Description
- This application claims the benefit of U.S. Provisional Application No. 60/884,261, filed Jan. 10, 2007.
- The present application relates generally to a flange for a furnace system. More specifically, the present application relates to a removable casing flange and insulation retainer.
- The basic components of a furnace or HVAC system are: a burner, a heat exchanger, an air distribution system, and a vent pipe. In the burner, gas (natural or propane) or oil is delivered and combusted to generate heat. The heat exchanger transfers the heat from the combustion gas to the air distribution system. The air distribution system, which includes a blower and ductwork, delivers the heated air throughout the home and returns cooler air to the furnace to be heated. Finally, the vent pipe or flue exhausts byproducts of combustion (such as water vapor and carbon dioxide) outside of the home. In addition, the furnace system may also include a cooling element, such as an A-coil, that operates in conjunction with an air conditioning unit (typically located outside of the home) to provide cooled air to the home instead of heated air.
- Typically, furnace systems in residential applications are located in the basement or a small closet in the user's home, which areas have limited space for an installed furnace system. Furthermore, efficiency standards have recently changed, thereby requiring the size of the A-coil to be increased to meet these new standards. Thus, when a newer furnace system is needed to replace an older system, often, the newer furnace can not fit into the space where the old furnace was installed because the size of the furnace unit and the newer, taller A-coil that is required is greater than the available installation space. Thus, a shorter, furnace is needed to accommodate the taller A-coil in order to be able to install a new furnace system in the same space as the old furnace system.
- Most furnace systems are multi poised, meaning that they can operate in a variety of positions, including up flow, down flow, and horizontal (both left and right). In addition, furnace systems may also be a single configuration, at any height. Depending upon the position, the casing flanges within the furnace may need to be removed or modified during repositioning to facilitate the installation. Often the insulation within the casing is pulled loose and obstructs airflow. As shown in
FIG. 1 , theflange 80 protrudes from thecasing 82 and becomes a hindrance during repositioning of thefurnace 84, requiring theflange 80 to be removed entirely. Theflanges 80 are provided on the top of thefurnace system 84 by bending portions of thefurnace housing 86 andcasing 82. There are several drawbacks to this type offlange 80 including the inability to relocate theflange 80. Therefore, what is needed is a casing flange that serves as an insulation retainer and that does not have to be completely removed during repositioning of the furnace. - Intended advantages of the disclosed systems and/or methods satisfy one or more of these needs or provides other advantageous features. Other features and advantages will be made apparent from the present specification. The teachings disclosed extend to those embodiments that fall within the scope of the claims, regardless of whether they accomplish one or more of the aforementioned needs.
- A furnace system having a furnace housing with a plurality of sides to enclose the furnace system and insulation being disposed along the plurality of sides of the furnace housing is set forth herein. The system also has at least one flange disposed along an edge of the plurality of sides of the furnace housing. The at least one flange has at least one aperture for receiving at least one fastener and the at least one flange is repositionable between an externally projecting flange and an internally projecting flange. The at least one flange acts as a retainer for the insulation in the furnace housing.
- Another embodiment of this furnace system is directed to a flange having at least one aperture for receiving at least one fastener. The flange is repositionable between an externally projecting flange and an internally projecting flange, and the at least one flange acts as a retainer for the insulation in the furnace housing.
- One advantage of this arrangement is that the flange can be repositioned when desired. It can either protrude or be contained within the casing, if so desired. In both conditions, it would act as an insulation retainer.
- Another advantage of this arrangement is that the flange can be repositioned so the flange is contained within the housing and not protruding.
- Yet another advantage of this arrangement is that the flange serves as an insulation retainer, preventing the insulation from coming loose or obstructing airflow.

FIG. 4 shows a schematic arrangement of afurnace system 100, and the internal portion of thefurnace system 100. During operation, aburner 101 combusts fuel withincombustion air 102 and provides combustion products and heated air to afirst heat exchanger 103, where heat is transferred to asupply air 104.Supply air 104 is air that is to be heated, such as interior air for a building HVAC system.Combustion air 102 is then directed into asecond heat exchanger 105, where heat is further exchanged withsupply air 104.Supply air 104 is directed overfirst heat exchanger 103 andsecond heat exchanger 105 by use of ablower 107 or similar air-moving device.Combustion air 102 is then exhausted from the system by use of anexhaust blower 109 or other air-moving device. Exhaust 111 includes air, water vapor and other combustion products.Furnace system 100 provides heat to supplyair 104 by use offirst heat exchanger 103 andsecond heat exchanger 105.Supply air 104 is then provided to a space for heating. -
FIGS. 5-11 illustrate different views of one embodiment of aflange 200 used to hold theinsulation 216 that lines thefurnace housing 86 and position the ductwork of the furnace system. Theflange 200 of the current application is repositionable from the internally facing position (FIG. 5 ) where it secures and retains theinsulation 216 in place. The flange is then reconfigured to the externally facing position (FIG. 11 ) where it acts as an insulation retainer and a mounting means for the duct work of the furnace system. - The
flange 200 has one or more apertures 202 (shown inFIG. 7 ) to receivefastening devices 204, e.g. screws, which permit theflange 200 to be removed from its current position and relocated to a desired position by the simple disengagement and reengagement of thefastening devices 204. This feature of theflange 200 is beneficial for furnace systems that are designed to be multi-poised, i.e., the furnace system can be configured for operation in all four positions (up-flow, down-flow, horizontal-left and horizontal-right). Theflange 200 is repositionable to a position necessary depending on the particular configuration of themulti-poised furnace system 210. For example, theflange 200 may be positioned in a retracted or internally facing position (as shown inFIG. 5 ) and extend within thefurnace system 210. Alternatively, theflange 200 may be positioned to extend externally (as shown inFIG. 11 ) from thefurnace system 210 by simply flipping theflange 200 and reattaching it with theflange 200 extending upward. - The
flange 200 is a single unitary piece used on one side of the furnace housing 214, withadditional flanges 200 being used if needed for other sides of thefurnace housing 86. Alternatively,multiple flanges 200 can be used for a single side of thefurnace housing 86. Themultiple flanges 200 may be connectable together to form alarger flange 200 or themultiple flanges 200 may be individually mounted on the furnace side at desired locations as shown inFIG. 9 . In addition, theflange 200 can be a single unitary piece that extends along the perimeter of the sides of the furnace housing. Theflange 200 may be cast as one piece, or each of the four pieces that extend along each side of the housing may be fastened together by a weld connection or other suitable connection. Referring specifically toFIG. 8 , an exemplary embodiment of theflange 200 is arranged in a step shape, having abase section 220 with afirst flange protrusion 222 extending upward from one side of thebase section 220 and asecond flange protrusion 224 extending downward from the opposite side of thebase section 220. However, theflange 200 may be configured in any suitable shape. - Finally, regardless of whether the
flange 200 is in a retracted position or an extended position as shown inFIGS. 10 and 11 , respectively, theflange 200 also operates as an insulation retainer. Theflange 200 is used to capture orsecure insulation 216 to prevent theinsulation 216 from coming loose and causing problems such as obstructing the airflow through thefurnace system 210. Further, theflange 200 is also used for securing the supply/return duct and/or coil cabinet to the furnace. Theflange 200 is repositionable to accommodate supply duct or return duct variation from installation to installation. - While the systems and/or methods of the application have been described with reference to several embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the application. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the application without departing from the essential scope thereof.
