湿器の構造によっても変化する。Some of the steam blown into the air is recondensed to form water droplets. The distance from the time when the water droplets re-evaporate and are absorbed in the air is determined by the humidification and absorption. It is called distance. If there is an obstacle within the range of the humidification absorption distance, dew condensation occurs on the obstacle due to collision of water droplets and vapor condensation, leading to a decrease in humidification efficiency and water leakage. The humidification absorption distance is affected by the humidification amount and the humidification air condition, and also varies depending on the humidifier structure.

きくなる等の問題がある。In the general steam humidifier shown in FIG. 5, the spray vapor loses the wind pressure of the ventilation air and cannot diffuse over a wide range, and flows in a layered manner from the vicinity of the steam outlet. As a result, the humidification absorption distance until it is absorbed into the ventilation air becomes longer, and the humidification efficiency decreases and the absorption into the ventilation air becomes insufficient, causing water leakage due to condensation of the supplied steam, or There is a problem that the installation space for installing the humidifier becomes large.

では製作コストが高くなるという問題がある。[0006] In order to shorten the humidification absorption distance, it is effective to diffuse and spray the blown steam over an area as large as possible. For this purpose, as shown in FIG. 6, the spray header 15 is branched and erected from the main header 14 through which the steam is passed, and the steam is sprayed from the outlet 16 of the spray header 15 into the air passage. . However, such a steam humidifier has a problem that the production cost is high.

湿吸収距離の短い高効率の加湿が行われる。[Function] Since the back surface of the resistor has a negative pressure, the spray water from the header rises along the resistor, and the spray water that has risen is partially diffused into the air from the back surface of the resistor by the air flow.
In addition, the eddy current generated at the side edge of the resistor diffuses in the width direction of the resistor and is scattered throughout the ventilation path, thereby performing highly efficient humidification with a short humidification absorption distance.
