Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a configuration diagram of a vehicle air conditioning system according to an embodiment of the present invention, FIG. 2 is a heating mode operation state view of a vehicle air conditioning system according to an embodiment of the present invention, 4 is a view showing a guide rib 215 of a vehicle air conditioning system according to an embodiment of the present invention. FIG. 5 is a view showing a guide rib 215 of a vehicle air conditioning system according to another embodiment of the present invention And FIGS. 6 to 7 are views of guide ribs 215 of a vehicle air conditioning system according to another embodiment of the present invention.

The air conditioning system for a vehicle according to the present invention is provided with a cooling duct 101, a cooling inlet port 103 formed on one side of the cooling duct 101, a cooling side indoor outlet 105 and a cooling- A cooling module in which a cooling outdoor outlet 107 is formed and an evaporator 109 is installed in the cooling duct 101; A heating duct 201 is provided and a heating side inlet 203 is formed on one side of the heating duct 201 and a heating side indoor outlet 205 and a heating side outdoor outlet 207 are provided on the other side of the heating duct 201 A heating module provided with a heating side exhaust control door 213 for adjusting the flow rate of the inside and outside of the room between the indoor air outlet and the outdoor air outlet and a condenser 209 inside the heating duct 201; A blower that forms a flow in the cooling duct (101) or the heating duct (201); Side outdoor air outlet 207 of the heating-side air conditioning door 213. The direction of the air flow during the outflow of the heating airflow is directed in the direction away from the cooling-side indoor air outlet 105 And a guide rib 215 for guiding the guide ribs.

The condenser 209 provided inside the heating duct 201 and the eva core 109 provided inside the cooling duct 101 can be connected to one refrigerant channel.

The present invention can provide a cooling duct (101) and a heating duct (201) in a separate space apart from the structure in which both the eva core (109) and the condenser (209) are disposed in one duct in the conventional air conditioning system, It is a structure that reduces interference between air conditioning air. This makes it possible to reheat the cooled air or prevent the heated air from being re-cooled, thereby improving the efficiency of the air conditioning system. Also, since the outlets of the cooling ducts 101 or the heating ducts 201 are separately provided as indoor outlets and outdoors outlets, the air-conditioned air is not always supplied only to the room, but may be discharged outdoors.

This is because the existing air conditioner system performs cooling and heating separately through the cooling cycle using the coolant and the heating cycle using the engine coolant water. Therefore, since the cooling and heating are both performed in one coolant circulation line, Is a required structure due to the characteristics that occur simultaneously.

When the air conditioning system is operated in the cooling mode, air cooled and air-conditioned through the EVA core 109 is discharged to the room, but the air-conditioned air will be discharged to the outside. At this time, if the discharged air-conditioning air is discharged to the cooling-side indoor outlet 105, the temperature of the air supplied to the room is increased to adversely affect the efficiency of the air-conditioning system. Accordingly, in the present invention, the guide ribs 215 are provided so that the direction of the air flow is guided in the direction away from the cooling side indoor outlet 105 when the air heated and ventilated outdoors.

This is the same as when the air conditioning system is operated in the cooling mode. When the air conditioning system operates in the heating mode, the air that has been heat-exchanged through the condenser 209 is discharged to the room, but the air-conditioned air is discharged to the outside. At this time, if the discharged cooling air conditioning air is discharged to the heating side indoor outlet 205, the temperature of the air supplied to the room is lowered, and the efficiency of the air conditioning system is adversely affected. Therefore, in the present invention, the guide ribs 215 are provided so that the direction of the air flow is guided in a direction away from the heating-side indoor air outlet 205 when the air cooled and air-

Further, the present invention can control indoor supply or outdoor exhaust of conditioned air through the air conditioner side air conditioner door 113 and the air conditioner side air conditioner door 213, The exhaust control door 213 can be adjusted to control the mixing ratio of the air that is air-conditioned by the cooling module or the heating module.

And may be formed so as to protrude toward the respective outdoor outlets by sharing the rotation axis with the heating side exhaust control door 213 or the cooling side exhaust control door 113. The exhaust control door may be formed so as to protrude from the both sides of the exhaust control door, May be formed.

A plurality of guide ribs 215 are arranged at regular intervals so that when the ventilation holes 217 are viewed along the longitudinal direction of the exhaust control door, the guide ribs 215 are arranged so as to intersect with each other, It is possible to prevent the occurrence of turbulent flow and smooth exhaust.

4, in the case of the guide rib 215 where the air to be discharged first faces, a ventilation hole 217 is provided on the side of the exhaust control door which is most likely to generate turbulence due to the passage change, The ventilation holes 217 are provided on the opposite sides of the guide ribs 215 on the side of the exhaust control door so that the air that has passed through the ventilation holes 217 of the first guide ribs 215 is guided to the outdoor outlet And the like.

Side exhaust control door 213 is a slide type door and the guide rib 215 is continuously connected to one end of the exhaust side exhaust control door 213. The heating side exhaust control door 213 is a slide- The guide ribs 215 can close a part of the heating-side outdoor air outlet 207 when the heating-side indoor air outlet 205 is completely closed.

And a sliding door structure in which the heating side exhaust control door 213 and the guide rib 215 are connected to each other. 6 to 7, when it is necessary to exhaust the air generated from the heating duct 201 to the outside, the sliding door is slid inside the heating duct 201 to close the indoor outlet of the heating duct 201 do. At this time, a part of the end of the sliding door remains to close a part of the outdoor outlet of the heating duct (201). It is possible to switch the flow direction of the air discharged by this portion.

In the case of using the aforementioned protruding guide ribs 215, it is necessary to consider a space as much as the protruded guide ribs 215 when arranging the air conditioning system in the interior of the vehicle. However, when using the sliding door structure, It is not necessary to secure the space of the display device.

And a control unit 300 for controlling the operation states of the cooling side exhaust control door 113 and the heating side exhaust control door 213. When the air conditioner is operated in the heating mode, Side outdoor outlet 207 and the cooling-side exhaust control door 113 can close the cooling-side indoor outlet 105. [0156]

When the maximum heating mode is selected, the heating side exhaust control door 213 closes the heating side outdoor air outlet 207 to allow the heated air to be supplied to the room, and the cooling side exhaust control door 113 is connected to the cooling side indoor outlet 105) so that the cooled air can be exhausted outdoors.
