Abstract: A system and method for controlling the enivronment toward obtaining a prespecified absolute humidity within a substantially enclosed and pressurized work area such as a textile manufacturing plant is disclosed. A plurality of condition sensing signal generating sensors are positioned within the work area. A first signal generator sensor is responsive to sensed relative humidity, a second signal generator sensor is responsive to sensed dry bulb temperature, and a third signal generator sensor is responsive to sensed barometric pressure. An air washer operatively communicates with the work area for conditioning the air enclosed within the work area. A microprocessor operatively connects the air washer and the condition sensing sensors for receiving and correlating within the microprocessor the received sensed values so as to repeatedly adjust the operation of the air washer and condition the air within the work area toward obtaining the predetermined absolute humidity.
