摘要： A system for directing air flow in a fume hood having a sash includes a mechanism for producing an output control signal corresponding to a desired flow of air through the sash of the fume hood. The producing mechanism includes a CPU which actively produces the output control signal and is disposed in fluid communication with the fume hood. The system also includes a mechanism for controlling air flow through the sash of the fume hood corresponding to the output control signal. The controlling mechanism is connected to the producing mechanism to receive the output control signal and includes a CPU which actively produces a drive signal for operating the controlling mechanism corresponding to the output control signal. A corresponding method for controlling the air flow in a fume hood is also provided. Also a corresponding system for maintaining a desired relationship regarding air between a first room and a second room separated from but connected to the first room by a wall with an interface through which air can pass when the interface is in an open state is provided.
