Title: Method for control of air relative humidity with reduced energy usage

Abstract: A method for precisely controlling air dry bulb temperature and relative humidity in which the dry bulb temperature is sensed so that variations therefrom produced by cooling of the air in a spray water curtain are used to control the spray water curtain heat exchange area. Additionally, the dew point temperature is sensed and used for controlling the temperature of the spray water and hence the relative humidity in the air at a desired dry bulb temperature.
