Abstract: A compact fuel fired steam generating type humidifier. The apparatus uses a gaseous fuel as the prime source of heat to generate steam used to humidify air in the heating, ventilation and air conditioning of buildings. The humidifier may be a stand alone unit that disperses the steam into the space or the steam generated by the apparatus may be dispersed in forced air flow of the building heating system. The steam generating unit includes a water tank in which there is located a combustion chamber and a heat exchanger chamber for transferring the heat from the products of combustion to the water.

Abstract: The invention discloses a humidifying device which consists in a thermally conductive casing which is adapted and correctly dimensioned to fit over a conventional electrical radiator without preventing it from heating the ambiant air simultaneously. The casing is destined to be at least partially filled with water, and upon the radiator generating heat, the water temperature will gradually increase and water will evaporate into the ambiant air through outlets in the top of the casing due to the heat being conducted through the radiator and casing to the water. The water vapor outflow rate can be selectively adjusted by means of a pivotable heat deflector or alternately by adjusting the distance between the radiator and the casing. A sponge member filled with bactericide is inserted into the casing and is submerged in water.

One embodiment is adapted for placement over a floor outlet for heated air to evaporate water from the canal into the heated air to increase the humidity thereof. This embodiment may be above or just below floor level. Various forms of covers are associated with the units.

Abstract: A heat exchange humidifier for generation of steam-to-steam or fluid-to-steam humidity may include at least one steam tube in a heat exchanger array which may be coated with a non-stick surface such as tetrafluoroethylene (TEFLON.RTM.) coating or the like, to prevent the build-up of minerals. The steam tubes in the heat exchanger array are in a substantially layered configuration, each layer being offset and below the preceding upper layer, or in helical configuration. This organization of the tubes in the heat exchanger array maximizes convection currents in a fluid surrounding the steam tubes to minimize dead water films and maximize heat transfer from the steam or fluid inside of the tubes to the surrounding water, resulting in an overall increase in boil-off capacity for adding humidity to the air.

Abstract: A humidification system for a building utilizing a hot water heating tank within which is mounted a plenum chamber. Hot water from the tank is directed into the plenum chamber in controlled quantities and is agitated as controlled by a humidistat within the building to either vaporize the water within the plenum chamber or to force pressurized air through the plenum chamber to wet the air. The vaporized water or the wet air is directed from the plenum chamber into the air supply of the building. A water level control in the form of a float valve maintains the level of the water within the plenum chamber at a controlled level. The water may be vaporized by an electrical heater within the plenum chamber or the water may be aerated by air forced through the plenum chamber by a compressor, the humidistat activating the heater or the compressor.
