In the second region 320, foreign matter can be adsorbed while outdoor air passes through the second region 320. If moisture is supplied to the second region 320 in which the foreign matter is adsorbed, molds may be generated and it is difficult to maintain the clean state.

Therefore, in this embodiment, the moisture supplied from the water supply unit 500 is supplied to the third region 330, which is 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 formed as one region with the second region 320. In this case, the moisture supplied from the water supply unit 500 may be supplied to the second area 320.

The hot water supply valve 251 is opened for heating the outdoor air in the second heat supply unit 250 and the hot water supplied through the hot water supply pipe 152 and the hot water supply valve 251 is supplied to the second heat supply unit 250, Exchanged with the outdoor air flowing through the second air passage 210.

The heated outdoor air passing through the second heat radiating part 250 passes through the second area 320 of the rotor member 300. When the adsorbent of the rotor member 300 which absorbs the moisture of indoor air in the first region 310 rotates and is located in the second region 320, the heated outdoor air passing through the second region 320 The moisture of the adsorbent is evaporated and the outdoor air is humidified and discharged to the outside through the outlet 210c of the second air passage 210. [

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

The ventilation mode will be described with reference to Fig.

When the ventilation mode is activated, the first blower 160 and the second blower 260 are operated. The direction switching gate 450 of the flow path switching unit 400 is connected to the first inlet 410 and the second outlet 440 so that the second inlet 420 and the second outlet 440 are connected 2 position.

[ Control method of A first air passage 110 having both ends connected to the inside of the room, a second air passage 210 having both ends connected to the outside, a first region 310 provided on the first air passage 110, A second region 320 provided on the first region 210 and a rotor member 300 composed of a sorbent material alternately passing through the first region 310 and the second region 320 by rotation, As a control method,
a) an inlet portion 110a of the first air passage 110 and an inlet portion 110a of the first air passage 110 are connected by a flow path switching portion 400 provided at a point where the first air passage 110 and the second air passage 210 intersect, (310), and connecting the inlet (210a) of the second air passage (210) to the second area (320);
b) activating a first mode for allowing indoor air introduced through an inlet portion (110a) of the first air passage (110) to flow into the room through the first region (310);
c) the inlet 110a of the first air passage 110 is connected to the second area 320 and the inlet 210a of the second air passage 210 is connected to the first area 310 The flow path switching unit 400 switches the flow direction of the fluid;
d) The indoor air introduced through the inlet portion 110a of the first air passage 110 is allowed to flow out of the room through the second region 320, and at the same time, And a second mode in which the outdoor air flowing through the first area (210a) flows into the indoor space through the first area (310)
In the step d), the rotor member 300 rotates to exchange heat between outdoor air passing through the first region 310 and indoor air passing through the second region 320, 20. The method of claim 19,
The water supply unit 500 includes a humidifying filter 520 provided on the humidifying air passage 540 which is a closed channel and containing water and a humidifying filter 520 provided on the humidifying air passage 540, And a third blower (510) for flowing the humidified air passing through the second blower (510);
And the humidification air flow path (540) is dried by operating the third blower (510) after the end of the humidification mode
