Description

  • The present invention relates to air handling units and in particular to panel constructions and panel support arrangements for air handling units.
  • An air handling unit typically comprises a casing made up from a number of thermally insulating panels which are joined together into a desired shape. Typically such panels comprise inner and outer sheet metal skins which sandwich an insulating material between them.
  • The panels are connected together by mounting them to supports which incorporate elastomeric seals arranged to prevent leakage of air between the panel and support.
  • Various panel constructions and panel mounting arrangements are described in US-A-5285609 , GB-A-842939 , US-A-445262 , US-A-3267626 , US-A-4326365 , US-A-3540116 , EP-A-0468597 , US-A-4782637 and US-B1-6350000 .
  • The present invention seeks to provide an improved panel construction and mounting arrangement.
  • The present invention provides an apparatus as claimed in claim 1. Two recesses are provided on adjacent faces of one corner, so as to form an L-shaped recess at that corner, thus allowing panels to be connected together in different orientations with the same connector.
  • A seal, typically 0.2 to 0.5mm thick may be positioned between the flange and support to provide airtightness.
  • Preferably the panel construction comprises first and second sheet metal members and thermal insulation material retained between the sheet metal members, peripheral portions of said sheet metal members being joined together at a peripheral flange, wherein the peripheral portion of the second sheet metal member is wrapped around the peripheral portion of the first sheet metal member so as to trap the peripheral portion of the first sheet metal member between two layers of the second sheet metal member.
  • In this construction, the peripheral portion of one sheet member is sandwiched between two thicknesses of the other sheet material. This arrangement gives a particularly strong construction which is capable of withstanding substantial pressures and forces.
  • Preferably the first sheet metal member is channel-like in cross section order to receive the insulating material, and the second sheet metal member substantially planar, closing the open face of the channel.
  • The insulating material may be a polymeric foam, rockwool, fibreglass or any suitable material depending on the particular mechanical and/or thermally insulating properties required of the panel.
  • Depending on the properties required, the sheet metal is preferably less than 1.5mm thick. For example in a panel which is required to have good acoustic insulation properties, it may be up to 1.25mm thick. For thermal insulation properties, however, a thinner material is desirable.
  • A thickness which has been found to give a good combination of strength and low heat conduction is 0.8mm. However, thinner material for example 0.6mm thick, may be used if strength is less of a requirement or if the panel is filled with a relatively strong insulation material such as a foam.
  • Preferably the panel walls are spaced apart by between 50 and 100mm. Preferably, however, the walls are spaced apart by 60mm.
  • The peripheral flange of the panel may be provided with holes extending therethrough to receive a fastener for fastening the panel to a support.
  • Preferably the fastener is a self-tapping screw which taps into the receiving surface. However, other fasteners, for example bolts and so on, may be envisaged.
  • Preferably the support or connecting member is a hollow body. Most preferably it is a roll formed and welded body. For strength purposes it is preferably at least 1mm thick
  • The support or connecting member comprises engagement or receiving surfaces arranged at the desired angle to each other. Preferably the engagement surfaces are arranged at right angles to allow panels to be connected at right angles.
  • The fastener may be countersunk into the peripheral flange of the panel where it is desired to position the flange of one panel adjacent the wall of an adjacent panel. Alternatively, the fastener may stand proud of the flange.
  • One problem which arises with connections between panels is that of transmission of heat to the outside of the unit through the fastener. This potentially gives a higher spot temperature on the outside leading to the unit being given a lower thermal bridging rating.
  • This problem is overcome in accordance with a preferred aspect of this invention by providing a heat distribution member arranged in contact with the fastener and acting to distribute heat from the fastener over a larger area, thereby reducing the spot temperature.
  • Preferably the heat distribution member is a cap or the like which fits over the head of the fastener to cover the head of the fastener from view. Most preferably it clips over the fastener head. To this end it may have a plurality of resilient tangs which clip under the head of the fastener when the cap is placed in position.
  • Preferably the heat distribution member fits over a plurality of fasteners, and most preferably it is in the form of a strip having spaced apart formations for engaging the respective fasteners. The strip is preferably sheet steel, most preferably between 0.6 and 1mm thick, most preferably 0.8mm thick.
  • Preferably the strip is generally rectangular in cross section with spaced inner and outer walls, the inner wall having formations for engaging the fasteners and the outer wall covering the fastener head.
  • The panel connections may allow the panels to be separated. The side wall of the connector may be provided with a recess to receive a seal which, when assembled together with a complementary connector, provides airtightness between the panels.
  • A particularly preferred structure may be constructed in accordance with the invention comprising panels arranged parallel to one another and spaced apart by a further panel or panels.
  • A preferred embodiment of the invention will now be described by way of example only with reference to the accompanying drawings in which:
    • Figure 1 shows a cross-section through a wall construction;
    • Figure 2 shows a first detail of the construction of Figure 1;
    • Figure 3 shows a second detail of the construction of Figure 1;
    • Figure 4 shows a detail of Figure 3; and
    • Figure 5 shows a corner joint for connecting connectors together.
  • The connecting members 16, 18, 24 in fig. 1 and 3 are not covered by the claims and are merely presented as background art or examples, which are useful for understanding the invention.
  • With reference to Figure 1, a wall construction 2 comprises a number of thermally insulating panels 4, 6, 8, 10, 12, 14 joined together by connectors or connecting members 16,18,20,22,24.
  • The top panels 4,6,8 and side panel 10 are of the same construction. The floor panels 12,14 are of the same construction as each other, but differ in detail from the top and side panels 4,6,8,10. However, the construction of each panel is substantially the same and this will be described with reference to panel 12.
  • The panel 12 comprises a first sheet metal member 26 which is generally channel shaped and which is formed with a peripheral edge or portion 28 (see Figure 2). This first member 26 receives a body of insulating material 29.
  • The nature of the insulating material may vary from panel to panel. It may, for example in the floor panels 12,14, be a foam material giving greater strength. However, in the top and side panels 4,6,8,10 it may be a weaker material such as a rock wool or glass wool insulating material.
  • The panel member 12 further comprises a second sheet metal member 30. The second member 30 is substantially planar and it is formed with a turned-over peripheral edge or portion 32. This edge wraps around the edge 28 of the first sheet metal member 26 so as to trap the edge 28 inside the edge 32. This forms a triple thickness panel mounting flange 34.
  • The edge 28 and folded edge 32 are provided with aligned openings 36, 38, 40 to receive a self-tapping fastener 42 (see Figure 2). The opening 40 through the upper surface 44 of the edge 32 is larger than those 36, 38 in the edge 28 and lower surface 46 of the edge 32 to allow the head of the fastener 42 to lie flush with the upper surface of the sheet 30.
  • In the particular embodiment described, the sheet metal members 26,30 are formed from 0.8 mm galvanized steel which is suitably bent to the appropriate shape. However other materials, such as stainless steel may be used. The spacing between the panel walls is 60mm giving a total panel thickness of 61.6mm.
  • The flange 34 is constructed in the same manner at both sides of the panel 12.
  • As stated above, the top and side wall panels 4,6,8,10 are constructed in a generally similar manner, but with different lengths. A further difference is in the arrangement of the openings through the mounting flange 34, as shown in Figure 3.
  • In that arrangement, the opening 48 through the top surface of the flange 34 is smaller than the underlying openings 52, 54 in the flange 34 so as to receive a non-countersunk fastener 56. Again, the construction of the flange 34 is the same at both ends of the panel.
  • The mechanism by which the panels are joined together with now be described with reference to Figures 2 and 3.
  • It will be seen that there are a number of different joining arrangements disclosed. Dealing firstly with the corner connectors 20,22, one of these connectors 22 is shown in greater detail in Figure 2.
  • Each connector 22 comprises a roll formed and welded metal body 58 with a wall thickness of 1mm. It comprises four recesses 60,62,64,66 for receiving the mounting flanges 34 of the various panels. The external recesses 60,62 are deeper than the internal recesses 64,66 so as to accommodate the head of a non-countersunk fastener 68.
  • The floor of each recess 60,62,64,66 provides a engagement or receiving surface against which the inner surface of each panel mounting flange 34 will be clamped by a respective fastener 42,68 via a seal strip 70, typically 0.2 to 0.5mm thick. This provides for airtightness in the connection.
  • A further connector 18 is shown in Figure 3. In this embodiment, the connector comprises a rectangular section roll formed and welded body 71, also with a wall thickness of 1 mm, which receives two screw fasteners 56, as shown.
  • In this embodiment a pair of heat distribution strips 72 are provided over the heads of the fasteners 56 in order to distribute any heat coming through the fasteners and indeed the connection flanges over a larger area to prevent higher spot temperatures occurring.
  • Each strip 72 comprises an inner wall 76 and an outer wall 78 which covers the fasteners 56. The inner wall 76 is provided with spaced apart clips 80 with spring tangs 82 which clip over the heads of the fasteners 56 to retain the strip in position.
  • Yet further connectors 16,24 are also disclosed in Figure 1. Each of these connectors comprises two rectangular bodies 84, each having one panel joined thereto by respective fasteners 42, 56. One side of each body 84 comprises a recess 86 which faces the recess 86 of the opposed body 84. A generally rectangular seal member 88 is received in the cavity defined by the aligned recesses 86. This arrangement allows the panels to be disconnected from one another in a direction perpendicular to their length.
  • It will be seen that the assembled panels have smooth internal and external surfaces.
  • It has been found that the above constructions provides exceptional thermal, leakage and mechanical properties. In particular they provide thermal insulation to class T2 and class TB2 of EN 1886, air leakage to class L2 of EN1886 and pressure resistance to class D1 and D2 of EN 1886.
  • The panels can be joined together in substantial lengths, for example from unit dimensions 600 x 300 mm to 3000 x 4500 mm and can be assembled in varying combinations and sizes.
  • Different shaped spaces may easily be defined by the panels, for example a rectangular space as shown in Figure 1, with panels arranged parallel to one another and connected by one or more other panels.
  • A corner joint 90, for joining together corner connectors 20 to form a three dimensional frame is shown in Figure 5.
  • Here three individual connectors 20 are joined by a member 92 which has three projections 94 which extend into the internal space of the connectors to hold them in position. Panels can then be fitted onto the respective connectors as described above.
