ABSTRACT:
A method for sizing a source capture system for an air cleaning system involves a determination of the maximum dissipated heat energy of an industrial process based upon a horsepower output of any motors used by the process, and a determination of the characteristics and maximum coolant pressure of any liquid coolant and the maximum terminal velocity of the ambient air surrounding the source capture system if the source capture system is at least partially open to ambient air. Using these factors, a minimum air flow velocity of air entering the source capture system is established. This minimum air flow velocity is then used to determine an effective cross-sectional size of the opening of the source capture system based upon a given air velocity volume within the source capture system. By utilizing this method with a preferred embodiment of a structure for the source capture system, it is possible to optimize the size of the openings in the source capture system.
