Abstract

The present invention relates to a dehumidifying and cooling apparatus, comprising: a housing in which a first channel and a second channel are formed; a heating unit disposed inside the first channel; a desiccant rotor which is rotatably provided inside the housing; a cooling unit disposed inside the second channel; and a refrigerant circulation unit having a refrigerant circulation circuit including a compressor and a condenser, wherein the condenser is disposed inside the second channel such that the refrigerant circulated therein, can be condensed by the heat exchange with the second air cooled by the cooling unit.

First claim

The invention claimed is:

1. A dehumidifying and cooling apparatus comprising:
a housing having first and second channels formed therein, first air passing through the first channel, second air passing through the second channel;
a heater disposed in the first channel to heat the first air;
a desiccant rotor rotatably installed in the housing such that the desiccant rotor is dried by the first air heated by the heater and absorbs moisture from the second air;
a cooler disposed in the second channel to cool the second air having passed through the desiccant rotor; and
a refrigerant circulation circuit including a compressor and a condenser,
wherein the condenser is disposed in the second channel so that a refrigerant circulating in the condenser is condensed by heat exchange with the second air cooled by the cooler,
wherein a portion of the second air cooled by the cooler is discharged to an outdoor space after heat exchange in the condenser, while a remainder of the second air cooled by the cooler is supplied to an indoor space.

2. The dehumidifying and cooling apparatus of claim 1 , wherein the first air is air introduced into the first channel from the outdoor space, and the first air passing through the first channel is discharged to the outdoor space.

3. The dehumidifying and cooling apparatus of claim 1 , wherein:
the second air is air introduced into the second channel from the outdoor space.

4. The dehumidifying and cooling apparatus of claim 1 , further comprising:
a first blower disposed in the first channel such that the first air forcibly passes through the first channel; and
a second blower disposed in the second channel such that the second air forcibly passes through the second channel.

5. The dehumidifying and cooling apparatus of claim 4 , wherein each of the first and second blowers is selectively operated or stopped by a controller.

6. The dehumidifying and cooling apparatus of claim 1 , wherein:
the refrigerant circulation circuit further comprises an evaporator; and
the dehumidifying and cooling apparatus further comprises a cold water circulation pipe connected to the evaporator such that water circulating in the cold water circulation pipe exchanges heat with the refrigerant circulating in the evaporator.

7. The dehumidifying and cooling apparatus of claim 6 , wherein at least a portion of the cold water circulation pipe is disposed within at least one of an interior floor, an interior ceiling, and an interior wall, or is disposed in a fan coil assembly.

8. The dehumidifying and cooling apparatus of claim 1 , wherein:
the refrigerant circulation circuit further comprises an evaporator; and
the dehumidifying and cooling apparatus further comprises a blower fan for forcibly blowing indoor air, such that the indoor air exchanges heat with the refrigerant circulating in the evaporator and is then supplied back to the indoor space.

9. The dehumidifying and cooling apparatus of claim 1 , further comprising a water supply assembly disposed in the second channel so as to spray water on a surface of the condenser.

10. A dehumidifying and cooling apparatus comprising:
a housing having first, second, and third channels formed therein, first air passing through the first channel, second air passing through the second channel, third air passing through the third channel;
a heater disposed in the first channel to heat the first air;
a desiccant rotor rotatably installed in the housing such that the desiccant rotor is dried by the first air heated by the heater and absorbs moisture from the second air and the third air;
first and second coolers disposed in the respective second and third channels so as to respectively cool the second air and the third air having passed through the desiccant rotor; and
a refrigerant circulation circuit comprising a compressor and a condenser, wherein:
the condenser is disposed in the second channel so that a refrigerant circulating in the condenser is condensed by heat exchange with the second air cooled by the first cooler; and
the third air is one of air introduced from an indoor space, a mixture of air introduced from the indoor space and air introduced from an outdoor space, and air introduced from the outdoor space, and the third air is cooled by the second cooler and is then discharged to the indoor space,
wherein a portion of the second air cooled by the cooler is discharged to an outdoor space after heat exchange in the condenser, while a remainder of the second air cooled by the cooler is supplied to an indoor space.

11. The dehumidifying and cooling apparatus of claim 10 , wherein the first air is air introduced from the outdoor space or air introduced from the indoor space, and the first air is discharged to the outdoor space after passing through the desiccant rotor.

12. The dehumidifying and cooling apparatus of claim 10 , wherein:
the second air is air introduced from the outdoor space or a mixture of air introduced from the indoor space and air introduced from the outdoor space.

13. The dehumidifying and cooling apparatus of claim 10 , further comprising:
a first blower disposed in the first channel such that the first air forcibly passes through the first channel;
a second blower disposed in the second channel such that the second air forcibly passes through the second channel; and
a third blower disposed in the third channel such that the third air forcibly passes through the third channel.

14. The dehumidifying and cooling apparatus of claim 13 , wherein each of the first, second, and third blowers is selectively operated or stopped by a controller.

15. The dehumidifying and cooling apparatus of claim 10 , further comprising an air filter disposed in the third channel.

16. The dehumidifying and cooling apparatus of claim 10 , wherein:
the refrigerant circulation circuit further comprises an evaporator; and
the dehumidifying and cooling apparatus further comprises a cold water circulation pipe connected to the evaporator such that water circulating in the cold water circulation pipe exchanges heat with the refrigerant circulating in the evaporator.

17. The dehumidifying and cooling apparatus of claim 16 , wherein a portion of the cold water circulation pipe is disposed within at least one of an interior floor, an interior ceiling, and an interior wall, or is disposed in a fan coil assembly.

18. The dehumidifying and cooling apparatus of claim 10 , wherein:
the refrigerant circulation circuit further comprises an evaporator; and
the dehumidifying and cooling apparatus further comprises a blower fan for forcibly blowing indoor air, such that the indoor air exchanges heat with the refrigerant circulating in the evaporator and is then supplied back to the indoor space.

19. The dehumidifying and cooling apparatus of claim 10 , further comprising a water supply assembly disposed in the second channel so as to spray water on a surface of the condenser.
