<First Embodiment>

1 is a perspective view showing a schematic configuration of an air conditioner according to a first embodiment of the present invention.

Referring to FIG. 1, the air conditioner according to the embodiment of the present invention may be mounted indoors, and in particular, may be installed in a high humidity space such as a bathroom to obtain a high dehumidifying effect. In other words, the air conditioner may be a hybrid air conditioner that allows the dehumidification function to be selectively performed according to the indoor humidity in the cooling or heating process.

In detail, the air conditioner 10 includes a case 11 forming an appearance, a partition wall 16 dividing the inside of the case 11, and an inner rear side of the case 11 to provide indoor air. A blowing fan 12 for sucking, a refrigerant circulation cycle for cooling or heating the sucked indoor air, and a dehumidifying unit for dehumidifying the sucked indoor air are included.

More specifically, the refrigerant circulation cycle includes a compressor 13 for compressing a refrigerant, a condenser 14 for condensing the compressed refrigerant, an expansion valve P for expanding the condensed refrigerant, and an evaporator for evaporating the expanded refrigerant. (15) is included. Since the refrigerant circulation cycle has the same configuration as the refrigerant circulation cycle of the general air conditioner, the signature of the functions of these configurations will be omitted.

In addition, the dehumidification unit includes a desiccant 17 that performs a dehumidification function, and a regeneration unit 20 provided above and below the desiccant 17 to regenerate the desiccant 17. . The regeneration unit 20 includes a regeneration suction duct 21 through which a part of the air passing through the condenser 14 is sucked, and a regeneration exhaust duct 23 through which a high humidity air is discharged through the regeneration process. And other structures. Detailed structure of the regeneration unit 20 will be described below in detail with reference to the accompanying drawings.

On the other hand, the inlet 111 for suctioning the indoor air is formed on the bottom surface of the case 11, in particular the bottom surface of the point where the blowing fan 12 is located. The case 11 is divided into a heating space through which hot air flows and a cooling space through which low temperature air flows by the partition wall 16.

In addition, the front bottom surface of the case 11 is provided with a discharge port for discharging the sucked indoor air, the discharge hole is formed in the first discharge port 112 formed on the bottom surface of the heating space and the bottom surface of the cooling space A second discharge port 113 is formed. In addition, an exhaust port is formed on the front surface of the case 11 to exhaust the sucked air to the outside, and the exhaust port has an exhaust port 114 formed on the front surface of the heating space and an end portion of the regenerative exhaust duct 23. Regeneration exhaust port 115 is connected to the.

In addition, a sealing member is provided around the inner wall of the case 11 and the parts so that all of the air sucked by the blower fan 12 passes through the condenser 14 or the evaporator 15 and the dehumidification unit. do. Reference numerals 40 and 41 are dampers, which will be described later.

By the above configuration, the indoor air sucked by the blower fan 12 is heated, cooled or dehumidified while passing through at least one of the condenser 14 or the evaporator 15 and the dehumidification unit and discharged back to the room. Or exhausted outdoors. The indoor air flow structure will be described in more detail below with reference to the accompanying drawings.

FIG. 2 is a cross-sectional view taken along the line II ′ of FIG. 1.

2, the case 18 of the air conditioner 10 according to the embodiment of the present invention is partitioned into a heating space and a cooling space by the partition wall 16. The condenser 14 is disposed in the heating space, and the evaporator 15 is disposed in the cooling space. In addition, both side surfaces of the condenser 14 and the evaporator 15 are surrounded by a sealing member 18 for preventing air leakage. When the sealing member 18 is absent, a phenomenon may occur in which indoor air sucked through the blower fan 12 is discharged to the room as it is without passing through the condenser 14 or the evaporator 15.

Although the drawings are shown to surround only the side of the condenser 14 and the evaporator 15, the present invention is not limited thereto, and the condenser 14 and the evaporator 15 may be surrounded by the entire condenser 14 so that the sucked air does not leak. This may be appropriately designed according to the structure inside the air conditioner 10.

3 is a cross-sectional view taken along line II-II 'of FIG. 1, and FIG. 4 is a plan view of a dehumidifying unit according to an exemplary embodiment of the present invention.

3 and 4, a dehumidification unit is provided in the case 11 of the air conditioner 10 according to the embodiment of the present invention, specifically, in a cooling space, to control the humidity of the air to be sucked. .

In detail, the dehumidification unit includes a desiccant 17 which absorbs moisture and a regeneration unit 20 which reproduces the desiccant 17.

In more detail, the regeneration unit 20 includes a regeneration suction duct 21 into which high-temperature air passing through the condenser 14 is introduced, and a lower container 22 formed at an end of the regeneration suction duct 21. And an upper container 24 through which the air absorbing moisture collected in the desiccant 17 collects while penetrating the desiccant 17, and the air moved to the upper container 24 is discharged to the outside. A regenerative exhaust duct 23 and a heater 25 provided inside the lower container 22 to heat the sucked air are included. Here, the regeneration suction duct 21 and the lower container 22 are called regeneration suction portions, and the regeneration exhaust duct 23 and the upper container 24 are called regeneration exhaust portions.

The regeneration suction duct 21 and the regeneration exhaust duct 23 pass through the partition wall 16 and are placed in the heating space. The regenerative suction duct 21 and the regenerative exhaust duct 23 are disposed symmetrically on the upper and lower surfaces of the desiccant 17, respectively.

In addition, the end of the regeneration suction duct 21 is bent toward the room air inflow, the end of the regeneration exhaust duct 22 is bent in the opposite direction to communicate with the outdoors. Then, the indoor air to be sucked is introduced into the regeneration unit 20 by natural flow and then discharged to the outside.

In detail, when air is introduced into the case 11 by the blowing fan 12, the inside of the case, that is, the inlet portion of the regeneration suction duct 21 becomes a high pressure higher than atmospheric pressure. The end portion of the regenerative exhaust duct 23 communicates with the outdoors, and thus is at atmospheric pressure. Therefore, by the flow characteristics flowing from high pressure to low pressure, the regeneration function is smoothly performed even if no separate regeneration blower fan is mounted. In addition, since hot air passing through the condenser 14 flows into the regeneration unit 20, energy required for preheating the air required for regeneration is saved. As a result, energy is saved, and at the same time, the structure of the product is simplified, thereby reducing the manufacturing cost.

In addition, the lower container 22 and the upper container 24 are formed to have a size covering a portion of the upper and lower surfaces of the desiccant 17. Therefore, the indoor air sucked by the operation of the blower fan 12 is dehumidified while penetrating the desiccant 17 surface excluding the upper container 24 area. Then, the desiccant 17 rotates to pass through the upper container 24 portion, and in this process, a regeneration process in which moisture permeating the desiccant 17 evaporates is performed.

On the other hand, the rotating shaft 171 is extended to the center of the desiccant 17 is rotatably fixed to the bottom surface of the case (11). In addition, a sealing member 18 is provided between the outer circumferential surface of the desiccant 17 and the case 11 to block a part of the sucked air from leaking without passing through the desiccant 17.

FIG. 5 is a cross-sectional view taken along line III-III ′ of FIG. 1.

Referring to FIG. 5, a blowing fan 12, an evaporator 15, and a dehumidifying unit are sequentially disposed from the rear side in the cooling space inside the case 11.

In detail, the evaporator 15 and the desiccant 17 are mounted inside the case 11 in an inclined angle from a vertical plane. As shown, the evaporator 15 and the desiccant 17 are mounted at an angle inclined, so that the evaporator 15 and the desiccant 17 having a larger capacity can be mounted.

More specifically, the bottom of the evaporator 15 is provided with a drain pan 19 for collecting condensate. In addition, a second damper 41 is mounted on the second discharge port 113 to selectively open and close the second discharge port 113. In addition, a deodorization filter 50 may be installed in the second discharge port 113 to purify the air discharged into the room.

On the other hand, the rotary shaft 171 of the desiccant 17 is rotatably fixed to the bottom surface of the case (11). Of course, the rotating shaft 171 will be fixed to be inclined. In addition, a driving body for rotating the desiccant 17 at a predetermined speed is provided. The driving body 30 includes a driving gear that rotates in engagement with an outer circumferential surface of the desiccant 17, and the driving gear 31. The motor 32 is rotated. As shown, since the desiccant 17 is mounted obliquely, the driving body 30 should also be mounted obliquely on the bottom surface of the case 11. Here, the means for rotating the desiccant 17 is not limited to the driving gear structure, and the driving motor may be directly connected to the rotating shaft 171. That is, the driving means and mounting structure for rotating the desiccant 17 will not be limited to the embodiment presented in the present invention.

The evaporator 15, the desiccant 17, and the driving body 30 are surrounded by the sealing member 18 for the same reason as described above.

FIG. 6 is a cross-sectional view taken along line IV-IV ′ of FIG. 1.

Referring to FIG. 6, the regenerative suction duct 21 and the regenerative exhaust duct 23 penetrate the partition wall 16 to be disposed in a heating space, and end portions thereof are bent in opposite directions.

In detail, a first discharge port 112 is formed on the bottom surface of the heating space so as to be sucked by the blower fan 12 and discharge the heated air to the room while passing through the condenser 14. In addition, an exhaust port 114 for discharging the heated air to the outside is formed in front of the heating space. In addition, a first damper 40 may be installed at the front lower edge of the case 11 to selectively shield the first discharge port 112 and the exhaust port 114. In addition, the first discharge port 112 may be provided with a deodorization filter 50 to purify the air discharged into the room.

7 is a bottom perspective view showing a state in which the air conditioner according to an embodiment of the present invention is mounted indoors, and FIG. 8 is a plan perspective view showing the state in which the air conditioner is mounted indoors.

7 and 8, the air conditioner 10 according to the embodiment of the present invention has a structure mounted on the indoor ceiling.

In detail, the bottom surface of the air conditioner 10 faces the indoor floor, and the indoor air is sucked through the inlet 111, and cold air or warm air is flown through the first outlet 112 and the second outlet 113. Allow air to be discharged into the room. An exhaust duct connected to the exhaust port 114 and the regeneration exhaust duct 23 is formed on the wall surface. In addition, when the exhaust port is formed in the front surface of the cooling space of the air conditioner 10, an exhaust duct corresponding thereto may be further formed on the wall surface.

In addition, a humidity sensor 70 for detecting indoor humidity is mounted near the suction port 111, and according to the detected humidity, whether the dehumidification unit is operated and the operation state of the dampers 40 and 41 are automatically controlled. You can do that. Here, the mounting position of the humidity sensor 70 is not limited to the embodiment presented, of course, may be mounted on one side or one side of the bottom surface of the air conditioner (10).

9 is a view showing the air flow when the heating process is performed in the air conditioner according to the first embodiment of the present invention.

Referring to FIG. 9, when the user selects the heating mode, the first damper 40 is operated to open the first discharge port 112 and shield the exhaust port 114. In addition, the second damper 40 is operated to maintain the second discharge port 113 in an open state.

In addition, as the blower fan 12 rotates, the refrigerant circulation cycle operates to perform compression, condensation, expansion, and evaporation processes. Then, the dehumidification unit is operated so that the desiccant 17 rotates at a predetermined speed.

In detail, when the blowing fan 12 rotates, indoor air is sucked through the suction port 111, and a part of the sucked air moves to the heating space, and the other part moves to the cooling space. The air moving to the heating space rises in temperature while passing through the condenser 14. The air moving to the cooling space passes through the evaporator 15, and at the same time the temperature decreases, moisture contained in the air is condensed and collected in the drain pan 19. Therefore, the air passing through the evaporator 15 is condensed while the absolute humidity drops.

On the other hand, most of the air passing through the condenser 914 is discharged back to the room through the first discharge port 112, a part is sucked into the regeneration suction duct (21). The air moving along the regeneration suction duct 21 is heated again by the heater 25 in the lower container 22. The heated air passes through the desiccant 17 and moves to the upper container 24. The air collected in the upper container 24 is discharged to the outside through the regenerative exhaust duct 23.

In addition, the air condensed while passing through the evaporator 15 is subjected to a dehumidification process while passing through the desiccant 17. That is, dehumidification occurs while passing through the desiccant 17, and the air that has undergone the dehumidification process is discharged back into the room through the second discharge port 113.

Here, the air discharged to the first discharge port 112 is increased in temperature than when sucked through the inlet 111 while passing through the condenser 14. On the other hand, the air passing through the second discharge port 113 is lower than the temperature when the suction. However, when the air discharged to the first discharge port and the air discharged to the second discharge port are mixed, temperature correction occurs. And, since the air temperature after the temperature correction is made to maintain a state higher than the temperature of the air sucked into the inlet 111, the overall heating action occurs.

Meanwhile, whether the heater 25 is operated may be adjusted according to the humidity of the indoor air in the heating process. In other words, when dehumidification is not necessary because the indoor humidity is not much higher than the set level, the desiccant 17 and the heater 25 may be kept in a stopped state. Then, the sucked indoor air passes through the evaporator 15 and only primary dehumidification by condensation is performed. Of course, the operation of the dehumidification unit is controlled by the controller in accordance with the indoor humidity value detected by the humidity sensor 70.

10 is a view showing the air flow when the cooling process is performed inside the air conditioner according to the first embodiment of the present invention.

Referring to FIG. 10, when the user selects the cooling mode, the refrigerant circulation cycle is activated and the blowing fan 12 rotates. In addition, the first damper 40 operates to shield the first discharge port 112 and the exhaust port 114 is opened. In addition, the second damper 41 operates to open the second discharge port 113.

In detail, the air passing through the condenser 14 is discharged to the outside through the exhaust port 114 as it is. The air passing through the evaporator 15 is dehumidified while passing through the dehumidifying unit, that is, the desiccant 17, and is then discharged into the room through the second discharge port 113. Then, the hot air sucked into the regeneration unit 20 is discharged to the outside through the regeneration exhaust port 115 after the regeneration process.

In the above process, the operation of the dehumidification unit may be determined according to the indoor humidity sensed by the humidity sensor 70. That is, when the humidity is not high, the dehumidification unit may not operate so that only dehumidification by condensation may be performed while passing through the evaporator 15. In the case of high temperature and high humidity, such as summer, the dehumidification unit is operated so that the condensation through the evaporator and the dehumidification through the dehumidification unit may be performed together.

Second Embodiment

11 is a view showing the air flow when the pure water heating process is performed in the air conditioner according to the second embodiment of the present invention.

Here, pure heating means raising only the room temperature without a separate dehumidification process.

In detail, the air conditioner 10 according to the second embodiment of the present invention has the same configuration as the first embodiment, except that a separate exhaust port is formed in the front of the cooling space. For convenience, the exhaust port formed in the front of the heating space is called the first exhaust port 114a, and the exhaust port formed in the front of the cooling space is called the second exhaust port 114b.

In the present embodiment, when the user selects the pure heating mode, the first exhaust port 114a is shielded by the first damper 40, and the second discharge port 113 is connected to the second damper 41. Is shielded. Therefore, the air heated while passing through the condenser 14 is discharged into the room through the first discharge port 112. The air passing through the evaporator 15 passes through the dehumidification unit and is discharged to the outside through the second exhaust port 114b. Here, whether the dehumidification unit is operated or not is an important factor. This is because both the air introduced into the regeneration unit 20 and the air passing through the evaporator 15 are discharged to the outside. Therefore, it may be advantageous in terms of energy savings that the dehumidification unit is not operated in the pure heating mode.

 In more detail, the air passing through the condenser 14 is discharged back to the room through the first discharge port 112, the air passing through the evaporator 15 and the air introduced into the regeneration unit 20 is It is discharged to the outside through the second exhaust port 114b and the regeneration exhaust port 115.

In addition, the heating mode and the cooling mode described in the first embodiment may be performed by adjusting the operation of the dampers 40 and 41.

In other words, when the second exhaust port 114b is shielded by the second damper 41 and the first exhaust port 114a is shielded by the first damper 40, as shown in FIG. 9. The same heating mode can be performed. When the first discharge port 112 is shielded by the first damper 40 and the second exhaust port 114b is shielded by the second damper 41, the cooling mode shown in FIG. 10 is performed. It is possible. In addition, whether the operation of the dehumidification unit or the operation of the heater 25 may be controlled according to the indoor humidity sensed by the humidity sensor 70.

Third Embodiment

12 is a view showing the air flow when the pure water heating process is performed in the air conditioner according to the third embodiment of the present invention.

In detail, the air conditioner 10 according to the third embodiment of the present invention has the same configuration as that of the first embodiment, except that the four-way valve V is mounted on the compressor outlet side to allow reverse circulation of the refrigerant. There is a difference in that it is not necessary to form a separate exhaust port in front of the cooling space of the case 11.

Referring to FIG. 12, when the user selects the pure heating mode, the controller controls the four-way valve V to allow the refrigerant to be circulated backward. That is, a transition from a refrigeration cycle to a heat pump cycle. Then, the condenser 14 performs the function of an evaporator, and the evaporator 15 performs the function of a condenser.

In FIG. 12, the evaporator 15 is provided on the left side and the condenser 14 is provided on the right side of the partition wall 16.

In detail, when the user selects the pure heating mode, the refrigerant circulation cycle performs the heat pump cycle, and the second discharge port 113 is opened by the operation of the second damper 41. The first discharge port 112 is shielded by the operation of the first damper 41.

Therefore, the intake air passing through the condenser 14 is discharged into the room through the second discharge port 113 after passing through the dehumidification unit. In addition, the air passing through the evaporator 15 is discharged to the outside through the exhaust port 114.

Here, a damper member is installed at the inlet of the regeneration suction duct 21 to block the low temperature air passing through the evaporator 15 from entering the regeneration unit 20, that is, the regeneration suction duct 21. You can do that. In addition, the damper member may be controlled by the control unit. In detail, even if there is no damper member at the inlet of the regeneration suction duct 21, there is no significant difference in heating effect, but the hot air passing through the condenser 14 causes heat exchange on the surface of the regeneration unit 20, thereby lowering the temperature. There is a sense of the existence of a damper in terms of blocking the source.

 According to such a configuration, as in the second embodiment, a pure heating process in which a dehumidification process is not performed while a heating process is performed may be performed.

In addition, by controlling the four-way valve (V) to switch to the refrigeration cycle, and by controlling the operation of the first damper 40 and the second damper 41, the same operation mode as in the first embodiment can be performed. Of course. Since the content has been described above, the description thereof will be omitted.

Fourth Embodiment

 13 is a view showing the air flow when the pure cooling process is performed in the air conditioner according to the fourth embodiment of the present invention.

In detail, the air conditioner 10 according to the fourth embodiment of the present invention has the same configuration as the first embodiment, except that there is no dehumidification unit. In other words, the desiccant 17 and the regeneration unit 20 do not exist, and only the refrigerant circulation cycle and the blower fan 12 exist.

This embodiment is a structure that can be easily replaced and changed from the first to third embodiments, and it is apparent that the present invention is included in the scope of the present invention. In addition, the present invention clearly shows that a technical difference exists in that both the condenser and the evaporator exchange heat with the indoor air, when compared with the conventional air conditioner where the air passing through the condenser and the air passing through the evaporator are different from each other.

 Referring to FIG. 13, when the user selects a pure cooling mode, that is, a process in which only cooling is performed without performing a separate dehumidification process, the first discharge port 112 is operated by the operation of the first damper 40. It is shielded and the exhaust port 114 is opened. The second discharge port is opened by the operation of the second damper 41. Then, the blowing fan 12 and the refrigeration cycle are operated together.

In addition, the indoor air sucked by the blower fan 12 is condensed while passing through the evaporator 15 to lower the absolute humidity, and then discharged into the room through the second discharge port 113. In addition, the indoor air passing through the condenser 14 is discharged to the outside through the exhaust port 114.

It can be seen that the pure cooling mode is performed in the room by the flow path structure as described above.

14 is a view showing the air flow when the heating process is performed inside the air conditioner according to the fourth embodiment of the present invention.

In detail, FIG. 14 is a state in which the dehumidification unit is removed under the same conditions as in FIG. 9.

Referring to FIG. 14, when the user selects a heating mode in the air conditioner 10 according to the present embodiment, the blower fan 12 and the refrigerating cycle are operated, and the first discharge port 112 and the first discharge port are operated. The two discharge ports 113 are all open. In addition, the exhaust port 14 is shielded by the first damper 40.

By the above configuration, the air passing through the condenser 14 is discharged into the room through the first discharge port 112, and the air passing through the evaporator 15 is also through the second discharge port 113. It is discharged to the room. Then, the air discharged into the room is mixed in the room and temperature correction occurs. As described in FIG. 9, even if temperature correction occurs, correction is made to a temperature higher than the initial room temperature. In addition, since there is no dehumidifying unit, a dehumidifying process in a practical sense is not performed, but since the absolute humidity is lowered by the process of condensing the sucked air through the evaporator 15, the effect of humidity control can also be obtained. .

Fifth Embodiment

15 is a view showing the air flow when the pure water heating process is performed in the air conditioner according to the fifth embodiment of the present invention.

In this embodiment, the structure is the same as the fourth embodiment, but there is a difference in that a separate exhaust port is provided in the front of the cooling space. A separate exhaust port is installed as described with reference to FIG. 11. Hereinafter, the exhaust port formed in the front surface of a heating space is called 1st exhaust port 114a, and the exhaust port formed in the front surface of a cooling space is called 2nd exhaust port 114b.

Referring to FIG. 15, when the user selects the pure heating mode, the blowing fan 12 and the refrigeration cycle are operated. The first discharge port 112 and the second exhaust port 114b are opened by the operation of the dampers 40 and 41, and the second discharge port 113 and the first exhaust port 114a are shielded.

Therefore, the intake air passing through the condenser 14 is discharged into the room through the first discharge port 112, and the intake air passing through the evaporator 15 is discharged to the outside through the second exhaust port 114b. do. By this flow path structure, it can be seen that the dehumidification process of lowering the humidity of the indoor air is not performed, but the pure heating mode of only raising the temperature of the indoor air is performed.

In addition, when the first discharge port 112 is shielded by the first damper 40 and the second exhaust port 114b is shielded by the second damper 41, the pure cooling mode may be performed. . Even in this case, a separate dehumidification process is not performed, but since moisture contained in the air sucked into the suction port 111 is condensed while passing through the evaporator 15 in the cooling process, dehumidification lowering absolute humidity is possible. .

In addition, when the first exhaust port 114a is shielded by the first damper 40, and the second exhaust port 114b is shielded by the second damper 41, heating combined with dehumidification is performed. This is the same as the case where the dehumidification unit does not operate in the first embodiment. That is, when the air passing through the condenser 14 and the air passing through the evaporator 15 are discharged into the room through the first discharge port 112 and the second discharge port 113, respectively, they are mixed with each other and temperature correction is performed. As the room temperature increases, indoor humidity decreases.

Sixth Embodiment

16 is a view showing the air flow when the pure water heating process is performed in the air conditioner according to the sixth embodiment of the present invention.

In this embodiment, the structure is the same as in the third embodiment, except that there is no dehumidification unit.

Referring to FIG. 16, when the user selects the pure heating mode, the controller controls the four-way valve V so that the refrigerant is circulated backward. That is, a transition from a refrigeration cycle to a heat pump cycle. Then, the condenser 14 performs the function of an evaporator, and the evaporator 15 performs the function of a condenser. This has already been explained in the third embodiment.

In detail, when the user selects the pure heating mode, the refrigerant circulation cycle performs the heat pump cycle, and the second discharge port 113 is opened by the operation of the second damper 41. The first discharge port 112 is shielded by the operation of the first damper 41.

Therefore, the intake air heated while passing through the condenser 14 is immediately discharged into the room through the second discharge port 113. In addition, the air passing through the evaporator 15 is discharged to the outside through the exhaust port 114.

In this state, if the four-way valve (V) is controlled to be converted into a refrigeration cycle, the heat exchanger existing on the right side of the partition wall 16 becomes an evaporator, and thus the freezing mode will be performed. In other words, the air passing through the evaporator is discharged to the room, and the air passing through the condenser is discharged to the outside, so that the room will be controlled to be cooled. Of course, dehumidification by the evaporator is performed in the cooling process as described above.

On the other hand, when the first damper 40 and the second damper 41 are operated so that both the first discharge port 112 and the second discharge port 113 are opened, mixing is performed regardless of the state of the refrigerant circulation cycle. Heating is carried out.

In other words, since both the air passing through the condenser and the air passing through the evaporator are discharged to the room, the heating process by temperature correction is performed.

Seventh Example

17 is a perspective view schematically showing the configuration of an air conditioner according to a seventh embodiment of the present invention.

Referring to FIG. 17, the air conditioner 10 according to the seventh embodiment is the same as that of the first embodiment in the configuration, except that the regenerative exhaust duct 23 is not connected to the outside and the evaporator 15 is connected. There is a difference in being placed in front of the.

  As shown, the regenerative exhaust duct 23 is located in front of the evaporator 15, thereby eliminating the need for a condensation device for condensing air discharged to the outside through the regenerative exhaust duct 23, as well as the regenerative exhaust duct 23. There is no need for a drip tray to collect condensate that condenses as it passes through (23).

In other words, the air discharged from the regenerative exhaust duct 23 meets the intake air sucked through the inlet 111 and the temperature is first lowered and condensed while passing through the evaporator 15. Therefore, moisture contained in the air passing through the regeneration exhaust duct 23 is condensed while passing through the evaporator 15, and condensate is collected in the drain pan 19, so that a separate drip tray is not necessary.

In addition, since the regenerative exhaust duct 23 is not connected outdoors, there is an advantage that the outdoor exhaust duct 60 connected to the regenerative exhaust duct 23 is not required. Therefore, the installation cost can be reduced.

In the structure of the air conditioner 10 according to the present embodiment, the mixed heating is performed by opening both the first discharge port 112 and the second discharge port 113.

In other words, a mixed fluid of intake air passing through the condenser 14 and intake air and regeneration air passing through the evaporator 15 is discharged into the room. Then, heating is performed while temperature correction is made during mixing of the discharged air.

In addition, although not shown, various operating modes may be performed if an exhaust port (corresponding to the second exhaust port in the previous embodiment) is formed on the front surface of the heating space in which the dehumidification unit is seated.

In detail, when the first outlet 112 is shielded by the first damper 40 and the second outlet 113 is opened, the cooling mode will be performed. When the dehumidification unit is operated, cooling and dehumidification modes will be performed, and the dehumidification intensity will be adjusted according to whether the heater 25 inside the regeneration unit 20 is operated.

In addition, when the second discharge port 113 is shielded by the second damper 41, the exhaust port formed on the front surface of the cooling space is opened, and the exhaust port 114 is blocked by the first damper 40. Since only the air passing through the condenser 14 is discharged into the room, the pure heating mode can also be performed. In this mode, since all the air passing through the evaporator 15 will be discharged to the outside, the operation of the dehumidification unit will be unnecessary.
