ABSTRACT An in duct humidification and evaporative cooling system for industrial and commercial buildings is disclosed. Air and water under pressure are utilized to atomize water into minute droplets which rapidly evaporate and raise the level of relative humidity while producing evaporative cooling. A first relative humidity sensor/transmitter produces a signal proportional to the relative humidity of return air, and a second relative humidity sensor/transmitter provides a signal proportional to the relative humidity of supply air. Preset receiver-controllers external to the duct receive the two signals and send them to a low signal selector which in turn sends the lower signal to a modulating water valve and to an electrical switch which opens a valve in the pressurized air supply line. A second electrical switch operatively connected in the air supply line opens a valve in the pressurized water supply line. Air and water from the two supply lines are delivered to in duct air and water manifolds and to spray heads on the air manifold to maintain automatically the required humidification and cooling parameters.
