United States Patent 3,225,677 JUNCTION CHAIVEER FOR EQUALIZING PRES- SURE OF CONDITIONED-AIR SUPPLY INCOR- PORATING RETURNED-AIR DUCT Richard M. Steele, P.0. Box 1121, Stockton, Calif. Filed Oct. 10, 1963, Ser. No. 315,273 2 Claims. (Cl. 98-33) This invention relates to the equalization of the pressure of a volume of conditioned-air introduced into and contained Within a chamber, the chamber holding the supply of conditioned-air which may be tapped by two, or more, outlet ducts as may be desired or required.
Various air-conditioning units of reversible type, known in the vernacular as heat-pumps, that is, for supplying air heated or refrigerated as desired, are presently in use or under development. One object of this invention, as titled above, is to provide means by which, when used in combination with such an air-conditioning unit, or heat-pump, the conditioned-air produced thereby may be equally pressurized within a chamber, for the purpose, causing an evenly pressurized supply of the conditionedair to outlet ducts. In addition to this novel and valuable object, there is, further, the object to provide a compact arrangement by which the outlet ducts may be readily and conveniently spaced in attachment to the junction chamber so that conditioned-air, from the chamber, tapped by ducts, may be directed in multiple directions to the desired, or required, areas for use. The chamber, itself, is installed, generally, within or through, adjacent or contiguous to a wall or ceiling segment, floor, or the like. Also, another important and novel object of the invention of this particular chamber is to provide a suitable and compact means by which the return of air from areas of use, such returned-air being generally exhausted of its air-conditioned characteristics, is made directly to the airconditioning unit, or heat pump, through a returning-air duct sealed within and penetrating through the chamber.
The device is manufactured, preferably, of sheet metal, or of other relatively stiff fibre, plastic and rubber, or of material found or deemed suitable, and the device is intended for installation primarily by the construction and building profession or trade.
The heretofore stated novel and valuable objects of the invention may be ascertained in greater detail by reference to the accompanying drawing which illustrates a typical embodiment.
FIGURE 1 is a plan view depicting the top of the junction chamber.
FIGURE 2 is a View of the front elevation of the chamber, drawn to the same line as FIGURE 1.
FIGURE 3 is a perspective view with cut-away of approximately three-quarters of the front elevation, one of the outlet ducts, and the entire left side of the chamber, thus, showing the interior.
FIGURE 4 is a vertical cross-sectional view diagrammatically indicating the relation of the junction chamber conjoined to an air-conditioning unit.
Referring to the drawing, the small numbers designate the same parts appearing in all the views.
In FIGURE 1, it is readily discernible that a chamber 1 is provided for holding, as in a reservoir, the supply of a volume of conditioned-air 1a. Within this total volume 1a of the chamber 1, the conditioned-air 1a is found to be under a definite and given, even pressure by reason of its physical containment within the chamber 1. The chamber 1 may have joined to it in tapping attachment two, or more, outlet ducts 2, so attached to the front side 9, not overlooking the possibility that such outlet ducts 2, generally, may be so attached, also, to the top 4 as Well as to the right and left sides and the bottom of 3,225,677 Patented Dec. 28, 1965 "ice the chamber 1, as may be required. It follows that the conditioned-air 2a, supplied under pressure by the airconditioning unit, is conducted from the pressurized reservoir volume 1a via the outlet ducts 2 in multiple directions to areas of use, elbows being used in the continuation of the outlet ducts 2, as is well understood.
There is shown the returned-air duct 3 which is sealed within and which penetrates through the chamber 1. The returned-air duct 3 conducts the returned-air, returning from areas of use, back through the chamber 1, that is, the volume 3a being entirely sealed off, airtight, from the conditioned-air volume 1a. The returned-air duct 3 is joined by method of welding, or the like, at the points of penetration of the chamber 1, generally at the front side 9 and at the back side 5, so that the returned-air duct 3, within and without, and the chamber 1 are made airtight respectively.
Also, in FIGURE 1, diagrammatically, there is shown the back side 5 of the chamber 1 placed in position in airtight connection with the face section 6 of an airconditioning unit, or heat pump.
In FIGURE 2, it will be observed that the back side 5 of the chamber 1 is arranged as may be required to meet contiguously and to join to the face 6 of an airconditioning unit in two distinct, congruous, and airtight sections, or apertures, namely: upper 7 and lower 8, as shown by the dotted lines. The upper aperture 7 of the back side 5 is joined to the upper section of the face 6 of the air-conditioning unit from which section is supplied and obtained the conditioned-air 1a introduced into the chamber 1, filling the volume 1a, as a reservoir, under a definite, given pressure. The lower aperture 8 of the back side 5 is joined to that section of the face 6 of the air-conditioning unit which receives back to itself the returned-air 3a for processing or treatment. It will be observed that the generally round, tubular returned-air duct 3 may modify gradually to become rectangular, as it progresses through the chamber 1 from the front side 9 to the back side 5, thereby presenting a rectangular shape at the lower aperture 8 to fit congruously and airtight to that section of the face 6 of the air-conditioning unit which receives the returned-air 3a, and which may be substantially shaped to require such a rectangular shape at the termination of the returned-air duct 3 to so fit. Other modification may be made of the returnedair duct 3, without alteration of the operating principle of this device and of the member, to terminate in square or oval shape, or other, and of different size, as may be required to fit as hereinbefore disclosed, depending upon the particular design of the conjoined air-conditioning unit, as is Well understood. Also, similarly, depending upon the particular design of an air-conditioning unit, modification of shape and size may be made as may be required of the upper aperture 7 of the chamber 1 pertaining to its congruous and airtight juncture with that section of the face 6 of the conjoined air-conditioning unit from which section the conditioned-air 1a is obtained and introduced into the conditioned-air reservoir volume In.
In FIGURE 3, illustration is made of the conditionedair volume 1a within the airtight junction chamber 1, with the short, thick arrows indicating the general interior volume provided for the conditioned-air In, as in a reservoir, including that volume totally surrounding, circumferentially, the penetrating returned-air duct 3 as it progresses through the chamber 1. The light dotted arrows indicate the returned-air volume 3a within the returned-air duct 3, which is airtight also, the returned-air 3a, thus, being conducted back to the air-conditioning unit.
Without alteration of the novel operating principle of this device, or of any members thereof, it is here specified that all of the surfaces of the junction chamber 1, in particular, all of the interior surfaces, as well as the external surface of the within sealed returned-air duct 3, may be treated with insulation material, as indicated by the designated segment of insulation material 10, for the purpose of insuring greater stability in the temperature of the conditioned-air 1a while it is contained in the chamber 1, and to reduce or mufile vibratory sound which, otherwise, may be transmitted from the conjoined air-conditioning unit.
The preceding explanations of FIGURE 2 and FIG- URE 3 will generally apply in describing the cross-sectional view, FIGURE 4.
In the foregoing there is disclosed and made manifest a distinctly novel and worthy device comprising a junction chamber which evenly pressurizes a volume of conditioned-air introduced therein for convenient and compact supply through outlet ducts to areas for use, while returned-air is conducted through the junction by means of an incorporated returned-air duct penetrating, sealed within, and made airtight within the junction chamber.
As the disclosures herein might well be altered otherwise without defeating their novel and practicable applications, I do not wish to be confined to the embodiment illustrated herein further than I am limited by the scope of the appended claims,
I claim:
