PURPOSE:To improve an efficiency of atomization by a method wherein each of a air inlet port and a fog discharging port is arranged at a location where a high air speed in given between an air blower and a heat exchanger in opposition against a flow of air and further each of the ports is arranged at another location where a slow air speed is given in opposition against a direction of air. CONSTITUTION:An ultrasonic humidifier 1 is arranged outside a casing 2. Each of an air feeding pipe 28 and a fog discharging pipe 29 connected to the humidifier 1 is connected to an air feeding pipe 8 and a fog discharging pipe 9. The air feeding pipe 8 and the fog discharging pipe 9 form air inlet 8' and fog discharging port 9' slant cut at each of the extreme ends. The air inlet 8' is positioned between an air blower 3 and a heat exchanger 5 at an upper position having a high air speed in opposition to an air flow direction. On the other hand, the fog discharging port 9' is positioned between an air blower 3 and a heat exchanger at a lower position showing a slow air speed in opposition to a direction of air flow. A pressure difference in which the air inlet 8' shows a positive pressure and the fog outlet port 9' shows a negative pressure is generated between them and then fog generated at the ultrasonic humidifier 1 is efficiently injected from the fog outlet 9'. |
