3 Claims.

This invention relates to improvements in air cooling, conditioning and circulating apparatus which is adaptable for use in homes, industrial plants and other buildings.

One of the objects of my invention is to provide apparatus of this character which shall be simple in construction, low in cost of installation and effective in use for the purposes intended.

An important object of my invention is found in the provision of novel under-ground air-cooling channels, passages or conduits arranged to admit air therethrough to be cooled therein and then discharged into desired points or areas of a building; Vsuch air-cooling means including means for filtering the air of dust and pollen or other matters. and a multiple speed motor-driven fan for regulating and controlling the passage of the air through the under-ground air-cooling channels and into and through the building.

Another object of the invention is found in the novel intake for under-ground air-cooling means which intake includes valve-controlled openings or passages for admitting air into the underground cooling means either from the basement or one of the upper floors of the building or from a point outside of the building; such valves also being arranged to simultaneously admit air into the under-ground cooling means from any two or all of such points.

Another object of my invention resides in the novel construction and configuration of such under-ground cooling means whereby a maximum amount of cooling surface will be provided in a minimum of used or available space. The cooling means can be made of tile, iron pipe, or any other suitable and preferably heat conductive material, as for instance copper or rust-resisting iron or steel.

Another object of the invention resides in the provision of under-ground air-cooling means which will causefa circulation of the air in diiferent directions in a minimum of confined space, as shown for instance in Figs. 3 and 4 where the air passes through interconnected semi-circular pipe sections disposed in a vertical plane and arranged laterally in interconnected sections.

A further object of my invention resides in under-ground air-cooling means of metal having a series of spaced air-deflecting walls or ns to cause a back and forth movement of the air through said air-cooling means and toincrease the area of the surface thereof.

A still further object of the invention resides in air-cooling, ltering and humidifying apparatus comprising an air filtering intake unit, an

1936, Serial No. 73,667

air blower having air humidifying and heating means, and under-ground air-cooling means connecting said units.

Another object of my invention is found in the provision of an air-cooling conduit provided within the construction of the basement floor of a building or under the basement iloor.

Another object of my invention resides in an air-cooling conduit extended preferably in the form of a coil through a body of water, as for illustration, through a coil in a well or cistern.

A still further object of my invention is found in the provision of tubular or rectangular air passages within the'walls'of a building provided with air outlets into therooms and air inlets connected to the blower unit.

With the above and other objects in View, my'

struction and arrangement of the parts and memy bers shown in preferred embodiment in the attached drawings, described in the following specications and particularly pointed out in the appended claims.

Fig. 7 is a sectional plan view of a portion of a basement of a building and showing an air-cooling conduit extending through the water in a cistern or well, and

Fig. 8 is a cross-section taken Fig. 7.

In the illustrations, I0 indicates the walls of a building having a basement fioorll and upper floors I2. 'I'he basement floor I`I is below grade or ground level which is indicated by- I3.

As shown in Fig. 1, the building walls are provided. with tubular `or rectangular ducts indicated respectively by I4 or I5 having outlet openings provided with grills I6.

The apparatuses shown in Figs. 1 and 2 includes an air ltering intake unit generally indion line 8-8 of cated by I1, a blowerunit -generally indicated by I8 and an under-ground air-cooling means generally indicated by I3.

The air iiltering intake unit I1 consists of a housing 20, preferably of metal, having a circular intake 2I extended -through a screened opening 22 into the top of housing 20, a circular intake 23 adapted to admit air from within-the basement of the building, a floor intake 24 adapted to admit air from within the lower room 25 of the building through a grate 26 in the iloor I2 and through an opening in one side of the housing 20.

The air intakes 2|, 23 and 24 are each provided With a circular gate valve 21. As shown in Fig. 1, air may be received into the intake housing 20 through any one of the intakes 2|, 23 or 24, or through any two of such air intakes or through all three of them by simple manipulation of the valves 21. In Fig. 1 I show air being admitted from outside of the building through intake 2I since the valves 21 for the other two intakes are shown in closed position.

As shown in Figs. 1 and 2, the air intake unit I1 is connected at its rear side with an underground air-cooling means shown in the form of a metallic conductor I Il having an extension through the wall of the building and connecting with the housing 20 so that air received into the housing may be passed through the under-ground air-cooling metallic conductor I9 into the blower unit I8. The metallic conductor may be of any suitable metal as for instance copper and preferably provided with spaced air deecting walls or fins 28 constituting bailles to an interrupted ow of the air through the conductor I9 and providing additional heat conductive surfaces increasing the cooling eciency of this unit.

One or more removable air filters 29 of any known design may be mounted within the intake housing to iilter the air before its passage into the cooling conductor I9.

'I'he air is drawn into and through the intake 20 and through the cooling conductor I9 by means of a fan 30 driven by a motor 3I mounted in the housing 32 of the blower unit I8.

If desirable, the blower unit may be provided with an air iilter located between the fan 30 and the outlet of the air-cooling conductor I9.

From within the blower housing 32 the cooled and ltered air may be forcibly discharged through the passage 34 into the conduit 35, which is connected with the rectangular Wall conduit I5, and through the grated opening I6 into the room 25, or the valve 3B may be closed and the air discharged through outlet 31 to other parts of the building or the air may be passed through passage 38 and distributed through a lateral conduit 39 for discharge into the rooms through a series of tubular wall passages I4.

Obviously, suitable valves, as for instance valve 36, -may be provided for all air distributing channels leading from the blower unit I8 for controlling and regulating the discharge of air to the different rooms. Likewise, the air inlet valves 21 may be operated to provide inlet .of air from any one of such inlets, or any two of such inlets or all of the inlets.

In Figs. 3 and 4 I show a modified form of air-cooling means and also show how humidication and air heating means may be provided in the blower unit. One form of humidifying means is indicated by the frame 40 constituting a wick type humidiiier which is kept moistened by capillary action through its immersion in the water tank 4I which is automatically filled with`Y water through the inlet pipe 42 controlled by a. oat valve 43. The wick type humidifier frame is mounted between the blower fan 30 and the air outlets.

A steam or hot water heating coil 44 is shown positioned between the blower fan 3II and humidier frame 40 and in the event a hot air heating unit is employed the hot air chamber of the heater may be connected to the blower unit I8 by means of a hot air duct 45 to discharge heated air into the blower unit I8 into a section located between the air lfilter 33 and the under-ground cool air connections.

Figs. 3 and 4 show an under-ground air-cooling unit comprising substantially semi-circular pipe sections 48 connected together to provide a winding air chamber. To provide suiiicient air-cooling surface the pipe sections are placed in a series of connected rows providing adjacent winding passages for the circulation and cooling of the air as shown diagrammatically in Fig. 4.`

As shown in Fig. 3, the inlet may be in the form of a vertically disposed pipe 4GA extended above the ground surface and terminating in a semicircilar pipe 46B provided with a screened inlet 1.

Referring now particularly to Figs. and 6, the air filtering intake unit I1 and blower unit I8 are shown diagrammatically in spaced end portions of the basement connected by a winding air-cooling conduit 48 which is disposed between a double basement iioor of spaced upper and lower sections, respectively 49 and 50. The upper floor section 49 is supported on air-deflecting walls 5I disposed between the oor sections 49 and 5I).

It is obvious that the conduit 48 can be arranged or built in various forms or configurations to provide the desired extended winding aircooling passage, that is, the path of the air, which is to be cooled, may be arranged to extend in a back and forth or winding manner as between the oor sections 49 and 50 along the sides and around the ends of the walls 5I. In Fig. 5, 'this air-cooling passage is dened by the spaced ntermediate parallel walls 5I which extend alternately from one basement side wall 52 toward and to a spaced distance from the other side Wall 52 to thus provide alternately arranged end passages 48A connecting the ends of the parallel passages 48 one with the other. This back and forth movement of the air will extend from the intake iioor opening 53 at the bottom of the intake unit I1 to the outlet floor opening 54 at the lower end of the blower unit I8.

It is also contemplated that a similar aircooling system could be provided under a single basement floor by the use of iron pipes or concrete conduits arranged in a circuitous or winding manner, as for instance, that shown in Figs. 3 and 4.

In the modifications shown in Figs. '7 and 8 I show an air-blower unit I8 similar to that shown in Fig. `3 discharging cooled air through conduits 35, 31 and 38 to the wall tubes I4 and other parts o-f the building but in the present adaption the air is cooled by its passage through a, coiled pipe 55 disposed within the water of a cistern or well indicated by 56. The air cooling coil 55 is connected at the intake end with an air intake pipe 51 extended above the top 58 of the cistern and the outlet end of the coil 55 is connected with the blower unit I8 by any suitable extended pipe 59 preferably extending underground.
