Description

TECHNICAL FIELD [0001] The present invention relates to an air conditioner for an automobile,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air conditioner for a vehicle, and more particularly, to a vehicle air conditioner using a two-phase flow and separately controlling the front and rear temperature.

The air conditioner for a vehicle is an automobile interior product installed for the purpose of cooling and heating the interior of the automobile in the summer or winter season, or preventing the front and rear visibility of the driver by removing the winds generated during rainy or winter seasons. Such a vehicle air conditioner generally has a heating device and a cooling device at the same time, and selectively introduces outside air or indoor air, and then heats or cools the air, and blows air into the vehicle interior to cool or ventilate the vehicle interior.

Generally, when the interior of a winter vehicle is heated, a cool outside air is introduced to prevent the castle from being frosted. However, this results in lower indoor air temperature. To solve these problems, an air conditioner for supplying a two-layer flow of supplying outside air to the window glass of the vehicle and supplying the inside air to the inside of the vehicle has been developed.

An example of a vehicle air conditioner for supplying this two-layer flow is shown in Fig. The vehicle air conditioner includes a air conditioning case 1, a blower unit 2 for flowing air provided inside the air conditioning case 1, a cooling heat exchanger 3 for cooling air, a heating heat exchanger 4 for heating air, .

The cooling heat exchanger (3) and the heat exchanger (4) may be arranged to be spaced apart from each other. At this time, the heating heat exchanger (4) is located downstream of the cooling heat exchanger (3) in the flow path of the air.

A temperature control door 5 is also provided for appropriately mixing the air cooled by the cooling heat exchanger 3 and the air heated by the heating heat exchanger 4 to cool and heat the interior of the vehicle to an appropriate temperature.

The air inlet is separated into the outside air inlet 7 and the inside air inlet 8 by the partition 6. The air outlet is provided with a deprost vent 10 and a face vent 11 provided at an upper portion of the air conditioner case 1 and a floor vent 9 provided at a rear lower portion of the air conditioner case 1.

At this time, there is no separate outlet for air conditioning of the rear seats, so air conditioning of the front seats and the rear seats can not be separated. That is, the conventional vehicle air conditioner has a problem that the occupant of the vehicle can not provide the indoor environment of the vehicle requested by the passengers of the front seat and rear seat.

Further, there is a fear that the air is mixed with the minute gap between the partition 6 and the evaporator 3, and when mixing occurs, there is a problem in supplying the double layer flow.

The front floor discharge port 25, the rear vent discharge port 26, and the rear floor discharge port 27 are located at the upper portion of the air conditioner case 20, And may be located at the rear lower portion of the air conditioning case 20.

An evaporator (30) and a heater core (31) are disposed in the air conditioning case (20) for conditioning the air introduced through the air inlet. The evaporator 30 may be installed on the refrigerant circulation line. The air passing through the evaporator 30 and the refrigerant are heat-exchanged in accordance with the circulation of the refrigerant to cool the air.

The evaporator (30) and the heater core (31) are disposed apart from each other in the air conditioning case (20). As shown in FIG. 2, the evaporator 30 is disposed adjacent to the air inlet so that the air introduced through the air inlet passes through the evaporator 30. The heater core 31 is disposed at the rear portion of the evaporator 30 so that the air passing through the evaporator 30 can be heated.

Further, the automotive air conditioning system includes a two-layered bulkhead for supplying a two-layer flow. The two-layer flow barrier is provided so as to divide the internal space of the air conditioning case (20). Particularly, the two-layer flow barrier may extend in the horizontal direction of the air conditioning case 20 so as to separate the inner space of the air conditioning case 20 up and down.

Hereinafter, a line in which the two-layered bulkhead extends horizontally is referred to as a reference line L, which is indicated by a dotted line in the drawing. The horizontal direction is substantially parallel to the direction in which the air is introduced into the air conditioning case 20.

The reference line L may be provided in the horizontal direction of the air conditioning case 20 and the evaporator 30 and the heater core 31 may be installed in the vertical direction of the air conditioning case 20, as shown in the figure. That is, the evaporator 30 and the heater core 31 are installed perpendicular to the direction in which the air flows, so that the contact area with the air can be increased.

The front floor discharge port 25, the rear vent discharge port 26 and the rear floor discharge port 27 are located at the lower portion of the front floor discharge port 25, the rear vent discharge port 26 and the rear floor discharge port 27, do. That is, the double-layer type bulkhead is located below the de-frost discharge port 23 and the front-vent discharge port 24 and is located above the front floor discharge port 25, the rear vent discharge port 26 and the rear floor discharge port 27 .

The two-layer flow barrier includes a first barrier 40, a second barrier 42, and a third barrier 44, which are sequentially disposed along the reference line L. The first partition wall 40 is located between the air inlet and the evaporator 30 and the second partition wall 42 is located between the evaporator 30 and the heater core 31. The third partition wall 44 is located between the heater core 31) and the inner wall of the air conditioning case (20).

The first partition 40 is provided to divide the air inlet upward and downward so as to separate the air introduced through the air inlet. The first partition wall 40 separates the air inlet into a first inlet 21 and a second inlet 22 located below the first inlet 21.

The first inlet 21 and the second inlet 22 may be filled with fresh air and fresh air, respectively. That is, if necessary, the indoor air or the outside air can flow into both the first inlet 21 and the second inlet 22, the outside air flows into the first inlet 21, and the air flows into the second inlet 22 .

The air introduced through the first inlet 21 passes through the upper portion of the evaporator 30 and the air introduced through the second inlet 22 passes through the lower portion of the evaporator 30.

The second partition wall 42 is arranged to close the air passage between the evaporator 30 and the heater core 31.

At this time, the second barrier ribs 42 may be inclined to one side. In detail, one end adjacent to the evaporator 30 may be positioned above the other end adjacent to the heater core 31. [ In addition, the other end of the second partition wall 42 adjacent to the heater core 31 can be bent downward.

This is so that the air introduced through the second inlet 22 flows into the lower portion of the air conditioning case 20 without being mixed with the air introduced through the first inlet 21. The air introduced through the second inlet 22 can naturally flow downward along the inclined and curved second partitions 42.

A temperature control door is located between the evaporator 30 and the heater core 31. The temperature control door adjusts the flow path so that air passing through the evaporator (30) passes or bypasses the heater core (31). Therefore, the temperature control door is provided in the vertical direction of the air conditioner case 20 so as to adjust the air flow path inside the air conditioner case 20.

At this time, one end of the temperature control door adjacent to the second partition wall 42 may be provided with a guide portion inclined toward the air inlet ports 21, 22. This is to allow the air introduced through the first inlet 21 and the air introduced through the second inlet 22 to flow to the lower portion of the air conditioning case 20 without mixing.

The temperature control door may be located above and below the second partition 42. The temperature control door includes a first door 46 located at an upper portion of the second partition wall 42 and a second door 48 located at a lower portion of the second partition wall 42. That is, the first door 46 is positioned above the reference line L and the second door 48 is positioned below the reference line L. [

The first door 46 and the second door 48 may be provided in the form of a slide door. For example, as shown in the drawings, the first door 46 may be provided in the form of a curved slide door, and the second door 48 may be provided in the form of a slide door that can be moved up and down. By way of example, the first door 46 and the second door 48 may be provided in various forms.

The first door 46 and the second door 48 may be installed to be movable between the second partition wall 42 and the inner wall of the air conditioner case 20. [ The first door 46 moves between the upper inner wall of the air conditioning case 20 and the second partition wall 42 and the second door 48 moves between the lower inner wall of the air conditioning case 20 and the second inner wall of the air conditioning case 20, And moves between the partition walls 42.

The air passed through the evaporator 30 bypasses the heater core 31 when one side of the first door 46 and the second door 48 are in contact with the second partition wall 42. [ That is, the first door 46 and the second door 48 shut off the flow path to the heater core 31 and all the air that has passed through the evaporator 30 bypasses the heater core 31.

The air passing through the evaporator 30 can pass through the heater core 31 when one side of the first door 46 and the other side of the second door 48 are in contact with the inner wall of the air conditioner case 20. [ That is, the first door 46 and the second door 48 cut off the flow path for bypassing the heater core 31 and all the air that has passed through the evaporator 30 passes through the heater core 31.

The air having passed through the evaporator 30 flows into any one of the first flow path P1, the second flow path P2, the third flow path P3 and the fourth flow path P4. The first flow path P1 is provided on the upper portion of the heater core 31 to bypass the heater core 31 and the second flow path P2 is provided on the upper portion of the second partition wall 42 to pass through the heater core 31. [ Respectively. The third flow path P3 is provided below the second partition wall 42 so as to pass through the heater core 31 and the fourth flow path P4 is provided below the heater core 31 so as to bypass the heater core 31. [ As shown in FIG.

The first door 46 is installed to open and close the first flow path P1 and the second flow path P2 and the second door 48 opens and closes the third flow path P3 and the fourth flow path P4. .

The first door 46 and the second door 48 may be respectively provided with guide portions. That is, the first door 46 may have a guide portion at a lower portion adjacent to the second partition 42 to guide the air introduced through the first inlet 21 to the upper portion of the second partition 42, The first door 46 may have a guide portion at an upper portion adjacent to the second partition 42 to guide the air introduced through the second inlet 22 to the lower portion of the second partition 42.

Therefore, mixing of the two-layer flow can be prevented in the shape of the second partition wall 42, the first door 46, and the second door 48.

2 to 6 show an embodiment in which the guide portion 49 is provided only in the second door 48, but the first door 46 may also have a guide portion. At this time, the guide portion 49 is provided on the upper portion of the second door 48 at a predetermined angle. The guide portion 49 may be provided in various forms and is illustrated in FIG. 7 as an exemplary embodiment.

The third partition wall 44 is arranged to open and close the air passage P5 between the heater core 31 and the inner wall of the air conditioner case 20. [ Unlike the fixed first and second barrier ribs 40 and 42, the third barrier ribs 44 are installed to move. For example, the third partition wall 44 may be rotatably fixed to the inner wall of the air conditioning case 20 at one side.

The third partition wall 44 is positioned substantially horizontally with the reference line L when the third partition wall 44 closes the air passage P5 between the heater core 31 and the inner wall of the air conditioner case 20. [ The air introduced into the upper part of the first partition wall 40 is discharged to the dispense discharge port 23 and the front vent discharge port 24 and the air introduced into the lower part of the first partition wall 40 passes through the front floor discharge port 25 The rear vent discharge port 26, and the rear floor discharge port 27, respectively.

That is, the air that has passed through the first flow path P1 and the second flow path P2 is discharged through the defrost discharge port 23 and the front vent discharge port 24, and the third flow path P3 and the fourth flow path P4 ) Is discharged through the front floor discharge port 25, the rear vent discharge port 26, and the rear floor discharge port 27.

When the third partition wall 44 opens the air passage P5 between the evaporator 30 and the inner wall of the air conditioner case 20, the air passing through the first to fourth flow paths P1 to P4 is di Out port 23, the front vent outlet 24, the front floor outlet 25, the rear vent outlet 26, and the rear floor outlet 27, respectively.

Various modes of the air conditioner according to the present invention will be described below based on the above description. These modes are illustrative and various modes other than those described below can be realized.

3 is a view showing a vent mode of the air conditioner according to an embodiment of the present invention.

The vent mode is a mode for rapid internal cooling of the vehicle, such as immediately after the summer passenger boarded the vehicle.

At this time, the incoming air can use outside air or air. Use air of low temperature in the outside air and the outside air for rapid cooling. For example, when the inside air of the vehicle is higher in temperature than the outside air, the outside air flows through both the first inlet 21 and the second inlet 22.

The air introduced into the air conditioning case 20 through the first inlet 21 and the second inlet 22 exchanges heat with the evaporator 30. The first door 46 and the second door 48 open the first flow path P1 and the fourth flow path P4 for bypassing the heater core 31 for maximum cooling and the heater core 31 And the third flow path P3. As shown in Fig. 3, one side of the first door 46 and the second door 48 moves to abut the second partition 42.

At this time, the air introduced through the second inlet port 22 by the inclined surfaces of the second partition wall 42 and the second door 48 does not flow upward but flows to the fourth flow path P4.

Accordingly, all of the air that has passed through the evaporator 30 bypasses the heater core 31. At this time, the door 28 opens the front vent discharge port 24 and the rear vent discharge port 26. The third partition wall 44 opens the air passage P5 between the heater core 31 and the inner wall of the air conditioner case 20. [

Therefore, the air that has passed through the evaporator 30 is supplied to the top of the front seat of the vehicle and the top of the back seat through the front vent discharge port 24 and the rear vent discharge port 26. The air supplied to the upper portion of the vehicle can quickly cool the inside of the vehicle. In addition, when the third partition wall 44 opens the air passage P5 and there is no occupant on the back seat or there is a small occupant, the air volume can be maximally supplied to all the seats.

4 is a view showing a mixing mode of the air conditioner according to an embodiment of the present invention.

The mixed mode indicates a general cooling / heating mode, and the air introduced into the air conditioning case 20 can use outside or inside air as needed.

In addition, the first door 46 and the second door 48 open the respective flow paths according to the needs of the occupant, and provide conditioned air according to the target temperature. 4, a part of the air that has passed through the evaporator 30 bypasses the heater core 31 and a part of the air passes through the heater core 31. The first door 46 and the second door 48 are positioned between the inner wall of the air conditioning casing 20 and the second partition wall 42. [

At this time, the door 28 adjusts the opening of the front vent outlet 23, the front floor outlet 24, the rear vent outlet 25, and the rear floor outlet 26 as necessary.

In addition, since the third partition wall 44 closes the air passage P5, the occupant of the all seats and the occupant of the rear seats can receive different conditioned air.

5 is a view showing a two-layer flow mode of a vehicle air conditioning system according to an embodiment of the present invention.

The double layer mode is a mode to prevent the window of the vehicle from being heated during the winter maximum heating.

It is effective to use a relatively high temperature air for rapid heating of a winter vehicle. However, there is a problem of causing glare on the window glass because the water contains a lot of moisture. At this time, it is possible to supply outdoor air not containing much moisture to the window glass side, and to supply a high-temperature indoor air to the passenger side, so that rapid heating can be performed.

Therefore, the outside air flows through the first inlet 21 and the inside air flows through the second inlet 22. [

The air introduced into the air conditioning case 20 through the first inlet 21 and the second inlet 22 exchanges heat with the evaporator 30. The first door 46 and the second door 48 open the second flow path P2 and the third flow path P3 that pass through the heater core 31 for maximum heating, The first flow path P1 and the fourth flow path P4 for bypassing the first flow path P1 and the fourth flow path P4 are closed. As shown in Fig. 5, one side of the first door 46 and the second door 48 moves so as to contact the inner side surface of the air conditioning case 20.

The outside air introduced through the first inlet 21 through the guide portion 49 of the second door 48 is introduced into the second inlet P2 through the second inlet 22 Is separated and flows into the third flow path P3.

All the air that has passed through the evaporator 30 passes through the heater core 31. At this time, the door 28 opens the de-frost discharge port 23, the front floor discharge port 25, and the rear floor discharge port 27. The third partition wall 44 closes the air passage P5 between the heater core 31 and the inner wall of the air conditioner case 20 to prevent mixing of the indoor air and the outside air.

The outside air having passed through the evaporator 30 and the heater core 31 is supplied to the window glass side of the vehicle through the defrost outlet 23 and the inside air passing through the evaporator 30 and the heater core 31 is discharged through the front floor outlet 25 and the rear floor outlet 27 to the lower and upper seats of the vehicle.

The air supplied to the lower part of the vehicle rapidly heats the inside of the vehicle, and the air supplied to the window glass prevents the casting of the window glass.

6 is a diagram illustrating a de-frost mode of a vehicle air conditioning system according to an embodiment of the present invention.

The defrost mode is a mode for preventing the interior of the vehicle from heating and cooling and preventing the window glass from being frosted. Therefore, the outside air flows through the first inlet 21 and the second inlet 22, and passes through the evaporator 30 and the heater core 31.

The door 28 opens the de-frost discharge port 23 so that the air that has passed through the heater core 31 is discharged through the de-frost discharge port 23. At this time, the third partition wall 44 opens the air passage P5 so that the air that has passed through the third flow path P3 is also discharged through the de-frost discharge opening 23. [
