Abstract

An air conditioner installable on a window frame and having a ventilation function. The air conditioner comprises a cabinet comprising a first inlet hole, a second inlet hole and a third inlet hole, a first heat exchanger provided inside the cabinet to allow indoor air, which is introduced through the first inlet hole, to exchange heat, a second heat exchanger provided inside the cabinet to allow outdoor air, which is introduced through the second inlet hole, to exchange heat, and a third heat exchanger provided inside the cabinet to be located between the first heat exchanger and the second heat exchanger in a height direction of the cabinet, and provided to allow outdoor air, which is introduced through the third inlet hole, and condensed water, which is generated in the first heat exchanger, to exchange heat with each other.

First claim

The invention claimed is:

1. An air conditioner, comprising:
a cabinet including a first inlet hole, a second inlet hole and a third inlet hole;
a first heat exchanger provided inside the cabinet to exchange heat with indoor air, introduced through the first inlet hole;
a second heat exchanger provided inside the cabinet to exchange heat with outdoor air introduced through the second inlet hole; and
a third heat exchanger provided inside the cabinet between the first heat exchanger and the second heat exchanger along a height direction of the cabinet, and provided to allow outdoor air introduced through the third inlet hole and condensed water generated in the first heat exchanger to exchange heat with each other,
wherein the condensed water generated in the first heat exchanger is transferred to the second heat exchanger through the third heat exchanger,
wherein the condensed water generated in the first heat exchanger and having passed through the first heat exchanger and condensed water having passed through the second heat exchanger are discharged to an outside of the air conditioner while an operation of the air conditioner is stopped,
wherein the condensed water having passed through the second heat exchanger is condensed water generated in the first heat exchanger, having passed through to the second heat exchanger, and having passed through to the third heat exchanger.

2. The air conditioner of claim 1 , wherein
the first heat exchanger comprises a water collecting panel in which the condensed water generated in the first heat exchanger is collected,
wherein the condensed water collected in the water collecting panel is moved to the third heat exchanger while the third inlet hole is open.

3. The air conditioner of claim 1 , wherein the second heat exchanger comprises:
a distribution panel comprising a plurality of condensate distribution holes to allow condensed water, which passed through the third heat exchanger, to be distributed to the second heat exchanger, the distribution panel disposed on an upper end of the second heat exchanger; and
a water collecting panel disposed at a lower end of the second heat exchanger to collect condensed water passed through the second heat exchanger.

4. The air conditioner of claim 1 , further comprising:
a damper configured to selectively open and close the third inlet hole.

5. The air conditioner of claim 4 , further comprising:
a filter which is replaceable and disposed between the damper and the third heat exchanger.

6. The air conditioner of claim 1 , wherein
the cabinet further comprises a first outlet hole provided to allow air, which passed through the first heat exchanger, to be discharged into an indoor space,
wherein the air conditioner further comprises:
a first duct provided to connect the first inlet hole, the third inlet hole, and the first outlet hole, so as to allow the indoor air, which is introduced through the first inlet hole, to be discharged to the first outlet hole, and to allow the outdoor air, which is introduced through the third inlet hole, to be discharged to the first outlet hole.

7. The air conditioner of claim 6 , further comprising:
a first fan installed in the first duct to move the air, which passed through the first heat exchanger, to the first outlet hole.

8. The air conditioner of claim 6 , wherein
the cabinet further comprises a second outlet hole provided to allow air, which passed through the second heat exchanger, to be discharged to an outdoor space,
wherein the air conditioner further comprises:
a second duct provided to connect the second inlet hole to the second outlet hole, so as to allow the outdoor air, which is introduced through the second inlet hole, to be discharged to the second outlet hole.

9. The air conditioner of claim 8 , wherein
the first duct and the second duct are separated from each other to prevent air moving along the first duct and air moving along the second duct from mixing with each other.

10. The air conditioner of claim 8 , further comprising:
a second fan installed in the second duct to move the air, which passed through the second heat exchanger, to the second outlet hole.

11. The air conditioner of claim 1 , further comprising:
a compressor provided inside the cabinet below the second heat exchanger along the height direction of the cabinet, the compressor being connected to the first heat exchanger and the second heat exchanger, respectively.

12. An air conditioner comprising:
a cabinet including a first inlet hole, a second inlet hole and a third inlet hole, the first inlet hole, the second inlet hole and the third inlet hole being configured to be opened and closed;
a first heat exchanger provided to exchange heat with indoor air introduced through the first inlet hole;
a second heat exchanger provided to exchange heat with outdoor air introduced through the second inlet hole; and
a third heat exchanger located between the first heat exchanger and the second heat exchanger, and provided to allow outdoor air introduced through the third inlet hole and condensed water generated in the first heat exchanger to exchange heat with each other while the third inlet hole is open,
wherein the condensed water generated in the first heat exchanger is transferred to the second heat exchanger through the third heat exchanger,
wherein the condensed water generated in the first heat exchanger and having passed through the first heat exchanger and condensed water having passed through the second heat exchanger are discharged to an outside of the air conditioner while an operation of the air conditioner is stopped,
wherein the condensed water having passed through the second heat exchanger is condensed water generated in the first heat exchanger, having passed through to the second heat exchanger, and having passed through to the third heat exchanger.

13. The air conditioner of claim 12 , wherein
the first heat exchanger, the second heat exchanger, and the third heat exchanger are provided inside cabinet so that the third heat exchanger is located between the first heat exchanger and the second heat exchanger along a height direction of the cabinet.

14. The air conditioner of claim 12 , further comprising:
a damper configured to selectively open and close the third inlet hole.

15. The air conditioner of claim 14 , further comprising:
a filter which is replaceable and disposed between the damper and the third heat exchanger.

16. The air conditioner of claim 12 , wherein
the cabinet further comprises a first outlet hole provided to allow air, which passed through the first heat exchanger, to be discharged into an indoor space,
wherein the air conditioner further comprises:
a first flow path provided to allow indoor air, which is introduced into the first inlet hole, to be discharged to the first outlet hole by passing through the first heat exchanger; and
a second flow path provided to allow outdoor air, which is introduced into the third inlet hole, to be discharged to the first outlet hole by sequentially passing through the third heat exchanger and the first heat exchanger, and connected to the first flow path through the first heat exchanger.

17. The air conditioner of claim 16 , wherein
the cabinet further comprises a second outlet hole provided to allow air, which passed through the second heat exchanger, to be discharged to an outdoor space,
wherein the air conditioner further comprises:
a third flow path provided to allow outdoor air, which is introduced into the second inlet hole, to be discharged to
