' in air-cooling, ñltering and humidifying appa The apparatuses shown in Figs. 1 and 2 in 55 ratus comprising an air filtering intake unit, an cludes an air ñltering intake unit generally indi 55 2 2,119,038 cated by I1, a blower~ unit -generally indicated by I8 and an under-ground air-cooling means generally indicated by I3. The air iiltering intake unit I1 consists of a Li housing 20, preferably of metal, having a cir cular 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 adapt ed 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 pro 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 manipu 20 lation of the valves 21. In Fig. 1 I show air 15 vided With a circular gate valve 21. 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 under ground 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 pref erably provided with spaced air deñecting walls 35 or fins 28 constituting bailles to an interrupted ñow of the air through the conductor I9 and providing additional heat conductive surfaces in creasing the cooling eñìciency 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 in take 20 and through the cooling conductor I9 45 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 50 and ñltered 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 55 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 00 a series of tubular wall passages I4. Obviously, suitable valves, as for instance valve 36, -may be provided for all air distributing chan nels leading from the blower unit I8 for con water tank 4I which is automatically filled with`Y water through the inlet pipe 42 controlled by a. ñoat 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 hu midiñer 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 10 unit I8 by means of a hot air duct 45 to dis charge 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 15 unit comprising substantially semi-circular pipe sections 48 connected together to provide a wind ing air chamber. To provide suiiicient air-cool ing surface the pipe sections are placed in a series of connected rows providing adjacent wind 20 ing 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 semi 25 circìilar pipe 46B provided with a screened in let 1. Referring now particularly to Figs. 5 and 6, the air filtering intake unit I1 and blower unit I8 are shown diagrammatically in spaced end 30 portions of the basement connected by a wind ing air-cooling conduit 48 which is disposed be tween a double basement iioor of spaced upper and lower sections, respectively 49 and 50. The upper floor section 49 is supported on air-deflect ing walls 5I disposed between the ñoor sections 49 and 5I). ' It is obvious that the conduit 48 can be ar ranged or built in various forms or configurations to provide the desired extended winding air 40 cooling 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 ñoor sections 49 and 50 along the sides and around the ends of the walls 5I. In Fig. 5, 'this 45 air-cooling passage is deñned by the spaced ín termediate parallel walls 5I which extend alter nately from one basement side wall 52 toward and to a spaced distance from the other side Wall 52 to thus provide alternately arranged end pas 50 sages 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 55 the lower end of the blower unit I8. It is also contemplated that a similar air cooling system could be provided under a single basement floor by the use of iron pipes or con crete conduits arranged in a circuitous or wind 3 and 4. In the modifications shown in Figs. '7 and 8 I trolling and regulating the discharge of air to show an air-blower unit I8 similar to that shown 65 the different rooms. Likewise, the air inlet valves 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 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 70 air-cooling means and also show how humidiñ cation 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 75 by capillary action through its immersion in the 60 ing manner, as for instance, that shown in Figs. 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 con 70 nected 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. 75 3 2,1 19,088 I claim: - into said air intake unit from the basement, or l 1.
