Abstract

An air conditioner is disclosed. The air conditioner includes a suction chamber provided with an indoor suction port, through which indoor air is suctioned, an outdoor suction port, through which outdoor air is suctioned, the suction chamber being configured to selectively adjust a ratio of outdoor air to be suctioned to indoor air to be suctioned, an outdoor discharge chamber disposed at one side of the suction chamber, the outdoor discharge chamber being provided with an outdoor discharge port, through which air in the suction chamber is discharged outdoors, and an indoor discharge chamber disposed at the other side of the suction chamber, the indoor discharge chamber being provided with an indoor discharge port, through which air in the suction chamber is discharged indoors. When discharging indoor air, it is possible to adjust a proportion of outdoor air introduced indoors.

First claim

What is claimed is:

1 . An air conditioner comprising:
a suction chamber to selectively adjust a ratio of an outdoor air to be suctioned to an indoor air to be suctioned, the suction chamber being provided with an indoor suction port to suction the indoor air and an outdoor suction port to suction the outdoor air; an outdoor discharge chamber provided at a first side of the suction chamber, the outdoor discharge chamber having an outdoor discharge port to discharge air in the suction chamber to an outdoor location; and an indoor discharge chamber provided at a second side of the suction chamber, the indoor discharge chamber having an indoor discharge port to discharge air in the suction chamber to an indoor location.

2 . The air conditioner of claim 1 , wherein the suction chamber comprises:
a first heat exchange chamber having a first heat exchanger to operate as one of an evaporator and a condenser, the first heat exchange chamber being connected to the outdoor discharge chamber and to the indoor discharge chamber; a second heat exchange chamber having a second heat exchanger to operate as the other of the evaporator and the condenser, the second heat exchange chamber being connected to the outdoor discharge chamber and to the indoor discharge chamber; an outdoor suction selection chamber connected to the outdoor suction port to allow the outdoor air to be introduced therein and to supply the outdoor air to at least one of the first heat exchange chamber and the second heat exchange chamber; and an indoor suction selection chamber connected to the indoor suction port to allow the indoor air to be introduced therein and to supply the indoor air to at least one of the first heat exchange chamber and the second heat exchange chamber.

3 . The air conditioner of claim 2 , wherein the suction chamber further comprises:
a first outdoor suction damper provided between the outdoor suction selection chamber and the first heat exchange chamber to control a flow rate of the outdoor air from the outdoor suction selection chamber to the first heat exchange chamber; and a second outdoor suction damper provided between the outdoor suction selection chamber and the second heat exchange chamber to control a flow rate of the outdoor air from the outdoor suction selection chamber to the second heat exchange chamber.

4 . The air conditioner of claim 2 , wherein the suction chamber further comprises:
a first indoor suction damper provided between the indoor suction selection chamber and the first heat exchange chamber to control a flow rate of the indoor air from the indoor suction selection chamber to the first heat exchange chamber; and a second indoor suction damper provided between the indoor suction selection chamber and the second heat exchange chamber to control a flow rate of the indoor air from the indoor suction selection chamber to the second heat exchange chamber.

5 . The air conditioner of claim 2 , wherein the suction chamber further comprises:
a first outdoor heat exchange damper to selectively open and close the first heat exchange chamber and the outdoor discharge chamber; and a second outdoor heat exchange damper to selectively open and close the second heat exchange chamber and the outdoor discharge chamber.

6 . The air conditioner of claim 2 , wherein the suction chamber further comprises:
a first indoor heat exchange damper to selectively open and close the first heat exchange chamber and the indoor discharge chamber; and a second indoor heat exchange damper to selectively open and close the second heat exchange chamber and the indoor discharge chamber.

7 . The air conditioner of claim 2 , wherein the first heat exchange chamber and the second heat exchange chamber are separated from each other by a heat exchange partition wall.

8 . The air conditioner of claim 2 , wherein the first heat exchange chamber is partitioned into a first inlet chamber and a first outlet chamber by the first heat exchanger, the first inlet chamber being connected to the outdoor suction selection chamber and to the indoor suction selection chamber, and the first outlet chamber being connected to the outdoor discharge chamber and to the indoor discharge chamber.

9 . The air conditioner of claim 2 , wherein the second heat exchange chamber is partitioned into a second inlet chamber and a second outlet chamber by the second heat exchanger, the second inlet chamber being connected to the outdoor suction selection chamber and to the indoor suction selection chamber, and the second outlet chamber being connected to the outdoor discharge chamber and to the indoor discharge chamber.

10 . The air conditioner of claim 1 , wherein the suction chamber comprises:
a damper partition wall for separating an interior of the suction chamber into an upper part and a lower part such that a plurality of suction selection chambers are formed in the upper part of the suction chamber and a plurality of heat exchange chambers are formed in the lower part of the suction chamber; a selection chamber partition wall coupled to an upper side of the damper partition wall for partitioning the suction selection chambers into an outdoor suction selection chamber and an indoor suction selection chamber; and a heat exchange partition wall coupled to a lower side of the damper partition wall for partitioning the heat exchange chambers into a first heat exchange chamber and a second heat exchange chamber, and wherein the first heat exchange chamber has a first heat exchanger to operate as one of an evaporator and a condenser, the first heat exchange chamber being connected to the outdoor discharge chamber and to the indoor discharge chamber, the second heat exchange chamber has a second heat exchanger to operate as the other of the evaporator and the condenser, the second heat exchange chamber being connected to the outdoor discharge chamber and to the indoor discharge chamber, the outdoor suction selection chamber is connected to the outdoor suction port to allow the outdoor air to be introduced therein and to supply the outdoor air to at least one of the first heat exchange chamber and the second heat exchange chamber, and the indoor suction selection chamber is connected to the indoor suction port to allow the indoor air to be introduced therein and to supply the indoor air to at least one of the first heat exchange chamber and the second heat exchange chamber.

11 . The air conditioner of claim 10 , wherein
the outdoor suction selection chamber is provided at upper sides of the first heat exchange chamber and the second heat exchange chamber, and the indoor suction selection chamber is provided at the upper sides of the first heat exchange chamber and the second heat exchange chamber.

12 . The air conditioner of claim 10 , wherein the suction chamber further comprises:
a first outdoor suction damper provided in the damper partition wall to selectively open and close the outdoor suction selection chamber and the first heat exchange chamber; a second outdoor suction damper provided in the damper partition wall to selectively open and close the outdoor suction selection chamber and the second heat exchange chamber; a first indoor suction damper provided in the damper partition wall to selectively open and close the indoor suction selection chamber and the first heat exchange chamber; and a second indoor suction damper provided in the damper partition wall to selectively open and close the indoor suction selection chamber and the second heat exchange chamber.

13 . The air conditioner of claim 12 , wherein
an amount that the first outdoor suction damper is ope
