Sargent, Portland, Maine Application April 25, 1934, Serial No. 722,264 6 Claims. (Cl. 257-8) This invention relates to air-conditioning ap lowing speci?cation, when taken in connection paratus. ' In its fundamental characteristics ‘it somewhat resembles the apparatus designed for a similar 5 purpose, on which United States Patent No. parts in all the different views, and in which, Fig. 1 is a plan view of the apparatus, partly 5. 1,916,907 was issued to me on July 4th, 1933. In my present conception I have sought to make and have succeeded in making several im ditioner box; movements which differentiate it from my for mer invention. For instance, in the matter of. the conditioner box; humidi?cation my present apparatus is con structed to provide a greater amount of moisture with the expenditure of less power for heat gen 1 with the accompanying drawings in which like reference characters are employed to identify like eration than obtained in my previous air-condi tioner, this advantage being procured by segre gating a small body of water from the main sup ply tank and applying the heat‘ to this lesser quantity of water, with the result that the latter can be brought to the vaporizing point much 20 more expeditiously and with a largely decreased in section, the cover being removed from the con 'Fig. 2 is a sectional elevation, longitudinally of Fig. 3 shows one method of vaporizing the wa ter, the view being partly in section taken on line 3-3, Fig. 1; ‘ Fig. 4 is a fragmentary view of the air-condi tioner showing an alternative form of structure for vaporizing the water, together with ya con stant water level maintaining mechanism; Fig. 5 shows a method of heating the tank wa ter by a coil connected with a radiator; Fig. 6 illustrates the conditioner when employ ing a jet humidi?er operated either by a pump cost for electric current for heating purposes. or by service main pressure; I have provided, means for manually re-?lling the supply tank with water, but in instances where water from a service main is available, Fig. 7 shows, in an enlarged view, the connec tion between the conditioner and the window; Figs. 8 and 9 illustrate, respectively, a front 25 automatic means for maintaining a constant level of the water is a preferred arrangement. I have also made in my present apparatus ex tensive changes in the air-cooling facilities, as I have found that'to appreciably lower the tem 30 perature of the air in an ordinary size room a cooling device more or less on the order of the conventional type of refrigerating machine is and a sectional elevation of the shutter; Fig. 10 showsan alternative ‘form of structure to retain the device in the window space. Referring to the drawings, W represents a win dow sash and S the window space-adjacent which latter the outer end of my apparatus is posi tioned. . In my fully equipped air-conditioner I employ required. To this endjI provide a space in my a double compartment box or container, the com _ present apparatus in which a cooling coil, served partment I housing a conventional type refriger ating plant (not shown) and the compartment in the box 2 containing the various elements used 35 by a small refrigerating machine, is permanent ly installed, its use being dispensed with, how-‘ ever, during the colder months of the year. The air-?ltering element of my present de vice is made of a mineral product and is sub stantially similar to the corresponding part of my former air-conditioner. I have adopted a rotary, perforate plate shut ter by which I amrenabled to restrict the pas sage-way for air into the conditionerv variably. - The out-door end of my improvedapparatus is so constructed that in its contact with the win dow no obstruction is offered to fully opening or fully closing the latter; and on each side of the . conditioner box, ?lling the window ‘spaces, are 50 ?llers, these like the box being provided with weather strips which contact the window and window frame parts to make a weather-proof ’ joint on all sides of the, window opening. Other objects and advantages will be apparent by reference‘ to the description found in the fol 5 in treating the air, including heating, cooling and humidifying it. The pipes P. P. extend from the refrigerating plant in compartment I to the .cooling coil C. C. in the box 2. The box in which 4 is compartment I is discarded when the refrig erating plant is not included in the air-condi tioning equipment. _At the extreme end of box 2, adjacent the window, I provide a slide-Way 2a in which, if desired, a ?y screen 3 may be mounted. The use of a screen is optional and not absolutely essential, as in practice the ?ltering element may serve both as a screen and as an air cleaner. However, the screen is e?lcacious in excluding ?ies, mos quitoes and certain physical objects suspended in the air. » Furthermore the screen acts to prevent the larger. objects entering the screen-box and clog ging the ?ltering element which, as a matter of 55 2 2,082,042 fact, should be left free‘ to handle the minute particles in the air. _ ing to the percolator vapor in humidifying the air. - . , Inwardly of the ?y-screen slide-way is a shut - A modi?cation of the foregoing method of ter 4, made preferably in the rotary, perforate segregating a small body of the water for inten sive heating is illustrated in Fig. 4whereln is shown a small open top tank 29 having interior communication with the main tank |4 through the automatically actuated valve 30 which de plate type, equipped with a handle 5 movable in the slot at in the cover 2b. By actuation of the handle, any degree of opening, from fully opened to fully closed positions of the perforate plate 4 rotating over the perforate back plate 4a may be had. The shutter rotates from a central pivot pin "4b. . Still further'inward‘ly of the box 2 is an air ?ltering element 6, constructed of mineral wool or spun glass. The ?ltering element is slidably 15 disposed in the slide-way ‘I and may be removed therefrom through a slot 8 in the cover by grasp ing. the lugs 9. A motor I0, equipped with a fan-wheel || drafts air from the outside into the interior of ' 20 the box 2, forcing the air through the cooling coil C. C. and heater [2, thence through an open ing l3 in the water tank l4 and the grill I5 into pends on the conventional ball float 3| to regu late the admission of water into the smaller tank to maintain a constant level of water therein. An electric heater 32‘ is calculated to raise the water in tank 29 very rapidly and vapor rising therefrom passes of! through opening l3 similar ly to the previously described method of vapor 15 izing the water. In the last method described, the tank l4 may be manually ?lled by removing the cap I41) and . using a ladle or bucket; or, if. a water service main is accessible, the pipe line may be connected 20 to the tank and by the use of valve I41) it may be ?lled whenever required.

' ‘ 25 very direct and straightforward course through conditioner a very ‘simple method of heating the 25 the box 2 thereby increasing the distance to which it may be projected into the room. One of the features characterizing my present invention pertains to the method of humidifying 30 the ?ltered alrbefore being blasted into the in tank- water is to mount a coil Z, as seen in Fig. terior space. ' In Figs. 1, 2 and 3, I illustrate what I designate as my percolating system of humidi?cation. It embodies'the use of a small, shallow tank It having interior communication with the large 5, within the tank and make connections to the radiator section nearest thereto. ' In certain instances it might be found neces sary, in order to supply a su?lcient output of 30 moisture, to employ a small atomizer or jet type humidifying element to augment the vapor procured through the heating method. In Fig. 6, the jet humidifier is shown at 34 and at M is a connection which extends to the main ,water service pipe; W. P. represents a water Within tank I6 is an electric heating unit I8, pump haying on its suction end direct connec-. surrounding and spaced from'which is a casing tion, through pipe |4c, to the tank l4 and a l9 with a hole 20 in its end. a branch connection 14d to the drip pan 35. 40 Rising from the casing I9 is a small percolator The pipe 36 is a waste pipe employed to carry 40, tube 2| disposed within a ‘pipe 22 the lower end off the drippings from the cooling coil C.

When the fan-wheel is be space 23 is thus formed between the tube 2| and ing rotated at maximunispeed, the blast of air ‘pipe 22 through which the water rises from tank impacting with considerable force on the coil 45 l6. outwardly of the pipe 22 is an insulating ma largely eliminates the super accumulation of ice 45 tank |4 through the opening ll. terial v24. 7 I The wall. Me of the tank i4 is cut away at 25, and over the top of the tank and downwardly on its rearward side is mounted a vapor de?ector, 26 50 which directs the vapor, rising from the perco lator, into opening IS in the tank. An electric heating unit 21 is or may be placed in the water in tank I4 to slightly warm it before entering erated on reduced speeds and conditions are then such as to require clearingthe coils of super ?uous ice, occasionally. ' In operation, the slightly warmed water in tank l4 passes through the opening l'l into tank |6, and a portion. thereof rises into the annular ping and falling into the pan 3!. space 23. . The remainder of the water in tank . l6 passes through the opening 20 into immediate 60 and direct contact with the heating unit by which it~is intensely heated. The quantity or 50 . The de-frosting operation is easily performed by- stopping the ?ow of the refrigerant to the cooling coils, reversing the direction of rotation of the'motor and fan-wheel, ‘and turning on the current to the heater l2. The hot air quickly accomplishes the object sought, the water drip tank l6. 55 thereon, and de-frosting is but seldom required. But the motorand fan-wheel frequently are op . . 7 Now by closing valves 31 and 38 and opening valves 39 and 40 the water in.the drip pan may be forced‘ by the pumpw.

Or, body of water is so small that violent ebullition in case the pump forms no part of the equip takes p1ace,'producing a large amount of vapor ment, the waste pipe 38a (see Fig. 2) may serve and spray which is projected into’ the interior . to carry off the water from the melted ice.

It will be noted that, when the window is low-N 15 ered into the position shown in Fig. 7 it bonds the strip 46 into angular form. The free end of this strip, or the downwardly extending part, due to resistance of the bending stress, exerts a constant pressure on the sash. thereby insuring 20 a tighter weather joint. With the foregoing construction the window may be fully opened or fully closed. , - i 1 On each side of the- apparatus,‘ adjacent the window sash is a‘ ?ller F, made in the form of 25 plates which close these spaces against entrance of air from the outside into the room. The same 3 the fan-wheel is such that it draws air into the box from the indoor end, it serves to very quickly and effectively clear a room ?lled with smoke or disagreeable odors, the latter being forced through the box into the outside atmosphere] Brie?y stated, my device is capable of supply ing ?ltered air for an interior space, previously screened if desired. After being cleaned it‘is susceptible of treatment in various ways, as heat ing, cooling and humidifying, the latter opera 10 tion being conducted by segregating a small body of water from the main supply and applying heat to this smaller quantity. Control over the amount of air to be admitted _ to the interior, the speed at which it is ‘delivered thereto, and the extent to which the ?ltered air ’is moistened are matters which the hereinbefore mentioned control units are capable of handling. The apparatus is simple, e?ici'ent, and effective in changing the air in an interior space so that 20 it is more healthful to live in. What I claim is: 1. An air-conditioning apparatus adapted to be positioned in an interior abreast of an open ing therefrom to the outside atmosphere, com 25 prising a box having an air passageway there- - ‘ general construction with respect to the felt through, an air-?ltering element,,made of min weather-proof strips is'carried out on all sides of ' eral substances, removably disposed in said box, the ?llers, so that air can enter the room through 30 the box 2 only.- - In Fig. 10, I show a slightly different stru - ture for securing the apparatus in the window space. In this instance the box 2 is not secured to any part of the window frame but is simply 35 hung on a cross member ‘which is ?xed. The, box, therefore, may be removed from its posi a motor, air-impelling means to draft air through said air-?ltering element, an an; heater, a small 30 water-vaporizing tank, means for supplying water and maintaining a constant level thereof in said small tank, an atomizing element dis posed in said box adjacent and forwardly of said air heater, a water pump, actuated by said mo tor, adapted to draw water from said water tion by raising it bodily and then withdrawing supply means and force it through said atomizer it from location adjacent the window space. The structure embodies an angle iron 50 held 40 in position by a thin plate 5| which is bent around its horizontal leg 50a, the plate extending , from side to side of the window frame and has ?anged portions extending outward at 5Ia and 5"). To further strengthen and stiffen the structure, another plate 52 is positioned inwardly of the ‘ plate 5| in close contact therewith, an outwardly vprojecting ?ange 52a folding over the ?ange 5la, at the’ bottom, and bending upon itself at‘ the -50 top to form a rail 52b. On the box 2 is secured 2. lug 53 having a de pending ledge 53a, the latter interlocking with the part 52b to prevent inward displacement of the box which is mainly supported by the window 55 stool X. A felt Weatherstrip 54' extends the full length of the window stool and up each end of the ?ller elements, and the weather-joint construction ad jacent the window sash is substantially like that 60 employed in the embodiment shown in Fig. 7. The members Stand 52 are secured to the win dow stools and casings by screws 55. ‘ , In the foregoing description of my improved ventilating and air-conditioning apparatus I have deemed it unnecesary to describe in detail the various elements, such as switches, thermostats, rheostats, etc., used to control and put into action the several electrical units ‘employed in the apparatus. 70 V One of these elements, however, made in the form of a reversing switch R. 8., although a con ventional device, is quite important, as by it the current to the electric motor which drives the fan-wheel may be reversed, rotating the motor 75 in two directions.
