Abstract
A humidifier system includes a spray apparatus in a housing which sprays a mist of water droplets onto a mist eliminator to intercept the mist of water droplets. The mist of droplets is captured in a liquid phase by the mist eliminator and is substantially completely converted into a vapor phase in the form of increased humidity in the air stream. A humidity sensor located downstream of the mist eliminator senses the humidity of the stream of air. A controller controls the quantity of water sprayed in response to the humidity sensed to maintain a predetermined humidity in the humidified stream of air. A second humidifier includes a heater which creates a region of intense heat to instantaneously evaporate water mist directed thereon in a stream of air. In a third embodiment, water and pressurized air are simultaneously injected into a region of intense heat. The pressurized air rapidly expands within the region of intense heat and thereby adds energy to the system to ensure virtually complete evaporation of the water.
