Abstract:
1. A method for humidifying a habitable space comprising the steps of: providing a water vapor-containing flue gas having a first water vapor partial pressure generated by one of a residential furnace and a commercial furnace to a flue gas side of a porous liquid water transport membrane; providing habitable space air having a second water vapor partial pressure less than said first water vapor partial pressure to a habitable space air side of said porous liquid water transport membrane opposite said flue gas side in an amount sufficient to provide a habitable space air to flue gas volume flow rate ratio of at least 8.3:1; condensing at least a portion of said water vapor in said flue gas in an interior of said porous liquid water transport membrane, forming liquid water in said interior in an amount sufficient to substantially prevent all gaseous components in said flue gas from passing through said porous liquid water transport membrane to said habitable space air side; passing said liquid water to said habitable space air side of said liquid water transport membrane; evaporating said liquid water on said habitable space air side into said habitable space air, producing humidified habitable space air; and providing said humidified habitable space air to said habitable space.
