ABSTRACT:
Humidity control system for regulating the relative humidity of air which is forced through a spray painting booth. The humidity control system employs a water spray nozzle which atomizes water to quickly change the relative humidity and temperature of the ventilation air moving through the paint spray booth. A flow control valve which opens at a predetermined rate to control the water flow to the water spray nozzle in a manner which provides for an overdamped response to changes in the relative humidity level. The humidity control system further includes a motor for operating the flow valve, a controller for energizing the motor, and suitable sensors for providing feedback to the controller. The low predetermined rate at which the flow valve opens allows the water flow through the flow valve to be modulated by the length of time which the motor is energizes.
