Abstract
A system for maintaining a desired air flow through a fume hood having a sash. The system comprises a mechanism for controlling air flow through the fume hood based on at least one gain. The system is also comprised of a mechanism for automatically tuning the gain connected to the controlling mechanism. Additionally, the system is comprised of a mechanism for manually inputting information to the tuning mechanism so the tuning mechanism automatically provides a desired gain to the controlling mechanism based on information received from the input mechanism. Additionally, the present invention pertains to a qualitative tuning system for a processor. The present invention also pertains to a method for controlling air flow through a fume hood with a sash. The method comprises the steps of providing information concerning flow of air through the fume hood to a processor. Then, there is the step of manually inputting information concerning gain into a qualitative tuning system connected to the processor. Next, there is the step of automatically producing an adjustment to the gain to the processor by the qualitative tuning system based on the information. Then, there is the step of controlling the flow of air through the fume hood with the processor based on the gain it receives from the qualitative tuning system. The present invention pertains to a method for qualitatively tuning a processor. The present invention additionally pertains to a system for controlling a fume hood having a sash with a face.
