Definitions

  • This invention relates generally to a panel for use in an air handling unit that forms a thermal barrier to limit the flow of energy through the panel.
  • the outer casing of the unit will "sweat” due to condensation of water vapor in the relatively hot outside air upon contact with the casing.
  • the moisture so developed will run off the unit onto the floor or onto equipment contained in the unconditioned space. Such run off creates a safety hazard for people working in the area and can damage the equipment.
  • a further object of the present invention is to limit the loss of energy through the walls of a duct carrying conditioned air.
  • a still further object of the present invention is to provide an improved panel for use in an air handling unit.
  • Another object of the present invention is to provide a structural panel for use in an air handling unit that has a relatively high R value.
  • Yet another object of the present invention is to prevent ducts of an air handling unit from sweating when carrying conditioned air.
  • a panel suitable for use in an air handling duct for carrying air along an enclosed path of travel includes a rectangular frame made of a material having a relatively high R value.
  • the frame is closed by a top cover and a bottom cover so that a cavity is established within the panel.
  • the cavity is filled with a curable material that sets inside the panel to bond the walls of the frame together and to bond the covers to the frame.
  • a bulb seal having high insulation characteristics extending along the length of one edge of adjoining panels so that energy transmission is further inhibited.
  • Fig. 1 is a perspective view showing a section of ductwork for conducting air along a desired flow path with a panel shown removed from the support frame of the ductwork;
  • Fig. 2 is an enlarged perspective view of a panel employed to enclose the support frame of the ductwork illustrated in Fig. 1;
  • Fig. 3 is an exploded view illustrating the panel frame and covers
  • Fig. 4 is an enlarged sectional view of the panel frame taken along line 4-4 in Fig. 3;
  • Fig. 5 is an enlarged sectional view of the panel assembly taken along lines 5-5 in Fig. 2;
  • Fig. 6 is an enlarged partial view showing a corner section of the ductwork skeleton with one panel removed from the duct work;
  • Fig. 7 is a view similar to Fig. 6 showing the panel locked to the ductwork skeleton
  • Fig. 8 is an enlarged view showing the latching mechanism for locking a panel to the ductwork skeleton in a retracted position
  • Fig. 9 is similar to Fig. 8 showing the latching mechanism in a raised locking position
  • Fig. 10 is an enlarged sectional view of the panel assembly taken along the lines 10-10 in Fig. 1;
  • Fig. 11 is a top schematic illustration of the panel assembly in the left-most region of the ductwork shown in Fig. 1 with the panels oriented in a side-by-side arrangement along the ductwork frame;
  • Fig. 12 is a schematic illustration similar to that shown in Fig. 11 with one of the panels hingedly mounted to the frame and rotatably extending in an open position relative to the frame; and
  • Fig. 13 is a schematic illustration similar to Fig. 11 showing an unhinged panel removeably positioned away from the frame.
  • FIG. 1 there is illustrated a section of an air handling unit (AHU), generally referenced 10, that employs wall panels 12 embodying the teachings of the present invention.
  • the . air handling unit is composed of a series of rectangular shaped modules each of which possess a superstructure including a pair of rectangular, planar end frames 13 and 14 that are connected at the corners by a pair of horizontally disposed upper beams 15 and a pair of horizontally disposed lower beams 16.
  • Each end frame includes a pair of opposed side rails 17 and 18 and an upper rail 20 and a lower rail 21.
  • the rails and the beams are retained slidably in corner pieces 23. The rails and the beams in assembly thus establish an open skeleton having rectangular openings.
  • wall panels embodying the teachings of the present invention can be placed in the skeleton openings to close the AHU sections.
  • Each panel is constructed so that it has an extremely high insulation value, thus greatly impeding the flow of heat into or out of the unit which, in turn, prevents the unit from sweating.
  • each panel 12 includes a rectangular frame 25 having a pair of opposed side walls 27 and 28 and a pair of opposed end walls 29 and 30.
  • Each wall contains mitered ends so that the walls can be brought together to form right angle corners.
  • Each wall is molded of a plastic material having a high insulation value and low thermal conductivity.
  • each wall contains a vertically disposed wall partition 31 having a rectangular shaped recess 32 formed centrally therein that extends along the length of the partition.
  • the recess 32 is inwardly disposed with reference to the outer surface of the partition 31.
  • An upper tab 33 and a lower tab 34 are integrally molded on the inside of the partition 31 on either side of the recess 32.
  • the tabs 33, 34 extend along the length of the wall.
  • the tabs 33, 34 run parallel to the partition 31 and coact therewith to form narrow channels 35 and 36.
  • the upper channel 35 opens towards the top of the wall while the lower channel 36 opens toward the bottom of the wall.
  • a flange 38 which is integral with the wall partition 31, runs along the top edge of the partition 31.
  • the flange 38 extends outwardly from the wall partition 31 and forms an angle that is slightly less than 90° with the partition 31 so that the flange 38 extends downwardly at a slight angle from the top edge of the partition.
  • a top cover 40 and a bottom cover 41 are used to close the frame and create a cavity inside the panel.
  • Each cover 40, 41 contains an inwardly directed skirt 45 that depends downwardly from the cover and extends around the entire periphery of the cover.
  • the skirts 45 are inserted into the upper and lower channels that encircle the panel frame.
  • a curable foam 43 is injected into the cavity to entirely fill the cavity with the foam. When the foam cures, it bonds the frame walls together in abating contact and bonds the covers to the frame.
  • the curable foam is a polyurethane material which like the panel frame walls has a high insulation value.
  • Each panel is sized so that the panel frame can be slipped into an opening in one of the unit sections.
  • a close sliding fit is provided between panel frame walls and the side rails and upper and lower beams that form the receiving opening.
  • the flange 38 that surrounds the panel frame is compressed against the outer surfaces of the rails and beams forming the opening.
  • compressible hollow seals 50 are preferably mounted around the panel receiving opening. At panel closure, the lower cover 41 of the panel compresses the seals as shown in Fig. 7 to prevent air inside the unit from escaping around the panel.
  • Each latching mechanism includes a cylindrical tumbler 62 that is retatchably contained within the tube 63.
  • the tumbler contains an outer flange 64 (see Figs. 8 and 9) that has a six sided slot 65 that passes inwardly through the flange.
  • An Allen wrench 67 is insertable into the slot and is used to turn the tumbler between an open position and a locking position.
  • An elongated arm 70 is secured to the tumbler that is arranged to pass upwardly through a slotted hole 69 in the containing tube as the tumbler is turned from an open position as illustrated in Fig.8 to a locking position as illustrated in Fig.9.
  • the arm 70 is arranged to pass into the recess 32 surrounding the panel frame and to force the panel into sealing contact against the seals 50 surrounding the panel receiving opening as shown in Fig.7.
  • at least one latching mechanism is employed to engage each of the walls making up the panel frame 25.
  • each of the panels is essentially identical to the panels previously described, in addition, each peripheral wall of the panel facing the peripheral wall of the adjacent panel possesses a generally U-shaped groove 90 associated with the channel.
  • each groove 90 extends generally parallel to an associated one of the channels in the wall and is disposed peripherally outwardly from the associated channel.
  • the depth of each groove 90 is substantially shorter than the depth of the associated channel, approximately one-quarter to one-half of the depth of the associated channel.
  • each groove 90 is formed by integrally molding the groove 90 with the wall.
  • At least one of the panels includes a substantially L-shaped bar 92 having a first leg 94 adapted to abut an associated one of the channels and to extend into the associated groove 90.

Abstract

Cette invention concerne un panneau (12) qui s'utilise dans un conduit d'air pour climatisation. Ce panneau comprend un cadre de forme rectangulaire (25) fait dans un matériau ayant un coefficient R relativement élevé. Le cadre (25) est fermé par un couvercle supérieur (40) et un couvercle inférieur (41) qui définissent une cavité interne. Cette cavité est remplie d'un matériau durcissable qui prend dans le panneau et colle les parois du cadre les unes aux autres et donc les couvercles au cadre. Un joint à vide central (50, 98) aux caractéristiques isolantes élevées est disposé le long d'un bord de panneaux adjacents, ce qui diminue encore les pertes d'énergie.
