WITNESSES ZM aff M/ Patented Dec. 26, 1933 UNITED STATES PATENT OFFICE 12 Claims.

This invention relates to apparatus and system for conditioning air in the room of a house, in railway cars or Steamship compartments, buses or other enclosures.

The invention broadly aims to provide an apparatus by virtue of which a room or other enclosure is properly and uniformly cooled or heated and at the same time ventilated independently of or without the necessity of opening the doors or windows.

More particularly, the invention comprehends an apparatus which includes means for conveying and uniformly distributing throughout a room or equivalent enclosure, a supply of fresh heated or cooled air, together with means for receiving and conveying away foul air, so that constant circulation of the air in the room is insured.

As a further feature, the invention embodies the idea of employing the means of conveying and distributing the fresh air, as a means for humidifying the air supply when heated and for conveying off condensation, when the air supply is cooled.

The invention further resides in the provision of an air conditioning apparatus or system of the indicated character which is comparatively simple in its construction and mode of operation, inexpensive to produce, install and maintain in Working condition, and which is highly eicient in its purpose.

With the above recited and other objects in view, reference is made to the followingV specification and accompanying drawings, in which there is illustrated several preferred embodiments of the invention, while the claims denne the actual scope thereof.

In the drawings:

Figure 1 is a fragmentary horizontal sectional view of an air conditioning apparatus constructed in accordance with the invention and illustrating the same installed in a room or equivalent enclosure.

Figure 2 is an enlarged fragmentary sectional perspective View of one corner of the apparatus.

Figure 3 is a vertical sectional view diagrammatically illustrating the apparatus.

Figure 4 is a plan view with parts shown in section illustrating the apparatus as applied to a railway car or other vehicle.

Referring to the drawings by characters of referance, the apparatus includes a hollow molding designated generally by the reference character A which is designed to be applied to the wall of the enclosure at a point spaced below the ceiling. The molding A includes a rearwall 5, a front wall 6 which may be variously contoured to lend thereto the desired ornamentality, a bottom wall 7 and a top wall 8. 'I'he molding is sub-divided into upper and lower ducts 9 and 10 by horizontal partition 11 and the upper wall 8 is formed with 60 a series of inlet openings 12 communicating with the duct 9 and designed to receive therethrough foul air which is drawn oil? from the duct 9 by one or more pipes or conduits 13 which communicate with the inlet of an exhaust pump or fan 14. The front wall 6 is formed with a plurality of openings 15 for discharging fresh air fromvthe duct 10, which air is supplied thereto through a pipe or conduit 16 leading from the outlet 17 of a fan or blower 18 which draws in fresh air 70 from outside of the enclosure. The fresh air duct 10 has extending therethrough a conduit or pipe 19 which leads to and may be optionally connected with a refrigerator unit 20 or a heating unit 21 depending upon whether the air supply 'l5 is to be cooled or heated. As illustrated, the conduits or pipes 22 lead from the conduit or pipe 19 and are provided with branches 23 and 24, the former leading through the refrigerator unit 29 and the latter through the heating unit 21. Valves 25 and 26 control the optional establishment of communication oi' the conduit or pipe 19 with the refrigerating and heating units.

When the apparatus is employed for supplying a cooled fresh air supply to the room or enclosure, the lower portion of the molding A serves as a trough T for the reception of condensation which forms on the exterior oi' the pipe or conduit 19. When the apparatus is employed to supply heated fresh air to the room or enclosure, the lower portion of the molding A provides a trough T for Water for moistening or humidifying the heated air discharged or supplied to the room or enclosure. In order to optionally convey oi the condensation from the trough T or supply water for humidifying the heated air, a pipe or conduit 27 communicates with the lower trough-forming portion of the molding A and leads therefrom to branch pipes 28 and 29 connected respectively with a drain 30 and a water supply 31, valves 32 and 33 being provided in said branches for selectively cutting off or establishing communication between said branches and the pipe 2'7.

In order to strengthen the molding at the corners of the room or enclosure, corner pieces, such as castings 35, are located within the lower compartment 10 and snugly t the compartment. The corner pieces 35 in addition to strengthening the corners valso serve as unions for connecting and establishing communication between the sections of the conduits or pipes 19. This is accomplished by providing the corner pieces with a passage 36 into which theextremities of adjacent pipe sections 19 are threaded. In order to permit the condensation or humidifying water to flow past the corner pieces, the lower edge thereof is grooved as at 37.

Where the apparatus or system is applied to a vehicle, advantage may be taken of the motion of the vehicle to promote circulation for the purpose of supplying fresh air and expelling foul air. This is illustrated diagrammatically in Figure 4 of the drawings wherein the lower duct 10 of the molding A is provided with a forwardly directed inlet 40 which by virtue of the forward movement of the vehicle causes the fresh air to flow through the duct 10 and to be introduced and distributed throughout the vehicle enclosure. Also in this arrangement the upper duct 9 is provided with a rearwardly disposed outlet 41 which by virtue of the forward movement of the vehicle induces a suction in the outlet for drawing off the foul air through the duct inlets 12.

It should be noted that in connection with the foul air duct 9 and the fresh air duct 10, the inlet openings 12 of the former and the outlet openings 15 of the latter may be of graduated size in accordance with their proximity to the outlet of the former and the intake of the latter so as to insure uniform action.

While there has been illustrated and described several preferred embodiments or uses of the invention, it is to be understood this is merely illustrative of certain forms of the invention and is not intended as a limitation upon the scope of the claims.
