Abstract

The air conditioner apparatus according to the present invention includes: a case which forms a first common passage, and a second common passage; and a suction guide which is disposed in each of the first common passage and the second common passage, which guides air flown into the case to a first desiccant heat exchanger which is disposed in the first common passage or a second desiccant heat exchanger which is disposed in the second common passage, and which forms a compressor accommodation chamber where a compressor is accommodated, wherein at least two cooling holes for sending some of the air flown into the case to the compressor accommodation chamber and for sending air flowing inside the compressor accommodation chamber to the first common passage or the second common passage are formed in the suction guide.

First claim

The invention claimed is:

1. An air conditioner apparatus comprising:
a case which forms a first common passage, through which indoor air or outdoor air flows, and a second common passage, through which indoor air or outdoor air flows and which is positioned above the first common passage;
an indoor discharge fan which directs outdoor air to flow into an indoor space through the first common passage or the second common passage;
an outdoor discharge fan which directs indoor air to flow into an outdoor space through the first common passage or the second common passage;
a first desiccant heat exchanger which is disposed in the first common passage to humidify or dehumidify air flowing in the first common passage;
a second desiccant heat exchanger which is disposed in the second common passage to humidify or dehumidify air flowing in the second common passage;
a compressor that compresses a refrigerant flowing into the first desiccant heat exchanger or the second heat exchanger;
a suction guide which is disposed in each of the first common passage and the second common passage, which guides air flowing into the case to the first desiccant heat exchanger or the second desiccant heat exchanger, and which forms a compressor accommodation chamber in which the compressor is accommodated; and
a control box which accommodates a control device, and which is disposed external to the case, wherein at least two cooling holes through which some of the air flowing into the case flows to the compressor accommodation chamber and through which air flowing inside of the compressor accommodation chamber flows to the first common passage or the second common passage are formed in the suction guide, wherein an inside of the case is provided with:
an indoor discharge chamber which is connected to the first common passage and the second common passage and through which air is discharged to the indoor space; and
an outdoor discharge chamber which is connected to the first common passage and the second common passage and through which air is discharged to the outdoor space, wherein the indoor discharge fan is disposed in the indoor discharge chamber, and the outdoor discharge fan is disposed in the outdoor discharge chamber, wherein a communication hole is formed in one surface of the case, onto which the control box is disposed, so that air flowing inside the case flows into the control box, wherein the control box is disposed external to the case in which the compressor accommodation chamber is formed, and wherein the communication hole provides communication between the compressor accommodation chamber and an inside of the control box.

2. The air conditioner apparatus of claim 1 , wherein an inside of the case is further provided with:
an indoor suction chamber which is connected to the first common passage and the second common passage, and into which indoor air is suctioned; and
an outdoor suction chamber which is connected to the first common passage and the second common passage, and into which outdoor air is suctioned, and wherein the suction guide comprises:
a first guide surface which guides air suctioned into the indoor suction chamber, and in which a first cooling hole through which some of the air flows to the compressor accommodation chamber is formed; and
a second guide surface which guides air suctioned into the outdoor suction chamber, and in which a second cooling hole through which some of the air flows to the compressor accommodation chamber is formed.

3. The air conditioner apparatus of claim 1 , wherein a discharge hole through which air flowing into the compressor accommodation chamber flows to the first desiccant heat exchanger or the second desiccant heat exchanger is formed in the suction guide.

4. The air conditioner apparatus of claim 1 , further comprising one-way valves which are disposed at the at least two cooling holes of the suction guide to control a flow direction of air communicating through the at least two cooling holes to be a one-way direction.

5. The air conditioner apparatus of claim 1 , wherein an inside of the case is further provided with:
an indoor suction chamber which is connected to the first common passage and the second common passage, and into which indoor air is suctioned; and
an outdoor suction chamber which is connected to the first common passage and the second common passage, and into which outdoor air is suctioned, and wherein the suction guide comprises:
a first guide surface which guides air suctioned into the indoor suction chamber, and in which a first cooling hole through which some of the air flows to the compressor accommodation chamber is formed;
a second guide surface which guides air suctioned into the outdoor suction chamber and in which a second cooling hole through which some of the air flows to the compressor accommodation chamber is formed; and
a central guide surface which connects the first guide surface and the second guide surface, and in which a discharge hole through which air flowing into the compressor accommodation chamber flows to the desiccant heat exchangers is formed.

6. The air conditioner apparatus of claim 5 , wherein a first one-way valve that controls air flowing through the first cooling hole to flow in a one-way direction is disposed in the first guide surface, and wherein a second one-way valve that controls air flowing through the second common passage to flow in a one-way direction is disposed in the second guide surface.

7. The air conditioner apparatus of claim 6 , wherein the first one-way valve and the second one-way valve rotate inwardly toward the compressor accommodation chamber.

8. An air conditioner apparatus comprising:
a case which forms a first common passage, through which indoor air or outdoor air flows, and a second common passage, through which indoor air or outdoor air flows and which is positioned above the first common passage;
an indoor discharge fan which directs outdoor air to flow into an indoor space through the first common passage or the second common passage;
an outdoor discharge fan which directs indoor air to flow into an outdoor space through the first common passage or the second common passage;
a first desiccant heat exchanger which is disposed in the first common passage to humidify or dehumidify air flowing in the first common passage;
a second desiccant heat exchanger which is disposed in the second common passage to humidify or dehumidify air flowing in the second common passage;
a compressor that compresses a refrigerant flowing into the first desiccant heat exchanger or the second heat exchanger;
a suction guide which is disposed in each of the first common passage and the second common passage, which guides air flowing into the case to the first desiccant heat exchanger or the second desiccant heat exchanger, and which forms a compressor accommodation chamber in which the compressor is accommodated, wherein at least two cooling holes through which some of the air flowing into the case flows to the compressor accommodation chamber and through which air flowing inside of the compressor accommodation chamber flows to the first common passage or the second common passage are formed in the suction guide; and
one-way valves which are disposed at the at least two cooling holes of the suction guide to control a flow direction of air communicating through the at least two cooling holes to be a one-way direction, wherein an inside of the case is provided with:
an indoor discharge chamber which is connected to the first common passage and the second common passage and through which air is discharged to the indoor space; and
an outdoor discharge chamber which is connected to the first common passage and the second common passage and t
