Abstract:
An air handling system for an air treatment system comprising:a plurality of air treatment sections to condition a volume of air flow therethrough,a plurality of air bypass sections respectively positioned adjacent said air treatment section to provide an air flow path for air to bypass said air treatment sections,a plurality of moveable panel members selectively moveable between first positions in front of said air treatment sections to block the flow of air to said air treatment sections to second positions to block the flow of air through said bypass sections,whereby selected positioning of said moveable panel members between said first and second positions varies the volume of air flowing through said air treatment sections and said bypass sections to selectively vary the volume of air to be treated in said air treatment sections;and a perforated plate means disposed upstream of said air flow direction in front of said air treatment section and behind said plurality of moveable panel members;said perforated plate means having both perforated and unperforated sections located upstream of said air treatment means and perforated sections upstream of said bypass sections,said plurality of moveable panel members being arranged to align in their first position with the perforated sections of the plate means upstream of said air treatment means and in their second position to align with the unperforated sections of the plate means upstream of said air treatment means and with the perforated section of the plate means upstream of said bypass section.
