ABSTRACT:
The humidification device includes a tube formed of gas permeable material connected to a water source by a tube formed of material that is substantially impermeable to water. The gas permeable tube permits water to evaporate through the tube wall and is thus an evaporation tube. The evaporation tube is disposed in a chamber that is to be humidified. As water evaporates from the evaporation tube, the humidity in the chamber builds up to a maximum level. At the maximum humidity level evaporation of water from the evaporation tube ceases. When the humidity level in the chamber drops below the maximum level, evaporation of water from the evaporation tube resumes to restore the humidity in the chamber to its maximum level. Water flow from the water source replaces evaporated water from the evaporation tube. The humidification device is thus self-regulating and does not require any water flow regulating devices. One or more water flow tubes can be connected to the evaporation tube from a water source.
