Abstract
A bent coil for use in a ducted heating and cooling unit improves the heat exchange. The bent coil increases the overall surface area of the coil for a given duct volume, improving the heat exchange characteristics of the coil. The bent coil discharges air both longitudinally and laterally, eliminating the need for any additional ducting downstream from the coil to divert air toward the sides.
Description
- The present invention relates to heating and cooling systems, and more particularly to a ducted unit in such a system.
- Heating and cooling systems may incorporate a ducted
unit 100 having afan 102 and aflat coil 104 disposed inside a duct 106 (FIG. 1 ). Depending on the desired unit characteristics, the fan may be disposed either downstream with respect to the coil (i.e., a “draw through” architecture) or upstream with respect to the coil (i.e., a “blow through” architecture). As is know in the art, thefan 102 directs air through theduct 106 through thecoil 104 so that the air can be heated or cooled as it travels through thecoil 104. Thecoil 104 is designed to have a large surface area exposed to the air to optimize heat exchange with the air. - Normally, the
coil 104 has a flat profile and is disposed either vertically or at an incline with respect to a vertical axis in the duct 106 (FIG. 1 ). Note that regardless of whether thecoil 104 is vertical or inclined, the surface of theflat coil 104 delivers outlet air straight forward in both cases. While this coil structure is acceptable if air is discharged straight through the duct, it is less effective if the air is to be delivered at an angle (e.g., toward the sides). To discharge air from the sides, ducted units having a blow-through architecture often require one or moreadditional side ducts 108 downstream of thecoil 104 to redirect the air. However, the side ducts make installation of the system in, for example, a residence more complicated. Further, as can be seen inFIG. 1 , theside ducts 108 increase the overall system dimensions, making them impossible to install in small areas (e.g., corridors). - Also, because the
flat coil 104 is designed to discharge air only in a forward direction, air that is directed laterally into theside ducts 108 will experience pressure losses, reducing the overall efficiency of the ductedunit 100. - There is a desire for a compact structure that allows the ducted unit to discharge air laterally as well as forward without the efficiency losses encountered in currently known systems.
- There is a desire for a compact structure that allows the ducted unit to discharge air laterally as well as forward without the efficiency losses encountered in currently known systems. The present invention is directed to a bent coil for use in a ducted unit and a ducted unit incorporating a bent coil. The bent coil increases the overall surface area of the coil for a given duct volume, improving the heat exchange characteristics of the coil. The bent coil discharges air both longitudinally and laterally, eliminating the need for any additional ducting downstream from the coil to divert air toward the sides. As a result, air can be directed in multiple directions while keeping the overall dimensions of the ducted unit compact.
- A ducted unit incorporating the inventive bent coil according to one embodiment of the invention includes a fan and a coil that is arranged downstream from the fan, both of which are disposed in a duct. Air output from the front of the coil travels further downstream down the duct, while air diverted laterally by the coil is output through side discharge openings in the duct. The side discharge openings allow lateral air flow without requiring any additional ductwork.

FIGS. 2 and 3 illustrate two different embodiments of aninventive coil 200 that can be used in a ducted unit. Thecoil 200 is a bent coil rather than aflat coil 104, creating moredischarge surface area 201 than theflat coil 104 for a given duct volume. This increased surface area optimizes the available volume with theduct 106 and improves the coil's heat exchange characteristics by exposing more surface area to air. Thus, bending thecoil 200 makes it possible to place a larger coil within a given fixed duct volume.FIG. 2 shows thecoil 200 bent into a V-shape, whileFIG. 3 shows thecoil 200 bent into a curved shape. Of course, other non-linear coil configurations, such as a C-shape, M-shape, semi-circular shape, etc. are also possible without departing from the scope of the invention. Changing the profile of a vertical coil preserves the advantages of vertical coil structures generally (e.g., maintenance accessibility, water drainage during cooling operations, etc.) while still improving coil performance. - As can be seen in
FIGS. 2 and 3 , outlet air discharged through the coil will be directed laterally toward thesides 206 as well as toward thefront 204. By orienting anair discharge surface 201 so at least a portion of the surface is angled with respect to the normal, single longitudinal outlet air flow direction (as opposed to inclined with respect to a vertical axis of the duct), the outlet air flow will be multi-directional. Further, the bent shape of thecoil 200 increases the surface area of thecoil 200 for a given duct volume, increasing the heat exchange capabilities of thecoil 200. -
FIGS. 4 and 5 illustrate one embodiment of theinventive coil 200 in more detail. Note that the structure in thiscoil 200 can apply to any bent coil configuration. In this embodiment,vertical fins 208 in the coil, such as aluminum vertical fins, guide air flow toward both the longitudinal and lateral directions, thereby reducing pressure losses normally associated with lateral flow. In the embodiment shown inFIG. 4 , thecoil 200 includes two additionalvertical fins 208 to direct air perpendicular to the coil surface. The outlet air flow is thus divided into the twolateral flow paths 206 and thefront flow path 204. Of course, different numbers offins 208 may be included to direct air in different ways depending on the coil geometry and the discharge air directions. - Note that the bent profile of the
coil 200 ensures that a significant amount of surface area is exposed at different angles; for example, in the case of a V-shaped bent coil 200, portions of the front surface of thecoil 200 can be seen from the sides as well as from the front. This further ensures that any laterally-directedair 206 will not experience pressure or energy losses as it travels toward the sides of thecoil 200. - As shown in
FIG. 5 , thebent coil 200 also has a plurality of vertically-arrangedtubes 210. Thesetubes 210 are aligned vertically and staggered horizontally with respect to each other, allowing air to flow between thetubes 210 and be exposed to the maximum amount of surface area of thetubes 210. Note that in traditionalflat coils 104, the tubes in the coil tend to be aligned both horizontally and vertically when thecoil 104 is disposed at an incline with respect to a veridical axis in theduct 106. This allows air to flow past the tubes easily, but also causes tubes closer to the front of thecoil 200 to lie directly in front of tubes closer to the back of thecoil 200, thereby blocking much of the surface area of the tubes closer to the back. By keeping the coil vertical, theinventive bent coil 200 optimizes air distribution on thetubes 210 by taking full advantage of the staggering of tubes that prevent any one tube from falling within an aerodynamic shadow of another tube. -
FIGS. 2 and 3 illustrate a ductedunit 250 containing theinventive bent coil 200. The ductedunit 250 includes at least onefan 252 and aseparation wall 254 separating thefans 252 from thebent coil 200. Aduct 256 houses at least thecoil 200. As explained above, thebent coil 200 can directoutlet air 202 laterally 206 as well as toward thefront 204. As a result, the ductedunit 250 can includeside discharge openings 260 in theduct 256 to allow the laterally-directed air to escape. Note that theside discharge openings 260, in combination with thebent coil 200, eliminate the need for additional side ducts to direct air laterally. Because thebent coil 200 itself directs air laterally due to the fin structure described above and not due to additional ducting, air escaping theside discharge openings 260 does not experience any pressure losses due to the diversion. - The inventive coil structure therefore enables air delivery both in front of and to the sides of the coil while maximizing surface area in all directions to optimize heat exchange between the coil and the air flowing through the coil. Further, a ducted unit incorporating the inventive bent coil does not required additional, space-consuming side ducts or other equipment downstream from the coil to direct air laterally; instead, the ducted unit can simply include side openings to accommodate side ducts, relying upon the bent coil itself to direct the air through the openings. As a result, the inventive bent coil improves overall system efficiency while providing a compact, easily installable configuration.
