Omni-directional face-and-bypass coil

A face-and-bypass coil apparatus comprising:

• a frame including a pair of side panels, at least one upper panel attached to said side panels, and at least one lower panel also attached to said side panels and located on a portion of said side panels removed from said upper panel;
• heating tubes pitched from between 1.degree. and 3.degree. with respect to the long axis of said side panels in order to avoid the accumulation of condensation within said heating tubes when said apparatus is mounted in a subsantially horizontal mode;
• a top header attached to one end of said heating tubes;
• a bottom header attached to the other end of said heating tubes;
• movable means for attaching said bottom header to said frame so that said header floats and is free to respond to thermal expansions and contractions of said heating tubes;
• fixed partition means connected to and extending between said upper and lower panels, said fixed partition means including a pair of flanges located on the leading and trailing edge of said partition means, said flanges facing towards said heating tubes and being slightly inclined towards each other;
• movable damper means including a plurality of U-shaped damper means having two arms on opposite sides thereof, said two arms being resiliently related to each other in such a way that they respectively impinge upon the flanges of said fixed partition means in a sliding fit thereby camming said resilient arms of said movable damper means away from each other and forming a resilient compression seal with respect to said fixed partitions to substantially completely block off air which otherwise might base over said heating tubes;
• mounting means for supporting said movable damper means so that said face-and-bypass coil can be installed in substantially any orientation ranging from vertical to horizontal with respect to gravity, said mounting means including linear ballbearing means attached to said frame and shaft means attached to said movable damper means, said shaft means being surrounded by said linear ballbearing means;
• means for moving said movable damper means;
• and,
• mixing and diverting baffle means attached to the trailing edge of said fixed partitions for improving the mix of bypass air with face-pass air and for equalizing system air flow volume with changes in damper opening position.
