Abstract
A bent coil used in a ducted heating and cooling unit improves heat exchange. The bent coil increases the overall surface area of the coil for a given duct volume. Openings in a separation wall focus an air flow from fans towards the bent coil. Fins direct the air through the bent coil, and a net removes turbulence from the air flow prior to moving through the bent coil. The bent coil discharges air both longitudinally and laterally, eliminating the need for any additional ducting downstream from the bent coil to divert air toward the sides.
