This invention relates to air conditioning apparatus and has particular reference to apparatus which will provide the ali in one or more rooms with the proper degree of humidity which is most healthful to the occupants or which may be required for carrying on certain manufacturing or other processes in which a definite amount of moisture is necessary in the surrounding air.
Theprincipal object of this invention is to provide air conditioning apparatus which treats the air already in the room so as to render it fresh and pure without requiring the introduction of outside air, and which also continuously purifies and cools the air treated thereby in large volume so that all of the air in the room or rooms is conditioned by the apparatus in a relatively short time.
A further object of this invention is to provide apparatus of the type described which may be inserted in the space between the studs in the wall of a room so as to lie flush with the surface thereof and present 4 an attractive appearance in the formof a decorative panel having two louvred apertures, one for the intake of the air from the room,.and the other for the, return of the conditioned air into the room. After inserting the apparatus into the wall in this way, no other operations in the room, such as .replastering, repapering or the like are necessary.
A further object of the invention is to provide an air conditioning apparatus which is simple to operate and install, requires no attention beyond occasional inspection, and which has no moving parts, so that it is not likely to get out of order during long periods the building with water. The circular water spray acts as a piston moving continuously down through the interior of each tube and serves to draw air through the opening in the upper header and force it through the opening in the lower header, while humidifymg, washing and cooling the air thus circulated. Within each, of these circular tubes is preferably mounted a spiral bafile which imparts a swirling motion to the descending spray in order to precipitate surplus particles of water carried by the descending air this action being augmented by a series 0 bafiies in the lower header by means of which the direction of flow of the air is suddenly changed several times, whereby further surplus water entrained thereinis precipitated.
This casing is removably secured by suitable means between the studs of the wall in which it is mounted. It is covered by, but is made accessible through a movable panel having louvres at its upper and lower ends which register with the corresponding apertures in the headerspf the casing. This panel may be suitably hinged to the wall as adoor, or may be held in place by clips or the like so as to be entirelyremovable'therefrom, and isformed of decorative wood, metal or the like, preferably fitted with a mirror, picture, tapestry or combinations of these and the like, between the upper and lower louvres.
lated by the apparatus described, the number of tube and nozzle combinationsv may be increased or an electric fan may be'mounted opposite the upper or lower louvres, this fan For increasing the amount of air circu- I being preferably mounted upon the inner surface of the panel, together with the electric wiring required therefor.
The novel nozzle for creating the circular spray within each of the tubes includes three chambers connected in series by small tangenital holes, whereby the water, under normal pressure, flows at increased velocity from the first chamber into the second chamber with a swirling action and from the second .chamber into the third chamber with further increased velocity and swirling action, from which it flows through a small orifice in the shape of a conical spray of circular cross-section, which completely closes the tube against the admission of any air except that which is drawn through the spray because of the suction created thereby.

In these drawings numeral. 20 designates the wall of the room in which the air conditioning ap aratus of this invention is to be mounted, t e studs in the wall being designated 21. In the vertical section illustrated in Fig. 1, the upper and lower box-like housings or headers 22 and 23, respectively, are preferably formed of sheet metal such as sheet copper, and are made identical for manufacturing purposes, each being provided with a slde openin the opening in upper header 22 being desl nated 24, and the opening in the lower hea er 23 being desig nated 25. These upper and lower headers are spaced and secured together by suitable tie rods 26. Circular apertures are formed in the adjacent surfaces of the headers 22 and 23, for the insertion of vertical tubes 27 which are preferably straight tubes of circular cross-section, the lower edges of which are turned inwardly and upwardly to form an inclined gutter 28 having a notch 29 at its lowermost point, which discharges surplus water into a trough 30 secured to the rear inner surface of lower header 23 communicating with a down-spout 31, which terminates near the bottom or sump of header 23. The surplus water collecting in the bottom or sump of lower header 23 flows through a screen dome 32 into a discharge pipe 33 which is connected to the sewer or other suitable drain.
Within each of tubes 27 is mounted a spiral baffle 34, which may be made of a strip of sheet metal such as copper twisted through an angle of 180 or more degrees. This bafile 34 is spot-soldered or otherwise fastened within tube 27 and is provided at its lowermost edge with an inclined V- shaped gutter 35, which discharges into gutter 28 formed on the lower edge of each of the tubes 27 An alternative form of this spiral .baflie 34 is designated 34' in Fig. 7,
and is preferably made of a strip of metal fabric or the like secured at its lower edge to brackets 36 mounted adjacent the lower end of tube 27, and held taut at its up er end by means of springs 37 adjustably mounted in brackets 38 mounted near the upper end of tube 27. In order to keep this strip of metal mesh formin baflle 34' in proper shape, a series of sti ening battens 39 are secured thereto at spaced intervals. This alternative type of spiral baflle 34' has a certain advantage over the sheet metal type of bafile 34 shown in Fig. 1 in that the air may flow through the openin s in the mesh in intimate contact with the water adhering to the mesh whereb an additional air screening and humidif yi takes lace.
\Vit lin lower header 23 are mounted a series of haliles 40, alternate ones of which extend respectively from the front and rear ng action inner surfaces of header 23 so as to cause baille arrangement is shown in Figs. 5 and 6, in which baillos 40' cross each other, one
extending from the rear wall of header 23, and the other extending from the front. wall thereof. With this arrangement the air is reversed in two directions, that is, from front to rear and from side to side, as seen 'in Fig. 5, whereby a most effective precipitation of excess water from the air is obtained. In both of these arrangements, the streams of moisture-laden air emerging from the lower ends of tubes 27 is unconstricted so that its velocity is'not changed substantially, and is freed of excess moisture by the sudden changes in direction imparted thereto by the baflies 40 and 40', so that the washed and humidified air emerges from opening without precipitating water outside of the apparatus. A curved deflector 41 is mounted within lower header 23 for the purpose of deflecting the air at right angles through the opening 25, and also serves to house the strainer 32-and the sump of header 23. Deflector 41 is perforated at its forward edge to allow the excess Water to flow intothe sump for discharge through drain 33.
Inserted water-tightly through the bot- 2 tom of header 23 is the water supply pipe 42, which preferably passes upwardly between tubes 27 through a suitable filter 43, which removes the particles of dirt or grit which may be contained in the water. A
which clamp it securely in position, but which may be loosened by manipulating wing nuts 47, so that the entire manifold 45 may be turned at right angles for inspection or cleaning of nozzles 48 through aperture 24, This may be done by disconnecting nipple 49 after the water is shut off by means of hand regulating valve 50, or a piece of flexible tubing may be inserted in place of the nipple 49, so that themanifold 45 may be turned in brackets 46 'after the wing nuts 47 have been loosened without disconnecting the water pipe 42 therefrom.
A modified form of baflle is illustrated in Figs. 12 and 13, which are front and front perspective views, respectively. The side in turn deflect the air against the side walls of the bcttom'header 23 from which it is deflected inwardly against the curved sides louvre opening 67 and is of such shape as to deflect the air sidewise therethrough so that a wide air distribution without draft is obtained.
A nozzle 48 is mounted directly over the upper open end of each of tubes 27 and introduces'into these tubes a fine conical water spray at high velocity, which completely closes tubes 27 and acts as a piston moving down each tube 27 so as to create a suction which induces a continuous flow of air in large volume, the air passing through the fine spray and being forced thereby downwardly through tubes 27.- The construction of nozzle 48 is shown in detail in Figs. 9, 10 and 11, and includes a nipple 51 threaded at the smaller end for connection with manifold 45, and also threaded at its larger end for the reception of cup 52 having a large opening 53, through which the, spray emerges. Nipple 51 is drilled axially at 54 so as to form a chamber for the recep-' tion of the water from'manifold 45. The lower edge of nipple 51 is undercut so as -to.form with the inner walls of cup 52 an annular chamber 55; Two or more small holes 56, drilled tangentially, connect chamber 54 with annular chamber 55 as shown particularly in the cross-section of Fig. 10. The lower surface of nipple 51 is drilled axially to provide another or third chamber 57, which communicates with annular chamber 55 by means of small, tangentiallydrilled holes 58 shown particularly in Fig.
11. Between gaskets 59 within cup 52 is mounted a circular disc 60, having a small. central opening 61 communicating with chamber 57. A gasket 62 is interposed between the upper edge of cup 52 and a nut 63, which may be tightened down on the gasket 62 so as to render the device watertight at this point also.
It will be seen that water entering first chamber 54 at ordinary water main pressure is distributed atincreased velocity through tangential holes 56 into second chamber 55 in which it swirls at high velocity in the direction of the arrow in Fig. 11 because of the tangential arrangement of the holes 56. The swirling water in second chamber 55 then passes in the same direction with increased velocity through smaller holes 58 to swirl in the direction of the arrow in Fig. 11 within third chamber 57,
from which it emerges through pin hole "61 in the form of a swirling conical spray which completely closes the circular tube 27 arranged directly below the nozzle 48 as shown in Figs. 1 and 2. h
The opening in the wall 20, into which the apparatus has been inserted, is preferably rimmed by a frame 64 of decorative wood, metal or other suitable material, this frame being attached to the surface'of the wall by suitable means without in any way marring or disturbing the paper, plaster,
and 23, respectively. Between louvre openparatus including the ings 66 and 67 is mounted a mirror, tapestry, picture, decorative panel or combinations of theseand the like, whereby the apparatus presents a pleasing appearance without in any way detracting from its eflicacy as an air conditioning apparatus. Of course, instead of being hinged to the frame 64, the panel 65 maybe removably clamped or screwed thereto. Also, the frame or casing of the apparatus may. be mounted in a separate housing, instead of in the housing formed by a recess in a wall as described, so as to be portable, the front cover of the apanel or door being secured directly to the rame or casing or to the portable housing.
In order to place the air conditioning apparatus of this invention in operation, valve 50 is opened so that the water spray emerges from nozzles 48. The velocity of the water spray may be regulated by valve 50 in accordance with the pressure indicated by gauge 44, and as the volume of air circulated by the apparatus depends upon the velocity of the spray, the gauge 44 may be calibrated to indicate the cubic feet of air changed per minute. The descendin spray of water creates a suction throug upper louvre 66, so that air is drawn from the room at a point preferably near the ceiling and is forced through tubes 27 b the descending spray of water. The spira baflles 34 or 34' within tubes 27 impart a spiral motion to the air and water mixture and the excess water flows down the inner surfaces of tubes 27 and the surfaces of bafiles 34 or 34' to be carried off by gutters 28, drain trough 30 and down-spout 23 into drain pipe 33. The surplus water is removed from the air by the baflles 40, which rapidly reverse the direction of flow of the air. During this processs the air has been humidified and washed of all dust and other impurities, and has been cooled down to approximately the temperature of the water used, so that it emerges from lower louvre opening 67 in the form of fresh, ure air.
'In the event that a greater air 0 ange is required, the'velocity of the water may be increased by means of a booster pump or the like, or an electric fan 68 may be mounted adjacent the upper louvre opening 66 as shown in Fig. 8. The fan 68 is preferably mounted on a bracket 69 secured to the rear of the door 65 and extending across upper louvre opening 66, and the electric wires may be inserted in a groove in the door so as to be invisible. It is also preferred that the interior of upper header 22 be'shaped or provided with a curved hood 70 in order to prevent the formation of air pockets and eddies. A greater air change may also be obtained simply by increasing the number of nozzle and tube units without the need of additional apparatus. Another wayof increasing the velocity of the air is to form tubes 27 m the shape of Venturi tubes, not
shown.
It will be seen that the air conditioning apparatus of this invention offers many advantages over those which have been heretofore used, in that the volume of air treated thereby is greatly increased for the same water consumption without the necessity of employing auxiliary a paratus for procuring this advantage. The device is readily installed in the rooms of buildings already constructed or being constructed, and furnishes roperly 7 humidified and purified air whicis most healthful for the occupants of the room or rooms. Furthermore, the device may be installed in larger sizes in factories or the like for properly conditioning the air where the humidity in' the air is an important factor in a manufacturing process or the like.
