<P>PROBLEM TO BE SOLVED: To provide a humidifying technology humidifying fast, preventing over humidifying, having good energy efficiency, free from maintenance, and requiring a low operation cost. <P>SOLUTION: A bubble generator is immersed in water stored in a water storage tank, and the water in the water storage tank is circulatingly supplied to the bubble generator to generate negative pressure in the bubble generator. Dry air is sucked into the bubble generator by the negative pressure, the sucked air is dispersed into the storage water in the water storage tank as bubbles by shearing force of water at a bubble discharging port of the bubble generator. The dry air in the bubbles in humidified, humidified air released from the bubbles arriving at a water surface due to a rise of the bubbles is discharged into the dry air, thereby humidifying the dry air. <P>COPYRIGHT: (C)2003,JPO |
