ABSTRACT:
An absolute humidity sensor and a thermostat are located in an area where humidity and temperature are to be controlled. Air from this area is circulated through an air washer having a dry bulb temperature sensor at its discharge. Output signals from the absolute humidity and dry bulb temperature sensors are utilized to operate the air washer to control the moisture content of its discharge air. The thermostat operates a bypass damper to control the amount of circulating air which passes through the washer.
