4 Claims. (Cl. 98-33) V l an air distrbuting unit having improved means of circulating air therethrough.
Another object is to provide a self-contained air conditioning and distributing unit having an air tempering chamber through which air is moved at substantially less velocity than the intake and outlet streams, thereby providing an in- Further objects and advantages of the invention will more fully appear from the following description taken in connection with the accompanying drawings which show, by way of example the present preferred embodiment of the invention.
The invention consists of the novel feature, arrangement and combination of parts embodied by way of example in-the structure hereinafter described as illustrating-a present preferred form of the invention, and the invention will be more particularly pointed out in the app nded claims.
In order to more clearly disclose my invention, reference is made to the accompanying drawing, in which:
Figure 1 is a vertical section showing the device installed in the ceiling of a room.
The flange fitting 4 is secured to the curved vanes 2 by means of screws 5. It will be noted that the flange 4, vanes 2, and distributing head I are securely fastened together as a unit for insertion 7 within the'ce'iline'.
In order to facilitate the mounting of the device against a flat surface, such as a ceiling 6, the flange 4 extends beyondthe joist members 1 andis secured thereto by means of screws 8.
Secured within the ceiling 6, by means of-the flange 4, is an annular housing member 9. Thus the member 9 and flange 4 form a chamber housing having a. closed top and an open bottom, and the cone-shaped distributing head I is disposed within the open end of the chamber to provide an annular space sewing as an emission nozzle within which the curved vanes or baflies 2 (Fig.
1) are positioned. The bafiles 2 are peripherally spaced and extend laterally, and are preferably curved, in general being inclined to a radial direction. Mounted at the upper edge of the housing 3, and secured to the center thereof, is a motor III having a vertical shaft I I which in turn is secured to a suction ,fan I2 for rotation therewith.-
The fan I2 is of the centrifugal type, such'as a "Sirocco fan, and is mounted centrally of the housing 9--4. I
It will be noted in Figure 1 that the upper end of the cone-shaped distributor head I is formed 'form a continuous passage providing a lower outwardly and downwardly flaring intake mouth I5 and an upper throat which is directed upwardly into communication with said chamber.
It will also be noted, in Figure 2, that the curved,
verticalvanes l4-are inclined in substantially the same direction as the direction of rotation of the blades of the fan I2; this facilitates the suction of "said fan, since the vanes I4 direct the air upwardly in a generally spiral pattern without too abrupt a change in direction from the tangential direction. I have discovered that the coaxial distheithroat in the neck I3, upwardly of the curved vanes I4 into the housing member 9. It is obvious, therefore, that when the air is sucked into the housing 9 it is deflected downward and passes over heating coils I6 which have been installed within the housing 9, These heating coils I6 can be heated electrically as at IT, or they may be replaced by a steam coil.
In the event it is desired to use the apparatus as a unit air conditioning or cooling system in the end of the chamber 9, the top and side walls of which cause the air to reverse its direction and pass downwardly around and through the tempering coil It. In its exit from the chamber, the cone I and flange 3 serve to restrict the flow;
throat forming a continuation of said fan hous- 1118, said deflector means also providing a downwardly and outwardly flaring external wall disso that the air within said chamber moves at a lower velocity and therefore may be more efficiently tempered. Furthermore, the cone deflector l and the curved vanes 2 in'the path of emitted air give the air a whirling action and direct it outwardly to effectively distribute it in the general manner set'iorth in my Patent No. 2,190,- QS'Lissued February 20, 1940,
Having described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. In an air conditioning and distributing unit, the combination of a housing having a top wall and downwardly extending peripheral side walls providing an air tempering chamber open atits lower end, conduit means centrally disposed within said housing and providing a passage of general funnel shape having a neck and a mouth, the neck of said passage being in communication with said chamber and directed toward its top and the mouth of said passage being disposed below the open end of said chambe the lower end of said conduit means having an outwardly and downwardly flaring wall providing with the lower portion of said chamber wall an emission nozzle, and a centrifugal fan mounted on an axis extending within the neck of said passage substantially coaxial therewith to draw air into the mouth thereof and pass it from said passage neck through said chamber and discharge it through said nozzle.
2. In an air conditioning and distributing unit, the combination of a chamber housing having a top wall and downwardly extending peripheral side walls terminating in a lower opening, a centrlfugel fan mounted on a substantially vertical axis and disposed centrally within said housing, a fan housing of generally circular cross-section of larger diameter than said fan and surrounding said fan to provide therewith an annular passage, a plurality of spaced deflector baffles fixed interiorly of said fan housing extending longitudinally thereof and inclined to the vertical, said fan housing being ,of smaller external diameter than said chamber housing and providing therewith an annular chamber in communication with said annular passage, and deflector means providing a downwardly and outwardly flaring inlet posed within the lower opening of said chamber housing so as to define an annular emission nozzle from said chamber.
3. In an. air conditioning and distributing unit,
the combination of a chamber housing having a top wall and downwardly extending peripheral side walls terminating in a lower opening, a centrifugal fan mounted on a substantially vertical axis and disposed centrally within said housing.
a fan housing of generally circular cross-section of larger diameter than said fan and surrounding said fan to provide a passage for restricting the tangential flow of air from said fan, a plurality of spaced deflector bafiles fixed interiorly of said fan housing extending longitudinally thereof and inclined to the vertical for directing the air axially of said fan housing, said fan housing being oi' smaller external diameter than said chamber housing and providing therewith-an annular temperature conditioning chamber in communication with said passage, temperature conditioning means within said chamber, deflector means providing a downwardly and outwardly flaring inlet throat forming a continuation of said fan housme, said deflector means also providing a downwardly and outwardly flaring external wall extending through 'the open end of said chamber housing disposed partly without and partly Within the said housing so as to define an annular emission nozzle for said temperature conditioning chamber, and a plurality of spaced laterally extending deflector bafiles positioned in said emission nozzle.
4. In an air distributing device, the combination of a centrifugal'fan, a, fan housing of genthan said fan and substantially concentrically surrounding said fan to provide an annular passage between said fan and housing, said housing having open ends providing respective inlet and outlet openings, a plurality of peripherally spa ed deflector bafiles fixed interiorly of said sleeve extending axially thereof and inclined to the axis in the direction of rotation of said fan in a generally spiral pattern for directing air axially of said passage and outwardly through said outlet passage, and a casing having an end wall disposed over said outlet and a side wall sun;
rounding said housing and providing an opening; whereby air directed axially outwardly from said fan housing is caused to flow in a reverse direction and emitted from the opening provided between said fan housing and casing.
