AIR COOLING AND DEHYDR'ATING' DEVICE.

Application filed. July 25,

This invention relates to devices for cooling and for partially dehydrating the air contained within enclosures.

One of the objects of the invention is the provision of new and improved means for cooling the air contained in rooms, halls, buildings and the like.

Another object of the invention. is the provision of new and improved beans for partially dehydrating the air contained in enclosures in which the device is employedi A further object of the invention is the provision of new and improved means for reducing the ten'iperaturc in enclosures and more particularly in enclosures occupied by human beings, as dwellings theaters, schools, churches, stores, shops and the like, and sin rultaneously ren'ioving a portion of the moisture contained in said air to thereby render the air in said enclosures more comfortable for human habitation.

Other objects of the invention are the pro vision of a new and improved device for cooling and partially dehydrating air, that is simple in construction, cheap to manutacture, easily assembled, eflicientin operation, and that is not likely to become broken or get out of order.

Other and further objects and advantages of the invention will appear from the following description takenin connection with the accompanying drawings, in which Fig. 1 is a perspective view of the device;

Fig. 2 is a longitudinal section thereof; and

Fig. 3 is a section on line 33 of Fig. 2.

On the drawing the reference character designates a box or container which may be of any desirable form and composed of any suitable material. In the form of the device selected to illustrate one embodimentof the invention, the container 10 is rectangular in form and composed oi sheet metal. The container is provided with an air passage through which air may be caused to move. As shown, the end walls 11 and 1:2

iii

of the container are provided with openings 18 and lt respectively for this purpose. The upper wall 15 of the container may form a lid or closure hinged asat 16. The closure 15 is preferably provided with a handle 17 whereby the same may be lifted to permit access to the interior of the container.

It is a well known fact that warm humid air is more uncomfortable than dry air at the same tempe 'ature. 111 other words, ha-

mid air in warm weather will appear to be or feel several degrees, warmer than dry air at the same temperature, due to the fact that with dry air the skin is cooled by the more rapid evaporation of perspiration. It is also a; matter of common knowledge that the airs capacity for moisture decreases as the temperature decreases. Suitable means are provided tor taking advantage ot'theseprinciples, for not only lowering the temper'-:

ature but also partially dehydrating or removing a portion of the moisture from the air whereby the same will" appear to be at a lower temperature than it actually is. As:

may be employed, that shown being a lump of ice 19 which is placed in said receptacle. The receptacle is comparatively shallow and is less width than the container. Suitable means, as the supporting brackets 21'and 22 are provided for supporting the receptacle 1n spaced'relation to the top, bottom and: side walls of the container whereby air directed through the receptacle by any suitable means as the fan 23 will circulate about the receptacle.

The receptacle is supported so that the upper edge of its front wall 25 will extend across the opening 13. The front wall 25 is arranged at an angle to the bottom wall whereby the same will deflect a portion of the air beneath the receptacle. An impertorate bafile 26 is provided which is adapted to extend upwardly and to either side in engagement with the top and side walls of the container to form a deflector in alinement with the rear wall 30 of the receptacle whereby the air entering the opening 13 above the front .wall 25 will come in contact with the cooling agent and will be compelled to flow over the sides of the receptacle and mingle with the air entering the lower portion of the opening 13. thus assisting in cooling and causing the same to deposit its moisture on the condens ing surfaces of the receptacle.

In order to deflect the air downward on the cooling agent a suitable deflector 27 may he provided. The deflector 27 is preterably hinged as by a detachable hinge 28 whereby the same will automatically adjust itself to the size of the cooling agent. It ice be employed, the rear end of the de liector will. rest on the ice and will move downward as the ice melts The baffle 26 may, if desired he provided with flanges 29 having slots therein for engaging headed pins 31 on the side walls of the container, tor positioning the baflie.

In the operation of the device a cooling agent as ice is placed within the receptacle and a current of air is caused to flow through the container. The air is directed onto the ice and a portion of its heat is absorbed by the ice, thus melting the ice and torming' ice water 33 in the receptacle, which cools the walls of the receptacle to such an extent that the air deflected downward by the front wall 25 and coming in contact with the bottom and side walls of the receptacle will become chilled and deposit its moisture. That portion oi the air current flowing on to the ice will flow over the sides of the receptacle and mingling with the adjacent air will assist in cooling the same. The cool air will pass beneath the battle formed by the rear wall of the receptacle and will flow upward and out into the room or other enclosure through the opening 14 as indicated by the arrows in Fig. 2. The air in the room is not only cooled and partially dehydrated but is caused to be continually circulated by the operation of the fan.

While I have shown a tan for forcing air through the container and have shown a receptacle containing ice within the container, it is understood that this disclosure is by way of example only as any suitable means may be employed for causing the air to flow through said container and any suit- 1 able arrangement of condensing surfaces and means for ciiolingg; the same may be employed without departing from the spirit ot the invention, or scope of the appended claims.

I claim as my invention:

1. In combination, a casing, a container adapted to contain a cooling agent. supported within said container. means for directing a current o t air over and about said container. and a battle plate at the rear oi said container engaging the side walls and top of said casing, said haiile plate terminating short of the bottom wall to form an air passage beneath the same.

2. In combination, a casing" having, openings in its front and rear walls a container in said casing spaced from the side Walls thereof, adapted to contain a refrigerant, means for supporting said container in spaced relation to the rear wall of said c2 .3- inc" and opposite an opening in said front wall, whereby air enteringsaid opening will pass over said container. and an impert'oratc battle extending above said container at the rear portion thereot tor reflecting: the air entering said casinp above said container, back over said refrigerant.

3. In combination. a casing having openinns in its front and rear walls, a refrigerantcontainer, means for supporting said container in spaced relation to the bottom and rear end walls of said casing, means for directing aportion oi the air entering said casing above said container, a battle extending above said container on the rear portion thercoi, and a deflector hinged at the forward portion of said inn and having; its rear end adapted to rest. on the refrigerant in the container for dotlectingr air entering said casing about said refrigerant.
