Abstract
An air flow pressure compensator system maintains substantially constants air flow within a clothes dryer system and adjusts the speed of one or more exhaust fans by monitoring one or more sensors/transmitters positioned in one or more exhaust ducts and/or one or more incoming air ducts. The system includes a compensator controller; a variable frequency drive electrically coupled to the compensator controller; and an anemometer and/or a differential pressure sensor/transmitter electrically coupled to the compensator controller that allow for real-time monitoring and system adjusting, which improve clothing drying time and dryer efficiency.
