the winter season, there is a problem that the discharge temperature is lowered due to heat loss of the discharge air volume through the center filler vent duct or the like.
That is, since the flow path from the air conditioner to the center pillar vent grill is long and the cent filler vent flow path is adjacent to the outside air (low temperature during the winter season), heat loss of warm air volume is generated, There is a problem in that the temperature of the wind volume becomes lower and the cold wind is discharged.
Accordingly, since the air volume distribution between the console vent and the center pillar vent is 50:50 during the winter season, the air volume temperature discharged through the console vent grill and the air volume discharged through the center pillar vent grill differ by about 15 ° C or more So that the heating efficiency of the rear seat space is deteriorated.
Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a ventilation system for an air conditioner, The present invention has been made in view of the above problems, and it is an object of the present invention to provide an air conditioner control method for an automotive air conditioner,
According to an aspect of the present invention, A first airflow distribution variable control step of distributing the air volume discharged through the console vent more compared to the air volume discharged through the center pillar vent when the room temperature is equal to or higher than the first reference temperature; Measuring an outside air temperature; A second airflow distribution variable control step of distributing more the air volume discharged through the console vent than the air volume discharged through the center pillar vent when the outside temperature is below the second reference temperature; And a control unit for controlling the air conditioner.
Preferably, the air volume discharged through the console vent and the air volume discharged through the center pillar vent are distributed to the level of 60-70: 30-40 in the first air volume distribution variable control step.
In addition, in the second variable air amount distribution control step, the air volume discharged through the console vent and the air volume discharged through the center pillar vent are distributed to the level of 100 to 90: 0-10.
When the room temperature is lower than the first reference temperature or higher than the second reference temperature, the air volume discharged through the console vent and the air volume discharged through the center pillar vent are distributed and maintained at 50:50.
The first air volume distribution variable control step may be performed for a predetermined time period in which the indoor temperature is equal to or lower than the first reference temperature and the second air volume distribution variable control step may be performed during a predetermined time period in which the outdoor air temperature is equal to or higher than the second reference temperature .
Through the above-mentioned means for solving the problems, the present invention provides the following effects.
First, during the summer season, the air distribution between the console vent and the center pillar vent is controlled at a level of 60 ~ 70: 30 ~ 40 for a certain period of time, so that more air conditioner air is discharged through the console vent, It is possible to improve performance (short-term effectiveness).
Second, during the winter season, the air distribution between the console vent and the center pillar vent is controlled to a level of 100 ~ 90: 0 ~ 10 for a certain time, so that more heater air volume is discharged through the console vent, It is possible to improve performance (short-term effectiveness).

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As described above, a console vent and a center pillar vent are combined as a blowing path of the air conditioner to improve the cooling / heating performance of the rear seat space.
Since the center pillar vent has an air flow path from the air conditioner to the center pillar through the inside of the front door, the air flow path is long and is in a state adjacent to the outside air.
Accordingly, in the summer, a cool air amount of heat loss is generated due to the operation of the air conditioner due to the long air path of the centipillar vent and its proximity to the outside air (high temperature during the summer season), and the temperature of the finally discharged air amount through the center filler vent grille There is a problem that it increases.
On the other hand, during the winter season, when the cent filler vent flow path is long and adjacent to the outside air (low temperature during the winter season), the heat loss due to the heater operation is generated and the temperature of the final discharged air amount through the center filler vent grille There is a problem that the cold wind is discharged.
In the present invention, the air flow distribution between the console vent and the center pillar vent is variably controlled during the winter season and the summer season, and variable control is performed to increase the air volume through the console vent compared to the air volume through the center pillar vent, The point is that there is one thing to be done.
Hereinafter, a method of controlling the air conditioner air volume according to the present invention will be described.
FIG. 3 is a flowchart illustrating an air conditioner control logic for an automotive vehicle according to the present invention, and FIG. 4 is a flowchart illustrating an air condition control process in a summer season in a method of controlling an air conditioner apparatus for an automobile according to the present invention.
When the indoor temperature is measured at a temperature sensor (INCAR sensor) for measuring the indoor temperature of the vehicle, if the indoor temperature is higher than the first reference temperature (for example, 32 DEG C), the air conditioner controller determines that the indoor pillar vent The first air volume distribution variable control is performed to distribute the air volume discharged through the console vent to a greater extent than the air volume discharged through the console vent.
Preferably, the first air volume distribution variable control by the air conditioner controller is performed by distributing the air volume discharged through the console vent and the air volume discharged through the center pillar vent to a level of 60-70: 30-40.
For example, the control valve of the air conditioner controller further opens the air volume control valve that flows through the console vent, while the air volume control valve that flows through the center pillar vent further closes the air volume, and the air volume discharged through the console vent and the center pillar vent The amount of air to be blown out can be distributed to the level of 60 ~ 70: 30 ~ 40.
Therefore, the cold air from the air conditioner during the summer season is concentratedly discharged through the console vent grille via the console vent duct, thereby improving the cooling efficiency of the rear passages while minimizing the heat loss of the cold air passing through the center pillar vent duct have.
At this time, the first air amount distribution variable control step is performed for a predetermined time until the room temperature falls below the first reference temperature, and when the room temperature is lower than the first reference temperature, the air conditioner controller discharges the air through the console vent The air volume and the air volume discharged through the center pillar vent are distributed and maintained at 50:50.
FIG. 5 is a flowchart illustrating a process of controlling air volume during the winter season in a method of controlling air volume of an air conditioner for an automobile according to the present invention.
If the outside air temperature is lower than the second reference temperature (for example, 0 ° C) as a result of measuring the outside temperature of the vehicle by the outside temperature sensor, it is determined that the air conditioner controller is in the winter season. The second air amount distribution variable control is performed to distribute the air amount that is discharged through the second air amount distribution unit.
Preferably, the variable air amount distribution control by the air conditioner controller is performed by distributing the air volume discharged through the console vent and the air volume discharged through the center pillar vent to 100 to 90: 0-10 levels.
For example, when the air volume control valve that flows through the console vent is completely opened by the control command of the air conditioner controller and the air volume control valve that flows through the center pillar vent is completely closed, the air volume discharged through the console vent, The amount of air discharged through the vent can be distributed to 100 ~ 90: 0 ~ 10 level.
Therefore, warm air from the heater operation during the winter season is concentratedly discharged through the console vent grille via the console vent duct, thereby enhancing the quick cooling effect of the rear seats while preventing the heat loss of the warm air passing through the center pillar vent duct have.
At this time, the second air amount distribution variable control step proceeds for a predetermined time until the outside air temperature rises to the second reference temperature or more, and when the outside air temperature becomes the second reference temperature or more, And the air volume discharged through the center pillar vent is distributed and maintained at 50:50 again.
Thus, by distributing the airflow distribution between the console vent and the center pillar vent during the summer season to a level of 60 to 70: 30 to 40 for a predetermined time, more air-conditioned air can be discharged through the console vent, And the cooling performance (quick-action) can be improved.
In addition, during the winter season, the air distribution between the console vent and the center pillar vent is controlled to be 100 ~ 90: 0 ~ 10 for a certain period of time to allow more heater air volume to be discharged through the console vent, It is possible to improve performance (short-term effectiveness).
