2 Claims. (01. 25-1-9) This invention relates to a novel air conditioning plant which is especially, but not necessarily, adapted for domestic usage and which is constructed to. performasan air cooling system in ing system during the winter or colder months.

My primary aim is to provide a single structure for performing both operations, which structure is capable of installation in the ordinary home I [Q and constructed to accommodate a suitable charmatic type showing the manner in which the complete operative system is installed in the cellar and associated with superposed rooms.

Figure 2 is a viewin section and elevation illustrating the principal features of construction as designed in accordance with the present invention.

Figure 3 is a top plan view of theair intake and preparing device or unit.

Figure 4 is a central vertical sectional view through said unit.

Figure 5 is a view similar to Figure 2, the section being at approximate right angles to Figure 2 to show the internal association of parts more plainly.

35 Figure 6 is a plan view of a supporting spider for the fan motor.

Attention is first invited to Figure lfwherein it will be observed that the air trapping and distributing casing or enclosure is distinguished byv the numeral 7. This is of appropriate proportions, material and shape. It may resemble an ordinary cellar furnace. In fact, it does resemble such a furnace in that it includes a hinged door 8 to permit either the heating or cooling 5 medium to be inserted, and it is provided at its bottom with a refuse removal door 9, by way of whichashes and used ice water may be disposed of. Then too, at the top I provide outlet collars 10 through which the conditioned air passes'into conveying pipes or the like 11 where it is conveyed into the upper rooms and discharged by way of an appropriate register or the like 12 into the summer and warm weather and as an air heatcasing where it enters the casing as shown in Figures 1 and 2,

Referring now to Figure 2, I call attention to the central horizontal partitioning plate 15 which divides the easing into upper and lower chambers 16 and 17 respectively. The chamber 17 serves to accommodate the air intake pipe 14 and the associated air preparing device or unit 18. This is supported or hung in the chamber 17 from the partitioning plate 15 as illustrated in the drawings. Moreover, as shown in Figure 4, this particular device embodies a conical receptacle '19 formed with an integral cylindrical cup-like fan housing 20.

In the fan-housing is a spider ring 21 and attaching arms 22 for said ring, the ring serving to support a conventional electric motor 23, for driving the rotary fan 24. The fan sucks air in through the inlet nipples 25 from the pipes 14 where it is pre-treated before entering the chamber 16. In the first place, the air comes into contact with an electric refrigerating coil 26 of appropriate construction. Then it is drawn up by the fan and the air currents project against the conical hood 27. This hood is attached in spaced relation by brackets 28 to the upper end of the cylindrical housing 20 whereby to provide for discharge of the air and the hood is of appropriate diameter as to overhang the housing in the manner shown. The hood serves essentially as as a shield and water spreader. In fact, a water delivery pipe 29 serves to drop water onto this shield so that the incoming air is passed through the film of water and washed and moistened and then driven under pressure by way of the fan 24 into the final conditioning chamber 16. It will be noticed in this connection that the numeral 30 designates a drain port'and 31 a similar drain port to which pipes 30a and 31a connect in order to carry the used water to an appropriate point of disposal. Incidently, this air washing and moistening means are used when the plant is employed for either heating or cooling purposes. Manifestly, however the cooling unit 26 is turned on only when the structure is used-as an air cooling system.

As the air passes through the device 18 into the chamber 16 it is then subjected to the action of the air conditioning unit which is selectively used either for air cooling or heating purposes. A working exemplification of this air modifying unit is illustrated in Figure 2 in the form of an appropriate box-like container 33 of appro== priate proportions and shape, the same having 11% the container is provided as shown in Figure 5 with a coal chute 36 and at a diametrically opposite point with a smoke outlet pipe 37 joined to the associated flue 38. The bottom of the casting forming the container 33 is formed'mto a sort of a pan 39 having an appropriately shaped depression 40 which defines a trough. This,

trough communicates with a discharge pipe 41 leading down to the refuse box or pit 42.

The trough and pipe 41 obviously serve to permit ashes to gravitate into the ash pit when coal is used as a source of heat. When however ice is used a collection pan or suitable receptacle (not shown) is placed in the pit for periodical emptying.

The gist of the invention is found in the provision of a furnace-like casing '7 provided with air conditioned outlet 10 to deliver the air by way of ducts 11 to the room registers 12, whether the air be cold or hot, whichever is desired. Secondly, novelty is predicated upon the use of the floor registers 13 and return pipes 14 for delivering the air intothe preconditioning or preparing device 18. As before stated, this device serves to wash the air and moisten the air and when employing a cooling or refrigeratingunit 26 serves to additionally cool the air.

After the air is thus pre-treated, it enters the chamber 16 where it is subjected to the action of the modifying and conditioning unit 33, which,

as before stated, may use either ice or coal in orderto acquire the desired results.

All of the aforesaid features have been carefully selected and mechanically co-ordinated in appropriate order to progressively handle the air and to provide a single structure which may be employed either as a cooling system or a heating system, according to climatic conditions.

menace It is thought from the foregoing description that the advantages and novel features of the tition in said casing dividing it into upper and lower compartments, means in the upper compartment in alinement with said aperture for either heating. or cooling the air passing through said upper compartment, and means in the lower compartment for pre-treating the air before it is allowed to pass into said upper compartment, said last-named means being in communication with the air intake means and including an inverted conical receptacle carrying a fan housing, a motor driven fan in said housing, a refrigerating unit in said housing, a hood-like shield supported on said housing at the upper portion thereof, and a water delivery pipe cooperating with said shield.

2. An air conditioning plant ofthe class described comprising .a casing having air intake and discharge means, a centrally apertured partition in said casing dividing it into upper and lower compartments, means in the upper compartment in alinement with said aperture for either heating or cooling the air passing through said upper compartment, and means in the lower compartment for pre-treating the air before it is allowed to pass into said upper compartment, said last named means being in communication with the air intake means and including a casing having its top open and-in communication with the upper compartment through said aperture,

a fan housing in the lower part of the last mentioned casing, a motor driven fan in said housing, a hood-like shield supported on said housing at the upper portion thereof, and a liquid delivery pipe for delivering liquid to said shield.
