according to the invention.
Referring to the drawings and initially to Figs. 1 to 18 thereof, there is illustrated an air handling system according to the invention and indicated generally by the reference numeral 1. The air handling system 1 comprises an inlet housing 2 including a fan unit 3 and an outlet housing 4 connected to the inlet housing 2. The inlet housing 2 up to and including the fan unit 3 is a negative pressure section through which air is drawn through by the fan unit 3. The outlet housing 4 is a positive pressure section through which air is driven by the fan unit 3.
The air handling unit comprises a number of air handling components including, in this case, an inlet air damper 6, a filter 7, an air cooling unit 8, an air heating unit 9 and a bag filter 10 on the downstream side of the fan 3. For ease of control the fan 3 is preferably operated by a motor 12 which is connected by means of a belt and pulley drive (not shown) to the fan 3. The air handling system 1 includes access doors at appropriate locations in the system. In this case, there is an inlet access door 12 upstream of the filter 7 through which a user gains access for cleaning the filter 7. An outlet access door 13 is provided downstream of the fan 3 for maintenance access to the fan and to the bag filter 10.
If space permits, access doors are positioned at other locations in the system to allow ease of access for maintenance of each of the air handling components in the system.
In more detail, and referring particularly to Figs. 2 to 5, 10 and 11, the inlet housing 2 comprises an inlet framework 15 which is illustrated in detail in Fig 2, and panels 16 (see
Fig. 10) sealed to the inlet framework to prevent ingress of air and/or particles of dust and dirt through joints between the panels 16 and the frame members of the inlet framework 15.
The inlet framework 15 comprises two pairs of upright inlet corner posts 20 at opposite ends of the framework 15. Upper 21 and lower 22 longitudinal inlet frame members extend between the inlet corner posts 20. Upper 23 and lower 24 transverse inlet frame members extend between the inlet corner posts 20 and the upper and lower longitudinal inlet frame members 21, 22 respectively.
The corner post 20, longitudinal inlet frame members 21, 22 and transverse frame members 23, 24 are interconnected by an inlet corner connector 30 which is shown in detail in Fig. 12.
The inlet corner connector 30 comprises a body member 31 having three spigot-like members 32, 33, 34 projecting therefrom for engagement with respective sockets defined by a corner post 20, an adjacent longitudinal frame member 21, 22 and an adjacent transverse frame member 23, 24.
The inlet corner posts 20 and longitudinal and transverse inlet frame members 21, 22, 23, 24 are extruded from a common die and each has a longitudinally extending outer face 40, a transversely extending outer face 41, a longitudinally extending inner face 42 and a transversely extending inner face 43. It will be appreciated that in this context the terms longitudinal and transverse are relative and the designation of longitudinal and transverse faces of the members will depend on their relative position in the framework. The inner faces 42, 43 of the corner posts 20 and frame members 21, 22, 23 and 24 each have sidewardly extending flanges 45 against which the panels 16 are sealed in use to prevent ingress of air and/or particles of dirt through the joint between the panels 16, the inlet corner posts 20, and the inlet longitudinal transverse frame members 21, 22, 23, 24.The arrangement will be particularly apparent from Fig.
10.
A plurality of intermediate frame members 47 extend between the upper and lower longitudinal frame members 21, 22 respectively. The intermediate inlet frame members 47 are extruded from a common die and each has longitudinally extending inner and outer faces 48, 49. The inner faces 48 have sidewardly extending flange means 46 against which the panels 16 are sealed to prevent ingress of air and/or particles of dirt and dust through the joint between the inlet intermediate frame members 47 and the panels 16.
Referring particularly to Fig. 4 there is illustrated the jointing between an intermediate frame member 47 and the upper longitudinal frame member 21. The flanges 46 of the intermediate frame member 47 are cut-away to accommodate the depending flange 45 of the longitudinal frame member 21 and a box insert piece 47A is inserted into the channel of the intermediate frame member 47 for receiving connecting bolts inserted through the intermediate member 47 and flange 45.
In more detail and referring to Figs. 7 to 9, 11 and 12, the outlet housing 4 comprises an outlet framework 50 and panels 16 sealed to the outlet framework 50 to prevent egress of air through the joint between the panels 16 and the outlet framework 50.
The outlet framework 50 comprises two pairs of upright outlet corner posts 51 at opposed ends of the framework 50. Upper and lower longitudinal outlet frame members 52, 53 extend between the outlet corner posts 51. Upper 54 and lower 55 transverse outlet frame members also extend between the outlet corner posts 51. As with the inlet framework 15 described above, outlet corner connectors 30 are provided at the top and bottom of each outlet corner post 51 and each outlet corner connector 30 interconnects the outlet corner post 51 to adjacent longitudinal and transverse outlet frame members 51, 52, 53, 54, 55.
The outlet corner posts 51 and longitudinal and transverse outlet frame members 52, 53, 54, 55 each have a longitudinally extending outer face 57, a transversely extending outer face 58, a longitudinally extending inner face 59 and a transversely extending inner face 60. In this case the outer faces 57, 58 have sidewardly extending flanges 61 against which the panels 16 are sealed in use, as illustrated in Fig.
11, to prevent the egress of air through the joint between the panels 16 and the outer corner posts and the outer longitudinal and transverse frame members. As mentioned above, the designation of longitudinal and transverse faces depends on the orientation of the frame member in the framework.
A plurality of intermediate outlet frame members 65 extend between the longitudinal outlet frame members 52, 53. The intermediate outlet frame members 6 are extruded from a common die for the inlet intermediate frame members 47. The outlet frame members 65 are again extruded from a common die and are provided with longitudinally extending inner and outer faces 67, 68 and the outer faces 68 are provided with sidewardly extending flange means 69 against which the panels 16 are sealed to prevent egress of air through the joint between the outlet intermediate frame members and the panels 16.
Referring particularly to Fig. 8 there is illustrated the jointing between an intermediate frame member 65 and the upper longitudinal frame member 52. The flanges 69 of the intermediate frame member 65 are cut-away to accommodate the depending flange 61 of the longitudinal frame member 52. A box insert piece 65A is inserted into the channel of the intermediate frame member 65 for receiving connecting bolts inserted through the intermediate member 65 and flange 61.
Each of the panels 16 is of double skin construction and comprises an inner skin 70, which is typically of galvanised steel material and an outer skin 71 which is typically also of galvanised steel material but in this case is preferably coated with a coloured hard wearing material. The space between the inner and outer skins 70, 71 is filled with fibre glass material 72 for thermal and acoustic insulation. The fibre glass material typically has a density of approximately 48Kg/M3.
Referring in particular to Figs. 13 and 14, the inlet access door 12 is illustrated in more detail. w The door 12 is hingedly mounted by a full length piano stainless steel hinge 75 to an inlet intermediate frame member 47 to open outwardly as illustrated in Fig. 14. A sealing strip 76 of flexible material is mounted to the marginal edges of the door 12 and/or frame member 47 for engagement, on closing, against the flanges 46 of the intermediate frame members 47. The door 12 typically includes a viewing window 78 of reinforced glass.
Referring to Figs. 15 and 16, the outlet or positive pressure access door 13 is illustrated in more detail. The door 13 is of the same construction as the inlet door 12 and like parts are assigned the same reference numerals. In this case, the door 13 is arranged to open inwardly for positive sealing of the door in position to prevent egress of air downstream of the fan.
Referring in particular to Fig. 17 there is illustrated an outlet or positive pressure glanding detail used in the air handling system of the invention. A hole is first drilled through the intermediate frame member 65 as illustrated and a two part glanding member is led through the hole from opposite sides and is sealingly engaged to provide a sealed path for an electrical cable 81 or the like
Referring to Fig. 18, there is illustrated a sleeve unit penetration detail of the air handling system. An opening is drilled through the panel 16 for receiving a pipe 85 or the like. An aluminium sleeve 86 is inserted through the hole from the inside and the sleeve is provided with an inner collar 87 which is engaged with the inside surface of the panel 16. An outer seal 87 is provided between the pipe 85, the sleeve 86 and the panel 16 for sealing engagement of the pipe 85.A silicone seal is provided between the neoprene seal 87 and the sleeve 86 for positive sealing engagement.
The arrangement is such that not only is the ingress of dirt and air through the hole in the panel prevented but also condensate forming on the pipe 85 is prevented from entering the panel 16 and thus the panel is effectively protected from moisture and dirt ingress.
Referring to Fig. 19 there is illustrated another air handling system according to the invention. The system is similar to that described above and includes a supply fan 90 driven by a motor 91 which delivers supply air through a humidifier 92, an attenuator 93 and bag filter 94 to a clean room area. The air feed for the fan 90 is made up from return air from the clean room which is drawn through a return attenuator 95 and through a bag filter 96 by a return fan 97 driven by a motor 98. The return air is mixed with fresh air which is delivered into a mixing box 99 through a fresh air damper 100. A spill air damper 101 and the circulating air damper 102 are also provided. The dampers 100, 101, 102 are opened or closed to a pre-determined position to obtain a desired mix of fresh and return air which is delivered from the mixing box 99 through a panel filter 105. The air then passes through a pre-heat coil 106, a cooling coil 107 and a heat recovery coil 108.
Many combinations and variations of the various components of the air handling system will be readily apparent.
The air handling system is produced by first automatically producing a working drawing from user inputs of the specifications required of the air handling unit. The working drawing is then reviewed and, if necessary modified, again in response to user inputs. A cut list of frame and panel members required to produce the framework of the air handling system is then automatically produced. This cut list is used for controlling and programming the cutting of stock, frame and corner members to a required length as determined by the cut list. Similarly, inner and outer panel members are cut to size as determined by the cut list. The panels are assembled from the inner and outer panel members and a block of insulating material is provided therebetween.
In addition to generating a cut list, a plurality of labels containing codes for the cut frame members and assembled panels is generated. These labels are attached to the appropriate frame members and assembled panels and in accordance with the cut list and working drawings the cut frame members and panels are gathered together in an assembly for the framework. The framework is then erected and the required air handling units are inserted into the framework in accordance with the working drawings. In most cases, there will be an inlet and outlet framework and the method includes the step of gathering the coded cut inlet frame members and coded cut inlet panels in an assembly for the inlet framework.
Similarly the cut outlet frame members and outlet panels are gathered together in an assembly for the outer framework. The inlet and outlet frameworks are then erected and the framework is thus formed or jointed before insertion of the required air handling units into the framework in accordance with the working drawings.
The system and method of the invention is extremely useful in manufacturing as all the air handling systems are complicated to produce because of the large number of components involved, the number of components has been substantially reduced and the cutting and assembly method is greatly simplified.
Consequently, the number of different components is reduced to an absolute minimum and, by virtue of the cut list and interrelated coding and working drawings, the assembly method is greatly simplified so that maximum manufacturing efficiency is attained.
These and many other features of the invention will be readily apparent and accordingly the invention is not limited to the embodiments hereinbefore described which may be varied in both construction and detail.
