PROBLEM TO BE SOLVED: To prevent the contamination of air even when heating operation is effected for a long period of time in a closed room by a method wherein an air flow passage for sucking humidity and a flow passage for humidifier for an air conditioner equipped with a no water-supply humidifier are permitted to be communicated with each other. SOLUTION: An air flow passage for sucking humidity is constituted of a duct 15, a humidifying treatment chamber 26, a fan 12 for sucking humidity and another duct 16. An air flow passage for humidifying is constituted of the other duct 19, the humidifying treatment chamber 26, a fan 13 for humidifying and other duct 20. A damper 14 for ventilation is positioned at the center of widthwise direction of the humidifying treatment chamber 26 and when the damper becomes an opened condition, air, flowing through the duct 15 is discharged into a room from an air discharging port 22 for humidifying through the fan 13 for humidifying and the duct 20 as shown by an arrow sign 25 in a diagram. When the damper becomes a closed condition, air, flowing through the duct 15, is discharged to the outside of the room through the fan 12 for humidifying and the duct 16. Ventilating operation can be switched into humidifying operation easily by operating the opening and closing of the damper 14 for ventilation whereby the contamination of air in the room can be restrained. |
