Abstract

An air-conditioning system is provided that may include a first air-processing apparatus, which includes a first outlet formed to be open toward a floor and a first inlet formed to be open in a direction inclined relative to a direction in which the first outlet is open and is configured to deliver heat-exchanged air to the first outlet, and a second air-processing apparatus, which includes a second outlet formed to be open in a direction parallel to the first outlet and a second inlet formed to be open in a direction parallel to the first inlet and is configured to deliver purified air to the second outlet. The first outlet and the second outlet extend in a lateral direction, and the first air-processing apparatus and the second air-processing apparatus are arranged in the lateral direction.

First claim

What is claimed is:

1 . An air-conditioning system, comprising:
a first air-processing apparatus comprising a first outlet formed to be open toward a floor and a first inlet formed to be open in a direction inclined relative to a direction in which the first outlet is open, wherein the first air-processing apparatus is configured to cause air introduced into the first inlet to exchange heat with a refrigerant and to cause heat-exchanged air to flow to the first outlet, and wherein the first air-processing apparatus further comprises a first pre-filter disposed in the first inlet to remove foreign substances from air flowing into the first inlet; a second air-processing apparatus comprising a second outlet formed to be open in a direction parallel to the first outlet and a second inlet formed to be open in a direction parallel to the first inlet, wherein the second air-processing apparatus is configured to purify air introduced into the second inlet and to cause the purified air to flow to the second outlet, and wherein the second air-processing apparatus further comprises a second pre-filter disposed in the second inlet to remove foreign substances from air flowing into the second inlet; a filter cleaner configured to move over the first air-processing apparatus and the second air-processing apparatus to remove foreign substances from the first pre-filter and the second pre-filter; a guide rail configured to guide movement of the filter cleaner, wherein the guide rail extends continuously along a surface on which the first inlet of the first air-processing apparatus is formed and a surface on which the second inlet of the second air-processing apparatus is formed; and a support rail disposed on an upper side of the guide rail and configured to support movement of the filter cleaner along the guide rail, wherein the first air-processing apparatus is disposed in contact with one side of the second air-processing apparatus, wherein the first pre-filter and the second pre-filter are each located on a lower side of the guide rail, wherein a top roller positioned on an upper portion of the filter cleaner is positioned to contact an inner wall of the support rail, wherein the first outlet and the second outlet extend in a lateral direction, and wherein the first air-processing apparatus and the second air-processing apparatus are arranged in the lateral direction.

2 . The air-conditioning system according to claim 1 , wherein the second outlet is disposed in a direction in which the first outlet extends.

3 . The air-conditioning system according to claim 1 , wherein the first air-processing apparatus further comprises a first louver configured to adjust a direction of air that is discharged through the first outlet, wherein the second air-processing apparatus further comprises a second louver configured to adjust a direction of air that is discharged through the second outlet, and wherein the first louver and the second louver are individually operated.

4 . The air-conditioning system according to claim 3 , wherein each of the first louver and the second louver comprises:
a louver rotational shaft disposed at a front side of a corresponding one of the first outlet and the second outlet; and a plurality of vanes arranged in a radial direction based on the louver rotational shaft.

5 . The air-conditioning system according to claim 4 , wherein the first air-processing apparatus further comprises a first louver actuator configured to drive the first louver, wherein the second air-processing apparatus further comprises a second louver actuator configured to drive the second louver, and wherein each of the first louver actuator and the second louver actuator is connected to a corresponding one of the first louver and the second louver at a position spaced apart from the louver rotational shaft in the radial direction.

6 . The air-conditioning system according to claim 1 , wherein the first inlet is formed in a portion of a surface of the first air-processing apparatus that extends in a direction perpendicular to the floor, wherein the second inlet is formed in a portion of a surface of the second air-processing apparatus that extends in a direction perpendicular to the floor, wherein the first pre-filter is configured to be withdrawn out of the first air-processing apparatus in a downward direction, and wherein the second pre-filter is configured to be withdrawn out of the second air-processing apparatus in the downward direction.

7 . The air-conditioning system according to claim 6 , wherein the guide rail is disposed above the first inlet and the second inlet.

8 . The air-conditioning system according to claim 1 , wherein the filter cleaner comprises a sensor configured to confirm a position of the filter cleaner, wherein the guide rail is provided with at least one object to be sensed with which the sensor reacts in order to confirm a position of the filter cleaner, and wherein the at least one object to be sensed comprises a plurality of objects to be sensed arranged so as to be spaced apart from each other in a direction in which the guide rail extends.

9 . The air-conditioning system according to claim 1 , wherein the first air-processing apparatus further comprises a heat exchanger configured to cause air introduced into the first inlet to exchange heat with the refrigerant, and wherein the second air-processing apparatus further comprises a filter device configured to remove foreign substances from air introduced into the second inlet.

10 . The air-conditioning system according to claim 1 , wherein the first air-processing apparatus further comprises:
a first case that forms an external appearance of the first air-processing apparatus; a first housing disposed inside of the first case, the first housing forming a flow path through which air flows; and a first fan disposed inside of the first housing, the first fan being configured to cause air to flow, wherein the first case comprises:
a first upper cover configured to be fixed to a ceiling;
a first lower cover disposed below the first upper cover;
a first rear cover having formed therein the first inlet, the first rear cover supporting a first pre-filter mounted thereto;
a first front cover disposed so as to be spaced forwards apart from the first rear cover; and
a pair of first side covers disposed at respective ends of the first lower cover, and wherein a lower end of the first front cover is disposed so as to be spaced apart from a front end of the first lower cover to form the first outlet.

11 . The air-conditioning system according to claim 10 , wherein the first air-processing apparatus further comprises:
a first louver rotatably disposed in the first case to adjust a direction of air that is discharged through the first outlet; and a first louver actuator configured to change an orientation of the first louver, wherein the first louver is rotatably disposed at a lower side of the first front cover, and wherein the first louver actuator is disposed at an upper side of the first lower cover.
