3 Claims.
This invention relates to ventilating and air conditioning systems and relates more particularly to the distribution of air from such systems.
This invention provides an air distributingduct which may bein the form of an oversized mop board or base board which will extend around the sides of a room, and distribute air into the room from a plurality of points. The duct may be used at the floor of the room for distributing heated air; or used as a ceiling molding'ior distributing chilled air. Such duct are particularly suitable for older type buildings where it is dif ficult to conceal duct work.
A feature of this invention resides in providing in-such a duct, an inner chamber into which the conditioned air is supplied under pressure, the inner chamber having a Wall containing a large plurality of relatively small perforations which discharge the air at a relatively high velocity into an outer chamber. The air expands in this outer chamber and is discharged through relatively large apertures and at a relatively low velocity into the room.
Objects of the invention are to distribute air uniformly and at low velocity into a room, and to accomplish this with a decorative duct which can readily be applied around the sides of a room to be supplied with conditioned air.
The invention will now be described with reference to the drawing, of which:
Fig. 1 is a side elevation, partially in section of 1 a duct embodying this invention and formed as a base board around the sides of a room, and
Fig. 2 is a diagrammatic plan View of a room utilizing the duct of Fig. 1, and illustrates the air supply to and the distribution from, the duct.
The duct has the back wall 5 which is adapted to be placed against the inner surface of a vertical Wall of the room. The wall 6 having the perforations l, is arranged parallel to the wall 5 and spaced therefrom and has the horizontal upper portion 8 which contacts and i attached to the wall 5.
The walls 5 and 6 form an inner chamber 9 which is connected by the supply duct ID with a conventional ventilating, heating or air conditioning system which is not illustrated and which is of the type which supplies air under substantial static pressure through the duct I0 into the passage 9.
The decorative outer wall I I ha the curved up per portion I 2 which is attached to the upper end of the wall 5, the lower portion of the wall H being spaced from and extending parallel to the iii of the wall l2 interconnects the walls II and ti and forms therebetween the outer expansion chamber l3.
The wall I I has the closely spaced outlets (4 adjacent and extending parallel to the floor of the room, and has the upper outlets 15 adjacent the sides of the room and discharging air parallel thereto. I
The above described duct preferably extends around the four sides of the room, being continuous except for door passages.
As illustrated by Fig. 2, there may be two oppositely disposed supply ducts [0. One or more than two ducts It! may be provided.
In operation, the duct l0 supplies air under pressure into the inner chamber 9. Due to the small outlet l, a uniform static pressure is built up in all portions of the inner chamber 9. The air issues from the apertures 1 at a relatively high velocity which may, for example, be 3,000 feet per minute.
The discharge outlets l 4 and I 5 have total areas substantially larger than the total areas of the apertures 1 whereby the air is discharged into the room at a relatively low velocity which may, for
example, be 500 feet per minute.
The use of the double plenum chamber in the duct thus provides uniform distribution all around the room, yet with low velocity discharge into the room.
The wall I I may be of wood or of metal treated to imitate wood so as to blend artistically with the room interior.
perforated wall 6. The horizontal lower portion 55 The above-described features could, of course,
i be included in a duct adjacent the ceiling of the room as probably would be preferred for distributing chilled air. Ducts embodying the invention thus could be used adjacent the floor of the room for distributing heated air, and adjacent the ceiling of the room for distributing chilled air.
While one embodiment of the invention has been described for the purpose of illustration, it should be understood that the invention is not limited to the exact apparatus illustratedas modifications thereof may be suggested by those killed in the art without departure from the essence of the invention.
What is claimed is:
1. An air distributing, duct for placement against, and for extension along, the vertical side of a room, comprising a relatively long, a relatively high and a relatively narrow casing having a base for placement on the floor of said room, an inner wall extending substantially vertically from said base, and a partition in said casing having a substantially vertical portion spaced from said wall and having an upper portion conmeeting with said wall below the upper end thereof, said partition dividing said casing into inner and outer chambers, the upper portion of said outer chamber extending over said inner chamber, said partition having aplurality of relatively small apertures therein, said casing having an inlet in said base thereof for connecting said inner chamber, to an air supply duct the outer wall 01' said casing having: a plurality of outlets therein above said upper portion of said partition, the area of said outlets being substantially greater than the area of said apertures whereby the air from said outer chamber is discharged upwardly above said inner chamber into the room at a velocity substantially less than the air is discharged through said apertures from said inner chamber into said outer chamberl 2. An air distributing duct for placement against, and for extension along, the:v side of a room, comprising a relatively long,. a; relatively high and a relatively narrow casing; having; a substantially vertical inner wall, apartition, in said casing. having a substantially vertical: portion spaced from said Wall andhav-ing; an upper portion connecting: with said wall, said partition dividing said easing into inner and outer chambers, said partition having a plurality of relatively small apertures: therein, said casing having an inlet in the basethereof. iior connecting said inner chamber to an air supply duct, means forming an air outlet in the; outer wall of said casing for directing air from said: outer chamber along substantially vertical lines, and means forming an. air outlet in said outer wall of said. casing for directing air from said outer chamber along, substantially horizontal lines, the area of said outlets being substantially greater than the area of said apertures whereby the air from said outer chamber is discharged into the room at a velocity substantially less than the air is discharged through said apertures from said inner chamber into said outer chamber.
3. An air distributing duct for placement against, and. for extension along, the side of a room, comprising, a relatively long, a. relatively high and a relatively narrow casing having a substantially vertical inner wall, a partition in said casing having a substantially vertical portion spaced: from said wall and having an upper portion connecting with said wall; said partition dividing said casing into inner and outer chambers,. said partition having a plurality of relatively small apertures therein, said casing having an inlet in the base thereof for connecting said inner chamber to an air supply duct, means forming an air outlet in the upper portion. of the outer wall of said casing. for directing. air from said outer chamber along substantially-vertical lines, and means forming an. air outlet in the lower portion of said outer wall of said casing for directing, air from said outer chamber along substantially horizontal lines, the area of said outlets; being substantially greaterthan the area of said apertures whereby the air from said outer chamber is discharged into the room ata velocity substantially less than the air is discharged through said apertures from said. inner chamber into said outer chamber.
