HEATING AND VENTILATING APPARATUS Filed Jan. 17, 1962 l l, l
FIG.4
. INVENTOR JEAN-JULIEN FORTIN ATTORNEY United States Patent O 3,126,165 HEATING AND VENTILATIYG APPARATUS Jean-Julien Fortin, 582 Blvd. Lamarche, Chicoutimi, Quebec, Canada Filed Jan. 17, 1962, Ser. No. 166,888 2 Claims. (Cl. 98-38) This invention relates to a new and improved combined heating and Ventilating apparatus, and the principal object of the invention resides in the provision of means whereby fresh filtered air may be into a building and more particularly into a room or rooms thereof individually, said fresh ltered air being then heated in a special new and improved apparatus and discharged into the atmosphere in the building or into the separate rooms thereof.
Further objects of the invention reside in the provision of a heating convectoi in the form of a cabinet or enclosure in general which may be e.g. approximately two feet high and half-a-foot wide, the same being open at the bottom and having a grill at the top for the convection of room air therethrough, and there being heating means in the cabinet together with a separate, contained insulated plenum chamber or Ventilating duct, this being connected in such a way as to be provided with fresh air, a blower directing the air through the plenum chamber, which is provided with a series of orifices therealong directing the fresh air in a generally upwardly direction inside the cabinet whereby the air is heated and is then discharged through the grill, at the top of cabinet with the convective air into the room.
Other objects of the invention include the provision of a forced fresh air system which may be utilized in warm weather without the use of the heating apparatus, and on the other hand the heating system may be utilized if necessary while the ventilation system is shut off; or both can be utilized at the same time, thus avoiding the necessity of windows that can be opened and resulting in other economies and simplicity of installation, mechanism, etc.
A still further object of the invention resides in the provision of a new and improved system of ventilation and heating as described above where air conditioning is not indicated, but which is nevertheless particularly adapted for installation in schools to the benefit of the pupils therein, and also of great advantage in factories, churches, etc. as well as in the home.
The invention further relates to arrangements and combinations of parts which Will be hereinafter described and more particularly set forth in the appended claims.
Reference is to be had to the accompanying drawings, in which FIG. 1 is a view in front elevation illustrating the invention, and
FIGS. 2 and 3 are enlarged sections on the correponding lines 2 2 and 3 3 of FIG. 1.
FIGURE 4 is an enlarged view of the orifice tab shown in FIGURE 2.
FIGURE 5, is an enlarged vertical section of the orilice tab shown in FIGURE 4.
In carrying out the present invention, there is provided a cabinet which is adapted to be mounted upon the wall adjacent to but not in contact with the floor as is illustrated in FIG. 2. This cabinet is provided with a wall l) which is uninterrupted and at its bottom it is completely open to the convection of air upwardly therethrough, the air passing out through a grillwork 16. In this cabinet there are provided pipes 18 and 2i), these pipes being finned if desired and connected to a source of heat which can be hot water or hot air or whatever the source may be, which in general will be derived through a coupling 3,120,155 Patented Feb. 4, 1964 22. The pipes may of course be replaced by electric space heating devices, gas, etc.
t is pointed out that these cabinets are particularly adapted for installation near the baseboards and may be as elongated as desired or may be placed in multiples if this is desired or convenient.
A plenum chamber or Ventilating air duct is generally indicated at 24, this being best shown in FIG. 2. This chamber does not extend the full length of the cabinet but for a major portion thereof as is indicated in FIG. 1.
The plenum chamber is arranged between the exterior wall which is indicated in FIG. 2 at 26 and it is completely shut olf from the interior of the cabinet except through a series of orifices 28 which are formed by bending back tabs as clearly shown in FIG. 2 at 29 so as to direct the air in the direction of the arrow in FIG. 2 in a general upward direction toward the grille 16.
Adjacent an end of the cabinet there is provided a small electric motor M which drives a blower, the details of which are not shown but which are well known and indicated in the general position of the reference numerals 3i) in FIG. 3. This blower is arranged adjacent an inlet port or the like 32 so as to draw the fresh air into the device and to disperse it throughout the plenum chamber. In this connection it is preferred that the chamber generally indicated at 34 for the blower should be insulated against cold and noise as is shown in FIG. 3 but in any event the air is directed through the plenum chamber and out through the orifices 28 where the air is heated and passes out through the grille and into the atmosphere of the serviced room.
Various means for mounting the cabinet may be utilized and the same is true as to the electric motor, blowers, etc. but it is pointed out that an extremely easily controlled device is presented herewith. On cold days the heating system may be thrown into operation, say for instance in the morning, to heat the room, particularly school rooms, while the ventilator remains inoperative (or merely closed), but when the room is warm enough, then the ventilator can be turned on and the heat balance maintained by the use of commercial thermostats. In warm weather, the heat may be turned off and the ventilators used to draw in the fresh air through properly arranged filters for instance, and this will provide all the fresh air that is necessary without the need for opening windows so that in fact schools (and other buildings) may be built with windows in xed condition, making a less expensive construction. When the system in the room has no need of ventilation, the blower can be stopped, saving on the electric energy; and by proper positioning of the cabinets, the ventilation and heat may be provided Wherever needed in the building. Also when individual units are used, some may be operative and some left inoperative when not needed. The electric motors used for the blowers may be made of variable speed so as to increase or decrease the effect of the ow of air and of course the filters may be varied to provide for more or less resistance to the passage of air therethrough. In addition, the orifices 2S may be Varied as to area of orifices to suit conditions encountered.
Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:
1. A heating and Ventilating device for a room comprising an elongated enclosure having a front wall, a bottom wall, a top wall and end walls, a first portion of said enclosure having an opening in the bottom Wall forming an inlet for room air, a grill at the top of the enclosure in the same area as the inlet, said grill forming an outlet for room air, said bottom opening and grill providing for the convection of room air fromtthe bottom, through, and out the top of the first portion of the enclosure, means for mounting the entire enclosure on the interior surface of an exterior wall of the room, a ventilation duct within the enclosure and located principally in the rst portion of the enclosure, said ventilation duct comprising a compartment mounted on the interi'or surface of the exterior wall of the room and extending along the rst portion of the enclosure in the area of the bottom opening and the grill, said Ventilating duct being less in height than the enclosure and considerably less in width, leaving a relatively large portion of the enclosure in the first portion of the device for the convection of the room air, the Ventilation duct being substantially closed oi from said area of convection, a pair of elongated heat sources extending longitudinally along ,the enclosure, one source being adjacent the bottom of the terior of the enclosure, a port supplying the blower with fresh air from the exterior of the room, the port beingV located in the exterior wall, fresh air owing from the outside through the port and housing into the Ventilation duct, and a horizontal line of oriiices in said ven-V tilation duct substantially midway between the two sources of heat directing the fresh air from the blower into the interior of the Ventilating duct intermediate the two sources of heat and into the stream of room air intermediate the open bottom of the first portion of the enclosure and the outlet at the top thereof, and means at each oriice directing the fresh air streams in an upward direction toward the grill.
2. A heating and Ventilating device as recited in claim l wherein the last-named means comprises tabs struck out from the front wall of the Ventilating duct Vand inf clined generally upwardly and away from the said ventilating duct.
