In addition, the outdoor air introduced through the inlet 210a of the second air flow path 210 by the operation of the second blower 260 is filtered through the filters 220 and 230 and the second inlet 420 of the flow path switching unit 400 . and the second outlet 440 , and the second heat exchanger 250 , and then passes through the second region 320 . In this case, in the outdoor air, moisture is adsorbed to the adsorbent in the second region 320 , and the second heat exchanger 250 operates as an evaporator to lower the temperature of the outdoor air passing through, thereby increasing the amount of moisture adsorbed.

When the adsorbent to which moisture of outdoor air has been adsorbed in the second region 320 is located in the first region 310 by the rotation of the rotor member 300 , the indoor air heated while passing through the first heat exchanger 150 . Evaporates moisture while passing through the adsorbent in the first region 310 to form humid indoor air. The indoor air passing through the first region 310 is discharged into the room through the outlet portion 110c of the first air flow path 110 .

On the other hand, since the indoor air is discharged into the room after the temperature is increased due to heating in the first heat exchanger 150, there is also an indoor heating effect.

A water supply humidification mode will be described with reference to FIG. 3 .

The water supply humidification mode refers to a mode in which the moisture supply unit 500 humidifies the indoor air while supplying moisture to the third region 330 .

In the flow path switching unit 400, the direction switching gate is set to the first position, the first blower 160 and the second blower 260 are turned on, and the compressor 610 is turned on, so that the refrigerant is The first refrigerant is circulated along the circulation path, and the rotation of the rotor member 300 is the same as in the no-water humidification mode.

In the water supply humidification mode, moisture is supplied from the water supply unit 500 to the third region 330 , and the direction of the damper 280-1 is connected to the bypass flow path 285-1. There is a difference.

The indoor air flows through the first air flow path 110 by the operation of the first blower 160, and the first heat exchanger 150 operates as a condenser by the operation of the compressor 610, so that the first air flow path 110 ) to heat the flowing air, and the second heat exchanger 250 operates as an evaporator.

Meanwhile, in the water supply unit 500 , the water supply valve 550 is opened to supply moisture to the third region 330 , the water tank 530 is filled with water, and the third blower 510 is turned on. The air circulating in the humidified air flow path 540 becomes humid air while passing through the humidifying filter 520 and flows to the third region 330 of the rotor member 300 . The moisture adsorbed in the third region 330 is positioned in the first region 310 by rotation of the rotor member 300 .

The indoor air heated while passing through the first heat exchanger 150 passes through the first region 310 of the rotor member 300 . In this case, since the adsorbent that has absorbed moisture in the third region 330 is rotated and located in the first region 310 , the heated indoor air passes through the first region 310 and evaporates the moisture of the adsorbent to create a humid environment. create indoor air. The indoor air passing through the first region 310 is discharged into the room through the outlet portion 110c of the first air flow path 110 . This results in indoor heating along with indoor humidification.

In this case, the damper 280-1 is oriented so as to be connected from the middle part 210b of the second air flow path 210 to the bypass flow path 285-1, and passes through the second heat exchanger 250. The outdoor air does not pass through the second region 320 and is discharged to the outdoors through the bypass passage 285 - 1 . If the cold outdoor air is discharged to the outside through the outlet 210c of the second air passage 210 after passing through the second region 320, the adsorbent is transferred from the second region 320 to the first region ( 310), the temperature of the cold outdoor air is transmitted, so there is a problem in that more energy for indoor heating is consumed. Accordingly, in the present invention, energy loss can be minimized by allowing the cold outdoor air to be discharged to the outdoors through the bypass flow path 285 - 1 without passing through the second region 320 .

A dehumidification mode will be described with reference to FIG. 4 .

When the dehumidification mode is activated, the direction change gate is set to the first position in the flow path switching unit 400 , the first blower 160 , the second blower 260 , and the compressor 610 are turned on, and the rotor The member 300 rotates, the moisture supply unit 500 does not supply moisture, and the flow path direction of the damper 280-1 allows outdoor air to flow toward the outlet portion 210c of the second air flow path 210. The setting is the same as for the no-water humidification mode.

When the compressor 610 is turned on in the dehumidification mode, the refrigerant circulates along the second refrigerant circulation path. In this case, the first heat exchanger 150 operates as an evaporator, and the second heat exchanger 250 operates as a condenser.

When the first blower 160 is operated, the indoor air introduced through the inlet 110a of the first air flow path 110 is cooled while passing through the first heat exchanger 150, and the cooled air is cooled in the first area ( While passing through the 310 , moisture contained in the indoor air is adsorbed to the adsorbent of the first region 310 . The indoor air from which moisture has been removed from the first area 310 is discharged into the room through the outlet 110c of the first air flow path 110 . In this case, since the temperature of the air discharged into the room is lowered, there is also an indoor cooling effect.

When the second blower 260 is operated, the outdoor air introduced through the inlet 210a of the second air flow path 210 is heated while passing through the second heat exchanger 250, and the heated air is heated in the second region ( 320) is passed. When the adsorbent of the rotor member 300 that has absorbed moisture in the indoor air in the first region 310 rotates and is positioned in the second region 320 , it is absorbed by the heated outdoor air passing through the second region 320 . As a result, moisture in the adsorbent is evaporated, and the outdoor air becomes wet air and is discharged to the outdoors through the outlet portion 210c of the second air flow path 210 .

By this process, the indoor air is dehumidified, and a comfortable indoor environment can be maintained.

The cooling mode will be described with reference to FIG. 5 .

In the cooling mode, the direction change gate is set to the first position in the flow path switching unit 400, the first blower 160 and the second blower 260 are turned on, and the compressor 610 is turned on. ), the refrigerant circulates along the second refrigerant circulation path, and the moisture supply unit 500 does not supply moisture, which is the same as the dehumidification mode. Accordingly, the first heat exchanger 150 operates as an evaporator, and the second heat exchanger 250 operates as a condenser. In this case, the rotor member 300 may be configured to rotate or may be configured to not rotate.

In the cooling mode, the direction of the flow path of the damper 280-1 is set so that the outdoor air that has passed through the second heat exchanger 250 is discharged to the outside through the bypass flow path 285-1, so that heat loss for indoor cooling It is different from the dehumidification mode in that it can minimize

That is, the damper 280-1 is connected from the middle part 210b of the second air flow path 210 to the bypass flow path 285-1, and the direction is so that the connection to the second region 320 is blocked. is set Accordingly, the outdoor air passing through the second heat exchanger 250 does not pass through the second region 320 and is discharged to the outdoors through the bypass passage 285 - 1 . If the outdoor air heated in the second heat exchanger 250 passes through the second region 320 and then is discharged to the outside through the outlet portion 210c of the second air flow path 210, the second region ( 320), the adsorbent rotates to the first region 310, and then transfers heat to the indoor air passing through the first region 310 through the outlet portion 110c of the first air flow path 110. Since the temperature of the air discharged into the room increases, there is a problem in that more energy is consumed for cooling the room. Accordingly, in the present invention, energy loss for cooling can be minimized by allowing the heated outdoor air to be discharged to the outdoors through the bypass flow path 285-1 without passing through the second region 320 .

The indoor cooling is performed by this process.

The ventilation mode will be described with reference to FIG. 6 .

When the ventilation mode is activated, the first blower 160 and the second blower 260 are operated. In this case, the direction change gate of the flow path switching unit 400 has a second position where the first inlet 410 and the second outlet 440 are connected, and the second inlet 420 and the first outlet 430 are connected. is set to be In addition, the compressor 610 is in an off state, and moisture is not supplied from the moisture supply unit 500 .

The indoor air sucked into the inlet part 110a of the first air flow path 110 by the operation of the second blower 260 passes through the flow path switching unit 400 and the second area 320 and then the second It is discharged to the outdoors through the outlet part 210c of the air flow path 210 .

At the same time, the outdoor air sucked into the inlet part 210a of the second air flow path 210 by the operation of the first blower 160 passes through the flow path switching unit 400 and passes through the first area 310. It is discharged into the room through the outlet part 110c of the first air flow path 110 .

Through this process, indoor air is discharged to the outdoors, and the outdoor air is introduced into the room through the plurality of filters 220, 130, and 140, thereby ventilating the indoor air.

When the flow path switching unit 400 is configured to change the flow path as described above, in the ventilation mode, outdoor air is filtered by the filters 220 and 230 provided in the second air flow path 210 and then transferred to the first air flow path 110 . Since it is filtered by the provided filters 130 and 140, it is filtered while passing through many filters 220, 230, 130, 140 provided in the first air flow path 110 and the second air flow path 210, and then flows into the room, so that clean air can be supplied to the room. can

A humidification ventilation mode will be described with reference to FIG. 7 .

The humidification ventilation mode refers to a mode in which the moisture supply unit 500 supplies moisture to the third region 330 to humidify the indoor air and ventilate the indoor air.

When the humidification ventilation mode is activated, the first blower 160 and the second blower 260 are operated, and the direction switching gate of the flow path switching unit 400 is set to the second position, which is the same as the ventilation mode.

In addition, moisture is supplied from the moisture supply unit 500 to the third region 330 , the direction of the damper 280-1 is connected to the bypass flow path 285-1, and the compressor 610 operates The first heat exchanger 150 operates as a condenser, and the second heat exchanger 250 operates as an evaporator, which is the same as the water supply humidification mode.

In the same method as described in the water supply humidification mode, the moisture supplied from the moisture supply unit 500 is adsorbed to the adsorbent in the third region 330 of the rotor member 300 , and the moisture is adsorbed in the third region 330 . is positioned in the first region 310 by the rotation of the rotor member 300 .

The outdoor air sucked into the inlet part 210a of the second air flow path 210 by the operation of the first blower 160 is heated in the first heat exchanger 150 through the flow path switching unit 400 and heated. As the exhausted outdoor air passes through the first region 310, moisture in the adsorbent is evaporated to form humid air. The outdoor air passing through the first region 310 is discharged into the room through the outlet portion 110c of the first air flow path 110 .

The indoor air sucked into the inlet part 110a of the first air flow path 110 by the operation of the second blower 260 passes through the flow path switching unit 400 and the second heat exchanger 250 . In this case, the direction of the damper 280-1 is set to be connected from the middle part 210b of the second air flow path 210 to the bypass flow path 285-1. Accordingly, the outdoor air passing through the second heat exchanger 250 does not flow in the direction of the second region 320 and is discharged to the outside through the bypass passage 285 - 1 . If the indoor air cooled while passing through the second heat exchanger 250 passes through the second region 320 , the adsorbent whose temperature has decreased in the second region 320 rotates to the first region 310 . Since the temperature of the outdoor air flowing through the furnace can be lowered, more heat energy for heating the outdoor air in the first heat exchanger 150 can be consumed. Accordingly, in the present invention, energy loss can be minimized by allowing the indoor air cooled in the second heat exchanger 250 to be discharged to the outdoors through the bypass flow path 285-1 without passing through the second region 320 .

By this process, ventilation is performed together with humidification of the indoor air.

<Second embodiment>

The configuration of the air conditioner according to the second embodiment of the present invention will be described with reference to FIG. 8 .

The air conditioner of the second embodiment includes a third heat exchanger 170 and a fourth heat exchanger 270 and It includes a heat pump 600 having a first expansion valve 630-1 and a second expansion valve 630-2, a damper 280-2, a bypass passage 285-2, and a second blower. It is different from the first embodiment in that the position of 260 is different, and the rest of the configuration is the same.

The third heat exchanger 170 is provided between the first region 310 and the first blower 160 to exchange heat with the air that has passed through the first region 310 . The fourth heat exchanger 270 is provided between the second region 320 and the second blower 260 to exchange heat with the air that has passed through the second region 320 .

The refrigerant supplied from the compressor 610 circulates through any one of the third refrigerant circulation path 640 - 1 and the fourth refrigerant circulation path 640 - 2 in the four-way valve 620 . On the third refrigerant circulation path 640-1, a first heat exchanger 150, a first expansion valve 630-1, and a fourth heat exchanger 270 are provided. On the fourth refrigerant circulation path 640-2, a second heat exchanger 250, a second expansion valve 630-2, and a third heat exchanger 170 are provided.

During indoor humidification and heating, the first heat exchanger 150 and the fourth heat exchanger 270 operate as a condenser and an evaporator, and during indoor dehumidification and cooling, the second heat exchanger 250 and the third heat exchanger ( 270) works as a condenser and evaporator.

In addition, in the second air flow path 210 connecting the outlet of the second region 320 and the one outdoor side in the second air flow path 210 , a damper 280 - 2 , a fourth heat exchanger 270 , and a second The blower 260 is sequentially provided. The second air flow path 210 in which the damper 280-2 is located is connected so that the bypass flow path 285-2 intersects. The damper 280 - 2 sets the flow direction of the air so that the outdoor air introduced through the bypass passage 285 - 2 is discharged to the outside through the outlet 210c of the second air passage 210 . Alternatively, the air that has passed through the second region 320 is discharged to the outside through the outlet portion 210c of the second air passage 210 .

According to this configuration, the inside of the first air flow path 110 and the inside of the second air flow path 210 are always kept in a dry state, so that polluted air containing moisture does not flow into the room. That is, when the fourth heat exchanger 270 operates as an evaporator, dew condensation may occur at the outlet portion 210c of the second air flow path 210, but it is not introduced into the room but is exhausted to the outside. You can keep the inside clean. In addition, when the first heat exchanger 150 operates as an evaporator, dew condensation may occur in the middle portion 110b of the first air flow path 110 , but it contains moisture so that air passes through the first region 310 . When moisture is adsorbed by the adsorbent of the first region 310 , the inside of the first air flow path 110 may be maintained in a dry state. In addition, since the four heat exchangers 150 , 250 , 170 , 270 and the flow path switching unit 400 are provided, indoor cooling and heating, humidity control, air cleaning and ventilation are all possible in one device.

Hereinafter, a method for controlling an air conditioner according to the present invention will be described with reference to FIGS. 9 to 13 .

A non-water humidification mode will be described with reference to FIG. 9 .

In the flow path switching unit 400, the direction changing gate is set to the first position, the first blower 160, the second blower 260, and the compressor 610 are turned on, and the rotor member 300 is rotated. This is the same as the waterless humidification mode of the first embodiment. In addition, the damper 280-2 is similar to the first embodiment in that the direction is set so that the outdoor air flows in the direction of the outlet portion 210c of the second air passage 210 after passing through the second region 320. same.

When the compressor 610 is turned on, the refrigerant operates the four-way valve 620 , the first heat exchanger 150 , the first expansion valve 630-1, the fourth heat exchanger 270 , and the compressor 610 . cycle along At this time, the path through which the refrigerant flows is referred to as a third refrigerant circulation path 640-1.

The indoor air introduced through the inlet portion 110a of the first air flow path 110 by the operation of the first blower 160 is heated while passing through the first heat exchanger 150 operating as a condenser, and then is heated in the first area. (310) is passed.

The outdoor air introduced through the inlet 210a of the second air passage 210 by the operation of the second blower 260 passes through the second region 320 . In this case, the moisture contained in the outdoor air is adsorbed to the adsorbent of the second region 320 . The outdoor air passing through the second region 320 passes through the fourth heat exchanger 270 operating as an evaporator and then is discharged to the outside.

When the adsorbent to which moisture of outdoor air has been adsorbed in the second region 320 is located in the first region 310 by the rotation of the rotor member 300 , the indoor air heated while passing through the first heat exchanger 150 . Evaporates moisture while passing through the adsorbent in the first region 310 to form humid indoor air. The indoor air that has passed through the first region 310 is discharged into the room through the outlet portion 110c of the first air flow path 110 to perform indoor humidification.

In this case, since the refrigerant does not flow in the second heat exchanger 250 and the third heat exchanger 170, it has no effect on the indoor air and the outdoor air.

A heating and water supply humidification mode will be described with reference to FIG. 10 .

In the heating and water supply humidification mode, the direction change gate is set to the first position in the flow path switching unit 400, and the first blower 160, the second blower 260 and the compressor 610 are turned on, Rotation of the rotor member 300 is the same as in the non-water humidification mode. Also, the refrigerant flows along the third refrigerant circulation path 640-1, so that the first heat exchanger 150 operates as a condenser and the fourth heat exchanger 270 operates as an evaporator.

In the heating and water supply humidification mode, moisture is supplied from the moisture supply unit 500 to the third region 330, and the direction of the damper 280-2 is from the bypass flow path 285-1 to the second air flow path 210. It is different from the non-water humidification mode in that it is connected to the outlet portion 210c of

The indoor air flows through the first air flow path 110 by the operation of the first blower 160, the first heat exchanger 150 operates as a condenser by the operation of the compressor 610, and the second heat exchanger ( 250) works as an evaporator.

The indoor air heated while passing through the first heat exchanger 150 passes through the first region 310 of the rotor member 300 . In this case, the adsorbent that has absorbed moisture in the third region 330 is rotated and positioned in the first region 310 , and the heated indoor air passes through the first region 310 to evaporate moisture in the adsorbent to form humid indoor air. to form The indoor air passing through the first region 310 is discharged into the room through the outlet portion 110c of the first air flow path 110 . This results in indoor heating along with indoor humidification.

On the other hand, by the operation of the second blower 260, the outdoor air flows in through the bypass passage 285-2, passes through the fourth heat exchanger 270, and passes through the outlet portion 210c of the second air passage 210. It is discharged to the outside through the other side. Accordingly, since the cold outdoor air does not pass through the second region 320 , it is possible to prevent the cold outdoor air from affecting the temperature of the air passing through the first region 310 , thereby minimizing energy loss.

The dehumidification and cooling mode will be described with reference to FIG. 11 .

In the dehumidification and cooling mode, the direction change gate is set to the first position in the flow path switching unit 400 , the first blower 160 , the second blower 260 , and the compressor 610 are turned on, and the rotor The member 300 rotates, and the point that moisture is not supplied from the moisture supply unit 500 is the same as in the no-water humidification mode.

When the compressor 610 is turned on in the dehumidification mode, the refrigerant is transferred to the compressor 610, the four-way valve 620, the second heat exchanger 250, the second expansion valve 630-2, and the third heat exchanger ( 170), circulates along the compressor 610. At this time, the path through which the refrigerant flows is referred to as a fourth refrigerant circulation path 640-2.

In this case, the second heat exchanger 250 operates as a condenser, and the third heat exchanger 170 operates as an evaporator.

When the first blower 160 is operated, the indoor air passes through the first region 310 , and moisture contained in the indoor air is adsorbed to the adsorbent of the first region 310 . The indoor air from which moisture has been removed from the first area 310 is discharged into the room through the outlet 110c of the first air flow path 110 . In this case, since the temperature of the air discharged into the room is lowered by the third heat exchanger 170, there is an effect of cooling the room.

When the second blower 260 is operated, the outdoor air introduced through the inlet 210a of the second air flow path 210 is heated while passing through the second heat exchanger 250, and the heated air is heated in the second region ( 320) is passed. When the adsorbent of the rotor member 300 that has absorbed moisture in the indoor air in the first region 310 rotates and is positioned in the second region 320 , it is absorbed by the heated outdoor air passing through the second region 320 . As a result, moisture in the adsorbent is evaporated, and the outdoor air becomes wet air and is discharged to the outdoors through the outlet portion 210c of the second air flow path 210 .

By this process, the indoor air is dehumidified, and a comfortable indoor environment can be maintained.

An air cleaning mode will be described with reference to FIG. 12 .

In the air cleaning mode, the first blower 160 is turned on, and the direction changing gate of the flow path switching unit 400 is set to the first position. The compressor 610 is turned off, and moisture is not supplied from the moisture supply unit 500 .

The indoor air introduced through the inlet portion 110a of the first air flow path 110 due to the operation of the first blower 160 is subjected to primary filtration of foreign substances with large particles in the pre-filter 120, and is functional. After the harmful factors such as allergy are removed from the filter 130 , the particulates are removed from the HEPA filter 140 .

The indoor air passing through the HEPA filter 140 passes through the first region 310 and then is discharged into the room through the outlet portion 110c of the first air flow path 110, thereby purifying the indoor air.

In this case, to remove the smell of the indoor air, the rotor member 300 is rotated and the second blower 260 is operated.

Since the surface of the adsorbent of the rotor member 300 is coated with a polymer desiccant, odor is removed when indoor air comes into contact with the surface of the adsorbent.

The ventilation mode will be described with reference to FIG. 13 .

When the ventilation mode is activated, the first blower 160 and the second blower 260 are operated. In this case, the direction changing gate of the flow path switching unit 400 is set to the second position. The compressor 610 is turned off, and moisture is not supplied from the moisture supply unit 500 .

The indoor air sucked into the inlet part 110a of the first air flow path 110 by the operation of the second blower 260 is connected to the pre-filter 120 and the first inlet 410 of the flow path switching unit 400 and After passing through the second area 320 of the rotor member 300 through the second outlet 440 , it is discharged to the outside through the outlet 210c of the second air flow path 210 .

At the same time, the outdoor air sucked into the inlet 210a of the second air flow path 210 by the operation of the first blower 160 is a pre-filter 220, a medium filter 230, and a flow path switching unit 400. After passing through the first region 310 of the rotor member 300 through the second inlet 420 and the first outlet 430, the functional filter 130, and the HEPA filter 140 of the first air flow path ( It is discharged into the room through the outlet portion (110c) of 110).

By this process, indoor air is discharged to the outside, and the outdoor air is introduced into the room through a plurality of filters 220,230, 130, and 140 to ventilate the indoor air.

If the flow path switching unit 400 is configured to change the flow path as described above, in the ventilation mode, outdoor air is filtered by the pre-filter 220 and the medium filter 230 provided in the second air flow path 210 and then removed. Since it is also filtered by the functional filter 130 and the HEPA filter 140 provided in the first air flow path 110, many filters 220, 230, 130, 140 provided in the first air flow path 110 and the second air flow path 210 are passed through. Since it flows into the room after being filtered, clean air can be supplied to the room.

In addition, the functional filter 130 and the HEPA filter 140 can filter the indoor air introduced through the inlet 110a of the first air flow path 110 in humidification mode, heating mode, air cleaning mode, and dehumidification mode. In addition, since the outdoor air introduced through the inlet 210a of the second air flow path 210 is also filtered in the ventilation mode, there is no need to separately provide a filter for filtering the indoor air and the outdoor air.

According to the configuration as described above, by using two or four heat exchangers using the heat pump 600 to function as a condenser and an evaporator, respectively, indoor air conditioning and humidity control can be implemented in one device, and air conditioning capacity and humidity control ability can be improved.

In addition, by providing the flow path switching unit 400 at the point where the flow paths 110 and 210 of the indoor air and the outdoor air intersect, it is possible to implement both humidity control, heating, air cleaning, and ventilation modes by a simple structure.

In addition, four heat exchangers 150, 250, 170, 270 constituting the heat pump 600 before and after the rotor member 300 are provided in the first air flow path 110 and the second air flow path 210, and the heat exchanger (150, 250, 170, 270). By alternately operating the air conditioners, it is possible to keep the inside of each air passage in a dry state at all times, so that the air conditioner can be maintained in a clean state.

<Electric heat exchangeable flow path conversion part>

In the above, the flow path switching unit 400 is configured as a damper to achieve only flow path switching, but with reference to FIGS. 14 to 15 , not only the flow path switching unit 700 but also total heat exchange can be performed. An embodiment configured so as to be described will be described.

The present embodiment has the same configuration as described above, except that the flow path switching unit 400 is replaced with the flow path switching unit 700 in which total heat exchange is performed.
