When the direction of the damper 280 is set so that the outlet 210c of the second air passage 210 and the bypass passage 285 are connected, the outdoor cold air introduced through the bypass passage 285 is provided. Since the air is discharged again through the outlet portion 210c of the second air passage 210 to the outside, outdoor air does not flow to the second region 320. If the cold outdoor air passes through the second region 320, the adsorbent whose temperature has fallen in the second region 320 rotates and is positioned in the first region 310, so that the temperature of the air flowing into the room is reduced. Loss occurs. Therefore, since the damper 280 and the bypass passage 285 are provided, heat loss may be prevented from occurring due to cold outdoor air.

In the second region 320, foreign matter may be adsorbed while passing outdoor air. As such, when water is supplied to the adsorbent in which the foreign matter is adsorbed in the second region 320, mold may occur, making it difficult to maintain a clean state.

Therefore, in the present embodiment, the moisture supplied from the water supply unit 500 is configured to be supplied to the third region 330 independent of the first region 310 and the second region 320.

However, the third region 330 may not be formed independently, and the third region 330 may be configured as one region with the second region 320. In this case, the moisture supplied from the moisture supply unit 500 may be configured to be supplied to the second region 320.

The first region 310, the second region 320, and the third region 330 are separated from each other, and the adsorbent of the rotor member 300 is driven by a driving unit (not shown) about an axis provided at the center thereof. It is supposed to rotate.

When air passes through the humidification filter 520, the moisture adsorbed on the humidification filter 520 evaporates to become humid air and flows along the humidification air flow path 540 to the third region 330.

After moisture is adsorbed to the adsorbent of the third region 330, the dried air flows again to the humidification filter 520 by the third blower 510. As such, the humidified air flow path 540 may be formed as a waste flow path.

It consists of a valve 620.

When the heat pump 600 is heated, the refrigerant is a compressor 610, a four-way valve 620, a first heat exchanger 150, a first expansion valve 630-1, and a fourth heat exchanger 270. ), And circulates along the compressor 610. Such a circulation path of the refrigerant is referred to as a first refrigerant circulation environment path 640-1. In this case, the first heat exchanger 150 is operated as a condenser to heat the air flowing through the first air flow path 110, and the fourth heat exchanger 270 is operated as an evaporator to flow the second air flow path 210. To cool the air.

When the heat pump 600 is cooled, the refrigerant is a compressor 610, a four-way valve 620, a second heat exchanger 250, a second expansion valve 630-2, and a third heat exchanger 170. , Circulates along the compressor 610. Such a circulation path of the refrigerant is referred to as a second refrigerant circulation environment path 640-2. In this case, the second heat exchanger 250 is operated as a condenser to heat the air flowing through the second air flow path 210, and the third heat exchanger 170 is operated as an evaporator to flow the first air flow path 110. To cool the air.

The air heated or cooled in the first heat exchanger 150 flows in the direction of the first region 310 of the rotor member 300, and the air heated or cooled in the second heat exchanger 250 includes the rotor member ( It flows in the direction of the second area 320 of 300.

Hereinafter, a method of controlling the air conditioner according to the first embodiment will be described with reference to FIGS. 2 to 6.

The water-free water humidification mode will be described with reference to FIG. 2.

The non-water humidification mode refers to a mode in which the indoor humidification is performed using moisture included in outdoor air in a state in which moisture is not supplied from the moisture supply unit 500 to the third region 330.

Flow path switching unit 400 is the first inlet 410 and the first outlet 430 is connected, the second inlet 420 and the second outlet 440 so that the direction switching gate is connected It is set to the first position.

In addition, the first blower 160, the second blower 260, and the compressor 610 are turned on, and the rotor member 300 rotates. The damper 280 is set in a direction such that air passing through the second region 320 flows toward the outlet 210c of the second air flow path 210.

When the compressor 610 is turned on, the refrigerant circulates along the first refrigerant circulation environment. In this case, the first heat exchanger 150 is operated as a condenser to heat the air flowing through the first air flow path 110, and the second heat exchanger 250 is operated as an evaporator.

Meanwhile, the indoor air introduced into the indoor unit 1 through the inlet 110a of the first air passage 110 by the operation of the first blower 160 is pre-filter 120, the functional filter 130, the flow path After passing through the conversion unit 400, the first heat exchanger 150, the first region 310, and the HEPA filter 230, the discharge unit 400 is discharged into the room. In this case, the indoor air is heated while passing through the first heat exchanger 150.

In addition, the outdoor air introduced through the inlet portion 210a of the second air passage 210 by the operation of the second blower 260 may be a pre-filter 220, a flow path switching unit 400, a second heat exchanger ( After passing through 250 sequentially, it passes through the second region 320. In this case, the moisture contained in the outdoor air is adsorbed by the adsorbent in the second region 320, and the temperature of the outdoor air passing through the second heat exchanger 250 as the evaporator is lowered to increase the amount of moisture adsorbed.

When the adsorbent in which the moisture of the outdoor air is absorbed in the second region 320 is positioned 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. Moisture is evaporated while passing through the adsorbent in the first region 310 to form wet indoor air. The indoor air passing through the first area 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, the indoor air and the outdoor air have no influence.

The heating and water supply humidification modes will be described with reference to FIG. 3.

In the heating and water supply humidification mode, the direction switching 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. Rotation of the rotor member 300 is the same as in the water free humidification mode. In addition, the refrigerant flows along the first refrigerant flow path 640-1, so that the first heat exchanger 150 operates as a condenser and the fourth heat exchanger 270 operates as an evaporator.

Water is supplied from the water supply unit 500 to the third region 330, and the direction of the damper 280 is connected from the bypass passage 285 to the outlet 210c of the second air passage 210. It is different from the no water humidification mode.

The water supply unit 500 has a water supply valve 550 open to supply water to the third region 330 so that the water tank 530 is filled with water, and the third blower 510 is turned on to humidify the air. Air circulating in the flow path 540 passes through the humidification filter 520 and becomes humid air and flows to the third region 330 of the rotor member 300. Water adsorbed in the third region 330 is positioned in the first region 310 by the rotation of the rotor member 300.

Indoor air flows through the first air passage 110 by the operation of the first blower 160. 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 adsorbing the 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 the moisture of the adsorbent to moist indoor air. To form. The indoor air passing through the first area 310 is discharged into the room via the outlet 110c of the first air passage 110. This results in room heating with room humidification.

On the other hand, by the operation of the second blower 260, the outdoor air is introduced through the bypass flow passage 285 through the fourth heat exchanger 270 through the outlet 210c of the second air flow passage 210 on the other side. It is discharged to the outdoors. Therefore, since the cold outdoor air does not pass through the second region 320, the cold outdoor air may be prevented from affecting the temperature of the air passing through the first region 310, thereby minimizing energy loss.

The dehumidification and cooling modes will be described with reference to FIG. 4.

In the dehumidification and cooling modes, the direction switching 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. The member 300 is rotated, and the moisture is not supplied from the moisture supply unit 500 in the same manner as in the water-free humidification mode.

When the compressor 610 is turned on in the dehumidification mode, the refrigerant circulates along the second refrigerant circulation environment 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, indoor air passes through the first region 310, and moisture contained in the indoor air is adsorbed by the absorbent material of the first region 310. The indoor air from which moisture is removed from the first area 310 is discharged into the room through the outlet portion 110c of the first air passage 110. In this case, since the temperature of the air discharged to the room is lowered in the third heat exchanger 170, there is room cooling effect.

When the second blower 260 is operated, outdoor air introduced through the inlet portion 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 area ( 320). When the adsorbent of the rotor member 300, which absorbs moisture of indoor air in the first region 310, is rotated and positioned in the second region 320, the heated outdoor air passing through the second region 320. As a result, the moisture of the adsorbent is evaporated so that the outdoor air is in a humid air state and discharged to the outside through the outlet portion 210c of the second air flow path 210.

The dehumidification of the indoor air is made by such a process, thereby maintaining a comfortable indoor environment.
