Abstract

An air-conditioning apparatus for a vehicle is provided, including an air-conditioning case with an inlet portion and a discharge port, and a first partition wall partitioning the inner space thereof into a first space portion and a second space portion, a cooling heat exchanger arranged in the air-conditioning case through the first space portion and the second space portion, and connected to the inlet portion, and a heating heat exchanger arranged in the air-conditioning case through the first space portion and the second space portion, where the air-conditioning case includes a second partition wall which partitions the second space portion into a plurality of space portions, and where a first door is arranged in a third space portion from among the plurality of space portions and disposed behind the heating heat exchanger.

Claims (22)

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

an air-conditioning case including an inlet, an outlet, and a first partition wall configured to partition an inner space into a first space portion and a second space portion;

a cooling heat exchanger disposed inside the air-conditioning case and crossing the first space portion and the second space portion; and

a heating heat exchanger disposed inside the air-conditioning case and crossing the first space portion and the second space portion,

wherein the air-conditioning case includes a second partition wall configured to partition the second space portion into a plurality of space portions,

wherein the air-conditioning case includes a first door disposed in a third space portion among the plurality of space portions and disposed at an outlet side of the heating heat exchanger,

wherein the first door adjusts an opening amount of the heating heat exchanger in the third space portion, and

wherein the air-conditioning case includes a second door disposed at an inlet side of the heating heat exchanger in the second space portion, and the first door and the second door are connected to one driving unit including a motor to move together.

2 . The air-conditioning apparatus according to claim 1 , wherein the air-conditioning case includes a first flow path which is disposed below the heating heat exchanger in a vertical direction and through which air not passing through the heating heat exchanger flows.

3 . The air-conditioning apparatus according to claim 2 , wherein, when the second door fully opens the inlet side of the heating heat exchanger and closes the first flow path, the first door fully opens the outlet side of the heating heat exchanger.

4 . The air-conditioning apparatus according to claim 2 , wherein, when the second door fully closes the inlet side of the heating heat exchanger and fully opens the first flow path, the first door is controlled so that the first door fully opens the outlet side of the heating heat exchanger.

5 . The air-conditioning apparatus according to claim 2 , wherein, when the second door partially closes the inlet side of the heating heat exchanger and partially opens the first flow path, the first door partially opens the outlet side of the heating heat exchanger.

6 . The air-conditioning apparatus according to claim 2 , wherein the first door is disposed to adjust an opening amount of the first flow path together with an opening amount of the outlet side of the heating heat exchanger in the third space portion.

7 . The air-conditioning apparatus according to claim 6 , wherein the first door includes a first shaft portion and a door body coupled to be rotated about the first shaft portion, and the door body includes an upper surface, a lower surface, and a side surface connecting the upper surface to the lower surface to form an accommodating space therein.

8 . An air-conditioning apparatus for a vehicle, comprising:

an air-conditioning case including an inlet, an outlet, and a first partition wall configured to partition an inner space into a first space portion and a second space portion;

a cooling heat exchanger disposed inside the air-conditioning case and crossing the first space portion and the second space portion; and

a heating heat exchanger disposed inside the air-conditioning case and crossing the first space portion and the second space portion,

wherein the air-conditioning case includes a second partition wall configured to partition the second space portion into a plurality of space portions,

wherein the air-conditioning case includes a first door disposed in a third space portion among the plurality of space portions and disposed at an outlet side of the heating heat exchanger,

wherein the first door adjusts an opening amount of the heating heat exchanger in the third space portion, and

wherein the plurality of space portions include the third space portion, a fourth space portion, and a fifth space portion, which are partitioned in a lateral direction of the air-conditioning apparatus, and the third space portion is disposed between the fourth space portion and the fifth space portion.
