United States Patent O 3,504,661 ATMOSPHERIC VENT SYSTEM Richard L. Morris and Harlan H. Blievernicht, Indianapolis, Ind., assignors to Carrier Corporation, Syracuse, N.Y., a corporation of Delaware Filed Feb. 28, 1968, Ser. No. 708,927 Int. Cl. F24h 3/00; F23j 11/00 US. Cl. 126-116 4 Claims ABSTRACT OF THE DISCLOSURE A combustion air inlet and flue gas exhaust arrangement to provide proper combustion for a gas furnace adapted for exterior use and therefore ubjected to varying wind velocities and directions.
BACKGROUND OF THE INVENTION SUMMARY OF THE INVENTION This invention relates to a furnace having an atmospheric vent system comprised of a gas control compartment and flue gas collection compartment, the control compartment, which communicates with the furnace burners, being provided with grilled inlets on each side thereof and a grilled inlet along the top of the front portion thereof for entrance of combustion air, the flue gas collection compartment, which communicates with the flue gas openings in the furnace heat exchanger, being pro vided with grilled openings on the top and the lower front section thereof for discharge of flue gas therefrom. Vertical wind deflecting vanes, perpendicular to the plane of the front grilles in both compartments, in conjunction with external shields parallel to the front grilles and internal shields parallel to the side grilles minimize the effect of varying wind direction and velocity to provide proper combustion and elimination of flue gas.
BRIEF DESCRIPTION OF THE DRAWINGS FIGURE 1 is a perspective view of a furnace incorporating the present invention;
FIGURE 2 is a front view of the furnace of FIGURE 1 with the front panel removed; and
FIGURE 3 is a partial side view of the furnace in section.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawing, there is illustrated a gas furnace suitable for installation on the roof of the building to be heated thereby. The furnace is comprised of a casing 11 having a heat exchanger 13, burners 15 and a blower (not shown) disposed therein.
An atmospheric vent cabinet 17 is provided for attachment to the front of the casing in a suitable manner such as welding. The cabinet is divided into two compartments 19 and 21 by partition 23. The bottom or control compartment 19 is provided with front grille 25 and side grilles 27 for admission of combustion air for burners 15. The
3,504,661 Patented Apr. 7, 1970 ice top or flue gas collection compartment 21 is provided with top grilles 29 and front grille 31 for passage of exhaust gases discharged from openings 33 of heat exchanger 13.
The furnace of the present invention, by the inclusion as an aerodynamic vent terminal which provides a balanced pressure in both compartments of the cabinet even when the furnace is subjected to winds of 40 miles an hour from any direction.
While we have described a preferred embodimnt of our invention, it will be understood the invention is not limited thereto but may be otherwise embodied within the scope of the following claims.
We claim:
1. A furnace having burners associated therewith, the furnace being adapted for exterior installation and operation when subjected to varying wind directions and velocities including:
means defining a first compartment communicating with the furnace burners,
a first grille in the front of said compartment opposite the burners at a higher elevation therefrom,
second and third grilles, opposite each other on the sides of said compartment at an elevation above the furnace burners, said first, second and third grilles providing passages for entrance of air into said first compartment,
shield means associated with said first, second and third grilles to prevent direct passage of air into said compartment,
vane means associated with said first grille to neutralize stray wind vectors entering said first grille,
means defining a second compartment communicating with the furnace heat exchanger openings for receiving products of combustion therefrom,
front and top grilles means in said second compartment for discharge of the products of combustion therefrom,
shield means associated with said front grille to prevent direct entrance of wind into said second compartment, and
vane means in said second compartment associated with said front grille to neutralize stray wind vectors entering said front grille.
2. A furnace according to claim 1 including:
a cabinet having top, bottom and side panels affixed to said furnace, the front of said furnace serving as a back for said cabinet,
a removable front panel for mating engagement with the top, bottom and side panels of said cabinet to form a closure, and
a partition disposed in said cabinet parallel to top and bottom panels thereof to form said first and second compartments.
3. A furnace according to claim 2 wherein said vane means associated with said first grille comprise a plurality of downwardly extending first vanes aflixed to said partition, parallel to said side panels, and
said second vane mean associated with said front grille comprises a plurality of upstanding vanes afiixed to 4 the top of said partition parallel to the side panels of References Cited said cablnet, said second vanes being centered on UNITED STATES PATENTS the heat exchanger openings. 4. A furnace according to claim 3 wherein said shield 2,919,590 1/ 1950 Hornmeans associated with said first grille and said front grille 5 2,632,435 3/ 1953 Lundstrum. comprises: 3,429,307 2/ 1969 Eubanks.
plates parallel to and spaced from said grilles on the exterior of said cabinet, and CHARLES MYHRE, Primary Examiner said shield means associated with said second and third grilles comprises plates parallel to and spaced from 10 said side panels on the interior of aid cabinet. 126-85
