PROBLEM TO BE SOLVED: To effectively perform humidification with the less amount of wind by providing a wind circuit for adsorbing outdoor air and a wind circuit for ventilation discharge to the outside of a room where adsorbent is passed, adsorbing water in outdoor air being introduced from the outside of the room, and at the same time by adsorbing the water in indoor air while indoor air is being evacuated. SOLUTION: On humidifying operation, outdoor air being taken from an outdoor intake vent 1 by a first blast means 5 and indoor air being taken from a ventilation intake vent 3 are passed by an adsorption means 2 and water in air is adsorbed and eliminated before evacuating it through an outdoor exhaust vent 4. The indoor air sucked from an indoor intake vent 6 by a second blast means 9 is passed through the adsorption means 2 where temperature is increased by reproduction, is heated by a heating means 7 after collecting the heat of the adsorption means 2, and is passed through the adsorption means 2 again. At this time, the water being adsorbed by the adsorption means 2 is desorbed and is discharged to the inside of a room through an indoor exhaust vent 8 as humidifying air containing a large amount of water. |
