Hereinafter, embodiments of the present invention will be described in detail with reference to the following drawings.
A housing 10 includes a left panel 11a and a right panel 11b which form left and right sides, a front panel 12, a rear panel 13, a top panel 14, and a bottom panel 15.
The housing 10 may include an intake port through which air inflows from the outside and an exhaust port through which the internal air is discharged.
The housing 10 may include a first housing 30 on an upper side thereof and a second housing 70 at a lower side, and a partition 100 may be provided between the first housing 30 and the second housing 70 to prevent an air flow between the first housing 30 and the second housing 70.
The first housing 30 may serve as an indoor unit of a cooler in a split-type air conditioner and include an evaporator 26 and a first blower fan 40. The second housing 70 may serve as an outdoor unit of the cooler in the split-type air conditioner and include a condenser 22 and a second blower fan 90. However, the present invention is not limited thereto, and the first housing 30 may also serve as an outdoor unit of a heater and the second housing 70 may also serve as an indoor unit of the heater.
A first intake port 32 through which air inflows from the outside and a first exhaust port 34 through which the internal air is discharged are provided in the first housing 30, and a second intake port 72 through which air inflows from the outside and a second exhaust port 74 through which the internal air is discharged are provided in the second housing 70.
In the embodiment of the present invention, even though the first intake port 32 and the second intake port 72 are vertically provided in the left panel 11a, the arrangement may also be different from the above description according to an internal arrangement of components.
In the embodiment of the present invention, even though the first exhaust port 34 and the second exhaust port 74 are respectively provided at the front panel 12 and the right panel 11b, the arrangement may also be different from the above description according to an internal arrangement of components.
The compressor 20 compresses a refrigerant to have a high temperature and a high pressure and discharges the refrigerant, and the compressed refrigerant flows into the condenser 22. The condenser 22 condenses the refrigerant compressed by the compressor 20 into a liquid state. Heat is emitted to the outside through a condensing process.
An expansion unit 24 expands the liquid refrigerant having a high temperature and high pressure, which is condensed in the condenser 22, to become a liquid refrigerant in a low pressure state, and the evaporator 26 achieves a refrigeration effect by evaporating the refrigerant expanded by the expansion unit 24 and performing a heat exchange with an object to be cooled using the latent heat from the evaporation of the refrigerant and performs a function of returning the refrigerant having a low temperature and low pressure to the compressor 20. An air temperature of an indoor space may be adjusted using such a cycle.
A blower fan may include the first blower fan 40 provided on a first fluid channel 37 of the first housing 30 and the second blower fan 90 provided on a second fluid channel 76 of the second housing 70.
In the embodiment of the present invention, since the first intake port 32 and the first exhaust port 34 are disposed perpendicular to each other, a centrifugal fan may be used for the first blower fan 40. Accordingly, the temperature of air introduced from the outside through the first intake port 32 formed in the left panel 11a may decrease while flowing through the evaporator 26, and the air may be discharged to the first exhaust port 34 formed in the front panel 12 through the first blower fan 40. The air discharged by the first blower fan 40 may be guided by a first blower fan guide 42 which surrounds the first blower fan 40 and may be discharged through the first exhaust port 34. The first blower fan 40 may be operated by a first motor 44 provided on a rotation shaft.
At least one blade 35 for guiding the discharged internal air may be provided in the first exhaust port 34.
In the embodiment of the present invention, since the second intake port 72 and the second exhaust port 74 are disposed to face each other, an axial fan may be used for the second blower fan 90. Accordingly, the temperature of air which inflows from the outside through the second intake port 72 formed in the left panel 11a may increase while the air flows through the condenser 22, and the air may be discharged through the second exhaust port 74 formed in the right panel 11b using the second blower fan 90. The air discharged by the second blower fan 90 may be guided by a bell mouth 92 which surrounds the second blower fan 90 and may be discharged through the second exhaust port 74. The second blower fan 90 may be operated by a second motor 96 provided on a rotation axis. Since a fan guard 94 is provided at an outside of the bell mouth 92, the fan guard 94 protects the second blower fan 90 and guides the air discharged by the second blower fan 90 to the outside.
In the embodiment of the present invention, even though the centrifugal fan and the axial fan are used for the blower fan, the first blower fan 40 and second blower fan 90 may be different types of fans according to directions of the exhaust ports. For example, the first exhaust port 34 may be provided in the right panel 11b and the first blower fan 40 may also include the axial fan. In addition, the second exhaust port 74 may be provided in the front panel 12, and the second blower fan 90 may also include the centrifugal fan.
The partition 100 which partitions the first housing 30 and the second housing 70 may be provided therebetween. The partition 100 may be provided to seal a lower portion of the first housing 30 and an upper portion of the second housing 70 so that internal air does not flow between the first housing 30 and the second housing 70.
A seating portion 102 formed to protrude toward the second housing 70 may be provided on the partition 100 so that the first blower fan 40 in the first housing 30 is seated. The seating portion 102 may be convexly formed on the first housing 30 and may be concavely formed on the second housing 70. Since the height of the first blower fan 40 in the first housing 30 may be decreased using the above-described configuration, the entire height of the integrated air conditioner 1 may be decreased.
The seating portion 102 may include a convex portion 102a whose outside surface is convexly formed with respect to a bottom surface of the partition 100 and a concave portion 102b in which a rear surface of the convex portion 102a is concavely formed with respect to a top surface of the partition 100. Since the first blower fan 40 is seated on the concave portion 102b and the second blower fan 90 is provided on a side surface of the convex portion 102a, the first blower fan 40 and the second blower fan 90 are not vertically disposed. Using the above-described structure, even when the fan blade of the blower fan is large, the first blower fan 40 and the second blower fan 90 do not interfere with each other, and thus the integrated air conditioner 1 may be miniaturized.
That is, when an imaginary surface including a rear surface of the first blower fan 40 refers to a first reference surface P1, a front surface of the second blower fan 90 may be disposed at the same surface of the first reference surface P1 or disposed at a rear portion thereof. On the contrary, when an imaginary surface including the front surface of the second blower fan 90 refers to a second reference surface P2, the rear surface of the first blower fan 40 may be disposed at the same surface of the second reference surface P2 or disposed at a front portion thereof. In addition, the first blower fan 40 and the second blower fan 90 may be provided so that the first reference surface P1 is disposed at a rear portion of the second reference surface P2.
Even though the compressor 20 may be provided in the housing 10, in the embodiment of the present invention, the compressor 20 is provided on the second fluid channel 76. Specifically, the compressor 20 is provided between the condenser 22 and the second blower fan 90 on the second fluid channel 76, and thus, heat generated by the compressor 20 may be decreased by the second blower fan 90.
The expansion unit 24 which may be disposed between the condenser 22 and the evaporator 26 as described above may perform a function of expanding a liquid refrigerant having a high temperature and high pressure, which is condensed by the condenser 22, to become a liquid refrigerant in a low pressure state and may be formed to have a capillary tube in the embodiment of the present invention. In addition, the expansion unit 24 may be formed to pass the first housing 30 and the second housing 70.
The second fluid channel 76 which is a fluid channel of air which flows through the second housing 70 is provided between the second intake port 72 and the second exhaust port 74, and the condenser 22 is provided on the second fluid channel 76. Specifically, the condenser 22 may be provided on the second fluid channel 76 to be adjacent to the second intake port 72.
The first fluid channel 37 which is fluid channel of air which flows through the first housing 30 is provided between the first intake port 32 and the first exhaust port 34, and the evaporator 26 is provided on the first fluid channel 37. Specifically, the evaporator 26 may be provided on the first fluid channel 37 to be adjacent to the first intake port 32.
Since the first intake port 32 and the second intake port 72 may be provided to respectively correspond the evaporator 26 and the condenser 22 and the evaporator 26 and the condenser 22 are disposed adjacent to the left panel 11a in the embodiment of the present invention, the first intake port 32 and the second intake port 72 may also be provided on the left panel 11a. However, the present invention is not limited thereto, and when the evaporator 26 and the condenser 22 extend along and are formed adjacent to another surface, the first intake port 32 and the second intake port 72 may also be formed on another surface corresponding to the evaporator 26 and the condenser 22.
At least parts of the evaporator 26 and the condenser 22 may be provided to be vertically disposed.
Condensate is generated on a surface of the evaporator 26 while indoor air exchanges heat with the evaporator 26. The generated condensate may be dropped onto a surface of the condenser 22 to improve an efficiency of heat exchange of the condenser 22, and simultaneously, the condensate generated by the evaporator 26 may not be discharged additionally.
A water storage tray 50 is provided under the evaporator 26 to collect the condensate and spray the condensate to the condenser 22.
The water storage tray 50 may include an opening facing the evaporator 26, a tray bottom surface 52 corresponding to a heat exchanger, and a tray flange 54 formed to extend upward from an end of the tray bottom surface 52.
Drain holes are provided in the tray bottom surface 52 to correspond to a layout of an upper portion of the condenser 22. Since the condensate wets the surface of the condenser 22 by being drained through the drain holes while being stored in the water storage tray 50, the efficiency of heat exchange of the condenser 22 may be improved.
At least a part of the tray bottom surface 52 includes an inclined surface, and the tray bottom surface 52 includes a first portion 53a which is a lower end of one side of the inclined surface and a second portion 53b which is disposed higher than the first portion 53a and an upper end of one side of the inclined surface. The drain holes 55 may be disposed in the first portion 53a. Condensate may flow along the inclined surface and not stay and thus may be discharged through the drain holes 55 using the above-described configuration.
The tray bottom surface 52 may be formed parallel to the evaporator 26 disposed thereon, and one or more drain holes 55 may be provided in the tray bottom surface 52 to be parallel to a layout of the condenser 22.
A drain tray 98 is provided under the condenser 22 to store the remaining condensate after the condensate is discharged from the water storage tray 50 and decreased at the surface of the condenser 22.
Hereinafter, an operation of the integrated air conditioner including the above-described configuration according to one embodiment of the present invention will be described in detail.
When the air conditioner 1 operates, a refrigerant moves through a compressor 20, a condenser 22, an expansion unit 24, and an evaporator 26.
In the above-described process, a condensate is generated on the surface of the evaporator 26 due to the external air passing through. The condensate is stored in the water storage tray 50, drained through the drain hole 55, and evaporated from the surface of the condenser 22, thereby improving the efficiency of the heat exchange of the condenser 22.
From an air conditioning perspective, since the evaporator 26 and the condenser 22 are vertically disposed on one side surface of the housing 10 of the air conditioner 1, the first intake port 32 which guides external air to the evaporator 26 and the second intake port 72 which guides the external air to the condenser 22 are provided on the same side in the housing 10.
Internal air, which passed through the evaporator 26 and thus had a lower temperature than an external air, is discharged to the first exhaust port 34 of the front panel 12 through the first blower fan 40, and internal air, which passed through the condenser 22 and thus had a higher temperature than an external air, is discharged to the second exhaust port 74 of the right panel 11b through the second blower fan 90.
Since the first exhaust port 34 and the second exhaust port 74 are provided separately and laterally and provided at different sides of the housing, a cooling influence due to an interference with each other may be decreased, and thus, cooling efficiency or heating efficiency may be improved.
In another embodiment of the present invention, the same configuration as that described with one embodiment of the present invention or a repeating configuration will be omitted.
In another embodiment of the present invention, a condenser 22 may be provided on two sides of a second housing 70. Even though the condenser 22 is provided on the two sides in the present embodiment, on the contrary, an evaporator 26 may be formed as in the present embodiment, and the two components may also be formed as in the present embodiment.
As the condenser 22 is provided on the two sides, a second intake port 82 may also be provided on two sides in the second housing 70 along the condenser 22. A second fluid channel 86 which connects the second intake port 82 and a second exhaust port 84 is formed on the second intake port 82 and the second exhaust port 84.
A water storage tray 60 may include an opening facing the evaporator 26, a tray bottom surface 62 corresponding to a heat exchanger, and a tray flange 64 formed to extend upward from an end of the tray bottom surface 62.
A drain hole 65 is provided in the tray bottom surface 62 to correspond to a shape of an upper portion of the condenser 22. Since condensate wets a surface of the condenser 22 by being drained through the drain hole 65 while being stored in the water storage tray 60, the efficiency of heat exchange of the condenser 22 may be improved.
At least a part of the tray bottom surface 62 includes an inclined surface, and the tray bottom surface 62 includes a first portion 63a which is a lower end of one side of the inclined surface, and a second portion 63b which is disposed at a higher level than the first portion 63a and an upper end of one side of the inclined surface. The drain hole 65 may be disposed in the first portion 63a. Condensate may flow along the inclined surface and not stay and may be discharged through the drain hole 65 using the above-described structure.
The water storage tray 60 includes a first water storage region 68a provided to correspond to a lower portion of the evaporator 26 and a second water storage region 68b provided to correspond to an upper portion of the condenser 22.
Since at least parts of the evaporator 26 and the condenser 22 are provided to be matched vertically, at least a part of the first water storage region 68a may overlap the second water storage region 68b.
The drain hole 65 is provided in the tray bottom surface 62 of the second water storage region 68b to discharge condensate along a layout of the condenser 22.
Hereinafter, an operation of the integrated air conditioner 1 including the above-described configuration according to another embodiment of the present invention will be described.
When the air conditioner 1 operates, a refrigerant moves through the compressor 20, the condenser 22, the expansion unit 24, and the evaporator 26.
In this process, a condensate is generated on a surface of the evaporator 26 due to external air passing through the evaporator 26. The condensate is stored in the water storage tray 60, and specifically, is stored in the first water storage region 68a. Since at least a part of the first water storage region 68a overlaps the second water storage region 68b, the condensate is stored in the first water storage region 68a and the second water storage region 68b in equal amounts.
The stored condensate is discharged to an upper portion of the condenser 22 through the drain hole 65 provided in the second water storage region 68b, thereby improving the efficiency of heat exchange of the condenser 22.
In the above, specific embodiments of the present invention are illustrated and described. However, the present invention is not limited to the embodiments described above, and it will be understood by those skilled in the art that various modifications and alternations may be made without departing from the spirit and scope described in the appended claims.
